Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a method for generating a game image using an image display device that performs display corresponding to a viewing angle, a game program for controlling execution of a game, and a game device for executing the same.
[0002]
[Prior art]
As a game device for executing a game by a plurality of players using an image display device, a type of “single monitor multi-game” below, in which a plurality of players surround a single image display device as shown in FIG. 2), a type in which a player operates the game simultaneously in each of a plurality of image display devices 101 to 102 as shown in FIG. 2 (hereinafter referred to as “multi-monitor multi-player type”). Called).
[0003]
In the “single monitor multiplayer type” game, as shown in FIG. 1A, a plurality of players (players) share a single image display device 100 and play a game together. In this example, in FIG. 1B, the objects (1) to (8) displayed on the image display device 100 can be viewed by all players.
[0004]
The advantage of the game with this type of game device is that each player can share the same image display device and execute the game, thereby obtaining a “sense of unity”. A single image display device can be surrounded and coordinated with each other or played against each other. On the other hand, the disadvantage is that in this game, each player sees the same screen of the image display device, and therefore all the information received from the display image is the same.
[0005]
In other words, since each other's information is shared, the displayed information is always passive. At the same time, the content of the game has the limitation that it is inevitably designed based on the condition that all the information received from the display image is the same. That is, it is not possible to realize a game characteristic in which a part of information that each player personally has is displayed on one shared image display device and a part of the information is not displayed.
[0006]
On the other hand, in the “multi-monitor multiplayer type” game, as shown in FIG. 2A, a plurality of players (players) are associated with different image display devices 101 and 102, respectively.
[0007]
The advantage of this game is that information known only to each player can be displayed on each image display device 101, 102, and the depth (complexity and fun of multiplexing display information) can be added to the game characteristics. That is. In the example shown in FIG. 2B, each player (player) faces a dedicated display device. Therefore, the player (player) A cannot see the objects (7) and (8) which are the pieces of the player (player) B. On the other hand, the player (player) B cannot see the objects (5) and (6) which are the pieces of the player (player) A.
[0008]
However, conversely, since the screens of different image display devices are seen, each player cannot directly face each other. Friends cannot face each other face-to-face, and players cannot collaborate together around one image display device. It is not possible to realize a game characteristic that a player who participates in a game or a gallery who is watching a game scenery around the user enjoys surrounding an image display device.
[0009]
[Problems to be solved by the invention]
As described above, the “single monitor multi player type” and “multi monitor multi player type” game devices realized in the prior art and the game execution method executed therein have conflicting advantages and disadvantages, respectively. ing.
[0010]
In other words, the advantage of using the conventional “single monitor multi-player” game device is that it can provide “a sense of unity of the place” by sharing an image display device with multiple players and galleries. It is.
[0011]
The advantage of using the conventional “multi-monitor, multi-player” game device is that the game characteristics (complexity, fun, and so on) are obtained by giving different information to each player and gallery. )) ”Can be provided.
[0012]
At present, a game apparatus and a game execution method that simultaneously realize these two advantages have not been proposed. In addition, since the “multi-monitor multi-player type” game has to install a plurality of display devices, a large installation area is also a problem.
[0013]
Here, a multi-image display device using a parallax barrier and having different images that can be observed depending on the viewing angle is proposed as one image display device that allows multiple viewers to see different display information. (See Patent Document 1).
[0014]
[Patent Document 1]
JP 2000-36927 A
Patent Document 1 discloses an application in which a car navigation image and a TV image can be independently observed by first and second observers, respectively.
[0015]
That is, the video signals from the two information sources, the car navigation system and the TV receiver, are supplied to a plurality of video display devices and are displayed so as to be observable only at a predetermined viewing angle.
[0016]
In view of the conventional background art, an object of the present invention is to provide a method for generating a game image and an execution of a game using an image display device that performs display corresponding to a viewing angle for a plurality of players and galleries. It is an object of the present invention to provide a game program to be controlled and a game device that executes the game program. Thus, the present invention provides “a sense of unity of the place” by sharing the image display device, and gives different information to each player and gallery. , Interesting)).

DETAILED DESCRIPTION OF THE INVENTION
FIG. 3 is a block diagram illustrating a configuration example of a game apparatus in which a game program for controlling execution of a game using an image display apparatus that performs display corresponding to a viewing angle according to the present invention is executed.
[0028]
In FIG. 3, the case where the program according to the present invention, game data, etc. are recorded in the external storage device 2 and the program is executed by the CPU 10 as the control means will be described.
