Description

  The present invention relates to a game device, and more particularly to a game device in which a player operates an object displayed on a display means to advance a game.

  For example, there is a game device that is placed in an amusement facility and executes a car racing game. In addition, different game facilities may be connected to a network, whereby game devices between different game facilities may be connected via the network, thereby enabling a network game.

  In any case, the game apparatus in each amusement facility is provided with a plurality of race car model (car) devices that are approximately the size of a real vehicle.

  Then, the player sits in the driver's seat of the race car and looks at the image displayed on the monitor by the program, and operates the steering wheel, shift lever, accelerator, etc. The game which competes for the time to reach the goal with a small number of collisions by operating the means is executed.

  Furthermore, there is a game device for performing a race competition placed in such a play facility, in which two players sit on a model of a race car and two players sit and execute a car race game. It has been.

  With regard to such a game apparatus, the applicant of the present application (Patent Documents 1 and 2) may not recognize any of the operation means for sending the operation signal to the control means for controlling the progress of the game. We propose a replacement process that makes the player's operation effective.

  That is, in the invention described in Patent Document 1 as the first prior invention, the common operation object is one racing car in which a plurality of players move in a virtual space with a model device in a common real space. A game apparatus has been proposed that realizes operation change among a plurality of players in a game apparatus.

  Furthermore, the invention described in Patent Document 2 which is the second prior invention is based on the first prior invention, and is based on the assumption that there is a plurality of players in a game device having one racing car as a common operation target. A game apparatus has been proposed that enables game development that is advantageous to the user by using operation change.

  In such a game device, the two-dimensional image displayed on the monitor has a vanishing point that becomes smaller as the distance increases, such as a landscape in a three-dimensional space image or a straight course, and eventually converges to a point. Therefore, when the position of the vanishing point coincides with the point in the line-of-sight direction for a player observing the monitor, it feels uncomfortable.

In the invention of the prior application, the two players advance the game while watching the race image displayed on the common monitor screen. In the game device according to the prior application, a single racing car in which a plurality of players move in a virtual space is a common operation target in a model device in a common real space. Even in the case of processing of operation change, images displayed on a common monitor are processed as a common one.
Japanese Patent Application No. 2006-145842 Japanese Patent Application No. 2007-307518

  In the above Patent Documents 1 and 2, the position of each player sitting in front of a common monitor is different, but even if there is an operation change, the screen displayed on the common monitor is the same, and the player With the change of operation, the line-of-sight direction of the corresponding player was not taken into consideration. That is, for example, in a drive game, it is common for a player to perform a game operation in a line-of-sight direction that coincides with the center of the running course, and there is no sense of discomfort.

  In addition, unlike a game device placed in a play facility, it is a personal-use game device that uses a plurality of input devices connected to the game device through a code so that a plurality of players can display objects displayed on a monitor. There is also a mode in which a game is executed by operation.

  Even when a plurality of players operate and execute a game in such a personal specification game device, a player replacement process is assumed in the same manner as described above.

  Or, in such a game device, even when the relative position of the player to the monitor changes, the player feels uncomfortable in the operation of the game in relation to the position of the vanishing point on the monitor screen and the direction of the player's line of sight. Sometimes.

  That is, the direction of the player's line of sight and the position of the vanishing point on the screen are different, which may cause a sense of incongruity.

  Accordingly, an object of the present invention is to provide a game apparatus that reduces the uncomfortable feeling caused by the disagreement between the vanishing point and the line-of-sight direction based on the change of the player's operation or the positional relationship of the player with respect to the monitor.

  A game device according to the present invention that achieves such an object is a game device having a predetermined viewing angle in a line-of-sight direction of a viewpoint camera position and a virtual three-dimensional space within a range having a predetermined distance in a Z-axis direction. An object is projected onto a two-dimensional screen coordinate system having an origin at a point that intersects the line-of-sight direction to generate two-dimensional image data. Further, the generated two-dimensional image data includes a region of a viewport corresponding to a monitor. Image generation means for converting the image data into a viewport coordinate system and drawing it in a graphic memory; and display control means for reading out image data for a viewport area drawn in the graphic memory and displaying it on the monitor; A plurality of operation means provided corresponding to a plurality of players, and operation signals from each of the plurality of operation means are valid based on predetermined conditions Having a control means for.

