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. 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. The coin insertion unit 8 and the coin return unit 10 are used to accept a coin as a price for the game at the start of the game by accepting a coin necessary for starting the game or returning an unnecessary coin. . 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.

  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. The state of Noyama where these huntings are performed is also reproduced by a three-dimensional model in a three-dimensional virtual space. In other words, topography such as undulations of 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 realized in the virtual space.

  Further, in FIG. 2, various kinds of animals (in the figure, one deer image) 42 that are prey even in actual hunting are displayed on the screen 4. This animal is reproduced as a three-dimensional model such as a polygon model, and is reproduced like a real animal in the virtual space by an appropriate technique such as texture mapping. In addition, the movement of the prey is simulated in the three-dimensional virtual space so that the prey reproduces the movement of a real animal. This movement is reproduced not only in the position of the prey at each time but also in 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. The player P looks at the image displayed on the screen 4 and targets the prey displayed in the screen 4 to operate the trigger 62. The operation of the trigger 62 is sent to the input / output interface 22 of the game control device 100 (FIG. 3) in the housing 2 through a flexible cable. 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 (VIDEO) 20 that outputs a video signal to the screen 4, and an input / output interface unit (I / O). ) 22 and a bus 12 connecting them. Each element may further include a dedicated device as appropriate, or may be configured by a plurality of elements in order to speed up the processing. For example, the bus 12 is provided with a bus for video processing 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 processing polygon drawing. 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 is connected to the input / output interface unit 22 and receives 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 receives a signal from the coin counter 8a, starts the game, and proceeds with a game progress process, a game scoring process, a credit process, a game end process, etc. To 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. Then, terrain, obstacles, prey, etc. are generated and arranged in accordance with the data in the three-dimensional virtual space and operated. 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 operation calculating unit 76 is instructed to generate the prey by the three-dimensional virtual space generation unit 74, the storage unit 88 calls the prey shape and prey movement data 890 in the three-dimensional virtual space. Based on this, a polygon model of an animal to be a prey is generated, the shape and appearance of the prey are determined by a technique such as texture mapping processing, and the prey is caused to perform a predetermined operation. The prey can be, for example, various wild animals such as bears, deer, rabbits, birds, raccoon dogs, elk (mousse, elk), and the like. Here, two or more spatial regions in the three-dimensional virtual space are identifiably associated with the prey, and each of these spatial regions moves with the prey. Note that the prey movement calculation means 76 can also simulate the shape and movement of the prey in the three-dimensional virtual space in accordance with an instruction from the game progress control unit 72.

  The space region will be described in detail with reference to FIGS. 5 and 6 by taking as an example the case where the prey is a deer 42. FIG. 5 is a display example of a two-dimensional image for showing a player how to set a prey region used in the hunting game apparatus of the present embodiment in order to simulate a portion where damage to deer differs in actual hunting. is there. This region corresponds to the spatial region in the present invention, but is not the same. Regions D1 to D6 are set in the head, neck, torso, inside of the torso, in the vicinity of the heart, and in the waist, respectively. The display shown in FIG. 5 is presented to the player P during the game. Thereby, in the game of the hunting game apparatus 1, shootings to the respective areas D1 to D6 are evaluated as different scores, and even if each area is shot with the same weapon, the player P is notified that the damage is different depending on the area. The This display corresponds to the fact that the damage received by the prey varies depending on the site where the prey is shot in actual hunting, and is used to give the game a reality. For example, in the player P, the areas D1 and D5 are colored red, and the area where the weapon can be shot with a single shot is the head of the deer and the chest. Inform that there is one by one. The region D4 is shown in orange, and the player P shows that there is a region that can be damaged greatly around the region D5 adjacent to the region D5. Furthermore, the region D3 is colored yellow to indicate to the player P that the region D3 is a region corresponding to the region D4, the regions D2 and D6 are colored green, and the regions D2 and D6 are It indicates to the player P that the area conforms to the area D3. Other areas are displayed in the color of the deer's appearance.