[0029]
Functional devices such as a CPU 10, a RAM 11, a ROM 12, a video RAM (VRAM) 13, a bridge IC 14, an image generation IC 15, a sound generation IC 16, a communication control IC 17, and an I / O control IC 18 are mounted on the main board 1 of the main body apparatus. Yes. These functional parts are connected to each other via a system bus 19 on the main board 1 so as to be able to input and output data.
[0030]
The CPU 10 activates the game device by the activation program recorded in the ROM 12 on the main board 1.
[0031]
As the external storage device 2, a replaceable information storage medium such as a CD-ROM, a DVD-ROM, a hard disk, a magnetic card, a FLASH memory, a game cassette, or the like is used. The information storage medium stores a game program according to the present invention, image data for expressing an object (display object), sound data, game data, and the like.
[0032]
The CPU 10 controls the bridge IC 14 to read and develop game programs and data from the external storage device 2 to the RAM 11 on the main board 1.
[0033]
The game operation input / output device 3 is a device for inputting / outputting control data to / from the game device in response to an operation performed by the game player as the game progresses. Therefore, the CPU 10 receives game control data corresponding to an operation by the player's input / output device 3 through the I / O control IC 18.
[0034]
The CPU 10 can also receive game control data input from the communication port 4 from an external system (not shown) through the communication control IC 17.
[0035]
The CPU 10 further outputs background music and sound effects constituting the game to the speaker 5 through the sound generation IC 16 based on information recorded in the RAM 11 and the ROM 12.
[0036]
In accordance with the program of the present invention, the CPU 10 also transmits data stored in the RAM 11, data stored in the ROM 12, game control data from the input / output device 3 for game operation, and the communication port 4 from an external system. The input game control data is processed to control the game device. That is, the CPU 10 individually generates a display image based on the data corresponding to each viewing angle direction of the image display device 6 that performs display corresponding to the viewing angle through the image generation IC 15.
[0037]
In the present invention, the CPU 10 and the image generation IC 15 are defined as control means. The image generation IC 15 mainly has a geometry function unit and a rendering function unit.
[0038]
The geometry function unit converts coordinate data in a virtual three-dimensional space of an object composed of a plurality of polygons read from the RAM 11 by the CPU 10 according to a program into camera coordinate system data corresponding to a predetermined viewing angle. This is a function for perspective transformation to the screen coordinate system.
[0039]
The rendering function unit has a function of performing texture processing for attaching a texture to the perspective-converted polygon, generating image data corresponding to a predetermined viewing angle, and rendering the image data in the video RAM 13 which is a video memory.
[0040]
The rendering function unit further synthesizes the image data corresponding to the predetermined viewing angle drawn in the video RAM 13 in accordance with the specifications of the image display device that performs display corresponding to the viewing angle, and sends it to the image display device 6 for display. Let
[0041]
Here, the image display device 6 necessary for executing the game program of the present invention will be considered.
[0042]
In general, an image display device such as a television or a monitor presents a displayed image as the same information regardless of the angle with respect to the display screen. Therefore, in order to present different information to each person who is watching the display screen, the same number of image display devices as the number of people who are watching are necessary.
[0043]
On the other hand, in recent years, special image display devices for displaying stereoscopic images with the naked eye have been developed. For example, there is a stereoscopic image display apparatus using the technique described in FIG. 6.18 of the book “3D video basics” published by Ohmsha, Ltd. June 5, 1995 (P145-150).
[0044]
Such an image display device described in FIG. 6.18 of the non-patent document is equipped with a lenticular lens, a microlens, or a special prism for each pixel of the image display device, bent in the traveling direction of light emitted from the pixel, and observed. It is possible to show separate images to the right eye and the left eye of the person. The object displayed by giving a parallax image to the observer is shown in three dimensions.
[0045]
A multi-view stereoscopic display device using a parallax barrier has also been realized by a method different from the above. For example, in the technique shown in FIG. 6.15 of the above non-patent document or Patent No. 3096613, the image display device is equipped with a parallax barrier made of a large number of fine slits, and the direction in which each pixel of the image display device can be seen is displayed. Limited.
[0046]
FIG. 4 is a diagram schematically showing an image display device 6 using this parallax barrier. In FIG. 4, the pixels of the display image formed on the display panel 6-1 are arranged at the pixel pitch P. A parallax barrier 6-2 is disposed with a gap S in front of the display panel 6-1.
[0047]
The parallax barrier 6-2 has a plurality of openings arranged at an opening pitch Bo and having an opening width Bh.
