Description

This invention relates to a program you and game system in which the player character that the player is operated to perform a game of action games, etc. to subdue the enemy character continue to clear the mission.

There is a hunting action game as a game that is currently popular with many people.
In the hunting action game, the game progresses when the player character operated by the player subjugates a monster that is an enemy character.

  The player character goes to the field (hunting ground) where the target monster lives and fights with the monster. A field is formed from about 10 game stages (hereinafter, stages), and monsters live in the field while moving between stages. Monsters move only between stages that are predetermined by their characteristics. For example, a monster that lives in water moves only to a stage with water. The player character patrols the field, finds a monster, and fights the monster.

  In such a game, there may be multiple monsters in the field at the same time, but each monster moves through a stage with its own action pattern, so if the destination stage matches, multiple monsters will move in the same stage. A head monster may stay (Non-Patent Document 1).

An optical disk 4 which is an example of a replaceable storage medium is set in the game apparatus 10, and a removable memory card 5 for storing game save data and the like in a non-volatile manner is mounted as necessary. The game apparatus 10 is provided with a power ON / OFF switch that is a main power source of the game and an eject switch for attaching and detaching the optical disk 4.

  The controller 7 is an apparatus that is operated by a player and transmits an operation signal indicating the operation content to the game apparatus 10. The game apparatus 10 performs control such as starting and ending the game in accordance with the operation signal transmitted from the controller 7 and advancing the game. Communication between the controller 7 and the game apparatus 10 is performed wirelessly. As a communication unit for this communication, the controller 7 includes a communication unit 75 (see FIG. 4), and the game apparatus 10 includes a receiving unit 36a (see FIG. 2). One to four controllers 7 can be wirelessly connected to one game apparatus 10.

  Light emitting units 8L and 8R are attached to the left and right upper surfaces of the monitor device 9 to inform the controller 7 of the position of the monitor device 9. The light emitting units 8L and 8R each incorporate an infrared LED, and emit light with infrared rays while the game apparatus 10 is in operation.

  Next, the functional configuration of the game apparatus 10 will be described with reference to the block diagram of FIG. In FIG. 2, the game apparatus 10 includes a CPU (Central Processing Unit) 30 that executes various programs. The CPU 30 executes a boot program stored in a boot ROM (not shown), initializes a memory such as the main memory 33, and the like, and then executes a game program stored in the optical disc 4 according to the game program. Game processing and the like. A GPU (Graphics Processing Unit) 32, a main memory 33, a DSP (Digital Signal Processor) 34, and an ARAM (Audio RAM) 35 are connected to the CPU 30 via a memory controller 31. In addition, a controller I / F (interface) 36, a video I / F 37, an external memory I / F 38, an audio I / F 39, and a disk I / F 41 are connected to the memory controller 31 via a predetermined bus 42. The receiving unit 36a, the monitor device 9, the external memory card 5, the speaker 9a, and the disk drive 40 are connected to each other.

  The GPU 32 performs image processing based on a command from the CPU 30, and is configured by a semiconductor chip that performs calculation processing necessary for displaying 3D graphics, for example. The GPU 32 generates an image of each frame (two-dimensional image by a known perspective projection method) in a three-dimensional virtual space (game space) using a memory dedicated to image processing (not shown) and a partial storage area of the main memory 33. Then, a game image generated by combining an image such as a cursor with this image is output to the monitor device 9 (display 9b) via the memory controller 31 and the video I / F 37. The main memory 33 is a storage area used by the CPU 30 and appropriately stores a game program read from the optical disc 4 and various data.

  The DSP 34 processes sound data generated by the CPU 30 when the game program is executed, and is connected to an ARAM 35 for storing the sound data. The ARAM 35 is used when the DSP 34 performs a predetermined process (for example, storage of a pre-read game program or sound data). The DSP 34 reads the sound data stored in the ARAM 35 and outputs the sound data to the speaker 9 a provided in the monitor device 9 via the memory controller 31 and the audio I / F 39.

  The memory controller 31 controls the overall data transfer and is connected to the various I / Fs described above. The receiving unit 36a is connected to the memory controller 31 via the controller I / F 36. As described above, the reception unit 36 a receives transmission data from the controller 7 and outputs the transmission data to the CPU 30 via the controller I / F 36 and the memory controller 31. A monitor device 9 is connected to the video I / F 37. An external memory card 5 is connected to the external memory I / F 38 and can access a backup memory or the like provided in the external memory card 5.

  A speaker 9 a built in the monitor device 9 is connected to the audio I / F 39. The speaker 9a outputs sound data read from the ARAM 35 by the DSP 34 and sound data directly output from the disk drive 40. A disk drive 40 is connected to the disk I / F 41. The disk drive 40 reads data stored on the optical disk 4 arranged at a predetermined reading position, and outputs the data to the bus 42 and the audio I / F 39 of the game apparatus 10.

Next, the controller 7 will be described with reference to FIG.
The controller 7 has a housing 71 formed by plastic molding, for example. The housing 71 has a substantially rectangular parallelepiped shape whose longitudinal direction is the front-rear direction, and is a size that can be gripped with one hand of an adult or a child as a whole.

