[0034]
The present invention also provides:
An information storage medium for storing information for performing a shooting game using an attack defense input unit that selectively inputs an attack state and a defense state, and a shooting device that performs shooting toward a target displayed on a display unit. ,
Information for allowing the player to selectively input the attack state and the defense state using the attack defense input means during the game;
When the attack state is selected, based on the input from the shooting device, information for performing a game calculation to shoot each other with the enemy appearing in the game space;
Information for performing a game calculation for causing a virtual player in the game space to perform a danger avoiding operation when the defense state is selected;
It is characterized by including.
[0035]
In shooting games, not only attacks but also avoiding danger, for example, fending off enemy attacks, is an important element of the game. According to the present invention, the player can select and input the attack state and the defense state by the attack defense input means together with the shooting input by the shooting device. For this reason, it is possible to provide a shooting game device that performs a game with a reality close to an actual battle scene, in which the enemy is attacked while defending against the enemy attack.
[0036]
In particular, according to the present invention, it is possible to enjoy a game rich in change and full of tension that could not be experienced in a game of simply shooting a target.
[0037]
Here, the attack defense input means is:
It is preferably formed as a foot operation type input means operated by a player with his / her foot, and the player selects and inputs an attack state and a defense state by operating the foot operation type input means with his / her foot.
[0038]
By doing so, the player can input the attack state or the defense state with his / her foot, so that the player can make a shooting input by the shooting device using his / her hand as in the conventional case. Moreover, since the input is performed with hands and feet, the input operation of the game is not complicated as compared with the case where any input is performed with only the hand, and even a beginner can perform the input operation easily.
[0039]
The attack defense input means
An inclination sensor provided in the shooting device may be included, and the player may be configured to selectively input an attack state and a defense state by operating the shooting device to a predetermined inclination.
[0040]
For example, using the mercury energization effect as a tilt sensor, using a mercury switch that turns on and off when a predetermined tilt is reached, and providing this to the shooting device, the shooting device is operated to a predetermined tilt Sometimes it may be configured to detect this.
[0041]
Even in this way, the player performs the selection input of the attack state or the defense state by using the shooting device similarly to the shooting input, so that even the beginner can easily perform the input operation without complicating the game input operation. Can be done.
[0042]
The attack defense input means
Player position detecting means for detecting the play position of the player;
Position detection means for determining whether the detection position is an attack state or a defense state;
The player can select the attack state and the defense state by moving to the attack position or the defense position while watching the screen of the game space displayed on the display means.
[0043]
By doing so, the player performs selection input of the attack state or defense state by moving himself to the attack position or defense position, so the player moves the body in the same way as in actual battle, You can enjoy shooting games by operating a gun.
[0044]
At this time, by setting a position imitating the game space displayed on the game screen as the defensive position, for example, a position hidden behind the object, the player can simulate the battle of the game space displayed on the game screen. I can do it.
[0045]
The game calculation means includes
Timer means for measuring the duration of the attack state input by the attack defense input means;
You may form so that the attack capability control means which changes the enemy's attack capability according to the measured duration may be included.
[0046]
The game calculation means includes
When the attack state is selected by the attack defense input means, the attack count measuring means for measuring the enemy attack count;
It may be formed like a shooting game device including attack capability control means for changing the attack capability of the enemy according to the number of attacks measured by the attack count measurement means.
[0047]
With the above-described configuration, the enemy's attack capability is initially low and gradually becomes high, for example, when the player enters the attack state. Once the player enters the defense state, the enemy's attack ability is reset at that point.
[0048]
Such an enemy attack capability may be any factor that determines the strength of the enemy, and includes, for example, the accuracy of the enemy attack on the player, the destructive power of the enemy weapon, and the number of enemies. In this way, by changing the enemy attack capability in accordance with the duration of the attack state, the enemy attack capability can be improved as the duration of the attack state increases.
[0049]
That is, in the attack state, the player can attack the enemy, but is simultaneously exposed to the enemy's attack.
[0050]
For example, it is assumed that the factor that determines the strength of the enemy is the hit accuracy of the bullet fired by the enemy. In this case, if the hit rate is set high, there is a high probability that an enemy bullet hits the player as soon as the player enters the attack state, and the player is often attacked soon after attacking the enemy. Especially when a beginner plays a game, it is difficult for players to grasp the rhythm of enemy attacks. For this reason, as soon as the player wants to attack the enemy, the enemy is killed, and the game may end before he can afford to enjoy the game.