[0048]
Further, an observer at the distance E (interocular distance 61) between the left and right eyes at a position (appropriate viewing distance 60) away from the display panel 6-1 by a predetermined distance D passes through the parallax barrier 6-2. The display image formed is observed. At this time, a stereoscopic image can be observed when the display image formed on the display panel 6-1 is an image for the left and right eyes based on the parallax angle of the left and right eyes.
[0049]
The above is an example of a parallax barrier type display device using the parallax barrier 6-2, but for example, the same applies to a lenticular type display device using a lenticular lens disclosed in JP-A-9-46622. is there.
[0050]
Here, the predetermined distance D is a unique distance at which each image is best separated, and this is referred to as an appropriate viewing distance 60. When the observer observes away from the appropriate viewing distance 60, the display image appears to be mixed. At this time, the observer cannot see the display image in three dimensions, but can recognize display information of a plurality of display images.
[0051]
On the other hand, when the observer moves his / her eyes to the left and right in parallel with the display panel 6-1, the viewing angle at which the display image formed on the display panel 6-1 can be observed through the opening of the parallax barrier 6-2 changes. Therefore, the display image that can be observed also changes in each display direction number M. In FIG. 4, the number of display directions is M = 4, and different images can be observed corresponding to the viewing angle positions a, b, c, and d.
[0052]
Furthermore, the image display apparatus 6 shown in FIG. 4 has a distance E where one video can be seen, and this is referred to as an interocular distance 61. Since the image display device was originally developed to show a stereoscopic image (see Patent No. 3096613), the interocular distance 61 is set to 65 mm which is the width of a general right eye and left eye of a person. Designed to.
[0053]
As an example, when used as an image display device 6 suitable for execution of the game program of the present invention, the interocular distance 61 of the stereoscopic display device is increased to a distance that can accommodate at least a human head, approximately 22 cm. Can be manufactured. At this time, as the image display device 6 used in the game device, the appropriate viewing distance 60 is practically set to about 1.5 m.
[0054]
The feature of the present invention is to set the following unprecedented requirements by utilizing the characteristics of the image display device 6 described above, and to correspond to the game program. That is,
A: Unlike a multi-view display device, it is not necessary to display different images (images) in all display direction numbers m.
[0055]
B: Display direction number m ≧ viewing angle separation direction number n, and the division allocation is changed according to the game content.
[0056]
C: When the number m of display directions> the number n of viewing angle separations, the maximum number of renderings may be n (the number required for the game).
[0057]
FIG. 5 shows a concept of a game executed by the program according to the present invention in the game device using the image display device 6 described in FIG.
[0058]
For example, consider the case where the number of display directions m is three in FIG.
[0059]
Since a display screen that is visible only to each player is required in the battle game, first, one display direction is assigned to each of the viewers A and B who are players. Furthermore, the remaining one display direction is assigned to the display of the image observed by the observer C, which is a gallery other than the observers A and B, and the display is performed.
[0060]
In FIG. 5, when the viewer C who is the gallery is not assigned a specific display direction and is observed away from the appropriate viewing distance 60 of the image display device 6, the viewers A and B who are players are It is possible to observe all the displayed images.
[0061]
FIG. 6 shows a picture of an example screen of a game apparatus that executes the program of the present invention using the image display apparatus. FIG. 6 shows an example in which the parallax barrier type multi-view stereoscopic display device described above with reference to FIG. 5 is improved and an original image display device in which the interocular distance 61 is increased to 22 cm.
[0062]
6 (FIGS. 6A, 6B, and 6C) are photographs of the same image display device 6 taken from three positions 6A, 6B, and 6C. The image display device 6 is photographed by moving the photographing position from the end position to the front position in the order of FIGS. 6A, 6B, and 6C. A “chair” object is only displayed at the end of the arrows 6A1 and 6A2 in the photograph at the position 6A.
[0063]
On the other hand, it can be seen that the “ghost” object is displayed on the “chair” at the tip of the arrow 6B2 in the photograph at the position 6B and the arrow 6C1 in the photograph at the position 6C. Conversely, the “ghost” object is not displayed at the tip of the arrow 6B1 in the photograph at the position 6B and the arrow 6C2 in the photograph at the position 6C. In this way, by changing the viewing position with respect to the image display device (changing the viewing angle), the display object may or may not be visible.
[0064]
It is clear from the above description and examples that the image display device 6 necessary for implementing the present invention can be easily realized by using a multi-view stereoscopic display device developed in recent years. .
