Description

  The present invention relates to a game program and a game device, and more specifically, a game device and a game that change the display of an object appearing in a three-dimensional game space based on an operation of an input device that can specify an object in a predetermined screen. Regarding the program.

  Conventionally, various games have been developed that display an object displayed on a game screen in a zoomed-in manner. In such a game, for example, an object selected by a player from a plurality of objects displayed on the game screen is zoomed up and displayed. Specifically, a camera gazing point is set for the object, the camera viewpoint is switched, and the selected object is zoomed up (see, for example, Patent Document 1).

JP 2001-178963 A

  However, in the conventional technology as described above, since the player uses a cross key or a button to select an object to be zoomed in and displayed, an intuitive operation such as directly specifying an object can be performed. There wasn't.

  Therefore, an object of the present invention is to provide a game program and a game apparatus in which an object is designated intuitively and the designated object is zoomed up.

  The invention described in claim 1 is a game program executed by a computer of a game device having a display device (for example, the second LCD 12 if the corresponding relationship with the embodiment is shown) and an input device (15). The game program includes a first camera setting step (if the correspondence with the embodiment is shown, for example, step S11; hereinafter, only the step number is shown), a first display step (S12), and a position detection step (S23). ), A straight line calculating step (S24), an object specifying step (S25), a second camera setting step (S14), and a second display step (S12). The display device displays a game image in which a virtual three-dimensional game space in which an object appears is viewed from a virtual camera. The input device is a device for designating a position on the screen of the display device. In the first camera setting step, a parameter value of the virtual camera is set. In the first display step, the game image is displayed on the display device according to the parameters set in the first camera setting step. The position detection step detects a position on the screen designated by an operation performed on the input device when the game image is displayed in the first display step. In the straight line calculating step, a straight line passing through the position in the three-dimensional game space corresponding to the position detected in the position detecting step and the position of the virtual camera is calculated. The object specifying step specifies an object that intersects the straight line. In the second camera setting step, the value of the parameter of the virtual camera is changed so that the identified object is zoomed up and displayed. In the second display step, the game image is displayed on the display device in accordance with the parameter changed in the second camera setting step.

  According to a second aspect of the present invention, in the game program according to the first aspect, the computer further executes a region setting step (S11) for setting a predetermined region for each object. In the object specifying step, the object is specified when the area and the straight line intersect.

  According to a third aspect of the present invention, in the game program according to the second aspect, the region set in the region setting step is a sphere.

  According to a fourth aspect of the present invention, in the game program according to the second aspect, in the second camera setting step, the gaze point of the virtual camera is matched with a predetermined point of the identified object, and the angle of view of the virtual camera is specified. The value of the parameter of the virtual camera is changed by setting based on the area set in the object.

  According to a fifth aspect of the present invention, in the game program according to the first aspect, when the object is specified in the object specifying step, the instruction continuation time which is a time during which the instruction operation is continuously performed is a first predetermined value. The computer is further caused to execute a first condition determination step (S31) for determining whether or not the value exceeds. The second camera setting step changes the parameter value when it is determined in the first condition determination step that the first predetermined value is exceeded.

  According to a sixth aspect of the present invention, the game program according to the first aspect includes a second condition determining step (S41) and a third camera setting step (S42). The second condition determining step determines whether or not the instruction continuation time, which is the time during which the instruction operation is continuously performed, exceeds a second predetermined value when the object is specified in the object specifying step. In the third camera setting step, when it is determined in the second condition determining step that the second predetermined value has been exceeded, the parameter value of the virtual camera is returned to the value set in the first camera setting step. .

  According to a seventh aspect of the present invention, the game program according to the sixth aspect further includes an operation type determining step (S27), a parameter changing step (S28), and a second predetermined value setting step (S29). The operation type determination step determines the type of operation performed by the player based on the operation content of the player when the game image is displayed in the second display step. In the parameter changing step, the parameter value of the object is changed based on the operation type. In the second predetermined value setting step, a second predetermined value is set based on the parameter value changed in the parameter changing step.