  A cross key 72 c is provided on the center front side of the upper surface of the housing 71. The cross key 72c is a cross-shaped four-direction push switch, and operation portions corresponding to four directions (front and rear, left and right) indicated by arrows are arranged on the cross-shaped projecting piece at intervals of 90 °. When the player presses the operation unit in any direction of the cross key 72c, an operation signal indicating the direction is transmitted from the controller 7 to the game apparatus 10.

  A large number of button switches are provided behind the cross key 72 c on the top surface of the housing 71, and when each button is turned on, a corresponding operation signal is transmitted from the controller 7 to the game apparatus 10. Among these button switches, the A button 72a is provided in the forefront (closer to the cross key 72c).

  On the other hand, a recess is formed on the lower surface of the housing 71. The recess on the lower surface of the housing 71 is formed at a position where the player's index finger or middle finger is positioned when the player holds the housing 71. A button switch 72b is provided on the rear inclined surface of the recess. The button switch 72b is an operation unit that functions as a B button.

  The button switch 72h provided on the front side of the cross key 72c on the upper surface of the housing 71 is a power switch for turning on / off the game apparatus 10 main body remotely.

  In addition, an imaging element 743 (see FIG. 4) for capturing an image in front of the controller 7 is provided on the front surface of the housing 71. The imaging element 743 constitutes a part of the imaging information calculation unit 74 (see FIG. 4). When the controller 7 is supported toward the monitor device 9, the image sensor 743 images the light emitting units 8 </ b> L and R provided on the upper surface of the monitor device 9. The imaging information calculation unit 74 detects the orientation of the controller 7 based on the imaging positions of the light emitting units 8L and R in the imaging element 743.

Next, the internal configuration of the controller 7 will be described with reference to the block diagram of FIG.
In FIG. 4, the controller 7 includes a communication unit 75, an acceleration sensor 701, and a vibrator 704 in addition to the operation unit 72 and the imaging information calculation unit 74 described above.

  The imaging information calculation unit 74 includes an infrared filter 741, a lens 742, an imaging element 743, and an image processing circuit 744. The infrared filter 741 allows only infrared light to pass through from light incident from the front of the core unit 70. The lens 742 condenses the infrared light that has passed through the infrared filter 741 and outputs the condensed infrared light to the image sensor 743. The image sensor 743 is a solid-state image sensor such as a CMOS sensor, for example, and images the infrared rays collected by the lens 742. Therefore, the image sensor 743 captures only the infrared light that has passed through the infrared filter 741 and generates image data. Image data generated by the image sensor 743 is processed by an image processing circuit 744. Specifically, the image processing circuit 744 processes the image data obtained from the image sensor 743 to detect light from the high-luminance portion, that is, the light from the light emitting units 8L and R, and generates coordinate data indicating their position coordinates. Output to the communication unit 75.

  The acceleration sensor 701 is an acceleration sensor that detects acceleration on three axes of the controller 7 in the vertical direction, the horizontal direction, and the front-rear direction. Data indicating the acceleration detected by the acceleration sensor 701 is output to the communication unit 75.

  The communication unit 75 includes a microcomputer (microcomputer) 751, a memory 752, a wireless module 753, and an antenna 754. The microcomputer 751 controls the wireless module 753 that wirelessly transmits transmission data while using the memory 752 as a storage area during processing.

  An operation signal (key data) from the operation unit 72, an acceleration signal (acceleration data) from the acceleration sensor 701, and coordinate data from the imaging information calculation unit 74 are output to the microcomputer 751. The microcomputer 751 temporarily stores the input data (key data, acceleration data, coordinate data) in the memory 752 as transmission data to be transmitted to the receiving unit 36a.

  Here, the wireless transmission from the communication unit 75 to the receiving unit 36a is performed every predetermined cycle, but since the game processing is generally performed in units of 1/60, a shorter cycle than that is performed. It is necessary to send in. When the transmission timing to the receiving unit 36a comes, the microcomputer 751 outputs the transmission data stored in the memory 752 as a series of operation information and outputs it to the wireless module 753. The wireless module 753 radiates operation information from the antenna 754 as a radio wave signal using a carrier wave having a predetermined frequency.

  The vibrator 704 may be a vibration motor or a solenoid, for example. Since the vibration is generated in the core unit 70 by the operation of the vibrator 704, the vibration is transmitted to the hand of the player holding it, and a so-called vibration-compatible game can be realized.

≪Description of game program≫
Next, a game program executed on this game apparatus will be described. This game program is a so-called hunting action game, where a player character operated by a player becomes a village resident, and various actions such as subjugation / capture of enemy characters (monsters) requested in the village, transportation / collection of items, etc. It is a game that challenges missions (quests). There are multiple quests, but many quests are aimed at subjugating monsters. In the quest, various fields (hunting grounds) such as forests, hills, volcanoes, and frozen soils are prepared, and the player character is equipped with weapons and armor and heads to the field to fight the monsters. The player accomplishes the quest by hunting monsters and proceeds with the game.