  Then, the image generation means sets the origin of the viewport coordinate system of the image data corresponding to the area of the viewport drawn in the graphic memory, corresponding to the operation means for which the operation signal is validated by the control means. shift.

  Accordingly, it is possible to deflect the extinction point displayed on the monitor in correspondence with the operation means side on which the operation signal is validated.

  Embodiments of the present invention will be described below with reference to the drawings. The embodiments are for the purpose of understanding the present invention, and the technical scope of the present invention is not limited thereto.

  In particular, examples of car racing games will be described below as examples, but the application of the present invention is not limited to such car racing games. For example, as another example, a plurality of players sit on a model device (competition boat) used for racing competitions such as boat races, and a competition boat appearing on a race game image is shared by a plurality of players. Similarly, the present invention can be applied to the case of an operation target.

  Alternatively, in a shooting game for a common target target, the present invention can be applied even when a shooter who is a player changes, or when the positional relationship between the line-of-sight direction and the target target changes when the shooting position is changed. Is possible.

  FIG. 1 is a configuration example of a game board 212 constituting a game device to which the present invention is applied.

  The program data storage device 221 stores game programs and program data (including video / audio data). The storage device 221 may be composed of an external DVD-ROM or the like.

  The CPU 222 is a processor for executing a program, controlling the entire system, calculating coordinates for displaying an image, and the like.

  The system memory 223 stores programs and data necessary for the CPU 222 to perform processing. Furthermore, data during game execution, such as information on a racing car that is operated in a virtual three-dimensional space and operated by a player, and travel distance, are generated and temporarily stored in the system memory 223.

  Programs and data necessary for starting up the game board 212 are stored in the boot ROM 224.

  Furthermore, a bus arbiter 225 for controlling the flow of programs and data with each block of the game board 212 and devices connected to the outside through the I / O interface 220 is provided, and these are connected to the bus.

  A rendering processor 226 is further connected to the bus. Video (movie) data read from the program data storage device 221 and image data to be generated in response to a player's operation or game progress are generated by the rendering processor 226 and rendered in the graphic memory (video memory) 227. Are read out and displayed on the monitor 21. Graphic data necessary for the rendering processor 226 to generate an image is stored in the graphic memory 227.

  Further, a sound processor 228 is connected to the bus, and music data read from the program data storage device 221 and sound effects and sounds to be generated according to player operations and game progress are generated by the sound processor 228. A sound is displayed on the speaker 30. Sound data and the like necessary for the sound processor 228 to generate sound effects and sounds are stored in the sound memory 229.

  FIG. 2 is a diagram showing a processing flow of image generation corresponding to the player change operation as an embodiment in the game board 212 of FIG.

  This processing flow is executed and controlled by the CPU 222 for each frame of an image in accordance with a game program stored in the storage device 221 when the game device is activated.

  Under the control of the CPU 222, the rendering processor 226 reads the program data from the system memory 223, and converts the data of a plurality of polygons constituting objects of the modeling coordinate system (world coordinate system) in the virtual three-dimensional space into the viewpoint coordinate system. (Step S1).

  The viewpoint coordinate system specifies a range having a viewpoint camera position as an origin, a predetermined viewing angle in the line-of-sight direction, and a predetermined distance z in the Z-axis direction as a rendering range. Within the rendering range, a two-dimensional screen projection coordinate system (x, y) having a point intersecting the line-of-sight direction as an origin is provided.

  FIG. 3 is a diagram for explaining the conversion process to the screen coordinate system.