  The invention described in claim 8 includes a display device (12), an input device (15), a first camera setting means (S11), a first display means (S12), and a position detection means (S23). A game apparatus having a straight line calculating means (S24), an object specifying means (S25), a second camera setting means (S14), and a second display means (S12). The display device displays a game image in which a virtual three-dimensional game space in which an object appears is viewed from a virtual camera. The input device is a device for designating a position on the screen of the display device. The first camera setting means sets the parameter value of the virtual camera. The first display means displays the game image on the display device in accordance with the parameters set by the first camera setting means. The position detecting means detects a position on the screen designated by an operation performed on the input device when the game image is displayed by the first display means. The straight line calculating means calculates a straight line passing through the position in the three-dimensional game space corresponding to the position detected by the position detecting means and the position of the virtual camera. The object specifying means specifies an object that intersects the straight line. The second camera setting means changes the value of the virtual camera parameter so that the identified object is zoomed up and displayed. The second display means displays the game image on the display device in accordance with the parameter after being changed by the second camera setting means.

  According to the first aspect of the invention, when the player performs an operation to instruct the object, the object is zoomed up and displayed, so that the player can easily grasp the operation target object and the player can operate the object. It can be made easier.

  According to the second and third aspects of the invention, since the object is specified using the predetermined area provided for each object, it is possible to reduce the processing load for specifying the object.

  According to the fourth aspect, when an area is set for each object and the object is zoomed, the angle of view of the camera is controlled based on the area of each object. Therefore, it is possible to zoom up the object with simpler processing than when calculating the size of the object each time the zoom is performed and calculating the angle of view of the camera. In addition, it is possible to easily set the angle of view of the camera for zooming up for each object.

  According to the fifth aspect, since the camera control is performed so that the object is zoomed up when the continuation time of the instruction operation has exceeded a predetermined time, the object is selected by mistake due to an erroneous operation not intended by the player. It is possible to prevent camera control based on the object. Further, since the camera control is not performed unless the player's object instruction operation continues for a predetermined time or more, the viewpoint does not frequently change, and the game performance can be improved.

  According to the sixth aspect of the present invention, after the camera is controlled so as to zoom in on the object, the camera control can be returned to the original after the duration of the operation of the player has exceeded a predetermined time.

  According to the seventh aspect, since the time until the camera control set to zoom up the object is returned based on the object parameters, the time for returning the camera control to each object is set. can do. Further, since the parameter value changes according to the operation type of the player, the time until the camera control is restored can be changed according to the operation content of the player.

  According to the eighth aspect, the same effect as in the first aspect described above can be obtained.

  FIG. 1 is an external view of a game device according to an embodiment of the present invention. In FIG. 1, the game apparatus 10 includes a first LCD (Liquid Crystal Display) 11 and a second LCD 12. The housing 13 includes an upper housing 13a and a lower housing 13b. The first LCD 11 is accommodated in the upper housing 13a, and the second LCD 12 is accommodated in the lower housing 13b. The resolutions of the first LCD 11 and the second LCD 12 are both 256 dots × 192 dots. In this embodiment, an LCD is used as the display device. However, any other display device such as a display device using EL (Electro Luminescence) can be used. An arbitrary resolution can be used.

  The upper housing 13a is formed with sound release holes 18a and 18b for releasing sound from a pair of speakers (30a and 30b in FIG. 2) to be described later.

  The lower housing 13b is provided with a cross switch 14a, start switch 14b, select switch 14c, A button 14d, B button 14e, X button 14f, Y button 14g, L button 14L and R button 14R as input devices. Yes. As a further input device, a touch panel 15 is mounted on the screen of the second LCD 12. The lower housing 13b is also provided with a power switch 19 and an insertion port for storing the memory card 17 and the stick 16.

  As the touch panel 15, an arbitrary system such as a resistive film system, an optical system (infrared system), and a capacitive coupling system can be used. The touch panel 15 has a function of outputting coordinate data corresponding to the contact position when the surface of the touch panel 15 is touched with the stick 16. In the following description, it is assumed that the player operates the touch panel 15 with the stick 16, but it is of course possible to operate the touch panel 15 with a pen (stylus pen) or a finger instead of the stick 16. In the present embodiment, the touch panel 15 having a resolution (detection accuracy) of 256 dots × 192 dots is used as in the resolution of the second LCD 12. However, the resolution of the touch panel 15 and the resolution of the second LCD 12 are not necessarily the same.

  The memory card 17 is a recording medium on which a game program is recorded, and is detachably attached to an insertion port provided in the lower housing 13b.

  Next, the internal configuration of the game apparatus 10 will be described with reference to FIG.