[0051]
Also, if the hit rate is set low, the enemy's bullets do not hit the player very easily, and the game tension is lost. In this case, it is not possible to enjoy the original fun of the game of using attack defense and enjoying shooting.
[0052]
On the other hand, the present invention is unlikely to be played immediately after the player moves to the attack state, so that it is possible to prevent a case where the game ends without a time for a beginner to enjoy the game. Furthermore, by setting a situation in which the enemy becomes stronger as the attack state continues longer, it is determined that the player should switch the attack defense at an appropriate place. As a result, it is possible to realize a shooting game device in which the player can enjoy the game while naturally switching the attack state or the defense state.
[0053]
The game calculation means includes
It is preferable to include a reload control means for reloading the player's attack ability based on the switching between the attack state and the defense state.
[0054]
Reloading means fulfilling the player's attack capability. The attack capability of the player controlled by the reload control means is, for example, the number of bullets that can be fired by the player, the attack capability of the shooting device, and the energy required for the attack.
[0055]
Thus, by reloading the player's attack ability based on the switching of the attack state or the defense state, it is possible to realize a shooting game device in which the player naturally switches the attack state or the defense state.
[0056]
The foot operation type input means includes:
An entry pattern instruction means for the player to input an entry pattern from the defense state to the attack state;
The game calculation means includes
Based on the instructed entry pattern, the player can be configured to calculate an operation when entering the attack state from the defense state.
[0057]
In this way, a plurality of patterns in which the player enters the attack state from the defense state can be set. For example, the entry pattern may be set so that the player jumps out and moves to the attack, or may be set so that the player moves to the attacking posture while gradually moving. Further, the attack position of the player after entering may be set to change according to the entry pattern.
[0058]
With such a configuration, the situation determination of what entry pattern the player chooses depending on the game development is also an important element of the game, and as a result, shooting that can enjoy a variety of attacks A game device can be realized.
[0059]
The entry pattern instruction means includes
It includes a pressure sensor that detects the player's stepping strength, and can be configured to indicate an entry pattern based on the stepping strength.
[0060]
In this way, the player can instruct the entry pattern from the defense state to the attack state, depending on the strength of the foot operation type input means. For example, if the input means is formed so that the player jumps and enters the attack state vigorously by stepping on strongly, the instruction content and the instruction action are naturally combined. For this reason, the player can instruct entry operation without a sense of incongruity.
[0061]
In the shooting game device in which the game screen on the display means is formed as the player's view image, the game computing means shows how the player jumps and enters the attack state from the defense state. It is preferable to perform the game calculation so as to be expressed as an image that can be seen from.
[0062]
In the present invention, the display means may be formed using a head mounted display.
[0063]
When the player selects and inputs the attack state and the defense state by moving to the attack position or the defense position while looking at the screen of the game space displayed on the display means, the normal display means allows the player to play the game on the screen. It is difficult to feel that the player is sharing the space, and the reality is not good enough. Also, since the player must shoot while operating, a considerably large display means is required.
[0064]
However, by using a head-mounted display as the display means, the entire field of view of the player becomes a game space. For this reason, it is possible to provide a shooting game apparatus that allows a player to experience a simulated experience while enjoying the same feeling as if the player is actually located in the space.
[0065]
Next, preferred embodiments of the present invention will be described in detail with reference to the drawings.
[0066]
FIG. 1 shows an external perspective view of a shooting game apparatus to which the present invention is applied. In this shooting game apparatus, a display 12 is provided inside the housing 10 toward the player P. The display 12 is of a raster scanning type, and a CRT is used in this embodiment.
[0067]
In addition, a gun case 14 is provided on the front surface of the housing 10 so that the gun 20 is accommodated. The gun 20 is configured to be connected to a circuit inside the housing 10 via a cable.
[0068]
Also, a coin insertion slot 16 is provided below the housing 10, and when the player inserts a coin and presses the start button 18, a shooting game is started.
[0069]
When the player P holds the gun 20 and goes to the display 12, a game screen is displayed on the display 12. The player can enjoy the shooting game by aiming at targets displayed one after another on the game screen and operating the trigger button.
[0070]
The appearance configuration of the above-described shooting game apparatus is basically the same as that of a conventional general shooting game. The difference is that a foot operation type input unit 30 is provided at a position where the player can operate with the foot at the lower front of the housing 10. The foot operation type input unit 30 functions as attack defense input means for the player to selectively input an attack state and a defense state in accordance with the game development, and will be described in detail later.
[0071]
FIG. 2 shows a circuit configuration of the game device according to the present embodiment.
[0072]
In the shooting game apparatus of the present embodiment, the game PCB 40 calculates a game screen on which targets having an attacking ability appear one after another according to a predetermined game program, and displays the game screen on the display 12.