[0065]
In addition, the use of the technology of the parallax barrier multi-view stereoscopic display device as an implementation method of the image display device 6 required in the present invention is only an example of the implementation method, and can be implemented by other technologies. It is.
[0066]
It is not a necessary condition of the image display device 6 of the present invention to make the display object appear three-dimensional. In order to make the present invention applicable as the image display device 6, any image display device that performs display corresponding to at least a viewing angle may be used.
[0067]
That is, it is required that display information that can be observed by the player is determined by the positional relationship between the image display device 6 and the player, and that each player can obtain different display information on one image display device. . Any image display device that can satisfy this requirement may be used.
[0068]
The operation of the game apparatus configuration shown in FIG. 3 will be further described. The image display device 6 operates in synchronization with drawing switching. In a normal game, the operating frequency is 60 Hz, and 60 screens are updated per second. The time from switching from one screen to the next is called one frame, and is the processing unit of the game device with respect to time.
[0069]
7 and 8 are operation flowcharts for explaining a series of processing performed in one frame.
[0070]
When the frame is started, the CPU 10 receives operation information (input data) of the player participating in the game from the game operation input / output device 3 through the I / O control IC 18 (processing step P1). Those pieces of information are sequentially stored in the RAM 11 on the main substrate 1 (processing step P2). This process is performed for all the participating players (processing step P3).
[0071]
Next, the CPU 10 performs a process of determining whether or not the key object in the game can be seen from each separation direction (predetermined viewing angle direction) from the input data and the game data (processing step P4).
[0072]
Here, the game data is system data for determining a game device, and the game program of the present invention determines the contents to be executed based on, for example, the following system data.
[Number of players data: pl (= 0, 1, 2,..., L,..., P−1)]
The number of players participating in the game.
[Number of display direction data: m]
The number of display directions of the image display device 6 that can project different images in each direction. It is determined by the specifications of the image display device.
[Separation number direction number data: ni (= 0, 1, 2,..., I,..., N−1)]
The number of separation directions actually used in the game. The number is less than or equal to the display direction number data m and is determined by the game content.
[Game end flag: e]
When a certain player (s) satisfies the victory condition of the game and the game program disclosed in the present invention determines the end of the game, the game program sets a game end flag and the game ends.
[Cooperation-Battle Flag: a]
Flag data indicating whether the player cooperates or fights.
[Movement-still flag: b]
Flag data indicating whether the player moves or stops.
[0073]
Returning to FIG. 7, the process P4 is repeated for one key object by the number of separations in the display direction, and when the process is completed for all separation directions (Yes in the process step P5), The key object management data corresponding to the key object is updated (processing step P6). This series of processing is repeated for all key objects (processing step P7).
[0074]
Next, the CPU 10 renders the display screen in each separation direction via the image generation IC 15 (processing step P8: FIG. 8).
[0075]
Here, the rendering processing in the image generation IC 15 needs to repeatedly perform rendering for the number of separation directions. For rendering the display screen for each separation direction, the rendering is executed by determining whether a certain key object should be drawn in the separation direction according to the key object management data.
[0076]
For example, in the case of display images from the first direction to the fourth direction corresponding to the viewing angles shown in FIGS. 9 to 12, a key object (enemy monster object) exists in the location 2 during the game. Is visible from the third direction, but not visible from the other first, second, and fourth directions. Therefore, this key object (enemy monster object) is not drawn during display screen rendering in the first direction, second direction, and fourth direction, but is drawn during display screen rendering in the third direction.
[0077]
The background object is an object that can be viewed from all the separation directions, and management data is not necessary. The background object is always drawn when the display screen is rendered in each direction (processing step P9). Thereby, the display screen in the relevant separation direction is completed (processing step P10).
[0078]
Next, when rendering of the display screen for all the separation directions is completed (processing step P11, Yes), the CPU 10 instructs the image generation IC 15 to synthesize the display screen according to the specifications of the display device that performs display corresponding to the viewing angle. (Processing Step P12). FIG. 13 is an example of a display image obtained by synthesizing the display images in the first to fourth directions of FIGS. 9 to 12.
[0079]
As shown in FIG. 13, one completed display screen is output to the image display device 6 that performs display corresponding to the viewing angle, and the frame ends.
[0080]
Hereinafter, an example in which the game program of the present invention using the image display device described above is realized in the game device configuration shown in FIG. 3 will be described.
[0081]
FIG. 14 is a flowchart showing the flow of processing in the game apparatus 1 that executes the game program of the present invention.
