Description

  The present invention relates to a hunting game apparatus in a video game. In particular, the present invention relates to a game apparatus that allows a player to play a game for hunting a prey appearing on a screen by operating a gun controller.

  2. Description of the Related Art Conventionally, a shooting (shooting) game apparatus has been produced in which a shooting operation is performed on a certain target in a screen, and bullets are hit on a large number of targets to compete for scores. In particular, as one aspect of the shooting game, the shooting target is a prey such as an animal appearing on the screen, and a hunting game that reproduces an actual hunting by simulating a rifle or a shotgun for performing a shooting operation The device is known.

  In such a hunting game apparatus, conventionally, a player is aiming at a prey that appears to jump into the screen with a gun controller and performing a trigger operation, thereby causing the gun controller to aim on the screen. The game device detects the position, determines whether or not a prey image is displayed at the position, and determines whether or not the prey has been stopped.

In the conventional hunting game apparatus, the movement of the prey in the screen is a continuous movement, and there is a problem that the reality of the hunting game is poor and the player quickly gets bored with the game. For example, Patent Document 1 describes that a model is moved using movement and shape data.

Thus, it is preferable to determine whether to change the movement of the prey to a movement based on the emergency movement data.

  This gun level indication value is a numerical value related to the level of the gun shot (firing sound) of the weapon selected by the player. For example, a large value is given to a shotgun or a rifle, Is given a small value. For example, if the predetermined threshold is set to a value between these values, the movement data will be emergency movement data so that the prey escapes by gunshot for shotgun and rifle launch, and It is possible to set the movement data so that the prey does not run away.

  Further, the predetermined threshold value can be set according to, for example, the type of prey. For example, a timid prey can have a smaller value and a non-timid prey can have a larger value. As a result, it is possible to bring a situation in which a prey reacts to a gunshot to an actual prey. Moreover, this predetermined threshold value can be set according to the distance from the appropriate position in the three-dimensional virtual space to the prey, for example. This appropriate position is, for example, a viewpoint for perspective transformation. This makes it possible to reproduce the difference in response to the firing sound when the prey is near and far away.

  As another aspect of the present invention, a method for operating a hunting game apparatus is provided. That is, in the present invention, it is a step of storing the shape data and motion data of the prey in the three-dimensional virtual space in the storage means in association with each of the prey, and the prey by the gun firing is stored in the motion data.

It can be reproduced in a three-dimensional virtual space. As a result, the movement of the prey, particularly the movement of being wary or escaping from the gun firing, can be reproduced well, and the realistic hunting state is reproduced. Thereby, the player can take a tactic that is effective in actual hunting, such as delaying the firing as much as possible, and a game device that does not get tired even if played for a long time is realized.

  In the present invention, when the shape is changed in addition to the movement of the prey, the shape of the prey can be adjusted when the prey is wary or escapes, and it is preferable that a more realistic hunting state is reproduced. is there.

  In the present invention, when different gunshot level indication values are used depending on the type of weapon, the magnitude of the gunshot of the actual weapon can be reflected, and a more realistic hunting situation can be reproduced.

Hereinafter, the hunting game device of the present application will be described with reference to the drawings.
FIG. 1 is an external perspective view of a hunting game apparatus 1 according to an embodiment of the present invention. The housing 2 of the hunting game apparatus 1 includes a screen 4, a coin insertion unit 8, and a coin return unit 10. The coin insertion unit 8 and the coin return unit 10 are used to accept coins as a price for the game at the start of the game by accepting coins necessary for the start of the game or returning unnecessary coins. . Instead of or in addition to the coin insertion part 8 and the coin return part 10, an interface of a magnetic card or an IC card can be provided, and the price of the game can be collected by the card. On the screen 4, a projected image (an image subjected to perspective transformation or the like) onto a plane having a three-dimensional virtual space is displayed. In this three-dimensional virtual space, the shape and movement of the prey are simulated.