  The image of the three-dimensional coordinates (X, Y, Z) with the viewpoint camera position EP as the origin is converted to two-dimensional coordinates by projecting the object image within the rendering range onto the projection plane A having the screen coordinate system (x, y). (Step S2).

The two-dimensional data of a plurality of polygons projected and converted to the screen coordinate system is displayed in a range where x and y are −1 ≦ x ≦ 1 and −1 ≦ y ≦ 1.

  However, since the actual display range is restricted by the monitor device, only a specific range within the screen coordinate system range (-1 ≦ x ≦ 1, −1 ≦ y ≦ 1) is displayed on the monitor 21. The This range is called a viewport.

  Therefore, after conversion into two-dimensional coordinates (step S2), viewport conversion is performed (step S3). In particular, such viewport conversion has the features of the present invention and will be described in detail later.

  Next, pixel processing such as shading (shadow by light source), texture mapping, anti-aliasing, and the like is performed on the two-dimensional data subjected to viewport conversion (step S4), and then graphic memory (video memory) 227 is stored as image data in the graphic memory. (Step S5).

  The image data drawn in the graphic memory 227 is read out and displayed on the monitor 21 (step S6).

  Next, the process proceeds to the next frame process, and the process is repeated for each image frame in the same manner as in steps S1 to S6 (step S7).

  FIG. 4 is a diagram showing a detailed flow including a viewport conversion process for specifying a viewport in step S3 of the processing flow of FIG. 2, which is a feature of the embodiment of the present invention, and FIGS. It is explanatory drawing corresponding to.

  Until the process is started and the game is started by the player (step S11, No), an advertisement screen for displaying an image related to the game is displayed (step S10).

  Here, as described with reference to FIG. 3, in the viewpoint coordinate system having the viewpoint camera position EP as the origin, the range of the distance in the Z-axis direction having the predetermined viewing angle in the line-of-sight direction is set as the renderable range. .

  In the normal state, for example, before the game is started by the player in the game device, the advertisement screen is displayed as described above. At this time, in FIG. 3, a three-dimensional space image of the renderable range is projected onto the screen projection plane A centered on the origin of the two-dimensional screen coordinate (projection coordinate) system (x, y, 0).

  FIG. 5 is a conceptual diagram of an image of the screen projection plane A observed along the course separation line CL on the course on which the racing car runs. In such an image, the vanishing point BP is drawn so as to be positioned substantially at the center (on the y axis) of the screen.

  Furthermore, as described above, the screen projection plane A is converted into the range of the viewport VP (cut out), drawn in the graphic memory 227, and displayed on the monitor 21.

  Therefore, the image displayed on the monitor 21 is conceptually shown in the lower left of FIG. 5 corresponding to the viewport VP, and (VX, VY) represents a predetermined bit position coordinate system of the monitor 21. ing.

  Here, in the normal screen shown in FIG. 5, since the coordinates of the center of the viewport VP coincide with the origin coordinates of the screen projection plane A, the vanishing point BP is monitored in the same manner as the position on the screen projection plane A. It will be located in the approximate center of 21.

  Such an image illustrated in FIG. 5 is before the start of the game in FIG. 4 and when it is not set to which player side the steering operation is valid, such as when an advertisement screen is displayed (step S11). , No), it is displayed as a normal display image.

  Next, in FIG. 4, when the game is started (step S11, Yes), the player determines which of the two players in line is the main driver, or if there is only one player. 21. An instruction for inputting an initial setting is made by using the instruction input means to determine whether to operate while sitting on the left or right relative position side. The CPU 222 determines the instruction input for the initial setting by the player (step S12).

  For example, an accelerator pedal is used as the instruction input means. An image prompting the user to select the main driver at the start of the game (an instruction to step on the accelerator pedal on the main driver side) is displayed, and the control means on the side with the accelerator pedal that was stepped on first is validated.

  As another embodiment, for example, in a shooting game other than a racing game, for example, there is a configuration including a gun controller provided on the left and right with respect to the monitor screen and a button for selecting which gun controller to use. Correspond.

