Description

  The present invention relates to a game program and a game system for a game set in a three-dimensional virtual game space.

  2. Description of the Related Art Conventionally, there is a game that progresses with a player character acting in a virtual game space by a user operation. For example, there is a gun shooting game in which a user operates a player character having a firearm such as a gun or a rifle, and advances the game while shooting and defeating an enemy character encountered (for example, Patent Document 1).

  In the game described in Patent Document 1, a player character and an enemy character are arranged in a three-dimensional virtual space. The video to be displayed on the display can be selected from two images: a video from the viewpoint of the player character (first-person viewpoint) and a video from the viewpoint of viewing both the player character and the enemy character (third-person viewpoint). Among these, in the first person viewpoint, the virtual game space viewed from the player character and the appearance of the enemy character are directly displayed on the display. Therefore, the user can play the game as if he / she is in the virtual space together with the player character.

JP2008-93307

  By the way, when displaying an image of the first person viewpoint on the display, there is a problem that it is difficult to grasp the sense of distance in the depth direction. For example, the enemy character may be positioned in the depth direction of the display with respect to the player character. In such a case, it is difficult to grasp the distance from the player character to the enemy character, and it is difficult to determine whether an attack (for example, an attack with a throwing-type weapon) reaches the enemy character.

  Accordingly, an object of the present invention is to provide a game program and a game system that realize a game that is played in a three-dimensional virtual game space, and in particular a game in which a user can easily grasp the distance in the depth direction.

  The game program according to the present invention includes a computer, virtual space generation means for generating a three-dimensional virtual game space, and game image generation for generating a two-dimensional game image based on an image obtained by photographing the virtual game space with a virtual camera. Means, a first operation acquisition means for acquiring a physical and continuous displacement amount of the first operation section operated by the user, a second operation acquisition means for acquiring an operation to the second operation section by the user, and a game A game progress control means for controlling the progress, wherein the game image generating means displays a target mark indicating a position in the depth direction to which the virtual camera is directed on the game image, and the first operation The game progress control means moves the position of the target mark along the depth direction according to a continuous change in the displacement amount of the part, and the game progress control means controls the second operation part. Depending on, to exert a predetermined effect associated with the position of the target mark during the operation.

  Thereby, in the three-dimensional virtual game space, it becomes easy to grasp the distance in the depth direction from the position of the virtual camera (that is, the depth direction between the virtual camera or the player character and the target). Therefore, even when the virtual game space is viewed from the first person viewpoint that matches the viewpoint of the player character, the distance to the target existing in the depth direction can be accurately grasped. In addition, the content of the predetermined effect exhibited according to the operation on the second operation unit is not particularly limited. For example, the “predetermined effect” includes that the attack hits the target mark position by the operation of the second operation unit, and that the player character jumps to the target mark position.

  Further, the game image generation means may display a gauge indicating the distance in the depth direction on the game image together with the target mark.

  Thereby, the user can grasp | ascertain the direction and distance which a target mark can move.

  Further, the direction of the distance indicated by the gauge may change in the left and right and up and down directions of the virtual game space in accordance with a change in the orientation of the virtual camera.

  Accordingly, the left and right and up and down directions can be specified by the orientation of the virtual camera, and the depth direction can be specified according to the amount of displacement of the first operation unit. Therefore, not only the position on the surface of the object such as the ground and the wall surface but also an arbitrary position in a space away from the object can be specified by the target mark.

  The game image generation means may display the target mark so that it is larger as the position is closer and smaller as it is farther away.

  Thereby, it becomes easy to grasp the perspective of the depth position of the target mark.

  Further, the position of the target mark and the content of the effect related to the position may be associated with each other.

  For example, the position of the target mark may be associated with the content of the attack to be advanced to that position. More specifically, when the target mark is close to the player character, the action or weapon of the player character suitable for attacking the enemy character at a short distance is automatically set. When the target mark is far from the player character, the player character's motion or weapon suitable for attacking the enemy character at a long distance is automatically set. In this way, it is possible to automatically set an appropriate attack content according to the position of the target mark.