[0073]
The game PCB 40 synthesizes a game calculation unit 110 that calculates a game screen according to a predetermined game program, an image synthesis unit 120 that displays the calculated game screen on the display 12, and a sound signal corresponding to the game development. And a voice synthesizer 130 that outputs to the speaker 50.
[0074]
The game calculation unit 110 is configured to start a game based on the operation of the start button 18 of the operation unit 11.
[0075]
When the player uses the gun 20 to shoot a target, the game calculation unit 110 detects the landing position. When the position of the landing point and the position of the target coincide with each other, it is determined that a bullet has hit, and a screen in which a bullet hits the target is displayed as an image. Thereby, the player can visually recognize whether or not a bullet hits the target, and can enjoy the game.
[0076]
Next, a configuration in which the game calculation unit 110 detects the landing position on the display 12 when the player operates the trigger 26 of the gun 20 will be described.
[0077]
A light receiving portion is formed on the barrel of the gun 20. That is, the gun 20 has a hollow barrel, a lens 22 at the tip of the barrel, and a light receiving sensor 24 at the back, and is configured to detect light 210 from the barrel direction using the light receiving sensor 24. ing.
[0078]
The light receiving sensor 24 has a landing position detection area 200 having a diameter of about several centimeters around a point where an extended line of the barrel intersects the display 12. When the raster scanning of the display 12 passes through the detection area 200, the light receiving sensor 24 outputs a detection signal corresponding to the amount of received light to the game calculation unit 110.
[0079]
In the present embodiment, when the player aims at the target and operates the trigger 26, the trigger signal is input to the game calculation unit 110. Thereby, the game calculation unit 110 controls the image composition unit 120 to flash the display 12 for position detection at the next inter. The light receiving sensor 24 is configured to output a detection pulse when raster scanning on the display 12 is performed with a light amount of a certain amount or more. Since the game calculation unit 110 receives the detection pulse and performs position calculation, when the display 12 is flashed for position detection, the game calculation unit 110 displays the horizontal and vertical rasters when the detection pulse is input from the light receiving sensor 24. Based on the scanning position, X and Y coordinates representing the landing position on the screen are detected. The game calculation unit 110 is configured to determine whether or not the landing position matches the target hit area and perform a hit game effect or a miss game effect.
[0080]
A game played in the shooting game apparatus of the present embodiment is composed of all three stages, and each stage is composed of four areas. As will be described later, 4 to 5 shooting points are set in each area. A time limit is provided for each area, and the game is over if the area cannot be cleared within the time limit. Also, the player is given a certain number of lives, and is configured to lose one life when attacked by an enemy character that is also a target, and to overrun the game when all lives are lost.
[0081]
By the way, in the shooting game of the present embodiment, the player is configured to attack the enemy character appearing on the display screen while receiving an attack from the enemy character.
[0082]
The feature of this embodiment is that the foot operation type input unit 30 is used to properly use the attack state and the defense state, and to perform a gun battle with the enemy character. The attack state is a state in which the player can damage the enemy character by attacking the enemy character while being exposed to the attack of the enemy character, and the defense state is, for example, the enemy by hiding in the shadow of the player. This is a state where the character is attacked and dangerous. Such a shooting battle is performed at every shooting point, and is configured to advance to the next shooting point when the enemy character there is annihilated.
[0083]
3 to 6 are examples of game screens in an attack state and a defense state at shooting points.
[0084]
In the upper center of the game screen, the remaining game time 380 is displayed. This remaining time 380 decreases in real time as the game progresses, and when it reaches 0, the game is over. In addition, a life 390 is displayed in the lower left of the screen. Six lifes 390 are given at the start of the game. Each time the enemy character is attacked, the life 390 is decreased one by one. It becomes. In the lower right of the screen, the remaining number of bullets 370 and the timer 400 for time attack are displayed. The former indicates the number of bullets that the player can use for the attack, and when it becomes 0, the pedal 32 must be released and reloaded as described later. The latter represents the play time from the start of the stage, recorded for each stage, and can evaluate the skill with the total time when the game is cleared. When performing a time attack for competing for the game clear time, the player can know the time until the current time based on the game time displayed by the time attack timer 400.
[0085]
In the game screen of FIG. 3, the shadow of the two wooden boxes is one of the shooting points 310. When the player moves to the shooting point 310, this position becomes the player battle position 310. Then, the player is set to play a gunfight with the enemy character located at the enemy character battle position 320 in the right direction of the screen in FIG. 3 while hiding behind the wooden box and avoiding the bullets of the enemy character.