  FIG. 6 shows the shape (a) of a prey deer in the hunting game apparatus 1 of the present embodiment and the setting (b) of the corresponding space area. FIG. 6 a is a diagram illustrating the shape of the deer 42 in the three-dimensional virtual space. The prey deer 42 can move in various ways in the three-dimensional virtual space like an actual deer. The shape of the prey deer 42 can be described by a polygon model, for example. FIG. 6b shows an example of a set 36 of spatial regions (a collection of spatial regions) in the three-dimensional virtual space associated with the deer of FIG. 6a. This set 36 of spatial regions includes a spatial region corresponding to each region in FIG. 5 and a spatial region that does not correspond. In the example shown in FIG. 6b, the space areas A1 to A6 correspond to the areas D1 to D6 in FIG. 5, respectively. Further, the space areas A11 to A20 do not correspond to the areas D1 to D6 in FIG. Spatial regions A1 to A6 and A11 to A20 are associated with each part of the prey deer in the three-dimensional virtual space, and move in the three-dimensional virtual space in accordance with not only the movement of the deer but also the movement of the body. Change the position and orientation. Moreover, this space area | region can be made into the area | region enclosed by external shapes, such as a rectangular parallelepiped, a spherical body, and a spheroid. The set of spatial regions can be a combination of these relatively simple shapes, and a simpler shape than the polygon indicating the shape of a prey deer or a polygon shape can be used. In addition, the spatial areas included in the set 36 of spatial areas may overlap each other, may be completely included in other spatial areas, or may be spatial areas that do not overlap each other at all. Can do. The space areas A1 to A6 and A11 to A20 are used for determining the overlap with the bullet trajectory, and are illustrated for explanation and are not drawn on the screen 4.

  Returning to FIG. 4, the description will be continued. 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 determines the gun barrel of the gun controller 6 as a prey on the screen 4 and operates the trigger 62. A trigger operation input signal is input to the detection means 82. The detection means 82 detects the actual position where the gun controller 6 aims at the screen 4 of the display means and the actual direction with respect to the screen 4 of the gun controller 6 during the trigger operation. 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 entire screen can be displayed uniformly in one field such as white, and the position indicated by the gun controller 6 on the screen 4 can be detected by the detection timing of the light of the display. 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 calculation of the bullet trajectory will be described in detail with reference to FIGS. FIG. 7 is a layout diagram showing the configuration of objects in the three-dimensional virtual space. In the hunting game apparatus of the present embodiment, trees 32 and rocks 34 are arranged in a three-dimensional virtual space, and prey deer are eating grass. The prey 42 of the prey is expressed by a set 36 of space areas for the sake of explanation. The rectangular surface 38 is a surface (projection surface) that serves as a reference for calculation for obtaining a display of the screen 4 (FIG. 1 and the like) by perspective-transforming the three-dimensional virtual space into the viewpoint 30. For reference, the display on the screen 4 of the tree 32, the rock 34, and the deer 42 is shown on the surface 38.

  Here, since the projected image of the light beam that converges on the viewpoint 30 is drawn on the screen 4, what is represented by a point on the screen 4 is a straight line passing through the viewpoint 30 and intersecting the plane 38 in the three-dimensional virtual space. . Therefore, for example, when the prey deer 42 displayed on the screen 4 is aimed by the gun controller 6, the bullet trajectory departs from the viewpoint 30 under the condition that the bullets fly in the depth direction of the screen. Thus, a straight line passes through a point on the surface 38 corresponding to the target point on the screen 4. This corresponds to the situation in which the bullet passes as if it was fired from the viewpoint 30 toward the point on the screen in the three-dimensional virtual space, as indicated by the arrow 302. This straight line is the same as the straight line in the three-dimensional virtual space of the projected ray passing through the point on the surface 38 corresponding to the target point on the screen 4. Accordingly, by determining the overlap between such a straight line and each of the spatial region sets 36 associated with the prey deer 42, it is possible to determine which spatial region overlaps with the bullet trajectory.

