Abstract

PROBLEM TO BE SOLVED: To control occurrence of a penalty by collision judgement by assisting collision avoidance when a player operates, for example, a movable body object such as a fighter plane which approaches an immovable estate object such as the ground so that even a beginner fully enjoys a game. SOLUTION: In a beginner mode, if the height h of a fighter plane P (a movable body object) reaches a predetermined value, a falling speed is corrected (controlled) by adding a correction vector Vc to an up and down directions speed vector Vv of the fighter plane P based on the relative height difference from the ground L of a proceeding direction place. By buying time up to collision with the ground L, assistance is given so that even a beginner player unaccustomed to operation can avoidance-operate. Moreover, it is possible that the speed reduction by correcting a speed appears to spontaneously occur, as if by avoidance operation, by correcting the position of the plane to a higher position according to the correction vector Vc.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to game information and the like for causing a device to generate an image of a virtual space viewed from a given viewpoint and execute a given game by calculation / control by a processor. .

[0002]

BACKGROUND OF THE INVENTION Conventionally, a plurality of objects are arranged in an object space (virtual space) which is a three-dimensional space,
There is known a game that generates an image viewed from a given viewpoint in an object space. Fighter games classified as flight simulation are one of them. The fighter game is a simulation game in which a fighter object is placed in an object space and players, or a player and a computer, operate the fighter under various situations and play an aerial battle.

One of the situations of a fighter game is a ground attack mission for attacking a ground target such as a tank or a building. FIG. 1 is a diagram for explaining the outline of the action of a fighter in a ground attack mission. In the ground attack mission, the player first searches for the target T, and if found, inputs the operation of lowering the body of the fighter P toward the target T. When the fighter P approaches the target T and the distance D between the fighter P and the target T becomes equal to or less than a predetermined value according to the setting of the attack weapon mounted on the fighter P, the fighter P can attack.
The player sets a target on the target T and presses a predetermined button on the game controller to launch an attack weapon (ground missile M) to attack.

When the anti-ground missile M or the like is launched, the player raises the nose of the fighter P to, for example, the path C1.
You have to input the operation to raise like the course shown in. This is because the aircraft will continue to descend toward the ground and will crash into the ground. When the player raises the altitude of the fighter P to leave the spot, searches for and attacks the next target, and destroys all the targets T, the situation (mission) ends.

[0005]

However, if the player is a beginner, he / she cannot complete the withdrawal action after the attack, and therefore, as shown in FIG.
In many cases, the vehicle collides with the ground as shown by the route C2. The speed of the fighter P is extremely fast as it is, and it takes time to get used to it. If you are flying in a wide air space and are engaged in aerial battle, speed sense does not matter even if you are a beginner, but in the ground attack mission, you will find that you are not accustomed to speed sense because there is a stationary object called the ground. The situation is such that the ground is just around the corner. For this reason, beginners
In many cases, you cannot clear the mission until you get used to the sense of speed and operation. In particular, in the mission clear type game configuration, the game scenario cannot be further advanced, and there is a problem that the player does not play as a difficult game before getting used to it.

The present invention has been made in view of the above problems. The purpose of the present invention is to assist collision avoidance when a moving object operated by a player approaches a real estate object, and determine the collision. It is to suppress the occurrence of penalty due to, so that even beginners can fully enjoy the game.

[0007]

In order to solve the above-mentioned problems, the invention according to claim 1 is a processor
By the control, a setting unit (for example, the game calculation unit 22 in FIG. 5) that sets a virtual space in which a real estate object (for example, the ground L in FIG. 4) is arranged on the device, and a movement that moves in the virtual space. Control means for controlling a body object (for example, fighter P in FIG. 4) according to an operation input (for example, game calculation unit 22 in FIG. 5), and determination for performing collision determination between the mobile object and the real estate object For operating the means (for example, the game calculation section 22 in FIG. 5) and the means (for example, the game calculation section 22 in FIG. 5) that imposes a given penalty when the determination means determines that the collision occurs. Game information, wherein the control means
The posture of the mobile object according to the operation input,
Information for automatically correcting at least one of the control amounts of the moving direction and the moving speed based on the position information of the moving object in the virtual space (for example, the collision avoidance assistance program of FIG. 5). 422) is included.