[0086]
However, the actual player is separated from the virtual three-dimensional game space where enemy characters displayed on the screen exist. For this reason, in the shooting game device of the present embodiment, a virtual player appears in the game space (not displayed on the game screen). The player inputs the attack state and the defense state from the foot operation type input unit 30, thereby operating the position of the virtual player to the attack or defense state and fighting the enemy character. At this time, the visual field image of the virtual player is displayed as a game screen.
[0087]
When the game is started, a screen overlooking the shooting points as shown in FIG. 3 is first displayed on the game screen as a visual image of the virtual player. The viewpoint of the virtual player moves from the bird's-eye view position overlooking the shooting point as shown in FIG. 3 to the player battle position 310 when the shooting battle is gradually performed, and the view image of the virtual player in the meantime is displayed on the game screen. . During this movement, neither the player nor the enemy character 330 can attack, and the input from the gun 20 and the foot operation type input unit 30 is not accepted.
[0088]
When the movement is finished, the virtual player 300 is positioned in the defense state at the player battle position 310 behind the wooden box 340, and the battle is started.
[0089]
7A to 7C are side views showing the positional relationship of the virtual player 300 in the virtual three-dimensional game space. FIG. 7A shows a defense state, and FIG. 7C shows an attack state.
[0090]
In the defensive state, the virtual player 300 has a positional relationship as shown in FIG. 7A with respect to the wooden box 340, and a game screen that is a view image viewed from the viewpoint position 302 of the virtual player 300 in FIG. 7A is displayed on the display. Is displayed as shown in FIG.
[0091]
In the shooting game apparatus according to the present embodiment, when the player is stepping on the foot operation type input unit 30, the player is in an attacking state, and the player steps on the foot operation type input unit 30 while stepping on or with his foot on. When is unlocked, it becomes a defense state.
[0092]
When the battle is started, the enemy character 330 that can be seen from the gap in the wooden box starts shooting. However, if the player is instructing a defense state (a state where the foot operation type input unit 30 is not depressed), the virtual player 300 is hidden behind a wooden box as shown in FIG. You can protect yourself from 330 attacks. In other words, in the defense state, the player cannot be attacked by the enemy character 330 but cannot attack the enemy character 330. However, since there is a limit to the time that can be given for one play, the player must defeat the enemy character 330 out of the wooden box, aiming at the chance of attack of the enemy character 330. Therefore, when the player steps on the foot operation type input unit 30 with any foot, the virtual player 300 comes out of the shadow and is positioned as shown in FIG. 7C in order to take an attack posture.
[0093]
At this time, the viewpoint position 302 of the virtual player 300 continuously moves from the viewpoint position 302 of the virtual player 300 in FIG. 7A in the defense state to the viewpoint position 302 of the virtual player 300 in FIG. 7C in the attack state. Therefore, on the display, the game screen shown in FIG. 4 in the defense state is displayed so as to change continuously from the game screen shown in FIG. 6 in the attack state.
[0094]
In the attack state, the player can attack the enemy character 330. However, the enemy character 330 can also attack the virtual player 300, and if hit, the virtual player 300 is damaged. Therefore, when the player stops stepping on the foot operation type input unit 30 in order to avoid the attack of the enemy character 330, the defense state is again entered.
[0095]
At this time, the viewpoint position 302 of the virtual player 300 continuously moves from the viewpoint position 302 of the virtual player 300 in FIG. 7C in the attack state to the viewpoint position 302 of the virtual player 300 in FIG. 7A in the defense state. Therefore, on the display, the game screen shown in FIG. 6 in the attack state is displayed so as to change continuously from the game screen shown in FIG. 4 in the defense state.
[0096]
As described above, in the shooting game apparatus according to the present embodiment, the player can enjoy shooting in the shooting battle while properly using the attack state and the defense state according to the battle situation in the game space.
[0097]
In the shooting game apparatus according to the present embodiment, the foot operation type input unit 30 includes a pedal 32 on which a player puts his / her foot to perform a stepping operation, and a pressure sensor 34 which detects a pressure applied to the pedal 32, and the sensor 34 is used to detect a pressure value generated when the player steps on the pedal 32.
[0098]
The pressure value detected by the foot operation type input unit 30 is input to the game calculation unit 110, and the game calculation unit 110 performs game calculations in the attack state and the defense state according to the pressure value.