  FIG. 8 is a plan view of the three-dimensional virtual space shown in FIG. The trajectory of the bullet is a trajectory in a three-dimensional virtual space through which a projected ray to the surface 38 corresponding to the point on the screen 4 passes. FIG. 9 is a plan view showing a state of projection in the case where an image on the screen 4 is obtained by projecting onto the plane 38 in parallel, instead of perspective transformation that projects so as to converge to a specific viewpoint. Even in this case, the trajectory of the bullet is a trajectory in a three-dimensional virtual space through which a projected ray to the surface 38 corresponding to the point on the screen 4 passes.

  In any of the cases shown in FIGS. 8 and 9, a projection ray to the surface 38 corresponding to the point on the screen 4 passes under the condition that the bullets fly as they are in the depth direction of the screen. The trajectory of the bullet is calculated from the trajectory in the three-dimensional virtual space. In this case, in the real space aiming at the screen 4 in the hunting game apparatus 1, as shown by the arrow 312 in FIG. 8, a certain position on the screen from a position not necessarily corresponding to the viewpoint 30 in the three-dimensional virtual space. Even if it aims, it has the advantage that the trajectory of the bullet can be calculated based only on the aimed position on the screen.

  Although not shown in the drawings, the present invention is not necessarily limited to the condition that the bullets fly as they are in the depth direction of the screen. For example, by considering not only the actual position where the gun controller 6 aims at the screen 4 but also the actual direction of the gun controller with respect to the screen, for example, even when aiming at a different position on the screen, the same prey is hit. You can also

  Returning to FIG. 4, the description will be continued. The trajectory of the bullet in the three-dimensional virtual space is input to the determination means 86. The determination means 86 determines the overlap between the trajectory of the bullet and each of the spatial regions at the time of the trigger operation 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, in the storage means 88, the damage level that the prey receives by the bullets is stored as a table 882 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, in the shape and movement data 890 stored in the storage unit 88 of the hunting game apparatus 1 of the present embodiment, data of a plurality of shapes associated with the region ID and the damage level received by the region. And motion data 884 are included. The shape data and the movement data 884 are data for reproducing the shape and movement of a prey that has been shot at a portion corresponding to the space area specified by the area ID. For example, if the prey is a deer and the space area corresponding to the forefoot part overlaps with the bullet trajectory, it corresponds to the forefoot part being shot on the screen 4 of the game. The shape data and movement data 884 include the shape and movement data such that the shape and movement of the deer of the prey are the shape and movement of dragging the forefoot with respect to the area ID of the corresponding space area. . In this example, because the shape and movement data is different from the data when the deer was shot on the hind legs, for example, the movement of the hunting prey closer to reality is reproduced, so the same prey Even so, the movement of the prey that is closer to reality is reproduced by using different shape and movement data for each area ID of the spatial area. In the present invention, the shape data and the movement data are not associated with the damage level but are associated with only the region ID, or the data and region associated with the combination of the region ID and the damage level. It is also possible to use data in which data associated only with IDs is mixed. When using data associated only with the area ID, for example, the damage level is used to determine whether the prey motion calculation means 76 calls the data, and the area of the space area that has been shot as necessary Shape data and motion data associated only with the ID can be used. In other words, the prey movement calculation means 76 changes the shape and movement of the prey according to the shape and movement data retrieved from the area ID and the damage level based on the area ID and the searched damage level. As a result, the shape and movement of the prey become a highly realistic shape and movement, and the player of the hunting game can enjoy a hunting game that is close to reality.

  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. 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 this embodiment, the damage coefficient for each weapon is stored in the storage means, and the damage coefficient can be searched by the search means 762. This damage coefficient is multiplied by the damage level and used to calculate a new damage level. For example, a large damage coefficient is set for a weapon with high power, and the prey operation calculating means 76 can operate so as to subtract the product of the damage level and the damage coefficient from the physical strength value of the prey. At this time, the prey operation calculating means 76 can change the shape and operation of the prey based on the region ID (identifier) and the new damage level calculated by multiplying the damage level by the damage coefficient.