  The first operation unit may include an operation element that is biased in a predetermined direction.

  Accordingly, the target mark can be adjusted to a position desired by the user by an intuitive operation that can be performed in a very short time of displacing the operation element.

  In addition, a game system according to the present invention includes a program storage unit that stores any of the above-described game programs, and a computer that executes the program stored in the program storage unit.

  According to the present invention, it is possible to provide a game program and a game system for realizing a game that is played in a three-dimensional virtual game space, and in particular, a game in which the user can easily grasp the distance (distance) in the depth direction. .

  The disk drive 12 can be loaded with a disk type recording medium 30 such as a DVD-ROM. On the disc-type recording medium 30, a game program 30a and game data 30b according to the present embodiment are recorded. The game data 30b includes various data necessary for the progress of the game, such as data necessary for forming each character and virtual game space. In addition, a card-type recording medium 31 can be loaded in the memory card slot 13, and save data indicating a play status such as a game progress can be recorded in accordance with an instruction from the CPU 10.

  The HDD 14 is a large-capacity recording medium built in the game apparatus 2 and records a game program 30a and game data 30b read from the disk-type recording medium 30, and save data and the like. The ROM 15 is a semiconductor memory such as a mask ROM or PROM, and stores a startup program for starting the game apparatus 2, a program for controlling an operation when the disk type recording medium 30 is loaded, and the like. The RAM 16 is composed of DRAM, SRAM, or the like, and reads a game program 30a to be executed by the CPU 10 or game data 30b necessary for the execution from the disk-type recording medium 30 or the HDD 14 in accordance with the game play status. To record temporarily.

  Further, a graphic processing unit 17, an audio synthesis unit 20, a wireless communication control unit 23, and a network interface 26 are connected to the CPU 10 via the bus 11.

  Among these, the graphic processing unit 17 draws a game image including the virtual game space, each character, and the like in accordance with an instruction from the CPU 10. That is, the position, orientation, zoom rate (view angle), etc. of the virtual camera set in the virtual game space are adjusted to shoot the virtual game space. Then, the photographed image is rendered, and a two-dimensional game image for display is generated. In addition, an external display (display unit) 19 is connected to the graphic processing unit 17 via a video conversion unit 18. The game image drawn by the graphic processing unit 17 is converted into a moving image format by the video conversion unit 18 and displayed on the display 19.

  The audio synthesizing unit 20 reproduces and synthesizes digital game sound in accordance with instructions from the CPU 10. An external speaker 22 is connected to the audio synthesis unit 20 via an audio conversion unit 21. Accordingly, the game sound reproduced and synthesized by the audio synthesizing unit 20 is decoded into an analog format by the audio converting unit 21 and outputted from the speaker 22 to the outside.

  The wireless communication control unit 23 has a 2.4 GHz band wireless communication module and is wirelessly connected to the controller 24 attached to the game apparatus 2 so that data can be transmitted and received. The user can input a signal to the game apparatus 2 by operating the operation unit 25 (see FIG. 2) such as a button provided on the controller 24, and can perform the action of the player character displayed on the display 19. Control.

  FIG. 2 is a diagram for explaining the configuration of the controller 24. The controller 24 includes a plurality of operation units 25 (251 to 253) in addition to the communication unit 24a that communicates with the wireless communication control unit 23. Specifically, the operation unit 25 includes a volume switch type first operation unit 251, an on / off type second operation unit 252 and a stick type third operation unit 253.

  The volume switch type first operation unit 251 is configured to be physically and continuously displaced by a user operation. The operation amount by the user (physical displacement amount of the first operation unit 251) and the output signal value (for example, voltage value or frequency) have a one-to-one relationship. Typically, as shown in the graph of FIG. 2, the operation amount of the first operation unit 251 and the output signal value are in a proportional relationship. Therefore, the CPU 10 can uniquely acquire the operation amount of the first operation unit 251 by the user based on the output signal from the first operation unit 251. As will be described in detail later, in the game system 1, a target mark is displayed in the game image in order to make it easier to grasp the depth direction position (space) where the virtual camera is pointed. The display position of the target mark in the depth direction of the virtual game space changes according to the continuous change in the displacement amount of the first operation unit 251.