The invention according to claim 11 is a setting means for setting a virtual space in which real estate objects are arranged,
Control means for controlling a moving body object moving in the virtual space according to an operation input, judging means for judging a collision between the moving body object and the real estate object, and a case where the judging means judges a collision. And a means for imposing a given penalty to the control means, wherein the control means is at least one of a control amount of a posture, a moving direction, and a moving speed of the mobile object according to the operation input. Is automatically corrected based on the position information of the moving object in the virtual space.

Here, the real estate object is, for example, a ground, a water surface, a structure such as a bridge or a building, an underground tunnel, an underground space, etc., which are arranged substantially fixed relative to the world coordinates in the game screen. It is an object. This includes decks in situations where fighter aircraft land on an aircraft carrier. What is a mobile object?
For example, it is a fighter, a helicopter, a hang rider, a flying object such as a space plane, a racing car, a jet ski, a submarine, a given moving character, etc., and is appropriately set according to the content of the game.

Taking a flight simulation game as an example, a game stage and a target real estate object are usually arranged in a virtual space. For example, a moving object (eg, a fighter) operated by a player is a real estate object ( For example, when it is determined that the mobile object has collided with the ground) or when it passes over a predetermined real estate object (for example, a volcano or an exhaust tower), the player has a function that the mobile object has, for example, that the moving speed decreases. There are various penalties for progressing the game, such as being restricted, losing one's own machine, being able to subtract points, and being game over. If the player is a beginner, he / she is not accustomed to the speed sense and operation of the moving object, and thus often receives the penalty as described above, and it is difficult to progress the game as he or she gets used to.

According to the first and eleventh aspects of the present invention, in order to generate the game screen, the posture, the moving direction, and the moving speed of the moving object are calculated and controlled based on the operation input from the player. A correction is applied according to the position of the mobile object, and the mobile object is controlled to maintain a predetermined distance from the real estate object to the extent that collision determination does not occur.

Specifically, for example, when the fighter descends toward the ground, the descending velocity vector of the moving object, that is, the vertical component of the velocity vector, is reduced based on a given relationship to descend. Gradually eliminate the velocity vector. Eventually, the descent velocity vector will disappear, and the aircraft will level out before the collision to avoid collision with the ground, ie, the occurrence of a penalty. Also, if the fighter's attitude is left uncorrected at this time, it will fly horizontally with the attitude facing downward, and if it feels unnatural, adjust the attitude according to the correction to the velocity vector. Will be dealt with by correcting so that it becomes horizontal. As a result, even a beginner can play the game comfortably by reducing the number of times the penalty is received.

Further, the correction for avoidance is executed when the player inputs an operation in consideration of avoidance, and has a function of assisting collision avoidance instead of automatic collision avoidance.
Therefore, on the game screen, the operation and the avoidance motion are more clearly associated and expressed, and the player can be proficient in the operation together with the original purpose of avoiding the penalty.

With respect to avoiding the penalty, as in the invention described in claim 7, the setting means for setting the virtual space in which the real estate object is placed in the device by the calculation / control by the processor, and the inside of the virtual space are set. Control means for controlling a moving mobile object according to an operation input, determination means for determining a collision between the mobile object and the real estate object, and a given penalty when the determination means determines a collision Means for imposing, and the setting means changes the placement position of the real estate object in the virtual space based on the position information of the moving object in the virtual space. Information (for example, the collision avoidance assistance program 422 in FIG. 5) may be included.

In the first and the eleventh aspects, the posture and speed on the side of the moving object are corrected to avoid the penalty. However, in the seventh aspect, conversely, the placement position of the real estate object in the virtual space is determined. Change (correct). For example, when the previous fighter descends to the ground, the altitude of the object coordinate origin position of the ground with respect to the world coordinate is lowered, and a predetermined distance is set between the moving object and the real estate object so that a collision determination does not occur. It is realized by maintaining.