  The various fields defined for each quest have a shape as shown in FIG. 6, for example, and are formed from about 10 stages. Then, the player character can freely move in each game stage (hereinafter referred to as “stage”), and can go around the field. The monster also moves in each stage. However, since only the stage determined in advance according to the characteristics is moved, the stage that can be moved differs depending on the monster. For example, monsters that live in water move only on stages with water.

  In addition, since the monster randomly moves in the stage of the action range, the movement route is different for each quest. The monster repeats the movement of the stage every time a predetermined time elapses, starting from a preset stage at the start of the quest, and circulates in the field many times during the quest.

  In this game, there is a quest that targets multiple monsters. In that case, multiple monsters are generated at the start of the quest, and each monster moves on the stage. In addition, even if there is one monster to be subjugated, there is a quest in which a new monster that is not an object of subjugation occurs after the quest starts. In this case as well, multiple monsters move on the stage after a new monster is generated.

  In this way, if there are multiple monsters in the field and the stage is moving, if the movement stage of each monster matches during the game, multiple monsters will “stay” on the same stage. . At this time, “escape lottery”, which is a “competition lottery” in which one monster escapes from the other monster and moves to another stage based on a predetermined condition. As a result, the power relationship between a plurality of monsters can be expressed more realistically, and the player's strategy options can be expanded. The escape lottery will be described later with reference to FIG.

  In the present embodiment, the fact that a monster exists on a finite time stage is expressed as “stay”. This “stay” corresponds to “existence” in the claims. In the present embodiment, the “specific area” in the claims is described as a “game stage”.

  A game system as shown in FIG. 5 can be functionally realized by causing the above-described game device to read a game program for executing such a game. The game system includes an operation detection unit 50, a game progress control unit 51, a drawing processing unit 57, and the like. The game progress control unit 51 includes a player character control unit 52, a non-player character control unit 53, and a game space control unit. 55 is included. The non-player character control unit 53 includes a monster movement control unit 54, and the game space control unit 55 includes a game stage control unit 56.

  The operation detection unit 50 includes a data processing unit such as the CPU 30 and the GPU 32 and the controller 7, detects various operations of the player, and transmits them to the game progress control unit 51. The game progress control unit 51 includes a data processing unit such as the CPU 30 and the GPU 32, generates a virtual game space and characters, and changes the above-described game space according to the player's operation and the passage of time. The game is advanced by performing processing such as activating the character.

  The player character control unit 52 generates a player character in the game space and controls its activity based on operation information input from the operation detection unit 50. The non-player character control unit 53 generates a non-player character that moves in the game space and controls its activity. The main non-player character is an enemy character monster that fights against the player character. The monster movement control unit 54 is a control unit including the competition control means of the present invention, and controls the monster stage movement performed every predetermined time and the escape lottery performed when the monsters compete.

  The game space control unit 55 generates a game space for the field selected based on the operation information input from the operation detection unit 50, and controls the environment such as weather and day / night changes in the game space. The game stage control unit 56 further generates a plurality of game stages in the field generated by the game space control unit 55 and controls the environment. The drawing processing unit 57 includes a data processing unit such as the CPU 30 and the GPU 32, generates a game image in which the game space, characters, and the like generated by the game progress control unit 51 are projected on a two-dimensional screen, and outputs the game image to the monitor 9b.

  Hereinafter, the stage movement process performed by the monster movement control unit 54 will be described with reference to FIGS.

  FIG. 6 is a configuration diagram of a field configured by a plurality of stages generated by the game stage control unit 56. In the field of the figure, there are 12 stages having various environments such as lakes, grasslands and caves. When the quest starts, a monster is generated on any stage in this field, and the monster moves to another stage when the stay time shown in FIG. 7 has elapsed.

  Further, when a monster meets another monster on the staying stage, whether or not he (the monster himself) moves (runs away) to another stage is determined based on the condition (probability) shown in FIG. An escape lottery is held. In addition, this escape lottery is performed for both monsters. That is, for other monsters as well, it is determined whether or not you (the other monsters themselves) move to another stage based on the conditions shown in FIG.

  FIG. 7 is a diagram showing a stage stay time table. This table is a table in which the stay time when the monster is staying alone at the stage of the action range (stages 2 to 5, 7, and 10) is set.

  In this table, the normal stay time is the stay time when the monster stays alone on the stage and is not fighting the player character. Regardless of the stage in which the monster is staying, if it is not fighting with the player character, the monster always moves to the next stage 30 seconds after it has moved to that stage. On the other hand, the battle stay time is the stay time when the monster is fighting with the player character. When the monster is fighting with the player character, the monster stays on that stage until the battle staying time, and then moves to the next stage.

  When the staying time has passed and the monster is determined to move to the stage, the “destination stage lottery” for determining the destination stage is performed, and the monster moves to the winning stage. The destination stage lottery will be described later with reference to FIG.

  Even if the staying time has not passed, if another monster stays on the same stage, an escape lottery will be performed to escape that monster from the other monster, and the monster will move to another stage with a predetermined probability. . Hereinafter, in this embodiment, the escape lottery based on “rank” will be described.

  The rank is a parameter indicating an ability (combat strength), and monsters are classified by rank. Four ranks, S rank, A rank, B rank, and C rank, are set from the top. When two (multiple) monsters stay on the same stage, the ranks of the monsters are compared, and a run-away lottery is performed so that the lower-rank (weaker) monster moves with a high probability. In other words, the lower rank monsters are easier to escape from the stage. Hereinafter, this escape lottery is referred to as “escape lottery (1)”.