  In another embodiment of the present invention, when there are a plurality of space areas that overlap with the trajectory of bullets in one prey, and the damage level associated with each space area is different, the prey operation calculating means has a high damage level. By adopting the spatial area, the shape and operation of the prey can be changed based on the identifier of the spatial area and the damage of the spatial area. For example, as shown in FIG. 6b, when the space region A4 is arranged inside the space region A3 and the space region A5 is arranged inside the space region A3, the bullet trajectory and the region A5 overlap. In this case, the space area A4 and the space area A3 inevitably overlap with the bullet trajectory. In this case, by configuring as described above, it is possible to determine which space area is hit by a bullet when a plurality of area IDs are output from the determination means 86 shown in FIG. it can. Thereby, in actual hunting, a situation close to a state in which bullets pass through the body of the prey can be reproduced, and a hunting game apparatus with high reality is realized.

  In still another embodiment of the present invention, when there are a plurality of space areas in one prey that overlap with the bullet trajectory, the prey motion calculating means is a space area on the near side, that is, on the viewpoint side in the three-dimensional virtual space. And the shape and behavior of the prey can be changed based on the identifier of the space area and the damage of the space area. For example, as shown in FIG. 6b, in the case where the space area A6 is arranged adjacent to the space area A3, depending on the direction of the prey in the three-dimensional virtual space, the space area A3 and the space area A6 The bullet trajectory may overlap for both. In such a case, by configuring as described above, when a plurality of region IDs are output from the determination means 86 shown in FIG. Can do. For example, when there is a space area A6 on the front side (that is, when the prey is facing the rear), the bullet hits the space area A6, and conversely, when there is a space area A3 on the front side. In other words, when the prey has its head facing forward, the bullet hits the space area A3. Thereby, in actual hunting, it is possible to reproduce a situation close to a state in which bullets do not pass completely through the body of the prey, and a highly realistic hunting game apparatus is realized.

  The present invention can be implemented as a method for operating a hunting game apparatus, for example. An embodiment in this case is shown in FIG. In this embodiment, the prey shape data and prey movement data in the three-dimensional virtual space are stored in the storage means, and the damage level that the prey receives from the bullet is stored in the storage means in association with each of the identifiers in the space area. (Step S2). Here, the shape data includes data of a plurality of shapes associated with each of the identifiers, and the motion data includes data of a plurality of motions associated with each of the identifiers. When the game is started by inserting coins (step S4), the shape and movement of the prey are generated in the three-dimensional virtual space (step S6). Here, at least a plurality of spatial regions are associated with the prey in an identifiable manner. Each object such as the background and prey in the three-dimensional virtual space is displayed as a projected image (step S8). When the player operates the trigger by operating the position and direction of the gun controller, and the hunting game apparatus receives a trigger operation input signal (step S10), the actual position and the actual position where the gun controller aims on the screen of the display means. A direction is detected (step S12). In response to this, the hunting game device calculates the trajectory of the shooting operation bullet in the three-dimensional virtual space from the detected actual position and actual direction (step S14). Thereafter, the hunting game device determines the overlap between the bullet trajectory and each of the space regions at the trigger operation time or when a predetermined time has elapsed from the trigger operation (step S16). An identifier of a spatial region having an overlap with the bullet trajectory is obtained (step S18). Based on this identifier, the hunting game device searches the storage means for a damage level associated with the space area that overlaps the bullet trajectory (step S20), and based on the identifier and the retrieved damage level. The shape and / or operation of the prey is changed to any one of a plurality of shapes and / or one of a plurality of operations (step S22). If the trigger operation input signal is not accepted in steps S10 and S16 (when the gun controller trigger is not activated), or if there is no overlap between the bullet trajectory and the space area (if the bullet is not hitting the prey), After changing the shape and operation, the process is repeatedly executed up to an appropriate processing procedure in order to advance the game as it is.