  Here, it is assumed that it is determined that the instruction to use the player who sits side by side in front of the monitor 21 as the main driver is the player who sits on the left side toward the monitor 21. . The determined main driver is set in a register and stored (step S13).

  Next, the center of the viewport VP in the screen coordinate system is shifted, and a predetermined range corresponding to the viewport VP is moved corresponding to the set main driver side (step S30).

  That is, since the player sitting on the left side is the main driver, as shown in FIG. 6, the center coordinates of the viewport VP are shifted to the right side with respect to the origin of the screen coordinate system, and (x ′, y ′ ) Change to coordinates.

  At this time, the image drawn in the graphic memory 227 (step S5) is displayed on the monitor 21 as shown in the lower left of FIG. 6, and the vanishing point BP is deflected (shifted) to the left side of the screen. Understandable.

  As a result, the vanishing point BP can be seen substantially in front of the main driver sitting on the left side, that is, the direction of the traveling course coincides with the line-of-sight direction facing the front with respect to the monitor 21 of the player sitting on the left side. Thus, it is possible to eliminate a sense of incongruity in the operation.

  On the other hand, when the player located on the right side becomes the main driver and the maneuvering operation is enabled, as shown in FIG. Shift to the left and change to (x ″, y ″) coordinates.

  At this time, the image drawn in the graphic memory 227 (step S4) is displayed on the monitor 21 as shown in the lower left of FIG. 7, and the vanishing point BP is deflected (shifted) to the right side of the screen. Understandable.

  As a result, the vanishing point BP can be seen substantially in front of the main driver sitting on the right side, that is, the direction of the traveling course coincides with the line-of-sight direction facing the front with respect to the monitor 21 of the player sitting on the right side. Thus, it is possible to eliminate a sense of incongruity in the operation.

  Thus, in the present invention, display control is performed so that the vanishing point BP is deflected (shifted) in accordance with the position on the player side where the maneuvering operation is valid.

  Returning to the flow of FIG. 4, when a player change condition occurs (step S14, Yes), the process returns to step S12 in order to validate the operation of the changed player, and the processing from step 13 onwards is similarly performed. Done.

  In the above description of the embodiment, it has been described that the coordinate conversion is performed so that the viewpoint coordinates are shifted by a predetermined amount corresponding to the change of the main driver. However, in the application of this embodiment, the viewpoint coordinates are gradually shifted. It is also possible to follow. It is also possible to display the image so that the vanishing point BP is continuously deflected by performing the processing after step S13 based on the explanation of FIG. 4 explained above corresponding to each shift amount change. .

  Here, a specific example when the player change condition in step S14 occurs will be described below.

  FIG. 8 is a diagram illustrating an external front view of a game apparatus that performs a car race as an example. FIG. 9 is a view of a similar game device as viewed from above.

  A plurality of (four cars as an example) racing car cockpit models 11 to 14 are provided in parallel.

  Projector screens (monitors) 21 to 24 are displayed on the front surfaces of the cockpit models 11 to 14, respectively, on which a racing course in a virtual three-dimensional space formed from the viewpoint of the host vehicle is displayed as the program progresses. Furthermore, each of the cockpit models 11 to 14 is provided with coin insertion slots 31 to 34 necessary for participating in the game.

  A panel display device 4 and an image display device 5 for displaying a player (player) image or a game image adjacent to the panel display device 4 are arranged on the upper part of the game system as appropriate in accordance with the specifications of the system. Furthermore, left and right speakers 61 and 62 are provided.

  8 and 9, there is further shown a control unit 7 for comprehensively controlling the entire game system.

  Since the four cockpit models 11 to 14 have the same form, FIG. 10 shows a common cockpit model form.

  As an embodiment, two players (players) sit in a single cockpit model as a set, and handles (steering) 100A and 100B, accelerator pedals 101A and 101B as operating means provided for the players are provided. The brake pedals 102A and 102B are operated. Note that the shift lever 110 is operated and used in common for two players when a manual vehicle is used as a model. When an automatic vehicle is used as a model, other control buttons or the like can be provided instead of the shift lever 110.