  FIG. 8 is a diagram showing an escape lottery probability table used for the escape lottery (1). In this table, escape lottery probabilities are set based on the ranks of escaping monsters (lottery target monsters) and comparison target monsters (other monsters staying on the same stage). The escape lottery probability is the probability that the escaped monster will escape from that stage and move to another stage.

  The escape lottery probability is set to 40% when the escaping monster has a lower rank than the monster to be compared, and 20% when the escaping monster has the same rank as the monster to be compared. On the other hand, since the higher rank (stronger) monster does not escape from the lower rank (weaker) monster, the escape lottery probability is 0 when the escaping monster is higher rank than the monster to be compared. % Is set.

  In this way, when multiple monsters meet on the same stage (when they compete), the monsters' power relationships and ecosystems are realistically played in the game by performing a lottery run for each monster and escaping with a predetermined probability. Can be expressed in In addition, the player can fight using the power relationship and ecosystem between monsters, and the options for strategy can be expanded and the battle can be advanced advantageously.

  For example, even if multiple monsters stay on the same stage, it is possible to wait for one monster to escape and fight the other monster, or follow the escaped monster and fight the monster. In addition, strategies that give priority to attacking monsters that have a low or no chance of escaping, and that can be traced to monsters that have a high probability of escaping (paintballs, transmitters, etc.) Can perform a typical battle. Moreover, the description of the monster's power relationship can be emphasized more, and a game that never gets tired can be provided to the player.

  FIG. 9 is a diagram showing a destination stage determination table used for determining a destination stage of a monster. This table is used for “destination stage lottery” for determining the destination stage when the monster is determined to move on stage due to the elapse of staying time or escape lottery. This table is set for each monster and for each field.

  FIG. 9A shows a destination stage determination table at the start of the quest. In this table, the generation stage at the start of the quest of the monster, the destination stage and its probability are stored in association with each other. This monster occurs on stage 10 or stage 2 at the start of the quest in this field. When a monster occurs on stage 10, it moves to stage 4 or stage 7. The winning probability of each destination is 60% for stage 4 and 40% for stage 7. For example, when stage 4 is won, the monster moves from stage 10 to stage 4. After the first movement, a destination stage lottery is performed based on the table in FIG.

  FIG. 5B shows a destination stage determination table during the quest. This table stores the stage where the monster is currently staying, the stage of the movement source, the movement destination stage by the next movement, and the probability thereof. In this field, this monster has stages 2 to 5, 7, and 10 as action ranges, and a destination stage is set for each stage in this action range.

  For example, if the monster has moved from stage 10 to stage 4 as in the above example, the current stage is stage 4 and the source stage is stage 10, so this table allows the monster to be stage 2 or Move to stage 10. The winning probability of each destination is 90% for stage 2 and 10% for stage 10. For example, if stage 2 is won, the monster moves from stage 4 to stage 2. Thereafter, in each destination stage, the destination stage lottery is similarly performed based on the table.

  FIG. 10 is a flowchart for explaining the “stage movement process” performed by the monster movement control unit 54. The stage moving process is a process of determining whether or not to move the monster on a predetermined time interval and, if it is determined to move, performing a destination stage lottery and moving the monster to the selected stage. When multiple monsters stay on the same stage during the stage movement process, the above-described escape lottery (1) is performed.

  The monster is provided with a state (status) that is a behavior form of the monster according to the game situation, and either “normal state” or “battle state” is set. The normal state is a state in which an enemy (player character) has not been found and a normal action such as walking or looking around is performed. The battle state is a state where an enemy (player character) has been found and a battle action such as biting or breathing is performed.

  In the stage movement process, the stage movement conditions differ depending on the state set for the monster. If the monster is in “battle state”, it will move to the next stage when the battle stay time has passed or when it is won by the runaway lottery (1). On the other hand, if the monster is in the “normal state”, the monster is always moved to the next stage after 30 seconds.

  Hereinafter, a description will be given with reference to the flowchart of FIG. First, it is determined whether or not the monster is in battle with the player character (battle state) (S10). If it is not in a battle (if it is a normal state) (NO in S10), it is determined whether or not the staying time of the lottery target monster at that stage is 30 seconds (S11). If the stay time is not 30 seconds (NO in S11), the stage moving process is terminated. On the other hand, when the stay time is 30 seconds (YES in S11), a destination stage lottery (FIG. 9) is performed (S12), and the monster is moved to the stage determined by the lottery (S13).

  When the monster is in battle (battle state) (YES in S10), it is determined whether or not the battle stay time has elapsed, that is, whether or not the stay time of this monster in this stage is equal to or longer than the battle stay time ( S14). When the battle stay time has elapsed (YES in S14), the monster moves to the next stage unconditionally, so the destination stage lottery (S12) and stage movement (S13) are performed. If the battle stay time has not elapsed (NO in S14), it is determined whether there is another monster on the same stage (S15). If there is no other monster on the same stage (NO in S15), the stage moving process is terminated.