[0099]
In the shooting game apparatus according to the present embodiment, the attacking state is set when the player depresses the pedal 32, and the defense state is set when no pressure is applied to the pedal 32. Therefore, the game calculation unit 110 switches from the defense state to the attack state when the pressure value exceeds a predetermined value, and performs the attack state game calculation while the pressure value exceeds the predetermined value. Then, when the pressure value falls below a predetermined value, the attack state is switched to the defense state, and while the pressure value falls below the predetermined value, the defense state game calculation is performed.
[0100]
Specifically, the game calculation unit 110 switches the attack state and the defense state in such a manner as to change the position of the virtual player 300 in the virtual three-dimensional game space and the attack capability of the player and enemy characters. This is to perform control.
[0101]
The change of the position of the virtual player 300 and the control of the attack ability of the player and enemy characters are performed as follows, for example.
[0102]
That is, when the pressure value is lower than the predetermined value, the game calculation unit 110 determines that the defense state is in effect, and as shown in FIG. 7A, the virtual player 300 covers the wooden box 340 or the like. Perform the operation. The hit calculation of the bullets fired by the enemy character 330 on the game screen is determined by whether or not the virtual player 300 in the game space is hit. Therefore, when in the defense state, the enemy character's bullets are blocked by the wooden box 340 and do not hit the virtual player 300. Therefore, when in the defense state, the player is not damaged by the attack of the enemy character.
[0103]
Further, when the pressure value exceeds a predetermined value, the game calculation unit 110 calculates an attitude such that the virtual player 300 exits from the wooden box 340 or the like as an attack state as shown in FIG. 7C. . In the attacking state, the enemy character's bullets reach the virtual player 300 without being blocked by the wooden box 340, and therefore hit the virtual player 300 with a predetermined probability. Therefore, when in the attack state, the virtual player 300 is exposed to the attack of the enemy character. Therefore, if the bullet of the enemy character hits, the virtual player 300 receives damage and loses one life. The predetermined probability is set by the attack ability control unit 114 of the game calculation unit 110 as will be described later.
[0104]
Furthermore, in the shooting game device of the present embodiment, a game screen as shown in FIG. 4 which is a view image viewed from the viewpoint 302 of the virtual player 300 in FIG. 7A is displayed in the defense state, and FIG. A game screen as shown in FIG. 6 which is a view field image viewed from the viewpoint 302 of the virtual player 300 is displayed. Such a view image of the virtual player 300 is determined by the position of the viewpoint of the virtual player 300. Therefore, the game calculation unit 110 calculates the coordinates of the position of the viewpoint of the virtual player 300 accompanying the change of the position of the virtual player 300. Then, the image composition unit 120 synthesizes an image to be displayed on the display based on the viewpoint position of the virtual player 300.
[0105]
When the pedal is depressed in the defense state, the game screen continuously displays the state of transition from the defense state to the attack state. That is, the game screen displays a state in which the view state image in the defense state displayed on the game screen in FIG. 4 continuously changes to the view state image in the attack state displayed on the game screen in FIG.
[0106]
When the pedal is released in the attack state, the game screen continuously displays the state of transition from the attack state to the defense state. In other words, the game screen displays a state in which the attack state view image displayed on the game screen of FIG. 6 continuously changes to the defense state view image displayed on the game screen of FIG.
[0107]
In the shooting game apparatus according to the present embodiment, when the player steps on the pedal 32, if the pressure value exceeds a predetermined value (except for a state where the pressure value is significantly higher as described later), the virtual player 300 Although the posture changes from FIG. 7A to FIG. 7B and FIG. 7C, when the player releases the pedal 32 before entering the state of FIG. 7C, the posture is changed to return to the position of FIG. Yes. In such a case, the game screen continuously shifts from the screen of FIG. 4 which is the view image of the virtual player in the hidden state to the screen of FIG. 5 which is the view image of the player with a little head up. Then, the screen continuously returns to the screen of FIG. This reflects the action taken when it is judged that it is dangerous when it comes out of the shadow and hides again.
[0108]
When the player releases the pedal 32, the posture of the virtual player changes from FIG. 7C to FIG. 7B and FIG. 7A when the pressure value falls below a predetermined value. However, before the player enters the state shown in FIG. When the pedal 32 is stepped on again, it is formed so as to return from the middle position of FIG. 7B to the position of FIG. 7C again. In such a case, the game screen changes from the screen of FIG. 6 which is the view image of the virtual player in a non-hidden state to the screen of FIG. 5 which is the view image of the player with a slight head-down, and again in FIG. Return to the screen. This is a reflection of the actions taken when it is determined that it is okay when the head is lowered slightly to hide in the shadows and the attack is started again.