  With such a configuration, the prior invention of Patent Document 1 is controlled so as to switch the effectiveness of the output of the operation means provided when a predetermined condition is satisfied as a change of a player. That is, the operation means output of only the player on the side to be changed is valid.

  Further, in FIG. 10, the cockpit model is provided with a wide-angle CCD camera 120 that can simultaneously image two players. The video signal imaged by the CCD camera 120 is displayed on the image display device 5 shown in FIG.

  The panel display device 4 provided adjacent to the image display device 5 displays game information corresponding to the progress of the game, for example, information such as ranking information during the race. Further, the panel display device 4 simultaneously displays a display relating the image displayed on the image display device 5 and the game information.

  FIG. 11 is a perspective view for facilitating understanding of the mechanism of one cockpit model shown corresponding to FIG. In addition, in order to show a vibration mechanism, the state which removed the rear cover is shown.

  In FIG. 11, two seats for giving a virtual feeling when driving a car race to the seats 103A and 103B on which two players sit are given tilt or vibration corresponding to the progress of the game. Cylinders 104A and 104B are provided.

  FIG. 13 is a diagram illustrating that the application of the present invention is not limited to a game device provided in one amusement facility. That is, a plurality of play facilities GS1, GS2,... GSn are connected via the network NW.

  The game device shown in FIG. 8 is arranged in each of a plurality of play facilities GS1, GS2,. The racing game is not limited to the four model devices shown in FIG. 8 and can be executed in a virtual racing space between a plurality of model devices connected via the network NW.

  In such a case, in order to control the whole, the game device in any one of the play facilities GS1 to GSn functions as a game master machine (server), and the game devices that are other clients are synchronously controlled.

  FIG. 13 is a functional block diagram corresponding to the configuration of FIG. 9, which is one game device placed in such amusement facilities GS <b> 2 to GSn. Since connection control between the game facilities GS2 to GSn is not directly related to the control in the present invention, communication connection with other game devices is not shown in FIG.

  Corresponding to the cockpit models 11 to 14, control circuit function units 201 to 204 having the same configuration are provided. The control circuit function units 201 to 204 are LAN-connected by the HUB 210. Each of the control circuit function units 201 to 204 has a game board 212 configured as shown in FIG. 1 for storing and executing a program.

  Each game board 212 in the cockpit models 11 to 14 is LAN-connected by a hub 210. One game board 212 in the cockpit models 11 to 14 becomes a master board, and game data is collected from the game board 212 which is a slave board of another cockpit model, and rank calculation is performed. Then, the calculation result is returned from the master board to the cockpit model game board as the slave board.

  Therefore, each game board 212 in the cockpit models 11 to 14 can always share data in the game system. Thereby, even when the master board goes down, the game board 212 of the cockpit model that was another slave board can easily be a master board.

  The input I / O board 213 detects movements of the accelerator pedals 101A and 101B, the brake pedals 102A and 102B, and the shift lever 110, receives corresponding signals, and sends them to the game board 212.

  Furthermore, it has an actuator control board 214, notifies the main control board 200 of the game state of each of the cockpit models 11 to 14, and moves dynamically according to the progress of the game in cooperation with the main control board 200. Actuators (cylinders 104A and 104B: FIG. 11) that give the player a feeling of driving an actual vehicle are controlled.

  The main control board 200 controls the video switch board 205 and the I / O board 504 of the panel display device 4. The main control board 200 and the video switch board 205 are included in the control unit 7 shown in FIG.

  The video switch board 205 inputs an image pickup signal of the CCD camera 120 provided in each of the cockpit models 11 to 14, is switched by the main control board 200, and sends a display signal to the image display device 5. Therefore, the video of the player imaged by the CCD camera 120 in any of the cockpit models 11 to 14 selected by the video switch board 205 is displayed on the image display device 5.