  On the other hand, if there is another monster on the same stage (YES in S15), it is determined whether or not the staying time of the lottery target monster in that stage is 30 × n seconds (n is an integer) (S16). If the stay time is not 30 × n seconds (NO in S16), the stage moving process is terminated, but if the stay time is 30 × n seconds (YES in S16), the escape lottery (1) (FIG. 8) is performed. (S17). When the winning is made (YES in S18), the destination stage lottery (S12) and the stage movement (S13) are performed. If not won (NO in S18), the stage moving process is terminated.

  As another embodiment, the monster escape lottery probability may be changed by the “predetermined action” of the player character. Predetermined actions include attacks such as punching and kicking, casting spells, and using items. Hereinafter, it is described as “predetermined action” that the player character throws (uses) a koji ball (ball with a different odor) that is one of the items.

  When the player character throws a “Koyashidama” and hits it against a monster, a lottery is performed using the escape lottery probability table (FIG. 11) with a higher probability than the escape lottery (1). The “movement process” (FIG. 12) is performed. With this process, if the player character uses an item (a ball of balls), the monster can be made to escape more easily than the escape lottery (1).

  In the stage moving process using the ball, not only the escape lottery (hereinafter referred to as “escape lottery (2) -1”) when there is a monster to be compared on the same stage, but the monster to be compared is on the same stage. If there is not, an escape lottery (hereinafter, “escape lottery (2) -2”) is also performed. As a result, even when there is only one monster on the same stage, the monster can escape, and the effect of the koji ball can be expressed. Further, different escape lottery probabilities are set for the escape lottery (2) -1 and the escape lottery (2) -2 to express how the effect of the ball is changed.

  FIG. 11 is a diagram showing an escape lottery probability table used for escape lottery (2) -1 and (2) -2 performed in the stage moving process using the ball.

  (A) in the figure is an escape lottery probability table when there is a monster to be compared on the same stage (escape lottery (2) -1). The rank of the monster to be escaped and the rank of the monster to be compared Based on the above, the escape lottery probability is set.

  The escape lottery probability is set to 80% when the escaping monster has a lower rank than the monster to be compared, and 50% when the escaping monster has the same rank as the monster to be compared. 1) The probability is set higher than that in FIG. On the other hand, even if the monster on the escape side is ranked higher than the monster to be compared, the escape lottery probability is set to 20%, and even if it is a higher rank monster, it can be escaped if it hits the ball. Has been.

  Figure (B) is the escape lottery probability table when there are no monsters to be compared on the same stage (Escape Lottery (2) -2), and the rank of the monster to be escaped and the rank of the monster to be compared Based on the above, the escape lottery probability is set.

  Escape lottery probability is set to 20% if there is no monster to be compared, regardless of the rank of the escaping monster, and if a ball is hit, it will escape even if there is only one monster on the stage Is set to get.

  In the runaway lottery (1), the lottery is repeated every time a certain time (30 seconds) elapses. In the runaway lottery (2) -1 and (2) -2, the lottery is drawn immediately after the ball is hit. A lottery will be held after 15 seconds. Also, an effect such as yellow smoke indicating that the ball has been hit for 15 seconds is displayed on the game screen. As a result, it is possible to express how the effect disappears after the effect of the ball is continued for a certain time (15 seconds).

  Escape lottery (2) -1 and (2) -2 are performed only when the monster is in battle with the player character (monster is in combat), and when the battle is not in progress (normal) Without setting, it is set to escape with a probability of 100% immediately after hitting the ball.

  FIG. 12 is a flowchart for explaining the stage moving process using the koji ball performed by the monster movement control unit 54. The stage moving process using the ball is a process of moving the monster on the stage with a predetermined probability immediately after the player character throws the ball and hits the monster, or after 15 seconds. This process is performed in parallel with the normal stage movement process shown in FIG. That is, for example, for each monster, the process of FIG. 10 and this process are continuously executed for each frame (1/30 second). However, when a monster moves in either process, the other process ends together.

  Hereinafter, a description will be given with reference to the flowchart of FIG. First, it is determined whether or not it is immediately after the ball is hit or whether or not 15 seconds after the ball is hit (S40). If it is not immediately after the hit or 15 seconds later (NO in S40), the stage moving process with the ball is finished. If it is immediately after the hit or 15 seconds later (YES in S40), it is determined whether or not the monster is in battle (battle state) (S41). If it is not in battle (in normal state) (NO in S41), the destination stage lottery (S42) and stage movement (S43) are performed in order to move with a probability of 100%.

  On the other hand, if the monster is in battle (battle state) (YES in S41), it is determined whether there is another monster on the stage (S44). If there is no other monster (NO in S44), a run-away lottery (2) -2 (FIG. 11B) is performed (S45). If it is not won (NO in S46), the stage moving process by the ball is finished. If it is won (YES in S46), the destination stage lottery (S42) and the stage moving (S43) are performed.

  On the other hand, if there is another monster (YES in S44), the escape lottery (2) -1 (FIG. 11A) is performed (S48). If it is not won (NO in S49), the stage moving process using the ball is finished. If it is won (YES in S49), a destination stage lottery (S42) and a stage move (S43) are performed.