[0082]
As a major flow, there are a step S1 for determining the contents of the game process and a step S2 for performing the game process corresponding to the determined contents of the game process.
[0083]
In step S1, first, a screen for confirming the number of players participating is displayed on the screen of the image display device 6 in order to confirm how many players play the game (processing step S1-P1).
[0084]
Thereafter, the player inputs the number of participants p to the game device 1 using the input device 3 for game operation (processing step S1-P2). Similarly, when a game is played by a plurality of players, a screen is displayed on the image display device 6 for selecting whether to clear the game in cooperation with each other or to play each other (processing steps S1-P3), The player inputs the cooperation / match flag a to the game device 1 using the input device 3 for game operation (processing steps S1-P4).
[0085]
Similarly, when playing a game with a plurality of players, a screen for selecting whether the players play the game while moving relative to each other on the display screen of the game device or whether to play the game at the same position without moving. Displayed (processing step S1-P5), and the player uses the input device 3 for game operation to input the still / moving flag b to the game device (processing step S1-P6).
[0086]
The game apparatus 1 can also cause the player to select system data other than the above in accordance with the game content. The game program of the present invention determines the game processing contents based on the system data (processing steps S1-P7).
[0087]
The system data includes parameters such as the display direction number m of the image display device 6 and the game separation direction number n. The following explanation is supplemented for these system management data.
[0088]
The number m of display directions of the image display device 6 is determined in advance according to the specifications of the image display device 6 mounted on the game device 1 and is a value unique to the game device 1. The display direction cannot be increased beyond this display direction number m.
[0089]
As described above, the multi-view stereoscopic device according to the prior art uses all the display direction numbers m by allocating all the right-eye images and left-eye images alternately.
[0090]
In the program of the present invention, the number m of display directions is not allocated to the right-eye video and the left-eye video so as to be used in the multi-view stereoscopic display device. According to the control, the display direction number m is controlled to be allocated. Adjacent display directions do not necessarily have to be a right-eye video and a left-eye video.
[0091]
For example, consider the case of a game where the number of players is two and the game is a match-type game that is played by the player. Consider the case where the number of display directions of the image display device 6 is 4 as described above with reference to FIGS.
[0092]
Since a display screen that can be seen only by each player is required in a competitive game, first, one display direction is assigned to each player. The remaining two display directions are assigned to display directions for the gallery.
[0093]
Since the display screen for the gallery may have the same content, even if the number of display directions of the image display device is four, the number of times that the game program renders may be three.
[0094]
As described above with reference to FIGS. 7 and 8, the display image is rendered by the number n of the division directions. Unlike the multi-view stereoscopic device, it is not always necessary to use the game separation direction number n for all display direction numbers m.
[0095]
When the processing content of the game is determined in the processing of step S1, the progress of the game is actually started.
[0096]
The game program performs a game process according to operation information on the player's input device 6 (processing step S2-P1). During game processing, the game program sets a game end flag and ends the game when the game ends (processing step S2-P2, Yes), such as when a player satisfies the game victory condition.
[0097]
Next, the content of the game process (processing step S2-P1) will be described based on an example.
[0098]
The game apparatus 1 renders display images for each separation direction from the operation information from the player's input device 3 and the progress of the game according to the program, and synthesizes them into a single display image to be displayed on the image display apparatus 6. Output.
[0099]
At this time, the game program processes whether the key objects constituting the game scene are visible or not visible from each separation direction based on the player's operation information and the progress of the game, and updates the key object management data kmj.
[0100]
Depending on what kind of game is realized, the process of determining in which separation direction it is visible or invisible varies, but an example of this is shown in FIG. 15 and FIG. 16 shows the visible / invisible determination. This will be described with reference to a processing algorithm diagram.
[0101]
In the key object management processing diagram shown in FIG. 15, the game situation (application time tm, key object position kpj, key object status ksj, player operation information cl, background object position bpr, event occurrence time during game progress) It is determined whether the j-th key object koj that is currently processed is visible or not visible from the i-th separation direction ni that is currently being processed. To process.
[0102]
According to the processing result of the determination processing algorithm 100, the game program updates the value of the key object management data kmj by the CPU 10. As shown in the operation flow of FIGS. 7 and 8, this process is performed for every key object in every separation direction for every key object.
[0103]
In FIG. 15 (key object management processing diagram) and FIG. 16 (visible / invisible determination processing algorithm diagram), the following four factors are taken as examples of factors constituting the game situation in progress as an example. Explained.
