The game device realizes a game in which the content of the battle is that the player or the like attacks or receives an attack depending on the degree of contact between the enemy character on the game screen and the shadow of the player or the direction of the enemy character. can do. And since the shadow of a player etc. is input and it is displayed on an output screen simultaneously, the player can acquire the effect that a sense of unity with a game world increases.
Further, since the shape of the player or the like that creates the shadow is not limited (the player may have a tool), the player's own body shape, clothes, and belongings can be reflected in the game processing.
In addition, by adjusting the distance and installation between the screen and the light projecting means, the size of the shadow and the position where the shadow can be made can be changed even if the player stands at the same position on the stage. Features for each game device can be extracted.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view showing an appearance of a game device using a projected shadow according to the present invention.
A translucent screen 1 is erected vertically. The screen 1 has a dimension “a” higher than the height of the player, and the horizontal dimension “b” is made to have a ratio of 16: 9 to the height dimension “a”. A stage 9 having a horizontal dimension b and a vertical dimension c is provided in front of the screen 1. Further, in order to make a shadow of the player 3 standing on the stage 9, a light source 8 as a light projecting unit is provided at a position away from the stage 9 by a predetermined distance. The vertical dimension c of the stage 9 is related to the installation position of the light source 8 so that a shadow that does not protrude from the screen 1 can be produced even when the player is farthest from the screen 1. Moreover, the distance of the screen 1 can be adjusted within the installation distance of the above conditions (not shown, performed by an administrator). Thereby, even if it is a game device of the same content, by changing the installation distance of the light source 8, a game device can have individuality for every store, such as a game center.

The player 3 can move closer to the screen 1 on the stage 9 (the shadow becomes smaller), move away (the shadow becomes larger), and can move to the full horizontal dimension b. It is also possible to sit down or lie down. You can also jump and jump up, but the time to jump and display the shadow formed at the top of the screen is instantaneous. As will be described later, in order for a shadow to generate an effect as an input, it is necessary to stop at that position for at least a predetermined time. It does not occur.
When the player goes off the stage, the shadow goes off the screen, so that the game is subjected to a certain amount of damage.

A rear-type projector 7 is installed behind the screen 1 and projects a game screen on the screen 1 based on a command from the game apparatus 2. Further, a scanner 6 such as a CCD camera is installed above the position of the light source 8. The scanner 6 scans the entire screen 1 at a predetermined time interval (for example, 30 frames) and captures an image displayed on the Staline 1. The scanner 6 is connected to the game apparatus 2 together with the light source 8. The game apparatus 2 turns on the light source 8 at the start of the game, and further sends an image capture timing command to the scanner 6.
As an example of the game screen, an enemy character (frog face) 5 is displayed on the screen 1 in the upper right corner of the screen 1, and a shadow 4 of the player 3 is projected at the lower center of the screen 1. On the upper left of the screen 1 is a stock display 10 indicating the physical strength of the player. Two circles are displayed, and if you take damage from the enemy character 5, they will disappear one by one, all circles will disappear, and if you take one more damage, you will lose. To end the game.

FIG. 2 is a diagram showing a detailed example of a light source that is a light projecting means.
The light source 8 is provided with a plurality of LEDs 8a, and the light from the LEDs 8a is diffused into a predetermined range by the lens 8b and projected. By moving the position of the lens 8b back and forth, the size of the light surface applied to the screen 9 can be adjusted. The size of the light surface is adjusted to be larger than that of the screen 1 so that light unevenness does not occur on the screen surface. The shadow formed on the screen 1 is moved by the player back and forth, so that the vicinity of the boundary is blurred depending on the position of the player, and even when standing at a position where it does not blur, the light source 8 is not a point light source, so Intermediate gradation). In addition, when there is a thin part such as an arm part or a tool, the influence of light wrap around becomes large, and there may be an intermediate gradation as well. In order to determine the shadow formed in this way as a shadow, as described later, it is determined whether or not it is below a certain darkness (for example, 50% of the brightness when the screen is illuminated without being blocked by the light source). It will be judged by calculation.