  In addition, only the stage moving process by the kneading ball is performed for 15 seconds after the hitting the kneading ball, and the “kneading ball state” in which the normal stage moving process shown in FIG. 10 is not performed may be provided. Then, when the lottery after 15 seconds has not been won, a normal stage moving process may be performed.

  Further, in the above-described stage moving process using the ball, the escape lottery probability immediately after hitting the ball is made the same as the escape lottery probability after 15 seconds, but the escape lottery probability may be changed. Specifically, in the lottery immediately after hitting the ball, a lottery is performed based on the escape lottery probability table in FIGS. 11 (A) and 11 (B) (escape lottery (2) -1, (2) -2). Therefore, in the case of not winning, in the lottery after 15 seconds, the lottery is performed based on the higher probability escape lottery probability table (FIGS. 13A and 13B). Hereinafter, the runaway lotteries performed based on the tables of FIGS. 13A and 13B are referred to as “runaway lottery (3) -1” and “runaway lottery (3) -2”.

  As described above, when the escape lottery (3) -1 and (3) -2 are performed in the stage moving process using the ball, the escape lottery (3) is substituted for the escape lottery (2) -2 in S45 of FIG. ) -2 (FIG. 13B), the escape lottery (3) -1 (FIG. 13A) is substituted for the escape lottery (2) -1 in S48. As a result, the escape lottery probability after 15 seconds can be changed to a higher probability than the escape lottery probability immediately after hitting the ball.

  FIG. 13 is a diagram illustrating an escape lottery probability table used for escape lottery (3) -1 and (3) -2 15 seconds after the ball is hit in the stage moving process using the ball. This table is set with a higher probability than the tables (2) -1 and (2) -2 (FIG. 11).

  (A) in the figure is an escape lottery probability table when there is a monster to be compared on the same stage (escape lottery (3) -1). The rank of the monster to be escaped and the rank of the monster to be compared Based on the above, the escape lottery probability is set.

  Escape lottery probability is 100% if the escaping monster is lower rank than the monster to be compared, 80% if the escaping monster is the same rank as the monster to be compared, and the escaping monster is the comparison target It is set to 50% in the case of higher rank than the monster.

  Figure (B) is the escape lottery probability table when there is no monster to be compared on the same stage (escape lottery (3) -2). The rank of the monster to be escaped and the rank of the monster to be compared Based on the above, the escape lottery probability is set.

  The escape lottery probability is set to 40% regardless of the rank of the escape monster if there is no monster to be compared.

  Thus, by changing the escape lottery probability after 15 seconds to 100% (or high probability), it is possible to set the monster to escape reliably (or with high probability) after 15 seconds. As a result, the effect of the ball is more powerful, and the player can turn around using the ecology of the monster.

  Conversely, if the escape lottery probability after 15 seconds is changed to a lower probability than the immediate escape lottery probability and the effect such as yellow smoke indicating that the ball has been hit is displayed lightly over time, You can express how the power of the ball fades and the effect of the monster running away fades away.

  In addition, in the stage movement process by the above-mentioned koji ball, the effect of the kneading ball is set as two lotteries in 15 seconds, but the time and the number of times are not limited to this. Moreover, you may enable it to extend the duration by hitting a koji ball once again while the effect of a koji ball lasts. Moreover, you may set so that an escape lottery probability may be raised, when a ball is applied a plurality of times, for example, the effect is doubled when the ball is applied continuously.

  Furthermore, although the game of the present embodiment can be played simultaneously by a plurality of people (for example, four people), it may be possible to hit the player character itself or other player characters with a ball. In this case, the player character may be able to rub the odor of the candy ball on his body by colliding with the monster.

  In the above embodiment, the “throwing of the koyashi ball” has been described as the “predetermined action” for changing the escape lottery probability, but the use of other items may be set as the “predetermined action”. The probability of run-off lottery may be changed by throwing a ball), holding a torch (burning pine tree), blowing a whistle, or attacking with a weapon.

  Also, in the escape lottery (1) performed in the normal stage movement process, the lottery is not performed at the same escape lottery probability (FIG. 8) every time a certain time (30 seconds) elapses. The escape lottery probability may be changed. Specifically, in the lottery after 30 seconds, the lottery is performed based on the escape lottery probability table in FIG. 8 (Escape lottery (1)). A lottery is performed based on a high probability escape lottery probability table (FIG. 14). Hereinafter, the escape lottery performed based on the table of FIG. 14 is referred to as “escape lottery (4)”.

  FIG. 14 is a diagram showing an escape lottery probability table used for the escape lottery (4) after 60 seconds (30 seconds + 30 seconds) in the stage moving process. This table is set with a higher probability than the table (1) (FIG. 8).

  In this table, escape lottery probabilities are set based on the ranks of escaping monsters and the ranks of monsters to be compared.

  The escape lottery probability is set to 100% when the escaping monster has a lower rank than the monster to be compared, and 50% when the escaping monster has the same rank as the monster to be compared. On the other hand, since the higher rank monster does not escape from the lower rank monster, the escape lottery probability is set to 0% when the escape monster is higher rank than the monster to be compared.