[0104]
First, consider a case where a player plays a gun shooting game as an embodiment. The gun shooting game is a game in which a key object appearing on the screen is used as an input device 3 and a handgun controller is used to aim and shoot.
[0105]
The processing requirements in the gun shooting game of FIG. 16 are as follows. [1] Relationship between application time tm and event occurrence time Itm (see step S13 in FIG. 16)
When application time tm> event occurrence time Itm, the key object can be seen from all separation directions.
[2] Key object position kpj (see step S14 in FIG. 16)
When the position of the key object kpj ≦ the background object bo0 (bor: r = 0) region bp0, the key object is visible from the even-numbered separation direction and not visible from the odd-numbered separation direction.
[0106]
When key object position kpj> background object bo0 area bp0,
The key object is not visible from the even-numbered separation direction and is visible from the odd-numbered separation direction.
[3] Status ksj of the key object (see step S11 in FIG. 16)
When the key object is alive, ksj = 1, and when it is dead, ksj = 0. When the key object status ksj = 0, the key object is visible from all separation directions.
[4] Player operation information cl (see step S12 in FIG. 16)
When a player shoots a key object with a handgun type controller, the operation information cl is information indicating whether or not the object has been hit.
[5] Background object position data bpr
Indicates the area of the background object bor.
[0107]
When the key object condition data is read (step S10), when the key object is located in the background object bo0 area of the screen (Yes in step S14), the key object is visible from the even-numbered separation direction. (Step S19) The key object management data that is not visible from the odd-numbered separation direction is updated (Step S16). Conversely, when the key object is located outside the bo0 area (No in step S14), the key object management data is updated so that the key object is not visible from the even-numbered separation direction and is visible from the odd-numbered separation direction. (Steps S16 and S19).
[0108]
The key object status ksj is 1 when the key object is alive, and is 0 when the player is shot dead with a gun. When the key object is in a dead state, the key object management data is updated so that it can be seen from all separation directions regardless of whether the position of the key object is inside or outside the bo0 area (steps S11 and S19).
[0109]
When the game application time tm has passed the event occurrence time Itm, it will be easy to clear the game from all separation directions regardless of whether the position of the key object is inside or outside the background object bo0 area. Assume that it is visible (steps S13 and S19).
[0110]
FIG. 17, FIG. 18 and FIG. 19 are diagrams showing an embodiment in the case of playing a game using an image display device capable of displaying different images (corresponding to viewing angles) in each direction by one player. It is. FIG. 17 is a view of the positional relationship between the image display device 6 and the player as viewed from above. FIG. 18 shows an example of an image that can be observed in relation to the position of the player (FIG. 18a is image 1 and FIG. 18b is image 3). FIG. 19 is an operation flow of the game of FIG.
[0111]
Here, as an example, a case where a player A plays a gun shooting game is considered.
[0112]
In the conventional gun shooting game, the game is cleared and the game progresses by defeating the displayed enemy object as soon as possible without being attacked by the enemy. If attacked by the enemy, the life point of the player A is reduced. When player A has no life points, the game is over.
[0113]
By applying the present invention, it is possible to add a completely new game characteristic that has not existed before by using an image display device capable of projecting different images in each direction.
[0114]
As shown in FIG. 17, it is assumed that the enemy object α is visible when the player A stands at the position 6A (see FIG. 18a). At this time, the player A can kill the enemy object α with a gun (FIG. 19, P20). However, it is assumed that the enemy object β is approaching the player A together with the enemy object α during the game. From the position of the player A, the enemy object β is hidden behind the obstacle γ and cannot be seen (FIG. 19, P21).
[0115]
Therefore, the player A cannot recognize the approach of the enemy object β. The player A can find the enemy object β for the first time by moving the place to the position of the position 6C (see FIG. 18b, FIG. 19, P22).
[0116]
Thus, if the player A does not change the position with respect to the image display device 6, information necessary for the progress of the game cannot be read from the display screen. Such a change in the video is a game characteristic obtained by the present invention.
[0117]
In the conventional gun shooting game, the player can clear the game by always slaughtering enemy objects that are always displayed on the screen as soon as possible without changing the standing position in front of the image display device.
[0118]
According to the present invention, it is possible to add game characteristics as described above, and as a result, the player A defeats the enemy while moving the position to the positions 6A, 6B, and 6C shown in FIG. It has to go (FIG. 19, P23-1 to P23-3). The player A can be provided with a game that requires more momentum than a conventional game.
[0119]
Since you can see all the progress of the game from the gallery, you can also join the game by telling player A "I'm coming from the right" and "The left is dangerous".