  Further, when a game image is displayed on the image display device 5, the main control board 200 selects a video signal sent from the actuator control board 214 and sends it to the image display device 5 through the video switch board 205.

  Further, the main control board 200 sends an information signal for an image displayed on the image display device 5 to the I / O board 500 of the panel display device 4.

  Based on the signal sent from the main control board 200, the I / O board 500 sends a lighting control signal to the light source 501 of the corresponding panel display device 4. Thereby, information display in which images displayed on the image display device 5 are associated with each other can be performed on the panel display device 4.

  FIG. 14 is a diagram illustrating the functions of the I / O board 213 and the actuator control board 214 that cooperate with the game board 212 shown in the configuration example of FIG.

  The accelerator 101A (101B) and the brake 102A (102B) are each configured to output an operation signal corresponding to the depression amount.

  The handle 100A (100B) is configured to output an operation signal of an amount corresponding to the operation angle. Further, the shift key 110 corresponding to the shift lever outputs an operation signal corresponding to the switching position.

  An operation signal based on the player's operation on these operation means is input to the I / O board 213. The I / O board 213 acquires a status signal from the game board 212, that is, information on which side of the two players is valid, and sends an operation signal on the valid side to the game board 212. Information about which side of the two players is valid is held in the system memory 223 during the game execution.

  Furthermore, the game board 212 sends information indicating which side of the two players is valid to the handle control switching board 131 and the actuator control board 214 provided along with the handle 100A (100B).

  The handle control switching board 131 sends a drive command to the motor drive board 130A (130B) on the handle side that is enabled based on the information sent from the game board 212 under a predetermined condition, and the motor to the handle 100A (100B). Rotate by applying rotational driving force. As a result, it is possible to give the player a virtual sensation of receiving an impact on the handle while the game is running.

  On the other hand, the actuator control board 214 sends a drive command to the right and left actuator control boards 114A (114B) according to a predetermined program based on the information sent from the game board 212 according to a predetermined program, and the cylinder 104A (104B). Control the vertical movement of the. As a result, as shown in FIG. 11, the driver seat 103A (103B) is given a pitching or rolling motion, and a virtual sense of receiving an impact on the vehicle body during the game running can be given.

  Here, the present invention is applied between the players sitting in the four racing car models shown in FIG. 8 or between the game devices of different game facilities GS1 to GSn through the network NW in FIG. It is not limited to assuming a racing car operated by another player as an opponent of the racing competition in.

  That is, in each of the racing models, the movement is controlled by the CPU 222 in accordance with the program, and the game can be advanced using the racing car displayed as an image as an opponent of the racing competition.

  Next, a description will be given of change control of a player according to the prior invention of Patent Document 1, which is the premise of the present invention, executed in the configuration of the above-described game device. Note that such change control is also commonly applied to the case where a racing car operated by another player as described above or a racing car controlled by the CPU 222 is used as an opponent.

  FIG. 15 and FIG. 16 are diagrams showing a change control flow of a player according to the prior invention described in Patent Document 1. Particularly, FIG. 15 is a flow from the start of the game to the end of the game, and FIG. 16 is an operation flow of the player (driver) change event process in FIG.

  15 and 16 are executed by controlling the CPU 222 by a program stored in the program data storage device 221 of the game board 212.

  In FIG. 15, when a game is started, event processing is always executed at a predetermined time interval, for example, once every frame (1/60 · sec).

  In the event processing, input (step S0) from the operating means (handle, accelerator, brake) is monitored, and image processing in the game according to the program and further drive processing to the actuator are performed (step S21). That is, the image processing corresponding to the increase / decrease of the speed of the racing car to be operated, the control of the traveling direction, etc. is executed.

  In such event processing, a driver replacement condition is detected. An example of the driver change condition is shown in FIG. In FIG. 17, the conditions indicated by ● are driver replacement conditions.