Here, the basic rule of this embodiment will be described.
When the enemy character appears on the game screen and battles with the shadow player character, the enemy character loses when the player's physical strength is lost by the player character attack, or when the player character receives damage from the enemy character three times. It is a game that becomes.
As shown in FIG. 3A, when the enemy character is facing forward, it is an enemy attack, and the player moves the stage so that the shadow does not overlap the enemy character.
The enemy character 5a comes toward the shadow 4a of the player 3a. When the player's shadow 4a overlaps the enemy character 5a, the player character receives damage. When taking damage, the player goes down 1 and the stock display 10a of the player at the upper left of the screen disappears. Even if the player 3a protrudes from the screen 1, the player's stock display 10a disappears. If the player's stock display 10a disappears and the player receives further damage, the game is over.

As shown in FIG. 3B, when the enemy character is facing back (back), it is an attack of the player, and the player moves the stage so as to overlap the enemy character.
The enemy character 5b tries to escape from the shadow 4b of the player 3b. If the player's shadow 4b overlaps the enemy character 5b, the enemy character 5b is damaged. For example, the amount of damage varies depending on the shadow overlap (percentage of overlapping parts) and the overlapping time. The enemy character 5b is pushed out by the magnitude of the damage, and the eye color changes from blue>yellow> red. If the enemy character 5b has red eyes and further damage is applied, the enemy character 5b is destroyed.

The effect of the action of the player expanding and reducing the shadow is as follows.
Examples when the shadow is enlarged are shown in FIGS. 4A and 4B.
When the player 3c moves away from the screen (closer to the light source), the shadow 4c increases, which is advantageous for attacking the enemy character 5d. However, when the enemy character 5d turns and attacks, the shadow 4d of the player 3d is large, which is disadvantageous for avoidance.
An example of reducing the shadow is shown in FIGS. 5A and 5B.
When the player 3e approaches the screen 1 (away from the light source), the shadow 4e becomes small, which is advantageous in avoiding the attack of the enemy character 5e. However, when the enemy character 5f turns around and escapes, the player 3f cannot immediately increase the shadow 4f, so that the player 3f's attack is difficult to hit.

A player character (character shadow) and an enemy character used in such basic game rules are defined, and an ID, a name, a model file name, an HP condition, an attack state condition, and a damage condition to be given are described. Further, a player attack basic value and a player attack coefficient are described in the player character.
Table 1 shows specific examples of items to be defined by the player character.
The ID is “0x1000”, the name is “player”, and the model file name is none.
As shown in Table 2, A1 of the HP condition shown in Table 1 is “Initial 1 (when hitting an enemy of attack, 1 immediately goes down)”.
A1 of the attack state condition shown in Table 1 is “a hit enemy character is in an avoidance state” as shown in Table 3.
As shown in Table 4, the damage condition given in Table 1 is “calculated by player attack base × player attack coefficient” (set values in Tables 5 and 6), and damage is calculated by this calculation.

The player attack base value shown in Table 5 is the number of consecutive hit frames (when operating at 60 fps). The attack base value is “20” for “1”, “2”, “3”, “4”, and “5”, respectively. “40” “60” “80” “100” is set.
Furthermore, the player attack coefficients shown in Table 6 are “0.2f” and “0.2f” for the maximum overlap areas “1-30”, “31-60”, “61-90”, “91-99”, and “100”, respectively. “0.3f”, “0.4f”, “0.5f”, and “1.0f” are set.