  In this way, by changing the escape lottery probability after 60 seconds (30 seconds + 30 seconds) to 100% (or high probability), the monster will surely escape (or with high probability) after 60 seconds. Can be set to As a result, even if there are two monsters on the same stage, at least one of the monsters reliably moves the stage in a short time, so that the power relationship between the monsters can be described more clearly.

  As described above, when the escape lottery (4) is performed in the stage moving process, the process of FIG. 15 is performed instead of the process of S16 to S18 of FIG. FIG. 15 shows a modification of the flowchart of FIG. According to this modification, after 60 seconds (30 seconds + 30 seconds), the escape lottery (4) is performed instead of the escape lottery (1), and the escape lottery probability after 60 seconds is changed to a high probability. Can do.

  In FIG. 15, first, when there is another monster in S15 of FIG. 10 (YES in S15), it is determined whether or not the staying time of the lottery target monster on the stage is 30 seconds (S30). When the staying time is 30 seconds (YES in S30), the escape lottery (1) (FIG. 8) is performed (S31). If a win is made (YES in S32), a destination stage lottery (S12) and a stage move (S13) are performed. If not won (NO in S32), the stage moving process is terminated.

  On the other hand, if the staying time is not 30 seconds (NO in S30), it is determined whether or not the staying time of the lottery target monster at that stage is 30 × m seconds (m is an integer of 2 or more) (S33). If the stay time is not 30 × m seconds (NO in S33), the stage moving process is terminated, but if the stay time is 30 × m seconds (YES in S33), the escape lottery (4) (FIG. 14) is performed. (S34). If a win is made (YES in S35), a destination stage lottery (S12) and a stage move (S13) are performed. If not won (NO in S35), the stage moving process is terminated.

  Note that the times shown in FIG. 7 and the probabilities shown in FIGS. 8, 9, 11, 13, and 14 are examples and can be changed as appropriate. In the above embodiment (escape lottery (1), (4)), the higher rank monster will not escape from the lower rank monster. Therefore, the escaping monster has a higher rank than the monster to be compared. In this case, the escape lottery probability is set to 0%. However, the escape lottery probability may be set so as to escape with a predetermined probability.

  Moreover, you may set so that a rank may reverse for a fixed time according to the condition of a game. For example, the ranks of monsters are reversed due to changes in weather or day and night, so that higher rank monsters can easily escape from lower rank monsters, and lower rank monsters do not escape from higher rank monsters. To. Specifically, it can be realized by replacing the monster on the side of each table and the monster to be compared.

  In the above embodiment, the run-off lottery probability is changed on condition that the player character performs “predetermined action”, but the initial setting of the game (difficulty level, etc.), the situation of the player character (physical strength, stamina, etc.) Etc.), the monster escape lottery probability and the lottery interval may be changed according to the progress of the game (quest remaining time, etc.). These can be realized by preparing a plurality of escape lottery probability tables in advance and changing the escape lottery probability table according to a predetermined condition (situation).

  For example, when the degree of difficulty is low, the escape lottery probability can be set high (using a high probability escape lottery probability table), or the lottery interval can be set short. Also, when the player character's physical strength and stamina are low, or when the remaining time of the quest is short, the escape lottery probability is set high according to the situation during the game (using the high probability escape lottery probability table) )can do.

  In addition, in order to control the competition of multiple monsters, the action to make a monster perform according to the relationship (rank, etc.) between monsters is to let one monster escape from the other monster and move to the other area (stage) It is not limited to the “escape action” to be moved, but may be an action that one monster can perform on the other monster. For example, it is only necessary to be able to express a state where there is no willingness to fight, such as standing still in the corner of the stage, or being excited.

  As described above, competitive control (escape lottery) is performed when there are a plurality of monsters in the same area (stage). When there are three or more monsters, the following processing is performed. For example, when three monsters are in the same area, the lottery is determined by the relationship between two of the three monsters (one of the other monsters).

For example, when there are monsters of ranks S, A, and B, “S does not escape (is difficult to escape) from A, but A escapes from S with a certain probability. (B) escapes with a predetermined probability with respect to A, but does not escape (is difficult to escape). Furthermore, S does not escape with respect to C (is difficult to escape), but C escapes with respect to S with a predetermined probability. Hereinafter, assuming that this relationship is described as “S>A> B using“> ””, the following lotteries (1) to (3) are performed.
(1) S draws lots based only on the relationship with A. (In the case of the lottery probability in FIG. 8: 0%)
(2) A draws based only on the relationship with S. (In the case of the lottery probability in FIG. 8: 40%)
(3) B draws based only on the relationship with S. (In the case of the lottery probability in FIG. 8: 40%)

  Thus, the monster with the highest rank in the same area performs a lottery based on the relationship with the monster of the rank (second) directly below. And the monsters of lower rank perform a lottery based on the relationship with the monster of the highest rank in the area. Thereby, even if it is a case where three or more monsters exist in the same area | region, the relationship between monsters can be expressed.

  In the lottery probability of FIG. 8, the probability does not change between (2) and (3). For example, if “(2) is set to 40%” and “(3) is set to 80%”, it corresponds to the rank. It is possible to express the relationship between the selected monsters more faithfully.