  As a specific configuration example of the first operation unit 251, as shown in FIG. 2, an operation element 251 a urged in the protruding direction by an elastic body or the like, and a linear displacement sensor that detects a displacement amount of the operation element 251 a And can be adopted. In the case of such a configuration, when the operating element 251a in the protruding state (non-operating position) is operated so as to be pressed with, for example, an index finger, it can be pushed down to a predetermined position (maximum operating position). Further, when the pushing pressure of the index finger is eased, the operation element 251a returns to the initial state by the urging force. The first operation unit 251 then moves from the non-operation position at an arbitrary position (displacement amount; x%) between the non-operation position (displacement amount; 0%) and the maximum operation position (displacement amount; 100%). The output signal value corresponding to the displacement amount (operation amount) of the operation element 251a is output.

  The on / off-type second operation unit 252 includes a button-like operation element 252a operated with, for example, a user's thumb. The second operation unit 252 outputs an on signal when operated by the user, and outputs an off signal when not operated (or does not output an on signal). The second operation unit 252 is used, for example, for determination of various setting items on the configuration screen, execution (determination) of a predetermined action of the player character such as an attack on an enemy character or a jump.

  The stick-type third operation unit 253 includes, for example, a stick-like operation element 253a that is operated with the user's thumb. The operation element 253a can be tilted to 360 ° in all directions centering on the reference position in the upright state. When the third operation unit 253 is operated, for example, the player character moves or the shooting target mark displayed in the virtual game space moves according to the tilt direction. Alternatively, the orientation of the virtual camera that captures the virtual game space is changed. For example, if the operation element 253a of the third operation unit 253 is tilted in the left-right direction, the virtual camera is also turned in the left-right direction, and if the operation element 253a is tilted in the front-rear direction (vertical direction), the virtual camera is also turned in the vertical direction. To do.

  Note that the number of operation units 251 to 253 of each type is not limited to one, and a plurality of each may be provided. In addition, the configuration of each of the operation units 251 to 253 described above is an example, and the specific configuration is not limited to this, and other configurations can be adopted as appropriate.

  Returning to the description of FIG. 1, the network interface 26 connects the game apparatus 2 to a communication network NW such as the Internet or a LAN, and can communicate with other game apparatuses 2 and the server apparatus 3. . Then, by connecting the game apparatus 2 to another game apparatus 2 via the communication network NW and transmitting / receiving data to / from each other, a plurality of player characters can be displayed in synchronization within the same game space. Therefore, multiplayer in which a plurality of people advance the game together is possible.

(Functional configuration of game device)
FIG. 3 is a block diagram illustrating a functional configuration of the game apparatus 2 included in the game system 1. The game device 2 executes the game program of the present invention, so that a game space generation unit 40, a character control unit 41, a game image generation unit 42, a camera control unit 43, an operation acquisition unit 44, and a game progress control unit 45 Function. Each of these functions is composed of the CPU 10, HDD 14, ROM 15, RAM 16, graphic processing unit 17, video conversion unit 18 and the like shown in FIG.

  The game space generation unit 40 generates a three-dimensional virtual game space as a stage where the player character acts. For example, the virtual game space is generated by determining the position and texture of the object, determining the light source setting, determining the effect settings such as fog and sparks, etc., for each elapse of one frame according to the frame rate. .

  The character control unit 41 generates, in the virtual game space, a player character for which the user operates an action and a non-player character that cannot be operated by the user. Further, the movement of the player character is controlled according to the operation of the operation unit 25 by the user, or the movement of the non-player character is controlled according to the game situation. For example, when the user depresses the second operation unit 252, the player character is caused to perform a predetermined action such as a jump action, a throwing action of a weapon such as a grenade or a knife. When the user tilts the third operation unit 253 in a certain direction, the posture or line of sight of the player character is changed in that direction, or the player character is moved in that direction.