  As one of them, it is determined whether or not a branch point (point) position has been reached (step S22). In other words, when the change position distance (distance for adjusting the change position) has passed within a predetermined branch point on the course arranged during the race, it is determined that the change condition is met (step S22, YES).

  Further, as another driver replacement condition, it is determined that the moment of collision with another vehicle or a wall matches the replacement condition (YES in step S25).

  In the game image processing, the collision is determined when the coordinate position in the virtual three-dimensional space between the vehicle to be operated and the other vehicle or an opposing object such as a wall is in a predetermined relationship (for example, matching). Is determined to be a collision. As another collision determination method, for example, as shown in paragraph (0207,0028) of JP-A-9-325684, for collision determination provided to cover a racing car (race car) in a virtual space. (For example, a spherical ball or a box-shaped area) is stored in the storage means. And a control means can also determine the collision of a racing car by calculating whether this area | region overlaps the area | region which covers another racing car (whether there exists an intersection).

  If it is determined that the driver replacement condition is met, it is determined whether or not the replacement event is being activated (step S23, step S26), and when it is a new replacement event (step S23, step S26, NO). Then, a replacement event process is started (steps S24 and S27).

  Further, as shown in the example of the driver change condition in FIG. 17, not only the collision determination but also the impact state of the race car that is the operation target at that time (specifically, the moving direction and the moving speed of the racing car). The replacement process may be performed on the condition of

  The replacement event processing in steps S24 and S27 is common, and the contents of the replacement event processing are shown in the operation flow of FIG.

  In FIG. 16, it is determined whether the game mode is in effect (step S40), and if not in the game mode, the event process is closed (step S41). Here, the game mode means an actual game, that is, a state other than a goal or a game over.

  If it is in the game mode (step S40, YES), it is determined whether or not it is a notification process (step S42). If it is a notification process, a notification process is performed (step S43). A notice is given in advance during a predetermined period that a driver will be replaced by a notice process. This is because the advance notice makes it possible for a new player to take turns to get on the flow of the racing car and to make it easier to control, so that a grace period is formed before the change is made effective.

  When the notification period ends (step S44, YES), it is determined that it is a player's replacement process step (step S45, Yes), and the process proceeds to the start of the replacement process (step S46).

  The player replacement process is a process of switching between valid and invalid (or input switching) of the operation signal from the operation means corresponding to the player.

  When the player change process (step S46) is performed, the process proceeds to a standby process (step S47). The operation signal of the new player who has been replaced by the replacement process becomes valid, but a predetermined grace time is given to the new player who has been replaced by the standby process. That is, no new replacement event is generated within the grace period.

  This is because the player's response process immediately after the change cannot always catch up with the progress of the game. This is a process for protecting such a state.

  Therefore, even if the branch point is reached within the grace period (step S48, YES), the player change event process is terminated without generating a driver change event.

  When the standby time is over (step S49, YES), the event is closed (step S41).

  Further, when it is determined that the process is not the above notification process (step S42, NO), if it is a replacement process (step S45, YES), the process proceeds to a replacement process (step S46), and if it is not a replacement process (step S45, NO) ), And shifts to a standby process (step S47).

  Here, the above embodiment shows an example in which a player sits on a device simulating a car installed in a play facility and operates a handle or the like, but the application of the present invention is limited to a game device in such a play facility. Not.

  That is, for example, the present invention can also be applied to a home game machine as described in JP 2007-61271 A. As means for setting the position of the player, a plurality of controllers (operation means) in the above-mentioned Japanese Patent Application Laid-Open No. 2007-61271 are used.

  For example, a light emitting part provided in the vicinity of the display means or in one of the operation means, a light receiving part provided on the other side for receiving light from the light emitting part, and light receiving indicating a light receiving mode of the light receiving part Based on the data, it is possible to configure to detect a relative position of the operation means for which the operation signal is validated by the control means with respect to the display means.

  As a result, it is possible to detect which controller the detected light side corresponds to and to control the deflection of the extinction point by shifting the screen coordinate system in the same manner as described in the above embodiment. .