  In FIG. 2, a CPU core 21 is mounted on the electronic circuit board 20 accommodated in the housing 13. A connector 23 is connected to the CPU core 21 via a bus 22, an input / output interface circuit (referred to as I / F circuit in the drawing) 25, a first GPU (Graphics Processing Unit) 26, a second GPU 27, a RAM 24, and An LCD controller 31 is connected. The memory card 17 is detachably connected to the connector 23. The memory card 17 includes a ROM 17a that stores a game program and a RAM 17b that stores backup data in a rewritable manner. The game program stored in the ROM 17a of the memory card 17 is loaded into the RAM 24, and the game program loaded into the RAM 24 is executed by the CPU core 21. In addition to the game program, the RAM 24 stores temporary data obtained by the CPU core 21 executing the game program and data for generating a game image. The I / F circuit 25 is connected to the touch panel 15, the right speaker 30a, the left speaker 30b, and the operation switch unit 14 including the cross switch 14a and the A button 14d shown in FIG. The right speaker 30a and the left speaker 30b are respectively arranged inside the sound release holes 18a and 18b.

  A first VRAM (Video RAM) 28 is connected to the first GPU 26, and a second VRAM 29 is connected to the second GPU 27. In response to an instruction from the CPU core 21, the first GPU 26 generates a first game image based on data for generating a game image stored in the RAM 24, and draws the first game image in the first VRAM 28. Similarly, the second GPU 27 generates a second game image in accordance with an instruction from the CPU core 21 and draws it in the second VRAM 29. The first VRAM 28 and the second VRAM 29 are connected to the LCD controller 31.

  The LCD controller 31 includes a register 32. The register 32 stores a value of 0 or 1 according to an instruction from the CPU core 21. When the value of the register 32 is 0, the LCD controller 31 outputs the first game image drawn in the first VRAM 28 to the first LCD 11 and the second game image drawn in the second VRAM 29 as the second game image. Output to the LCD 12. When the value of the register 32 is 1, the first game image drawn in the first VRAM 28 is output to the second LCD 12, and the second game image drawn in the second VRAM 29 is output to the first LCD 11. To do.

  Note that the configuration of the game apparatus 10 as described above is merely an example, and the present invention can be applied to any computer system having at least one display device in which a touch panel is provided on a screen. In addition, the game program of the present invention may be supplied not only to the computer system through an external storage medium such as the memory card 17 but also to the computer system through a wired or wireless communication line. May be recorded in advance in the non-volatile storage device.

  Next, the outline of the game assumed in this embodiment will be described with reference to FIGS. 3 and 4. FIG. 3 is an example of a game screen assumed in this embodiment. In FIG. 3, objects (dogs that are virtual pets) 51 and 52 are displayed on the second LCD 12. This game is a game in which the player enjoys various reactions performed by the object when the player touches the object displayed on the screen with a stick or the like. In this game, when the player touches the object 51 or 52 with the stick 16 or the like, the object touched by the player is zoomed up as shown in FIG. The player performs operations such as “stroking” and “hitting” on the zoomed-up object using the stick 16 or the like, and enjoys the reaction of the object.

  Next, a game image generation process executed by the game apparatus 10 will be described with reference to FIGS. FIG. 5 is a flowchart showing the overall process of the game image generation process executed by the game apparatus 10. 7 is a subroutine showing the detailed operation of the operation process of FIG. 5, FIG. 9 is a subroutine showing the detailed operation of the object zoom process of FIG. 5, and FIG. 11 is a zoom release of FIG. It is a subroutine which shows the detailed operation | movement of a process.

  When the power of the game apparatus 10 is turned on, the CPU core 21 of the game apparatus 10 executes a startup program stored in a boot ROM (not shown), and each unit such as the RAM 24 is initialized. Then, the game program and various data stored in the memory card 17 are read into the RAM 24 via the connector 23, and the execution of the game program is started.