  The game image generation unit 42 generates a game image to be displayed on the display 19 at a predetermined frame rate based on the image taken by the virtual camera. For example, based on the virtual game space generated by the game space generation unit 40, a rendering process is performed in order to obtain a two-dimensional game image captured by a virtual camera. In this rendering processing, known image processing such as solid processing, extraction processing, transparency processing, effect processing, and screen processing is appropriately performed as necessary. Further, the above-described target mark displayed as a guide for the position in the depth direction is displayed so as to be superimposed on the two-dimensional image in the virtual game space by the above-described screen processing.

  FIG. 4 is a diagram illustrating an example of a game image on which a target mark is displayed. As shown in FIG. 4, the game image 50 represents a three-dimensional virtual game space in two dimensions, and a gauge 51 and a target mark 52 are displayed therein. The gauge 51 displays the distance in the depth direction from the virtual camera at equal intervals, and is constituted by a scale line 53 and a scale number 54 in the example of FIG.

  More specifically, a plurality of scale lines 53 are displayed at equal intervals from the position of the virtual camera in the depth direction, and scale numbers 54 are attached to the scale lines 53. The scale line 53 includes a vertical scale line 53a in the vertical direction (vertical direction) and a horizontal scale line 53b in the horizontal direction (horizontal direction). The vertical scale line 53a is displayed on one side of the game image. The horizontal scale line 53b is displayed below the game image. Further, the scale lines 53a and 53b are both longer in dimension and shorter in distance, and express a perspective according to the one-point perspective method.

  In the game image 50, a target mark 52 is displayed together with such a gauge 51. In the example of FIG. 4, the target mark 52 is represented by a symbol that combines a circle and a cross, and is displayed in the approximate center of the game image. A scale line 53 (or scale number 54) corresponding to the position of the target mark 52 in the depth direction is highlighted. Specifically, the corresponding scale line 53 has a different color from the other scale lines 53, is thicker than others, or has a different line type. By referring to the gauge 51 and the target mark 52 as described above, the user can easily grasp the distance (distance) in the depth direction to the target mark 52.

  In addition, the structure of the gauge 51 and the target mark 52 is not limited to the aspect illustrated above. Speaking of the gauge 51, the scale line 53 may omit either the vertical scale line 53a or the horizontal scale line 53b, or may omit either the scale line 53 or the scale number 54. Good. Further, if the position of the target mark 52 in the depth direction can be grasped, the highlighting of the scale line 53 or the like is not essential. Further, if the position of the target mark 52 in the depth direction is expressed by displaying the “shadow” of the target mark 52 on the object corresponding to the position of the target mark 52 in the depth direction, the gauge 51 may be omitted. it can. Furthermore, the size of the target mark 52 may be made larger as it is closer and smaller as it is farther away, so that the position in the depth direction can be easily grasped. In short, it is only necessary that the user who viewed the game image can grasp where the target mark 52 is located in the depth direction of the virtual game space.

  The camera control unit 43 controls a virtual camera that captures the virtual game space. For example, when the user tilts the third operation unit 253 in a certain direction, the direction of the virtual camera is changed in that direction. Further, when the orientation of the virtual camera is changed, the direction of the distance indicated by the gauge 51 described above is also changed. That is, the display position in the game image of the gauge 51 is substantially fixed, and the direction of the distance indicated by the gauge 51 changes to the left and right and up and down when the orientation of the virtual camera changes to the left and right and up and down.

  The operation acquisition unit 44 includes a first operation acquisition unit 44a, a second operation acquisition unit 44b, and a third operation acquisition unit 44c, and acquires the presence / absence of an operation on each operation unit 25 by the user and the operation amount. That is, the first operation acquisition unit 44a acquires the operation amount (physical displacement amount) by the user for the volume switch type first operation unit 251. The second operation acquisition unit 44b acquires the presence / absence of a pressing operation for the on / off-type second operation unit 252. The third operation acquisition unit 44c acquires the presence / absence of the stick tilting operation and the tilting direction of the stick-type third operation unit 253.