Next, specification examples of enemy characters will be described.
As described with reference to FIGS. 3A and 3B, the enemy character has two states of “attack state” and “evasion state”.
The definition of the enemy character is the same as that of the player character in which the ID, name, model file name, HP condition, attack condition and damage condition to be applied are set.
In Table 7, IDs are described from “0x8000” to “0x8003”, the names are “Kabutomushi”, “Hamster”, “Dog”, “Robo”, and the model files are “Beetle.mdo”, “Hamster.mdo”, “Dog”. .Mdo "," Robot.mdo ", HP conditions are" A2 "," B2 "," D2 "," E2 ", attack conditions are" A2, "" B2, "" C2, "" E2, "damage conditions to be given are" A2, "" A2 "," A2 "and" A2 ".
The enemy character HP conditions “A2”, “B2”, “D2”, and “E2” are “initial value 30”, “initial value 40”, “initial value 50”, “initial value 60”, and “initial value 100” as shown in Table 8. It is.
HP starts from the initial value and decreases as damage is received. When it becomes less than zero, the enemy character goes down and displays an explosion. (In the process of receiving this damage, the eye color changes to the set color of blue>yellow> red as described in FIG. 3B according to the remaining HP. Change).

上記表１〜表１０は、後述するゲームプログラムのデータ値としてＲＯＭに格納され、このデータ値をＣＰＵが読み出して処理するものである。 As shown in Table 9, “A2”, “B2”, “C2”, “D2”, and “E2” of the enemy character attack state conditions are respectively “from 30 degrees to the left and right and 30 degrees to the top and bottom. "When facing the direction within 30 degrees to the left and right from the state facing straight""When facing the direction within 40 degrees to the left and right and from within 30 degrees up and down from the state facing the front" From the state facing the front “When facing in a direction within 45 degrees to the left and right and within 30 degrees in the up and down direction” “when facing in a direction within 50 degrees to the left and right from a state of facing the front”.
The damage condition A2 to be given is always “1” as shown in Table 10.

Tables 1 to 10 are stored in the ROM as data values of a game program to be described later, and these data values are read and processed by the CPU.

FIG. 6 is a circuit diagram showing an embodiment of a circuit of a game apparatus using a projected shadow according to the present invention, and is a case where the above game is executed.
The projector 7, the scanner (CCD camera) 6 and the light source 8 are connected to the video control unit 21, the imaging control unit 22 and the light source control unit 23, respectively.
The image extraction unit 26b receives and takes in the first game screen projected by the projector 7 on the screen 1 from the game control unit 26a, and extracts the position and size of the enemy character on the first game screen. Further, the second game screen of the screen 1 on which the shadow is projected is taken from the CCD camera 6, the difference between the first game screen and the second game screen is taken, and the difference portion is extracted as the position and size of the shadow. .
The hit determination unit 26d determines whether or not the shadow extracted by the image extraction unit 26b and the character on the game screen overlap each other on the screen, and determines that the hit has occurred.
The hit detection means corresponds to a part composed of the image extraction unit 26b and the hit determination unit 26d. Details of image extraction and hit determination will be described later.

When the enemy character on the game screen is facing backwards, that is, when the player makes a hit determination as an attack against the enemy character, the damage processing unit 26e deals damage corresponding to the overlapping area to the enemy character. Image processing of such an enemy character corresponding to damage is performed. In addition, when the enemy character on the game screen is forward-facing, that is, when the hit determination is made as an attack on the enemy character player in the attack system state, damage corresponding to the overlapping area is given to the player, Image processing, that is, image processing for deleting one of the physical strength displays 10 of the player at the upper left of the screen 1 is performed.
The video control unit 21 performs display control of the enemy character for such image processing and display control of the screen in which one of the player's stock physical strength displays 10 is turned off at the corner of the screen.
The damage processing display means is a portion configured by a damage processing unit 26e and the video control unit 21.

The ROM 24 stores a control program for controlling the entire game device, a battle game program, and necessary game data. The RAM 25 is used as a work area where the CPU 26 performs calculations and plays a role of temporarily storing data. The CPU 26 reads the control program from the ROM 24, realizes the function of the game control unit 26a, performs game standby screen display and sound processing, and outputs BGM and the like from a speaker (not shown). In addition, the functions of the image extraction unit 26b, the hit determination unit 26d, and the damage processing unit 26e are realized by reading and executing a battle game program.
The input device 27 is an operation unit such as a button operated when starting the game device, and further a coin insertion device (not shown) for playing a game is installed.