  In FIG. 5, first, a game initial setting process is performed (step S11). The processing in step S11 will be described more specifically. The CPU core 21 appropriately arranges an image such as an object to be displayed and a background in the three-dimensional space. Next, a radius value is set for each object displayed on the screen. The radius value is used to determine the angle of view of the virtual camera set in the three-dimensional game space in the object zoom processing described later. Further, a hit determination range is set for each object. The hit determination range is set in a spherical shape in the three-dimensional space, and is used for determining an object to be zoomed up (hereinafter, the hit determination range is referred to as a hit determination ball). In addition, a first setting value used as a threshold value is set in an object zoom process or the like described later. The first set value is a threshold value for determining whether or not the player continues to touch the touch panel 15 for a predetermined time or more. For example, when the value “3 seconds” is set as the first setting value, the object is not zoomed unless the user continues to touch the object for 3 seconds or more (details will be described later). Next, the parameters of the virtual camera are set to initial values. The parameters include the position of the virtual camera, the angle of view, and the gaze point. The initial value is set in advance so that all objects displayed on the screen can be accommodated on the screen.

  When the initial setting process as described above is completed, the CPU core 21 displays an image viewed from the virtual camera on the second LCD 12 (step S12). Specifically, the modeling coordinate system, which is the coordinate data of the polygons forming each object, is converted into a viewpoint coordinate system with the virtual camera as the origin. Then, the projection conversion is performed by calculating the effects such as perspective and the part hidden behind the front object. Finally, it is converted into a screen coordinate system that matches the displayed screen and displayed on the second LCD 12.

  FIG. 6 is a diagram showing the relationship between the camera after the initial setting in step S11 and the three-dimensional space. When an image is drawn by the process of step S12 in the three-dimensional space in the initial setting state, as shown in FIG. 3, the objects 51 and 52 are displayed so as to fit within the screen. When the process of step S12 ends, the CPU core 21 advances the process to the next step S13.

  FIG. 7 is a flowchart showing details of the operation process shown in step S13. In FIG. 7, first, the CPU core 21 determines whether or not an input operation (hereinafter referred to as a touch operation) by the touch panel 15 has been performed (step S21). If no touch operation is performed as a result of the determination (NO in step S21), the operation process is terminated. On the other hand, if a touch operation has been performed (YES in step S21), the process proceeds to the next step S22. In step S22, it is determined whether or not a zoom-up flag indicating whether or not the object is currently zoomed up is ON. If the result of determination in step S22 is that the zoom-up flag is ON (YES in step S22), the process proceeds to step S27 described later. On the other hand, when the zoom-up flag is OFF (NO in step S22), the process proceeds to the next step S23. In step S23, the input coordinate value (X, Y) on the touch panel 15 is detected.

  Next, the CPU core 21 calculates a straight line (hereinafter referred to as a determination straight line) that passes through the virtual camera position and the coordinates in the three-dimensional space (hereinafter referred to as user-specified coordinates) corresponding to the input coordinate values on the touch panel 15. (Step S24). Hereinafter, the process of step S24 will be described more specifically. Note that, in the three-dimensional space, the Z axis of the world coordinate system is taken in a direction perpendicular to the projection plane. The X axis corresponds to the horizontal direction of the projection plane, and the Y axis corresponds to the vertical direction of the projection plane. The three-dimensional space in this embodiment will be described below assuming that it has such a coordinate system.

First, the coordinate values (x, y) on the touch panel 15 are converted into user-specified coordinates (X, Y, Z) using the following formula.
X = camX + (dXY × x)
Y = camY + (dXY × y)
Z = camZ + dZ
In the above formula, camX, camY, and camZ indicate the coordinates of the virtual camera in the three-dimensional space. dXY is a variable used for converting the input coordinate value of the touch panel 15 into a coordinate value in a three-dimensional space. dZ indicates the distance from the virtual camera to the projection plane. The variable dXY can be obtained by the following equation based on dZ and the tangent (tan) of the angle of view θ of the virtual camera.
dXY = dZ × tan θ
If the user-specified coordinates can be calculated, a determination straight line that passes through the position of the virtual camera and the user-specified coordinates is calculated.

  Next, the CPU core 21 performs a process of specifying the object designated by the player (step S25). Specifically, it is determined whether or not any of the hit determination balls set for any object in the three-dimensional space intersects the determination line. As a result of the determination, if the determination straight line does not intersect with any hit determination ball (NO in step S25), it is determined that no object is instructed, and the operation process is terminated. On the other hand, if the determination straight line intersects any one of the hit determination balls (YES in step S25), the player indicates an object having the hit determination ball. At this time, counting of the time during which the player keeps touching the touch panel 15, that is, the time during which the player continues to indicate an object (hereinafter referred to as duration) is started (step S26). Taking the case of FIG. 8 as an example, the determination straight line hits the hit determination ball of the object 51 (the head of the dog character). Therefore, the player indicates the object 51, and the time that the player continues to touch the touch panel 15 starts to be counted.