[0109]
In addition, the shooting game apparatus according to the present embodiment is formed so that the enemy character 330 cannot damage the player by an attack and the player cannot attack the enemy character 330 in the defense state. That is, in the defense state, the attacking ability of the enemy character 330 and the player is controlled so that all the attacks of the enemy character 330 are regarded as missed, and the input by the player's gun is not accepted.
[0110]
By the way, in the shooting game device of the present embodiment, the enemy characters 330 appearing in the game can set different hit rates one by one, and the bullets shot by the enemy character 330 aiming at the player by the hit rate are released and rubbed. , It is classified as any one of the hits (the probability of occurrence of a miss, blur, and hit is set to be 100% in total).
[0111]
FIGS. 8A to 8C show game screens when the bullets shot by the enemy character 330 are released, rubbed, and hit, respectively.
[0112]
FIG. 8A shows a case of detachment. The missed bullet 352 replaces the bullet effect 354 upon hitting a nearby obstacle. In addition, the place to jump is determined at random from preset coordinates, and this state is not damaged.
[0113]
FIG. 8B shows the case of scraping. The shot bullet hits the edge of the screen and changes to the shot effect 356 where it hits. At the same time, the screen shakes lightly and flashes red for a moment, but this state is not damaged.
[0114]
FIG. 8C shows the case of hit. The hit bullet hits near the center of the screen and replaces the hit effect 358. When hit, the screen will turn red, and at the same time it will shake a lot for 100 inters. In addition, the bullets hit at this time are replaced with special effects for each weapon (gun marks for guns, explosions for bazooka, scars that have been torn for nails, etc.). It should be noted that while the screen is shaken, the player must be sure to remove the bullet even if he / she shoots a bullet against the enemy character 330 (or the bullet may not be shot). Is formed. In this state, the life is set to one.
[0115]
Thus, in the attack state, the player is exposed to the attack of the enemy character 330, and the bullets of the enemy character 330 hit the virtual player 300 with a predetermined probability as described above.
[0116]
When this hit rate is set high, the bullet of the enemy character 330 hits as soon as the player enters the attack state, and the player is often attacked soon after attacking the enemy character. Especially for beginners, the attacking rhythm of the enemy character 330 cannot be grasped, and as soon as it comes out, the game may end without having time to enjoy the game.
[0117]
However, if the hit rate is low, the bullets of the enemy character 330 will not hit the player easily, so the tension of the game will be lost, and the original fun of using the defense defense and enjoying shooting will be lost. End up.
[0118]
Therefore, in the shooting game apparatus of the present embodiment, the attacking ability of the enemy character 330 is initially low after the player enters the attack state, and the attacking ability of the enemy character 330 gradually increases after a while. . Furthermore, once the state is changed to the defense state and then changed to the attack state again, the attacking ability of the enemy character 330 is once reset, and thereafter the attacking ability is gradually increased.
[0119]
In this way, in order to control the attacking ability of the enemy character 330 based on the duration of the attack state, the game calculation unit 110 of the present embodiment includes the timer unit 116 that measures the duration of the attack state, As the duration measured by the timer unit 116 becomes longer, the attack capability control unit 114 that improves the attack capability of the enemy character is formed.
[0120]
When the depression pressure value of the player's pedal 32 exceeds a predetermined value and the timer unit 116 switches from the defense state to the attack state, the timer unit 116 performs a counting operation. When the attack state is switched to the defense state, the count value is reset. If it does in this way, the timer part 116 will count the continuation time after the said state is started in an attack state.
[0121]
Further, as described above, in this embodiment, the attacking ability of the enemy character 330 is determined by the accuracy rate. Therefore, the attack capability control unit 114 controls the attack capability of the enemy character 330 by controlling the accuracy. That is, in the attack state, the attacking ability control unit 114 refers to the count value periodically counted by the timer unit 116, and the higher the count value, the higher the probability of hitting the enemy character 330. Change to be. In the defensive state, the accuracy rate of the enemy character 330 is set so that the probability of hit becomes 0, so that the player is not damaged by the attack of the enemy character 330.
[0122]
In this way, since the possibility that the player will be attacked immediately after moving to the attack state is reduced, it is possible to prevent the case where the game ends without the novice or the like having time to enjoy the game. In addition, by setting a situation in which the enemy character 330 becomes stronger as the attack state continues longer, it is determined that the player should switch the attack defense at an appropriate place, and the attack state or the defense state is switched naturally. It becomes.
[0123]
In the shooting game device of the present embodiment, the strength of the enemy character is controlled according to the duration of the attack state, but the number of attacks of the enemy character after the attack state is started is counted. The strength of the enemy character may be controlled according to the counted number of enemy attacks.