Next, the flow of the entire game machine will be described with reference to the flowchart of FIG. 7 and FIGS. 1 and 6.
In this flowchart, the player inserts a predetermined coin, the game is started (step (hereinafter referred to as “S”) 001), the player 3 stands on the stage 9, and the shadow of the player is projected on the screen 1 by the light source 8. The case where the main routine is entered from the state of being present will be described. When the CPU 26 reads the game program from the ROM 24 and executes it to start the main routine (S002), the game control unit 26a creates a rendered image of only the enemy characters (which is an enemy character hit determination image) (S003). ). The image extraction unit 26b takes in this image and extracts an enemy character used for hit determination (S003).
FIG. 11 shows details of the procedure for extracting the image of the enemy character.
The image extraction unit 26b captures the enemy character image as shown in FIG. 11A, and divides the enemy character screen into blocks of a predetermined size as shown in FIG. 11B. For each block, a block having a pixel ratio equal to or higher than a set value is extracted as an effective block. As a result, an effective block 31 corresponding to the enemy character is extracted as shown in FIG.
FIG. 11D shows that each block unit is valid and invalid and is associated with “1” and “0”, and the image extraction unit 26b extracts such data for the enemy character.

Next, the game control unit 26a creates a rendered image of the entire game screen including the background and the stock display 10 (S004).
The game control unit 26a sends a command to the photographing control unit 22 to scan and capture the image on the screen 1 from the CCD camera 6. The game control unit 26a takes in an image in which the shadow of the player and the game screen are combined from the CCD camera 6 (S005). The image extraction unit 26b subtracts the rendered image of the entire game screen from the image acquired in S005, and extracts the shadow image of the player (S006).
FIG. 9A shows details of the procedure for extracting the image of the player character.
FIG. 9A (a) is an example of an image in which an enemy character is combined with a background screen and a stock display, and FIG. 9A (b) is an example of an image obtained by scanning a screen image on which a shadow of a player is projected. . As described with reference to FIG. 11 for each image, the screens of FIGS. 9A (a) and (b) are divided into blocks of a predetermined size (FIGS. 9A (c) and (d)).

The image extraction unit 26b refers to the luminance information (RGB) of all pixels for the unit blocks of the images in FIGS. 9A (c) and 9A (d), and obtains the average brightness in the block.
FIG. 9B (a) and FIG. 9B (b) display the brightness of each unit block obtained in this way.
The image extraction unit 26b subtracts each block at the same address in FIG. 9B (a) from each block in FIG. 9B (b) to obtain a difference in brightness of the block (FIG. 9B (c)). Then, a block having a difference greater than the set value is extracted as a valid block as a player character. The block indicated by the numeral 35 in FIG. 9B (c) is a block having a value less than the set value, and this portion is not extracted, and the block indicated by the numeral 36 is extracted because it is a block having a value greater than or equal to the set value.
FIG. 9C shows a diagram in which the block units are valid and invalid and are associated with “1” and “0”, and the image extraction unit 26b extracts such data for the player character.

When the image data of the enemy character and the player character is thus extracted by the image extraction unit 26b, the information is sent to the hit determination unit 26d, and control is passed to the hit determination unit 26d.
The hit determination unit 26d determines whether the enemy character and the player character have hit (S007). If no hit is found, the routine is terminated. If a hit is found, hit processing is performed and then the routine is terminated (S008, S009).
12A and 12B are diagrams for explaining the details of the hit determination.
FIG. 12A shows an example in the case of no hit. FIG. 12A (a) shows the player character data binarized for each unit block, and FIG. 12A (b) shows the enemy character data binarized for each unit block. FIG. 12A (c) is data obtained by multiplying the blocks at these same positions. Since the effective block positions of the player character and the enemy character are different, all unit blocks are “0” and do not hit.

FIG. 12B shows an example of a hit. FIG. 12B (a) shows player character data binarized for each unit block, and FIG. 12B (b) shows enemy character data binarized for each unit block. FIG. 12B (c) is data obtained by multiplying the blocks at the same position. Since four valid unit blocks “1” are overlapped, it is determined as a hit.
When the player character is off the screen, there is no valid block in the player character data, so there is no overlap with the effective block of the enemy character. To migrate.