  FIG. 2 shows a display example of the screen 4. In FIG. 2, a state 40 of a winter mountain where actual hunting is performed is displayed. In the present embodiment, the state 40 of Noyama where these huntings are performed is also reproduced in the three-dimensional virtual space by the three-dimensional model. That is, topography such as undulations on the ground and obstacles such as rocks and vegetation are reproduced three-dimensionally by an appropriate model, and a space where hunting is performed is reproduced in the virtual space.

  Further, in FIG. 2, various animals (images of one deer in the figure) 42 that can be prey even in actual hunting are displayed on the screen 4. This animal is reproduced as a three-dimensional object model such as a polygon model, and an actual animal shape is reproduced in a three-dimensional virtual space by an appropriate technique such as texture mapping. In addition, the movement of the prey animal is simulated in the three-dimensional virtual space so as to reproduce the actual movement. This movement is reproduced, for example, not only the position of the prey at each time but also the direction of the prey, the movement of the extremities and the head, such as the prey running, walking, and eating grass. The animal 42 as a prey is reproduced in the topography and obstacles in the three-dimensional virtual space, and moves as an actual prey. In FIG. 2, only one deer is displayed. However, in the hunting game apparatus 1 according to the present embodiment, a plurality of animals of the same kind or different types are simultaneously displayed and a plurality of animals are displayed in the screen 4. Also, even if they are the same type of animal, a penalty will be imposed on the player if males and females, adults and children are mixed and hunting is prohibited in real hunting. It is also possible to proceed with the game progress. The screen 4 is provided with an icon area for displaying as an icon the weapon type 44 selected by the player, the remaining number of ammunition 46, the type of prey and the number 48 of the prey.

  Returning again to FIG. A flexible cable 64 extends from the housing 2 of the hunting game apparatus 1, and a gun controller 6 (6a, 6b) is attached to the tip thereof. The gun controller 6 can change the position and direction of the player P for the shooting operation. The gun controller 6 is provided with a trigger 62 (trigger operation input means). The player P looks at the image displayed on the screen 4, targets the prey displayed in the screen 4, and activates the trigger 62. When the trigger 62 is activated, the input / output interface unit 22 of the game control device 100 (FIG. 3) in the housing 2 connected to the trigger 62 through a flexible cable uses the trigger 62 as a signal. receive. The gun controller 6 includes a plurality of gun controllers 6a and 6b in order to enjoy a game in various play modes such as a battle play in which two players compete for hunting results and a game in which hunting results are competed by a plurality of teams. Can be equipped.

  FIG. 3 shows a configuration of the game control apparatus 100 of the present invention. The game control device 100 includes a central processing unit (CPU) 14, a main storage device (MEM) 16, a storage device 18, a video control unit 20 that outputs a video signal to the screen 4, an input / output interface unit (I / O) 22, And it has the bus | bath 12 which connects these. Each element may be appropriately provided with a dedicated device or may be constituted by a plurality of elements in order to increase the processing speed. For example, the bus 12 is provided with a video processing bus that requires high-speed processing, the CPU 14 is provided with a dedicated processing unit for three-dimensional processing, and the video control unit 20 is dedicated to polygon drawing processing. Can be provided. The main storage device 16 is an arbitrary memory used by the CPU 14 for calculation, and an arbitrary RAM, a virtual memory, or the like can be used. The storage device 18 is a general nonvolatile storage device, and for example, various fixed and removable nonvolatile storage devices such as a hard disk device, a mask ROM device, a CD-ROM device, and a DVD-ROM device can be used. The storage device 18 stores various data and tables necessary for the progress of the game, executable programs, and the like, and appropriately reads information based on instructions from the CPU 14 to advance the game. The game control device 100 has a function of controlling the game by controlling each element of hardware such as the gun controller 6 and the screen 4 used in the hunting game device 1.