  In the game, when the first operation acquisition unit 44a acquires the displacement amount of the first operation unit 251, the game image generation unit 42 displays the gauge 51 and the target mark 52 on the game image 50. Further, the display position of the target mark 52 is changed along the depth direction in accordance with the change in the displacement amount of the first operation unit 251. For example, when the displacement amount of the first operation unit 251 is small, the target mark 52 is displayed at a position close to the virtual camera, and the target mark 52 is displayed at a far position in the depth direction as the displacement amount is large. Further, along with the movement of the target mark 52, the scale line 53 (or the scale number 54) emphasized in the gauge 51 also changes.

  The game progress control unit 45 controls the progress of the game in accordance with the user's operation and the passage of time in the game. For example, when the user depresses the second operation unit 252, an attack is made against the enemy character existing at the target mark 52 at that time, or the player character jumps to the position of the target mark 52. . Alternatively, the environment (weather, day and night, season, etc.) in the virtual game space is changed with the passage of time in the game. Further, enemy characters appear at various locations in the virtual game space in accordance with the location of the player character.

(Game system operation)
Next, the operation of the game system according to the operation of the controller 24 by the user will be described. Here, an operation related to the alignment of the target mark 52 by the operation of the first operation unit 251 (hereinafter referred to as “target mark alignment operation”) and the effect related to the target mark position by the operation of the second operation unit 252. The operation (hereinafter referred to as “effect activation operation”) will be described.

[Target mark alignment operation]
FIG. 5A is a flowchart showing the control contents during the target mark alignment operation of the game system 1, and FIG. 5B is a schematic diagram showing the game image 50 during the target mark alignment operation. As shown in FIG. 5A, the game system 1 determines whether or not the first operation unit 251 has been operated by the user (step S10). If not operated (step S10: NO), the gauge 51 and the target mark 52 are not displayed on the game image ("non-operation" in FIG. 5B). On the other hand, when operated (step S10: YES), the position of the target mark 52 in the depth direction is continuously changed in accordance with the continuous change in the displacement amount of the first operation unit 251 (step S11). .

  More specifically, in this game, a range in which the first operation unit 251 is physically and continuously displaced is associated with a range in which the display position of the target mark 52 is continuously changed. A unique display position is assigned to an arbitrary displacement amount of the first operation unit 251. Specifically, the display position of the target mark 52 is set to be farther as the displacement amount of the first operation unit 251 increases. Accordingly, in step S11, the display position of the target mark 52 is set closer as the displacement amount of the first operation unit 251 is smaller, and the display position is moved further as the displacement amount is larger. Further, the target mark 52 is displayed so that it is larger as the position is closer and smaller as it is farther so that the perspective of the target mark 52 at this time can be easily grasped. Further, along with the movement of the target mark 52, the scale line 53 (or the scale number 54) of the gauge 51 is highlighted corresponding to the position of the target mark 52.

  Thereby, the user can grasp the distance in the depth direction with reference to the target mark 52 and can easily grasp the time until the target in the virtual game space. Further, by operating the third operation unit 253 in addition to the first operation unit 251, the display position of the target mark 52 can be adjusted in the left and right and vertical directions in addition to the depth direction. Therefore, the target mark 52 can be aligned with an arbitrary position in the three-dimensional virtual game space. Further, since the physical displacement amount of the first operation unit 251 and the display position of the target mark 52 are associated with each other, the user can quickly target the position of the target mark 52 by operating the first operation unit 251. Can be matched.

[Effect activation operation]
FIG. 6 is a flowchart showing the control contents during the effect activation operation of the game system 1. The game system 1 executes the operation shown in FIG. 6 independently of the operation shown in FIG. As shown in FIG. 6, the game system 1 determines whether or not the on / off-type second operation unit 252 has been operated by the user (step S20). If it has not been operated (step S20: NO), the current state is maintained, and if it is determined that it has been operated (step S20: YES), the position of the target mark 52 at that time is acquired (step S21). That is, when the user operates the second operation unit 252 while operating the first operation unit 251, the position of the target mark 52 according to the amount of displacement of the first operation unit 251 at the time of operation of the second operation unit 252. To get.