[0120]
In a conventional game, there is a game in which the position of the player's head is detected using a head tracking device and the display content of the image display device is changed. Even in such a game, it is possible to realize the game characteristics of the gun shooting game described above as an example.
[0121]
However, in the case of the present invention, an extra detection device such as a head tracking device is not necessary. In addition, in the case of the present invention, since the gallery can add a game property that it is possible to see the whole progress of the game, it is easy for the game execution method to which the present invention is applied to be more effective than the game by the conventional program. Can understand.
[0122]
20, FIG. 21 and FIG. 22 are diagrams showing an embodiment in the case of playing a game using an image display device in which two or more players can display different videos in each viewing angle direction. FIG. 20 is a view of the positional relationship between the image display device 6 and the players A and B viewed from above. FIG. 21 shows an example of an image that can be observed in relation to the positions of the players A and B (FIG. 21a is image 1 and FIG. 21b is image 3). FIG. 22 is an operation flow of the game of FIG.
[0123]
As an example, a case where two players A and B cooperate with each other to execute a puzzle game is shown. As shown in FIG. 21, a large number of objects with different sizes, shapes, and colors, numbered in order from {1}, are displayed on the entire display screen.
[0124]
There is a rule that a player must select objects in ascending order of numbers. The game is cleared by selecting the object with the last number (the largest number). It is a puzzle game where two players cooperate to select an object and compete for a short time to clear.
[0125]
Only the video 1 can be seen at the position of the player A shown in FIG. Also, only the video 3 can be seen at the position of the player B. In video 1, objects (1), (2), (3), (4), and (7) shown in FIG. 21a are displayed. In the image 3, objects (1), (2), (4), (5), (6), and (7) shown in FIG. 21b are displayed.
[0126]
Each player must cooperate in order from the small numbered object (1) to the last (7) object. Since the objects {circle around (1)} and {circle around (2)} can be seen from both the players A and B, the player who has noticed the object early among the players A and B may select the object. The flow so far is a conventional cooperative puzzle game.
[0127]
Next, the object (3) must be selected, but since only the player A can see, the player B cannot select. Until the player A finishes selecting the object (3) (processing step P11, Yes), the player B cannot select the next object (4). Further, until the player B notices that the object (3) does not exist on his / her display screen, the player B is driven into a situation of continuously searching for the object (3) that does not exist.
[0128]
Thus, the viewing angle changes depending on the position of the player A and the player B with respect to the image display device, and the information received from the display device is different between the players A and B. As shown in FIGS. 21a and 21b, the objects (1), (2), (4), and (7) are information shared by the players A and B, and the object (3) is information that only the player A can know. Yes (FIGS. 21a and 22A), the objects (5) and (6) are information that only the player B knows (FIGS. 21b and 22B).
[0129]
In this way, it is possible to partially display information common to a plurality of players, or partially display information unique to each player, at an arbitrary position on one image display device. There can be no new gameplay added.
[0130]
By combining information that can be seen by one player but not seen by another player and information that can be seen by all players on a single image display device, an unprecedented game characteristic is added. It is possible.
[0131]
Even in this embodiment, the gallery viewed from a distance can see all of the objects (1) to (7).
[0132]
Here, the image display device 6 is not limited to standing, and can be used in a table-type housing that is laid horizontally. In this case, since it can be handled as a table with the image display device 6, it can also be installed as a simple game device in a store that conducts customer service such as a coffee shop or a sushi bar.
[0133]
As an example, FIGS. 23 to 25 show a case where two players A and B play against each other and execute a shooting game.
[0134]
Unlike traditional “multi-monitor multi-player” housings, competitive players can see each other's faces. The gallery can also overlook the entire monitor and recognize the whole progress of the game. In the battle case as shown in FIG. 2, the gallery cannot overlook the whole.
[0135]
FIG. 23 is a view of the positional relationship between the image display device 6 and the players A and B as viewed from above. FIG. 24 shows an example of an image that can be observed in relation to the positions of the players A and B (FIG. 23a is image 1 and FIG. 23b is image 3). FIG. 25 is an operation flow of a game according to one embodiment.
[0136]
There are display objects (1) to (8) on the display screen. Object (1) is the mother ship of player A, and object (2) is the mother ship of player B. Players who destroy each other's mother ship quickly become winners. Obstacles of objects (3) and (4) are displayed on the display screen. These objects (1) to (4) are background objects that can be seen by both of two players A and B (information display common to the players). Each player can make an object of a stealth fighter that can't be seen by an opponent player.