  The input / output interface unit 22 is connected to a controller that receives game operation inputs. In the present embodiment, a gun controller 6 is connected as this controller. The operation of the trigger 62 of the gun controller 6 is transmitted as a signal to the CPU 14 through the input / output interface unit 22. In addition, a coin counter 8 a of the coin insertion unit 8 and the like are connected to the input / output interface unit 22 to receive an external signal for controlling the entire hunting game apparatus 1.

  Next, FIG. 4 shows a functional configuration of the hunting game apparatus 1. This configuration is a functional configuration for causing each hardware element of the hunting game apparatus 1 to operate as a game apparatus in cooperation with each other, and a function when the game control apparatus 100 advances the game by a program in the storage device 18. It is the above configuration.

  The hunting game apparatus 1 advances the entire game under the control of the game progress control unit 72. The game progress control unit 72 starts a game in response to a signal from the coin counter 8a, and performs a game progress process, a game scoring process, a credit process, a game end process and the like when the game progresses through a plurality of stages. Control. A program 888 for this control is stored in the storage means 88 in advance.

  When the game progresses and the game progresses and reaches the stage where the player performs the hunting game, the game progress control unit 72 causes the three-dimensional virtual space generation unit 74 to generate backgrounds such as topography of the mountain and obstacles necessary for the game progress. . At this time, the three-dimensional virtual space generation unit 74 stores various data such as terrain, obstacle arrangement and shape stored in advance in the storage unit 88 according to the stage, and the kind of prey that should appear on the stage. 886 is called from the storage means 88. The three-dimensional virtual space generation unit 74 generates terrain, obstacles, prey, etc. according to the data in the three-dimensional virtual space, and operates them. At this time, the three-dimensional virtual space generation unit 74 instructs the prey movement calculation unit 76 to generate a prey, and causes the prey movement calculation unit 76 to simulate the shape and movement of the prey in the three-dimensional virtual space. Note that the term “prey” here generally refers to an animal that should not be a target for hunting that imposes a penalty on the player, in addition to a target animal for hunting that gives a score to the player in a hunting game.

  When the prey movement calculation means 76 is instructed to generate a prey by the three-dimensional virtual space generation unit 74, it calls the data 890 of the shape of the prey and the movement of the prey in the three-dimensional virtual space from the storage means 88. Based on the above, a polygon model of an animal to be a prey is generated, the shape of the prey is determined by a technique such as texture mapping processing, and the prey object is operated in a three-dimensional virtual space. The shape generally refers to a shape determined by modeling of a three-dimensional object, and an appearance including a pattern and a color. The prey can be, for example, various wild animals such as bears, deer, rabbits, birds, raccoon dogs, elk (mousse, elk), and the like. The movement of the prey object is the position of the prey at each time in the three-dimensional virtual space, that is, the movement path and speed, and the movement of the prey limb and body. The shape and movement data 890 is associated with an appropriate clock signal indicating each time of progress of the game, and includes data necessary for operating the prey object in accordance with the progress of the game.

  On the screen 4, an image or video that is a background of hunting generated by the three-dimensional virtual space generation unit 74 and an image or video of a prey generated by the prey motion calculation means 76 are perspective-transformed. Is displayed. Video data of such an image or video that is perspective-transformed and displayed on the screen 4 is generated by the projected image generation means 78. The display means in the present application includes the projected image generation means 78 and the screen 4 in FIG.