[0124]
Further, in the shooting game apparatus of the present embodiment, the game setting is such that the player uses six guns, and the number of bullets that can be fired at one time is six. For this reason, if the player fires six shots, the bullets run out and the enemy character cannot be attacked. In this state, the attack can be started again only after reloading by shifting to the defense state.
[0125]
FIG. 9 shows a screen displayed when the player tries to shoot the seventh shot even though the bullet has run out. In this case, since the number of remaining bullets is zero, the remaining bullet number display 370 at the lower right of the screen is zero. Then, a RELORD message 420 rises from the lower part of the screen and is displayed with translucent characters in the center of the screen. The RELOAD message 420 disappears when the pedal is released and reloading is performed, and the display becomes a screen in a defense state as shown in FIG. Since reloading was performed at this time, the remaining number of bullets 370 at the lower right of the screen is 6.
[0126]
In the shooting game apparatus of the present embodiment, a remaining number storage area is provided in an area (not shown) of the game calculation unit 110 in order to manage the remaining number of bullets of the player. The game calculation unit 110 instructs the image composition unit 120 to display the remaining bullet number 370 and the RELOAD message 420 based on the remaining bullet number stored in the remaining bullet number storage area.
[0127]
In order to reload the remaining number of bullets 370 of the player based on the switching of attack defense, the game calculation unit 110 is provided with a reload control unit 112. In the reload control unit 112, when the player stops depressing the pedal 31 and the pressure value falls below a predetermined value, the remaining number of bullets set in the remaining number of bullets area is reset to 6. It is configured as follows.
[0128]
In this way, by setting the remaining number of bullets of the player to be reloaded by switching from the attack state to the defense state, the player can play a shooting game while naturally switching between the attack state and the defense state.
[0129]
Further, in the shooting game device of the present embodiment, the foot operation type input unit 30 is formed so as to function also as an entry pattern instruction means for the player to instruct and input an entry pattern from the defense state to the attack state. .
[0130]
That is, the game device according to the embodiment is configured such that when the player steps on the pedal 32, the virtual player 300 performs the entry operation from the defense state to the attack state. In the game device of the present embodiment, the state is produced through the view field image of the virtual player 300 displayed on the game screen.
[0131]
Normally, the operation in which the player depresses the pedal and shifts from the defense state to the attack state is displayed as a game screen of about 60 inters from FIG. 4 to FIG. 5 and FIG. However, when the player depresses the pedal 32 vigorously, the transition operation time is about half, and the screen during the transition from the defense state to the attack state is shown to show the player jumping vigorously. Is displayed as a field-of-view image viewed from a higher viewpoint than FIG.
[0132]
When the player depresses the pedal, a pressure value higher than normal is detected. Therefore, the game calculation unit 110 determines whether or not the player has depressed the pedal 32 with a pressure provided in the foot operation type input unit 30. Judgment is made based on the detection value of the sensor.
[0133]
That is, when the detected pressure value exceeds the predetermined value, the game calculation unit 110 shifts to the attack state. If the detected pressure value greatly exceeds the predetermined value at this time, as described above, the game operation unit 110 vigorously defends. It is formed so as to perform an operation for performing the entry operation to the attack state.
[0134]
Further, the player is not limited to the attack of the enemy character 330 in the defense state. In the shooting game apparatus according to the present embodiment, for example, an object that causes damage to the player appears in addition to the attack of the enemy character 330, such as a rushing car or a hook hanging from the ceiling.
[0135]
FIG. 1 Shows a game screen on which a hook 410 hanging from the ceiling is displayed. The hook 410 swings toward the virtual player. At this time, if the player switches to the defense state and avoids it, the hook 410 collides with the virtual player, and the player is damaged. Therefore, the player must select a defense state even when such a danger is avoided.
[0136]
Further, the manner in which the player takes the defense state is not limited to the case where the player is hidden behind the object. For example, the shooting game apparatus according to the present embodiment is shown in FIG. 0 Shooting points as shown on the game screen are also available. At such a shooting point, there is no shadow that the virtual player 300 should hide, but when the player instructs the defense state, the game effect is such that the virtual player 300 is lying down on the ground and fending off the attack of the enemy character 330. Done.
[0137]
FIG. 12 is a flowchart showing a procedure of game calculation for shooting the attack state and defense state of the game calculation unit 110 of the present embodiment.