Alternatively, as in the invention described in claim 8, setting means for setting a virtual space in which a real estate object is placed in a device by calculation / control by a processor, and a moving body moving in the virtual space. Control means for controlling an object in accordance with an operation input; determination means for determining a collision between the moving object and the real estate object; and means for imposing a given penalty when the determination means determines a collision. Means for switching the valid / invalid of the collision determination by the determination means based on the position information of the moving object in the virtual space (for example, collision avoidance assistance in FIG. 5). Section 222) for causing the device to function (for example, collision avoidance assistance program 4 in FIG. 5).
22) may be included.

The occurrence of the penalty is brought about by the result of collision judgment between the moving object and the real estate object. According to the invention described in claim 8, the occurrence of the penalty is avoided by temporarily invalidating the collision determination itself. For example, when the previous fighter descends toward the ground, if the fighter reaches a certain altitude or lower, the collision determination provided on the fighter is invalidated, and the aircraft turns to ascend and reaches a predetermined altitude or higher. In that case, it is realized by enabling the collision determination.

Therefore, according to the present invention as set forth in claims 1, 7, 8 and 11, even if the player is a beginner, the fun of the game itself (for example, a fighter game) can be performed without paying attention to the penalty. For example, you can enjoy the tension and exhilaration of the air battle and ground attack. It should be noted that it is possible to correct the mobile object and the real estate object so as not to make a collision determination so as not to receive a penalty, but from the viewpoint of the game, an appropriate penalty is required. Conceivable. Therefore, the level of correction is limited to the level of assistance for avoiding penalties, and for example, if the player does not operate anything, the fighter will continue to descend, albeit gradually, so that it will collide with the ground and receive a penalty. It is preferable to keep it.

Regarding the control of the moving object, as in the invention described in claim 2, in claim 1, the control means, based on relative position information of the moving object and the real estate object, Information for performing the correction (for example, the collision avoidance assistance program 422 in FIG. 5) may be included.

According to the second aspect of the present invention, the same effect as that of the first aspect is obtained, and the moving object is
The control means corrects the moving object according to the degree of approach to the real estate object. For example, in a fighter game, it is not necessary to correct the posture and speed of the fighter when flying at an altitude where there is no fear of collision with the ground. By performing the correction only when, for example, the relative height difference or the relative distance between the moving object and the real estate object becomes a predetermined value or less, it is possible to reduce the calculation load and improve the calculation speed.

In addition, as in claim 3, claim 1 or 2
In the above, the control means may include information (for example, the collision avoidance assistance program 422 of FIG. 5) for changing the correction amount according to the displacement of the position information.

According to the third aspect of the present invention, the same effect as that of the first or second aspect can be obtained, and the correction amount to the moving object according to the displacement of the relative position information of the moving object and the real estate object. By properly setting, it is possible to prevent the fact that the correction is being applied from appearing unnatural. Specifically, for example, when a fighter is descending toward the ground, if the correction is suddenly made from a predetermined altitude to the moving speed, especially the descending speed component,
It gives an unnatural impression of a sudden deceleration even though nothing is done. Therefore, the relative altitude difference is calculated as the position information, and the correction is decreased when the relative altitude difference is large, and the correction is increased as the relative altitude decreases. As a result, the correction is gradually performed, and when it is near the ground, it is largely corrected, and the correction can appear natural.

Alternatively, as in the invention described in claim 4, in any one of claims 1 to 3, the control means further comprises:
Information for performing the correction based on the moving speed of the moving object (for example, the collision avoidance assistance program 422 in FIG. 5) may be included.

In claims 1 to 3, the correction is made only on the basis of the position information of the moving object, but under the condition that the moving object moves at a high speed, the speed of the moving object is also taken into consideration, so that Can be effectively corrected. For example, when a fighter is descending toward the ground and performing a collision avoidance operation, the radius drawn by the avoidance path of the fighter differs depending on the turning ability setting and the moving speed of the fighter.
Normally, the radius drawn by the avoidance path increases in proportion to the speed, so depending on the speed, the turning ability of the fighter cannot avoid the collision. Therefore, for example, when the speed of the mobile object exceeds a predetermined determination value at a predetermined altitude, the posture and speed of the mobile object are corrected so that the collision can be avoided within the turning ability of the fighter. Therefore, according to the invention described in claim 4, the same effect as in any one of claims 1 to 3 is obtained, and the correction is performed not only based on the position information of the moving object, but the speed of the moving object is changed. By also considering the relationship of (1) and performing the correction, it is possible to assist the avoidance of the collision without calculating the position information.