  Next, based on the position of the target mark 52 acquired in step S21, a predetermined effect related to this position is activated (step S22). For example, the player character in the vicinity of the virtual camera is moved to the position of the target mark 52, and an attack is applied to the enemy character at the destination. At this time, the virtual camera may be moved together with the player character, or only the player character may be moved while maintaining the current position of the virtual camera. When only the player character is moved, the virtual camera may be moved to the position of the player character after the attack ends, or the player character may be returned to the position of the virtual camera. Further, instead of moving the player character directly to attack, the player character may be attacked by throwing a weapon such as a knife or a grenade at the position of the target mark 52 without moving the player character.

  In step S22, the content of the “effect” that is activated according to the position of the target mark 52 may be different. For example, when the target mark 52 is within a predetermined range including the virtual camera, the player character performs an attack using a sword, and when the target mark 52 is outside the range, an attack such as throwing a weapon or shooting is performed. Do. In this way, an appropriate attack may be automatically selected and executed according to the position (interval) of the target mark 52. Note that the “effect” in step S22 is not limited to the attacking action on the enemy character. For example, the player character may be simply jumped to the position of the target mark 52.

  By the way, when the user does not operate the first operation unit 251 and presses only the second operation unit 252, the target mark 52 is not displayed on the game image 50. In this case, in step S21, a predetermined position such as the position of the virtual camera or the position of the player character may be acquired as the position of the target mark 52, and the process of step S22 may be performed. In addition, when the second operation unit 252 is pressed, the effect to be activated may vary depending on whether the first operation unit 251 is operated or not. In step S21, “the position of the target mark 52” is acquired. Instead, “the displacement amount of the first operation unit 251” may be acquired. Both are substantially the same.

  By providing the configuration as described above, the game can grasp the distance (interval) to the target in the depth direction. For example, the game can accurately hit an enemy character in the depth direction. Or jumping to a target position in the depth direction (for example, across the river).

(Modification)
A limit may be set for the length of the gauge 51 shown in FIG. 4 in the depth direction. For example, when the player character is equipped with a throwing weapon, the gauge 51 is displayed with the farthest position reached when the weapon is thrown as a limit. That is, the gauge 51 is displayed within the range where the attack of the player character is effective. As a result, it can be determined whether or not the currently equipped weapon can effectively damage the enemy character at hand, and an appropriate weapon can be selected. In this way, the gauge 51 length may be changed according to the type of weapon, and in addition, the gauge 51 length may be changed according to the status of the player character.

  When the player character jumps to the position of the target mark 52, the gauge 51 may be displayed up to the farthest arrival point that can be reached by jumping. Thereby, it is possible to grasp whether or not the player character can be reached by jumping to a point considered by the user before the actual jump by trying to align the target mark 52 in advance.

  Further, whether or not the orientation of the virtual camera and the vertical and horizontal positions of the gauge 51 and the target mark 52 are linked may be varied depending on the zoom rate of the virtual camera. For example, when the zoom ratio is small and a wide range of the virtual game space is displayed on the display 19, the two are linked. On the other hand, when the zoom ratio is large and a part of the virtual game space is enlarged and displayed on the display 19, the direction of the virtual camera is not changed in response to the operation of the third operation unit 253, and the gauge 51 and the target mark Displace only 52. As a result, the target mark 52 can be accurately positioned with respect to a small distant target.

  When there is an object that becomes an obstacle in front of the virtual camera, the gauge 51 and the target mark 52 may be displayed up to the front of the object, or may be displayed through the object. . In the latter case, the user can distinguish between the front side and the other side of the obstacle by changing the color of the gauge 51 and the target mark 52 or changing the color or transparency of the obstacle. Is preferred.

  The present invention can be applied to a game program and a game system that realize a game that is played in a three-dimensional virtual game space and that allows the user to easily understand the distance (distance) in the depth direction.