  When the projected image of the three-dimensional virtual space is displayed on the screen 4 as described above, the player P moves the real direction and the real direction of the gun controller 6 to aim at the prey appearing on the screen 4. The trigger 62 is operated. The trigger operation input is detected by the detection means 82. The detecting means 82 further detects the actual position where the gun controller 6 aims at the screen 4 of the display means and the actual direction of the gun controller 6 with respect to the screen 4 during the trigger operation. The detection unit 82 outputs a signal indicating that the trigger input operation has occurred to the prey operation calculation unit 76. The detection means 82 is realized by using, for example, the input / output interface 22, the bus 12, and the CPU 14 in FIG. 3, and the function is realized by interrupt control to the CPU 14. The gun controller 6 can use various position and direction detection means. For example, when the screen 4 is a display screen such as a CRT that performs raster scanning, a light receiving element that receives front light is provided at the muzzle portion of the gun controller 6, and the screen 4 is displayed by one frame or according to a trigger operation input signal. The position indicated by the gun controller 6 on the screen 4 can be detected based on the detection timing of the light of the display, such as white display of the entire screen for only one field. As another example, a position detection sensor of the gun controller 6 may be provided around the screen 4 to detect the direction indicated by the gun controller 6. In addition, a device using a magnetic sensor can also be used for detection of an actual position and an actual direction where the gun controller 6 by the detection means aims on the screen. Note that the actual position where the gun controller 6 is aimed on the screen 4 can be specified by (X, Y) coordinates on the image indicating which position on the two-dimensional screen 4 is aimed. The actual direction in which the gun controller 6 aims at the screen 4 is the direction indicated by the gun controller in the space on the player P side of the screen 4 and can be specified by the elevation angle, the azimuth angle, and the like.

  The actual position and the actual direction of the gun controller 6 detected by the detecting unit 82 are input to the bullet trajectory calculating unit 84 and used for calculating the trajectory of the shooting operation in the three-dimensional virtual space. The trajectory of the bullet in the three-dimensional virtual space is input to the determination means 86. The determination unit 86 determines the overlap between the trajectory of the bullet and each of the spatial regions associated with the prey, for example, at the trigger operation time or when a predetermined time has elapsed from the trigger operation. The trigger operation time point is a time point when the detection unit 82 receives a trigger operation input signal, and the predetermined elapsed time point is a process by the detection unit 82, a process by the bullet trajectory calculation unit 84, and a determination unit from the reception time point. This is after the time required for processing such as processing by 86 or after the elapse of a preset time. For the spatial region determined to have an overlap with the bullet trajectory by the determining means 86, an area ID (identifier) for identifying the spatial area is output to the prey operation calculating means.

Here, the storage means 88 stores the damage level that the prey receives from the bullets in association with the area ID of each space area. The area ID can be configured by, for example, an ID of a prey and an ID of an area in the prey. The damage level is a numerical value of damage taken by a prey when the space area is attacked by a predetermined bullet. For example, a physical strength value is associated with each prey as a numerical value corresponding to the physical strength of the prey at each time point, and the physical strength value when the prey is shot (new physical strength value) = (previous physical strength value) ― (Damage level)
It is possible to operate so as to cause the prey to die when the stamina value falls below a predetermined value. The prey movement calculation means 76 includes search means 762 for searching the storage means 88 for damage levels associated with a space area that overlaps the bullet trajectory based on the area ID from the determination means. Thereby, the prey movement calculation means 76 can obtain the damage level corresponding to the space area for each space area overlapping with the bullet trajectory.

  Here, the shape and movement data 890 stored in the storage unit 88 of the hunting game apparatus 1 of the present embodiment includes a plurality of movement data 884. The movement data 884 is data for reproducing the movement of a prey during hunting. For example, the movement data includes data for moving a prey object by movement until the prey hears a gunshot (normal time movement data), and data for moving a prey object by movement after the prey hears the gunshot ( Emergency motion data). In this example, normal-time movement data shows that if the prey is a deer, the deer will be resting without particular warning, the deer eating food such as grass, or simply deer for movement. It can be used as data for moving the deer object by movement such as the movement of walking. In addition, the emergency movement data can be used to identify deer objects by movements such as deer being alert and raising their heads, deer sprinting to escape, and deer hiding behind obstacles. It can be data for moving. As described above, the normal-time motion data and the emergency motion data are given so as to simulate the action that the prey takes in the actual hunting scene according to the type of the prey. As a result, the movement of the prey object that is close to the movement of the prey after firing a gun in actual hunting is reproduced, so that the movement of the prey that is closer to reality is reproduced on the game. Note that the motion data can be data for operating the object by an existing method that can generate the motion of the object in the three-dimensional virtual space, such as a key frame method or a skeleton method.