[0137]
Display objects {circle around (5)} and {circle around (6)} in FIG. 23 are stealth fighters to be operated by the player A and can be seen by the player A, but cannot be seen by the player B (FIG. 24a). . Also, the display objects (7) and (8) in FIG. 23 are stealth fighters to be operated by the player B and can be seen from the player B, but cannot be seen from the player A (FIG. 23). 24b).
[0138]
The displayed objects (5) to (8) are key objects. Each player can fire a lighting bullet from a mother ship within a limited range. If player A's stealth fighter is near the point where player B fired a light bullet, player B can temporarily see player A's stealth fighter that should not be visible. (FIG. 25, A).
[0139]
On the other hand, for the player A to win, the player A is operated so as not to disclose the information of the player A (FIG. 25, B). In this way, depending on the operation of the player B, it is possible to add a game characteristic in which the player A's stealth fighter can be seen or cannot be seen.
[0140]
Each player must execute the game while expecting the operation of the opponent player. An unprecedented game is provided on one image display device 6 by mixing information that can be seen by one player but not by another player and information that can be seen by all players. It is possible.
[0141]
In addition, it is possible to provide an unprecedented game characteristic by changing the state of information to information in which invisible information is temporarily visible depending on each player's operation.
Even in this embodiment, the gallery viewed from a distance can see all of the objects (1) to (8).
[0142]
The same can be applied to the battle-type simulation. In a simulation game with an emphasis on strategy, the formation, supply base, supply route, etc. by the player's possession pieces are information that the opponent player does not want to know.
[0143]
In order to realize such a situation, a game device is required in which such information is not visible to the opponent player but is visible to the player. In the initial stage of the game, the player assumes a secret base of the opponent player from the topography of the map of the simulation game, and plans a strategy that does not know whether it is correct. Also, taking into account the case where the assumption is wrong, it is necessary to prepare an escaper in advance.
[0144]
And while playing the game, judging from the opponent's player's strength distribution situation, he will change his strategy as needed. Such a deep simulation game cannot be realized with a conventional monitor that displays only one display information.
[0145]
In the case of such a game, when the battle by the game starts, the participating players have the least amount of opponent information, and the opponent information is gradually displayed as the game progresses. As can be seen from the previous shooting game examples and simulation game examples, the game is started from a state where there is little information to be shared with each other in the initial stage, and the information of the opponent player is gradually disclosed depending on how each player operates. As a result, more information is shared with each other. Based on the information that gradually increases, each player is required to modify the way of operation and strategy. Here, game characteristics not found in conventional games can be realized by using only one image display device.
[0146]
Conventionally, there are card games such as playing cards and magic the gathering, and games using a hand such as mahjong. These games have game characteristics in which the player's hand cannot be shown to the opponent player. Usually, if these games are to be realized as games using a display device, the same number of display devices as the number of players are required.
[0147]
When the present invention is applied, such a game can be realized with one image display device. Card games and mahjong games are handled on the game using a very large number of cards and tiles as a hand. The diversity of hand combinations is the essence of the fun of the game.
[0148]
However, due to the complexity of the combination, beginners are hesitant to participate in this game. In card games such as Magic the Gathering, when beginners start playing a game, it may not be clear how to handle the combination of the cards.
[0149]
These games are played with each other facing each other, but it is preferable that the game is advanced with an invisible referee called a computer between the player and the player in terms of reducing the burden on the novice player.
[0150]
An example is shown in FIG. Gamer A can see video 1. As shown in FIG. 26a, the picture 1 is an image in which the picture of the player's hand can be seen but the opponent player B's hand is turned down and cannot be seen.
[0151]
In addition, the player B can see the video 3. As shown in FIG. 26b, the image 3 is an image in which the picture of the player's hand can be seen but the opponent player A's hand is turned down and cannot be seen. In addition, in the video 1 that can only be viewed by the player A, an explanatory text (1) and a note (2) on A's hand are displayed. Also, in video 3 that can only be viewed by player B, advice (3) for B's hand is displayed.
[0152]
As described above, according to the present invention, it is possible to execute a game while facing each other using one image display device, and it is possible to display help display information (user auxiliary information) that is invisible to the opponent.
[0153]
【The invention's effect】
As described above, according to the drawings, the present invention provides a game program for controlling the execution of a game using the image display device that performs display corresponding to the viewing angle, and a game device for executing the same. . By sharing the image display device, it provides “a sense of unity of the place” and gives different information to each player and gallery, so that “gameability (complexity, fun) by multiplexing display information” Can be provided