  In this embodiment, in order to control the competition of a plurality of monsters, the lottery probability is set based on the rank, which is one of the monster types. It is not limited to “S”, “Rank”, etc., and can be set according to the relationship (monster type) between other monsters. For example, there are the nature of the monster, the state of the monster, the correlation between the monsters (individual setting by natural enemies or pairs), and the like.

  First, the monster property is a property of a preset monster such as a herbivore, a carnivore, or a crustacean, and a predetermined probability is set based on the relationship between groups (including one) of the same property. For example, the probability is set based on the power relationship of carnivore> herbivore.

  Next, the monster state refers to the state of the monster that changes with the progress of the game, such as the amount of physical strength (remaining number), the battle state, or the normal state, and a predetermined probability based on the changed state. Set. For example, the probability is set based on a power relationship that a monster with a large number of remaining physical strength values> a monster with a small number of remaining physical strength values. This makes it possible to create a realistic expression that a weaker monster (with fewer remaining health values) is more likely to escape.

  Next, the correlation between monsters refers to a relationship between monsters such as “natural enemies” and “pairs” set in advance, and a predetermined probability is set based on the relationship. For example, for a monster that is in a natural enemy relationship, the lottery probability is set to a higher probability than the escape lottery (1) table (Fig. 8). The probability is set to a low probability compared to the escape lottery (1) table (FIG. 8).

  “Rank” means an absolute “order” (relationship of S> A> B> C) according to monster parameters (for example, combat ability, body size, etc.), but as described above ( The relationship between monsters (including one) can be provided with various pattern relationships including a “correlation” (a relationship of x> y, y> z, z> x) like Janken.

  In this embodiment, lottery is performed to control the competition based on the relationship between monsters on the condition that multiple monsters stay on the same “stage”, but limited to staying on the same “stage” It is only necessary to stay in the same “area”. An area that is a target of moving lottery such as these stages is referred to as a “moving lottery area”. Hereinafter, with reference to FIG. 16, an example of the movement lottery by “area” other than the stage will be described.

  First, with reference to FIG. 16A, an embodiment in which a predetermined coordinate area centered on a monster is a “moving lottery area” will be described. Instead of the entire stage as a moving lottery area as in the present embodiment, a moving lottery area is set in a predetermined area (movable coordinate area) centered on a certain monster, and other monsters stay in that area. When performing, a process (moving lottery) of leaving (moving) the area is performed.

  For example, when two monsters, an S rank monster 2 fighting against the player character 1 and a B rank monster 3 stay on stage 1 and are active, in the predetermined area 101 centered on the S rank monster 2 When the B rank monster 3 enters (for example, r1 = 30 m) and a predetermined time (for example, 10 seconds) elapses, a moving lottery is performed. Then, if the lottery is won, the B rank monster 3 moves out of the predetermined area 101 centered on the S rank monster 2.

  Specifically, a lottery is performed as to whether or not the B rank monster 3 goes out (moves) out of a predetermined area centered on the S rank monster 2 (escape lottery based on the relationship of S> B in FIG. 8 ( 1)), when the lottery is won, the lottery for which direction the predetermined distance (for example, r2 = 90 m) moves is performed, and it moves to the predetermined moving distance 103. Further, the distance r2 may be determined by lottery (where r2> r1).

  Conversely, the moving lottery may be similarly performed when the S rank monster 2 enters the predetermined area 102 centered on the B rank monster 3 and a predetermined time has elapsed.

  According to this, the B rank monster can be moved to a place where there is no sense of incongruity regardless of the topography of the stage or the position of the target S rank monster.

  Next, with reference to FIG. 16B, an example in which a predetermined fixed coordinate area in the stage is set as a “moving lottery area” will be described. As described above, the predetermined area centered on the monster is not set as the movement lottery area, but the stage is divided into areas 1 to 15 by a predetermined fixed coordinate area, and the fixed coordinate area is defined as the movement lottery area. To do.

  For example, when two monsters, S rank monster 2 fighting player character 1 and B rank monster 3 stay on stage 1 and are active, S rank in the same fixed coordinate area (for example, area 7) When the monster 2 and the B rank monster 3 stay and a predetermined time (for example, 10 seconds) elapses, a moving lottery is performed. Then, if the lottery is won, the B rank monster 3 draws a lot to which fixed coordinate area to move, and moves to the selected fixed coordinate area (for example, the area 9). Here, it is preferable that the destination area is an area (4, 5, 9, 10, 14, 15) that is not adjacent to the area 7.

  In the above-mentioned embodiment, if a plurality of monsters enter the same area, whether to move to another stage as in this embodiment or whether to leave a certain distance within the same stage Also good.

  Through the above process, monsters do not approach each other more than necessary within the same stage, and monsters that are inferior to other monsters are separated from the dominant monsters and are not in combat (only threatening or fighting Expresses the state of losing motivation).

  In addition, these embodiments also include fields that have no other stages (for example, only one stage in the field, or one stage that can inhabit monster ecology), a vast stage field, This is particularly effective in situations where there is no need to move one monster to the other stage even if the monster is on the same stage (for example, a correlation such as pairing or parent-child).