  When the prey movement calculation unit 76 receives a signal indicating that the trigger input operation has occurred from the detection unit 82, the prey movement calculation unit 76 changes the movement of the prey according to the emergency movement data included in the movement data 884. Although not shown, when the emergency shape data is included in the shape data, the shape of the prey can be changed according to the emergency shape data. Similarly to the motion data, the shape data can also be composed of normal time shape data and emergency motion data. When the prey is a deer, the normal time shape data can be, for example, data for realizing the appearance of the deer when the deer is resting without particular vigilance on the deer object. Further, the emergency shape data can be data for realizing the appearance of an excited deer as a deer object.

  In the hunting game apparatus according to another embodiment, the game progress control unit may be provided with weapon selection receiving means for receiving a weapon selection by the player. In the weapon selection, for example, several kinds of weapons that can be selected are displayed on the screen 4 together with the characteristics of the weapons, and the player can select them before or during the game. The feature of the weapon is that a weapon with a large number of bullets but a small power or a weapon with a small number of bullets but a large power can be selected. In addition, as one of the features, the magnitude of the firing sound can be included. As an example of this weapon, for example, a weapon used for actual hunting such as a shotgun, a rifle, and a bowgun can be selected.

  Further, in the hunting game apparatus of such an embodiment, a numerical value (gunshot level instruction value) indicating the firing sound for each weapon is stored in the storage means as the file 882, and this gunshot level instruction value is the search means 762. Can be searched by. The gun level indication value is used as a numerical value indicating a stimulus given to the prey at the hunting ground when the weapon used in the game is fired by the player P. The gun level indication value is, for example, a gunshot sound generated by gunpowder. A large value can be given to the accompanying shotgun and rifle, and a small value can be given to a bowgun that does not accompany the gunshot firing sound, but it is not necessarily related to the magnitude of the gunfire of an actual weapon. At this time, the prey movement calculation means 76 reads the gun level indication value according to the weapon selected by the player P, and uses the movement data 884 for simulating the shape and movement of the prey object according to the value. Can be switched.

  The motion data and the game operation using the motion data will be described in detail with reference to FIGS. FIG. 5 is an explanatory diagram showing the types of motion data. The motion data includes, for example, first to third types of normal-time motion data M1 to M3 and first to third types of emergency motion data EM1 to EM3. For example, the first to third normal-time motion data are data on the motion of the deer resting without particular vigilance, data on the motion of the deer eating grass, etc. It is the data of the movement which is walking. In addition, the first to third emergency movement data are respectively data of movements where the deer is alert and raising their heads, data of movements of the deer sprinting to escape, and deer hiding in an obstacle. It is data of movement to escape.

  FIG. 6 is a flowchart showing a method for operating a hunting game apparatus according to an embodiment of the present invention. The storage means stores prey shape data and movement data in advance (step S2). After the game starts (step S4), the prey movement calculation means 76 simulates the shape and movement of the prey according to the shape data and the movement data 890 (step S6). For example, when one prey appears, the prey movement calculation means 76 uses a predetermined or randomly selected one from the first to third types of normal-time motion data M1 to M3 (FIG. 5). Use to simulate prey movements. In this way, each object such as the background and prey in the three-dimensional virtual space is displayed on the screen of the display device as a projected image (step S8). As a result, the movement of the prey in the three-dimensional virtual space is displayed on the screen 4 of the display device that is visible to the player P. When the player P operates the trigger by operating the position and direction of the gun controller, and the hunting game apparatus 1 receives the trigger operation input signal (step S10), the hunting game apparatus responds to the trigger operation time or its It is determined whether a bullet has hit the prey when a predetermined time has elapsed from the trigger operation (step S12). When a bullet hits a prey, for example, when a shot is hit, the damage of the prey is judged, a score is added according to the prey, or the movement of the prey is changed to the movement when hit. Is performed (step S14). On the other hand, when the bullet does not hit the prey, for example, the gun voice level instruction value of the weapon selected by the player P is called from the file 882 and the value is compared with a predetermined threshold value. Then, the movement of the prey is changed to that based on the emergency movement data (step S18). As a result, the prey movement calculation means 76 simulates the movement of the prey based on any of the first to third types of emergency movement data EM1 to EM3 (FIG. 5). After changing the shape and movement of the prey to those based on emergency motion data, etc., the game is repeatedly executed by going back to an appropriate processing procedure in order to proceed as it is. If such a process is repeatedly executed at appropriate time steps, even if the player does not hit a bullet, the prey will be wary of the gunshot in response to the player operating the gun controller trigger. You can reproduce the situation of running away or hiding behind an obstacle. Although not shown, when emergency shape data is stored in the storage means, the appearance of a more realistic prey can be reproduced by switching the shape data to emergency shape data at the same stage as step S18. .