[0138]
When the game is started, the defense state is initially started, so the defense state is stored in a state storage unit provided in a storage area (not shown) of the game calculation unit 110 (step 10). The state storage unit is an area for storing the previous input in order to detect an input change between the attack state and the defense state.
[0139]
Then, the following calculation is repeated until the game is over (step 10).
[0140]
In the shooting game apparatus of the present embodiment, a game image is supplied to the game screen every 1/60 seconds. For this reason, the game calculation unit 110 refers to the pressure value input from the foot operation type input unit 30 in this cycle in principle (step 30). Then, it is checked whether or not the state has changed compared to the previous state stored in the state storage unit (step 40).
[0141]
When there is no state change, if the state stored in the state storage unit is an attack state (step 50), the attack state calculation (step 60) is performed. Calculation (step 70) is performed.
[0142]
When there is a change, an entry calculation from the defense state to the attack state or a shift calculation from the attack state to the defense state is performed.
[0143]
When the pressure value input from the foot operation type input unit 30 is significantly higher than the predetermined value (step 80), the virtual player 300 is calculated to jump and participate in the attack (step 90). When the pressure value exceeds a predetermined value (step 100), since the attack state is instructed, a state in which the virtual player 300 participates in a normal attack is calculated (step 110). Since the state has changed, in any case, the attack state is stored in the state storage unit (step 120), and the timer is reset (step 130).
[0144]
When the pressure value does not exceed the predetermined value (step 100), since the defense state is instructed, the state in which the virtual player 300 shifts to the defense state is calculated (step 140). Since the state has changed, the defense state is stored in the state storage unit (step 150), and reloading is performed (step 160).
[0145]
The present invention is not limited to the one described in the above embodiment, and various modifications can be made.
[0146]
In the above embodiment, the attack defense input means is formed as the foot operation type input unit 30, but is not limited thereto.
[0147]
For example, as the attack defense input means, an inclination sensor that uses a current-carrying effect of mercury may be used for the shooting device, and a device that is energized when the shooting device is operated to a predetermined inclination may be used. In this way, the attack state and the defense state can be input depending on the energization, so that even a beginner can easily perform the input operation without complicating the game input operation.
[0148]
Further, as a player position detecting means for detecting the player's play position, at least three members disposed on the player's body in a non-linear manner are mounted by attaching a member including at least one position detecting infrared light emitting unit to the player's body. An infrared light receiving sensor may be arranged. Thus, the position of the player can be detected based on the detection timing shift of the infrared light receiving sensor. Then, the position determination means determines whether the detected position is in an attack state or a defense state. In this way, the player can selectively input the attack state and the defense state by moving to the attack position or the defense position while looking at the screen of the game space displayed on the display.
[0149]
In addition to this, it is also possible to detect the player's posture by installing a reflective infrared sensor toward the head of the player in a standing posture. In this way, the player can selectively input the attack state and the defense state based on the standing posture and the squatting posture.
[0150]
In this way, the player can select and input the attack state and the defense state by moving to the attack position and the defense position, so that the player can play the shooting game with the same feeling as the actual battle operation. I can do it.
[0151]
In addition, by setting a position hidden behind the object, a position where an enemy character's attack can be avoided, etc. as the defensive position according to the game content, the player can simulate the battle in the game space displayed on the game screen. I can do it.
[0152]
In such a case, the display is preferably formed using a head mounted display. In this way, all the player's field of view becomes a game space. Can be provided.
[0153]
Further, the present invention can be applied not only to a shooting game using a gun, but also to a shooting game apparatus using another shooting device.

Enjoy the game. In this game apparatus, the gun is provided with a tilt sensor 1030 that utilizes the energization effect of mercury, and is configured to function as attack defense input means. The main device 1000 includes a CPU 1100, a three-dimensional calculation unit 1210, an image synthesis unit 1220 including an image forming unit 1228, a voice synthesis unit 1300, a working RAM 1302, and a backup memory (memory card or the like) 1304 for backing up data. .
[0155]
In such a home game device, the CPU 1100 executes a program stored in the storage medium 1306 using the RAM 1302, so that it functions as a game calculation means, a timer means, an attack ability control means, and a reload control means. Is formed.
[0156]
Here, in the storage medium 1306, information for allowing a player to select and input an attack state and a defense state using an attack defense input means during a game, and when the attack state is selected, from the shooting device Information for performing a game calculation to shoot each other with an enemy appearing in the game space, and a game calculation for causing the virtual player in the game space to perform a danger avoiding operation when the defense state is selected. It is preferred to store information to do.
[0157]
The present invention can also be applied to a so-called multimedia terminal or a large attraction type game apparatus in which a large number of players participate.