FIG. 8 is a flowchart showing a subroutine of HIT processing.
When the hit is determined, the damage processing unit 26e determines whether or not the player character is off the screen (there is no effective block in the image of the player character) (S101). If the player character is off the screen, the player character is damaged (S103). The damage that the enemy character gives to the player character is always “1” as shown in Table 10. That is, one screen stock display is erased. When the game control unit 26a receives the damage data from the damage processing unit 26e, the game control unit 26a updates the stock display data read to the RAM 25 so that one stock display disappears.
After damaging the player character, it is determined whether or not the game is over (S104). If the player character receives damage after all the stock has run out, the game ends as a game over. Otherwise, one of the stock displays is deleted and the hit process is terminated.

On the other hand, if it is not a ringout, it is determined whether or not the player is under attack. This is determined based on whether the image of the enemy character is forward or backward from the game screen. When the image of the enemy character is positive, the player is attacked and takes damage (S103). When the damage control unit 26e receives the damage data, the game control unit 26a updates the stock display data read to the RAM 25 so that one stock display disappears.
Further, when the image of the enemy character is facing backward, the enemy character is damaged based on the damage condition as shown in Table 4. When the damage processing unit 26e receives the damage data, the game control unit 26a updates the physical strength data so that the physical strength of the enemy character decreases the amount of damage. Further, for example, image processing for adding an image of a shock wave 11 as shown in FIG. 4A to the game screen on which the enemy character is shown is performed, and further, the image processing is performed so that the eye color of the enemy character becomes a color corresponding to the damage. Such image processing data is transmitted to the video control unit 21, and the video is projected from the projector 7.

  When the enemy character receives damage based on the calculation of Table 4, for example, when the number of consecutive hit frames is “3”, the attack base value is “60” from Table 5, and the maximum overlap area of the player is “31-60”. In this case, since the attack coefficient is “0.3f” from Table 6, the player attack base value is obtained as a basic attack value of 60 × 0.3f = 18f, and the enemy character takes damage of “18f”. . The maximum overlapping area is an area where the enemy character overlaps with the shadow of the player. If the entire extracted image of the enemy character is 100%, in the above example, 31% to 60% overlap.

Next, the game control unit 26a determines whether or not the enemy character's physical strength becomes 0 due to the damage in S105 and the explosion process should be performed (S106). When the enemy character's physical strength is 0 or less, the enemy character is blasted and the next enemy character is called (S107). Thus, the hit process ends.
The game process flow in FIG. 7 is repeatedly executed until the game is over.

The above embodiment has shown an example in which the attack coefficient is changed with respect to the area where the enemy character overlaps as the damage given by the player. However, even if a parameter for changing the attack coefficient with respect to the overlapping time is added, Good. For example, the attack coefficient is increased as the overlapping time becomes larger, and if the overlapping time is shorter, the damage cannot be so great.
Further, the damage defined in Table 10 as the definition of the enemy character is always “1”, and the example of losing the player when hit three times has been described. Instead, when the player loses, not only the number of hits but also the time when the physical strength becomes zero can be used.
In this invention, not only the input / output contents are influenced by the player's body shape, but also the part protruding from the player can be made as a shadow by clothes and belongings, so each time a game is held, the belongings are changed or the clothes are changed. You can change the content of the offense and defense.

FIG. 10 shows an example in which a helicopter robot that is controlled by a player with a remote controller is used as a player character.
If the helicopter robot 37 is a player character, the shadow 39 can be guided to the upper surface of the screen 1 away from the stage surface by the remote controller 38, and the entire screen can be used effectively as a game field.
In the example of FIG. 1, a shadow can be projected on the upper part of the screen 1 by the player jumping up, but it is an instant, and the concept of time as an attack coefficient (can be greater damage as the overlapping time is longer) In the case where is inserted, when it jumps up and overlaps with the enemy character, attack damage cannot be practically given.