  Further, as is clear from FIG. 6, when the game is started and the trigger is operated at least once and the prey is in a state simulated based on the emergency motion data, the player P further moves the position of the gun controller. If the hunting game apparatus 1 receives the trigger operation input signal by operating the trigger by operating the direction, the prey motion can be changed to the one based on the emergency motion data (S18). At this time, for example, emergency motion data different from the emergency motion data used immediately before may be selected, or may be selected, for example, randomly from a plurality of emergency motion data. As a result, it is possible to reproduce the appearance of a prey that has been fired multiple times but not hit by being wary of a subsequent shot or running away with surprise. In the case of performing this random selection, for example, the prey motion calculation means 76 may include a random number generation means and a random selection means for selecting emergency motion data from the random number. Also, motion data may be selected based on some rule. For example, it is possible to switch from emergency motion data that can reproduce a relatively calm prey motion to emergency motion data that can reproduce a more confusing prey motion.

  Returning to FIG. 5 again, a case where motion data is selected and switched based on a rule will be described. Here, it is assumed that one deer is generated as a prey in the three-dimensional virtual space. Although not shown, the storage means 88 (FIG. 4) stores transition rule data for selecting motion data, and the prey motion calculation means 76 can sequentially switch motion data with reference to this transition rule data. it can. First, when a shot is not received for the first time after the game is started, or when a shot is not hit and a bullet is not hit but the gun level indication value is small and the process does not proceed to step S18, the first kind of normal time is used as motion data. The motion data M1 is selected. This selection may be specified in the game progress program. At this time, the deer object is operated by the prey action selecting means 76 (FIG. 4) based on the data of the movement of the deer resting without being particularly wary. Then, when the trigger operation of the gun controller 6 is performed and step S18 in FIG. 6 is reached, the prey operation selection means 76 refers to the transition rule data stored in the storage means 88. When the transition rule data describes the transition from the first type normal-time motion data M1 to the first type emergency motion data EM1, the prey action selecting means 76 selects the motion data to be selected as the first type. Switch to emergency motion data EM1. When the trigger operation of the gun controller 6 is further performed and each time step S18 is reached, the prey operation selecting means 76 similarly refers to the transition rule data and from the first type of emergency motion data EM1, the second The selected motion data is transitioned to the type of emergency motion data EM2 and the third type of emergency motion data EM3. As a result, the movement of the deer's object is sequentially changed according to the firing, for example, the movement of the deer to be alert and raising its head, the movement of the deer to run away, the deer hiding in the obstacle Furthermore, it is possible to switch to a movement different from the movement to escape.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications, changes and combinations can be made based on the technical idea of the present invention. . For example, a predetermined value to be compared with the gun level indication value can be set according to the type of prey. For example, a timid prey can have a smaller value and a non-timid prey can have a larger value. As a result, it is possible to bring a situation in which a prey reacts to a gunshot to an actual prey.