  Next, the operation type is determined (step S27). The operation type includes, for example, a “stroking” operation in which the stick 16 is moved while being in contact with the touch panel 15, and a “tapping” operation in which an operation in which the stick 16 is brought into contact with and released from the touch panel 15 is repeated in a short time. Conceivable. As an operation type determination method, for example, the following method can be considered. First, the input history of the stick 16 after zooming in is recorded. Next, the contact state of the stick 16 and the change of the input coordinate value are detected from the input history. Then, if the contact state is kept in contact for a long time and the input coordinate value changes within a predetermined range, it is determined that the operation is “stroking”. The predetermined range is, for example, a range obtained by converting the coordinates of the hit determination sphere of the object designated by the player into two-dimensional coordinates on the touch panel 15. If contact / non-contact is repeated and the input coordinate value is within the predetermined range, it is determined that the operation is “tapping”. With the method described above, it is possible to determine what action the player is taking with respect to the object that is a virtual pet (dog).

  Next, the CPU core 21 changes the parameters set specifically for the object based on the operation type determined in step S27 (step S28). In the present embodiment, a parameter “degree of familiarity” is set for an object that is a virtual pet (dog). In step S28, when the operation type described above is “stroking”, the “degree of nagging” is increased, and when it is “tap”, the value of “naching level” is decreased.

  Next, a second set value is set based on the parameter (step S29). The second set value is used as a value indicating a zoom-up release timing of a zoom process described later. For example, when the “degree of familiarity” is less than a predetermined value (when not very well), the second set value is set to 5 seconds, and when the “degree of familiarity” is equal to or greater than a predetermined value (when well-acquainted) Sets the second set value to 10 seconds. If the second set value is set in step S29, the CPU core 21 ends the operation process and proceeds to the object zoom process (step S14) in FIG.

  FIG. 9 is a flowchart showing details of the object zoom process shown in step S14 in FIG. In FIG. 9, first, the CPU core 21 determines whether or not the duration has exceeded the first set value (that is, whether or not the player has kept touching the touch panel 15 for a predetermined time or more) (step S31). If the result of this determination is that the first set value is not exceeded (NO in step S31), the object zoom process is terminated.

  On the other hand, if it exceeds the first set value (YES in step S31), the CPU core 21 determines whether or not the duration has exceeded the second set value (step S32). As a result of the determination, if the second set value is exceeded (YES in step S32), the object zoom process is terminated. On the other hand, if the second set value is not exceeded (YES in step S32), the process proceeds to the next step S33.

  In step S33, the CPU core 21 sets a predetermined point (for example, the center point of the target object) on an object (hereinafter referred to as a target object) in contact with the determination straight line as a gazing point. Then, the CPU core 21 advances the processing to the next step S34.

  In step S34, the CPU core 21 changes the angle of view of the virtual camera based on the radius value set for the target object. At the same time, the zoom-up flag is set to ON. Specifically, taking FIG. 10 as an example, first, the center of the target object 51 is set as a gazing point. Then, the angle of view (that is, the object 51 is zoomed in so that the diameter of the sphere having the radius set in the object 51 with the gazing point as the center point coincides with the vertical size of the screen). Set the angle of view) to the virtual camera. After step S34, when the process of step S12 (screen drawing process) is performed, a screen with the object zoomed up as shown in FIG. 4 is displayed.

  When the process of step S34 is completed, the CPU core 21 ends the object zoom process and proceeds to the zoom release process (step S15) of FIG. In the zoom canceling process in step S15, even if the player performs some operation during zooming up, if the time set in the second set value elapses, the zoomed up display (see FIG. 4) is restored to the original display (see FIG. 4). The process of returning to (see FIG. 3) is performed. Also, when the player does not perform an operation for a predetermined time or more after zooming up, a process for returning the zoomed-up display to the original display is performed in the same manner.

  FIG. 11 is a flowchart showing details of the zoom cancellation processing shown in step S15. In FIG. 11, first, the CPU core 21 determines whether or not the duration has exceeded the second set value (step S41). As a result of the determination, if the second set value is exceeded (YES in step S41), the virtual camera setting is set to the initial value. At the same time, the counting of the duration time started in step S26 is stopped (step S42). This is the case, for example, when the second set value is set to 10 seconds and the object that is a virtual pet (dog) is kept stroked for 10 seconds or more during zooming. On the other hand, when the second set value is not exceeded (NO in step S41), the process proceeds to step S43.

  In step S43, it is determined whether or not there has been a touch operation on the object within a predetermined time. That is, after zooming up the object, it is determined whether or not any touch operation is performed on the object within the second set value, for example, within 10 seconds. If the result of this determination is that there is a touch operation within a predetermined time (YES in step S43), the player is in the middle of performing some touch operation on the object, so the camera settings remain unchanged (zoom The zoom canceling process is terminated. On the other hand, when the touch operation is not performed within the predetermined time (NO in step S43), the CPU core 21 advances the process to step S42 described above. That is, when the object (dog) is zoomed up and left without touching, the camera setting returns to the initial value after a predetermined time, for example, 5 seconds, and the zoom-up is canceled. Thus, the zoom cancellation process ends.

  Returning to FIG. 5, when the zoom canceling process in step S15 is completed, it is next determined whether or not a predetermined game end condition is satisfied (step S16). If the predetermined game end condition is not satisfied (NO in step S16), the process returns to step S12, and the operations in steps S12 to S16 are repeated until the game end condition is satisfied. On the other hand, if the game end condition is satisfied (YES in step S16), a predetermined game over process (such as a process for selecting whether or not to continue the game) is performed, and the game is ended. This is the end of the game image generation process according to the present embodiment.

  As described above, the game program of the present invention can zoom up and display the touched object when the player touches the object displayed on the screen via the touch panel. For this reason, it is possible to easily perform an operation on the object.

  Whether or not the object is touched is determined by whether or not the determination straight line in the three-dimensional space and the hit determination ball intersect. Here, as a method of determining whether or not the player is pointing to an object, there is a method of determining on a two-dimensional coordinate. In this method, first, each object in the three-dimensional space is converted into two-dimensional coordinates. Then, it is determined whether or not the input coordinates of the player are within the hit determination range set for each object. Therefore, when the number of objects is large, the number of processes for converting to two-dimensional coordinates increases. Furthermore, in order to convert from three-dimensional coordinates to two-dimensional coordinates, it is necessary to perform many calculations, and the load of the conversion process itself is high. On the other hand, according to the present invention, as long as the input coordinates on the touch panel of the player are converted into the coordinates in the three-dimensional space, it is only necessary to determine whether or not the straight line and the sphere intersect. Therefore, the processing load can be reduced as compared with the processing for determination on the above two-dimensional coordinates.

  In addition, since zoom-up control is performed based on the radius value set for each object, it is easier to calculate the angle of view of the camera by calculating the size of the object each time you zoom up. The object can be zoomed up in the process.

  Further, the time when the player is touching the touch panel is measured, and the timing for zooming up the object is adjusted. Accordingly, it is possible to prevent unnecessary zoom processing due to an erroneous operation by the player, such as the object being zoomed up by touching it by mistake. That is, when an operation using the touch panel is performed, since the entire display screen is generally operated, an operation error of the player, an erroneous detection of touch panel coordinates, and the like are likely to occur compared to a normal button operation. Therefore, in a game or the like operated using a touch panel, when the camera movement technique as described in Patent Document 1 described above is used, when an object that is not intended by the player is selected due to an operation error or erroneous detection, the zoom up is performed each time. Done. As a result, the viewpoint changes frequently, and the game performance becomes very poor. Therefore, in the present invention, the time during which the player is touching the touch panel is measured, and the timing for zooming up the object is adjusted.

  Further, after the zoom-in display of the object, the camera control can be returned to the original after the operation duration time has elapsed for a predetermined time or more. Further, since the predetermined time is set based on the parameters of each object, it is possible to set a time for returning the camera control to each object. Further, since the parameter value changes according to the instruction state of the object, the time until the camera control is restored can be changed according to the operation content of the player.

  The virtual camera position, angle of view, and gazing point are used as the virtual camera parameters in the above-described embodiment. However, the present invention is not limited to this, and the parameters can be zoomed up by changing the values. Anything is fine.

  Moreover, although the touch panel is used in the above-described embodiment, a mode in which the player indicates an object using a mouse instead of the touch panel may be used.

  A game program and a game device according to the present invention can zoom-in display when a player touches an object displayed on a screen, and controls a camera in conjunction with an operation using a touch panel. Useful for applications.