Further, as in the invention described in claim 5, in any one of claims 1 to 4, the control means performs the correction in a direction to avoid a collision between the moving object and the real estate object. Information (eg, FIG. 5)
The collision avoidance assistance program 422) may be included.

According to the invention described in claim 5,
In addition to achieving the same effect as in any one of 4 above, by performing the correction to the moving object in the direction of avoiding the collision with the real estate object, the original purpose of avoiding the collision with the real estate object is achieved, and at the same time, for beginners. It can provide a trigger for avoiding a collision and encourage familiarity with the operation. For example, in a fighter game, it is possible to make time for the player to perform a collision avoidance operation by correcting the descent speed of the fighter and extending the time of collision. At the same time, the posture of the fighter is corrected and the nose is raised (the process of turning to the direction to avoid the collision), so that the player is as if the descending speed was reduced by steering to avoid the collision. In addition to showing naturally, it is possible to visually convey the necessity of the avoidance action, specifically, the action of raising the nose.

Further, in order to avoid the penalty more effectively, in the invention according to claim 7, in any one of claims 1 to 6, the moving destination of the moving object after a lapse of a given time is set. Information for causing the device to function in advance as a calculation unit (for example, the collision disclosure auxiliary program 422 in FIG. 5), and the result of the calculation by the calculation unit,
Information for causing the device to function as a prediction determination unit that determines whether or not the moving object collides with the real estate object (for example, the collision avoidance assistance program 422 in FIG. 5), and the control unit causes the prediction to be performed. Information for performing the correction when the determination means predicts that a collision will occur (for example, the collision avoidance assistance program 42 in FIG. 5).
2) and may be included.

Here, the moving destination of the moving object after a given time elapses is an arrival position predicted when the current moving speed is maintained, for example, a frame in which the game screen is updated. The unit is position coordinates after n frames (n is an integer). According to the invention described in claim 7, the same effect as in any one of claims 1 to 6 is obtained, and it is determined in advance whether there is a possibility of collision with the real estate object at the predicted arrival position of the moving object. By doing so, it is possible to perform more advanced correction and to cope with complicated terrain. Specifically, for example, when a fighter flies in a valley, the moving speed of the fighter is referred to, and a predicted arrival position (that is, a position (n) after n frames (n Is a whole number)), and it is judged that there is a possibility of collision when there is a cliff in the valley on the topographical data, and the collision avoidance is corrected. By appropriately selecting the number of frames to be predicted, it is possible to set the distance at which the collision avoidance correction is started. In this way, by always predicting a collision in the traveling direction, it is possible to appropriately avoid the penalty even for a real estate object having a complicated shape.

According to a ninth aspect of the present invention, setting means for setting a virtual space including terrain, and a moving object flying in the virtual space are operated by the processor according to an operation input. Game information for causing a control means for controlling the mobile object and a determination means for determining a collision between the mobile object and the terrain to be functional, wherein the control means controls the mobile object according to the operation input. At least one of the control amounts of the posture, the moving direction, and the moving speed of the moving object is automatically corrected based on the position information of the moving object in the virtual space, and the altitude of the moving object is low. It is characterized in that it includes information (for example, the collision avoidance assistance program 422 in FIG. 5) for increasing the correction amount as it goes.

On the game screen, the terrain forming the game stage, such as the ground and targets, is displayed, and the player inputs a moving object flying above the terrain, such as a fighter, from the game controller or the like. And manipulate. Here, for example, when a fighter descends toward the ground to bomb a target and reaches a certain altitude,
It is judged necessary to avoid collision with the ground. Then, when calculating and controlling the movement of the fighter according to the operation input of the player, the vertical component of the speed of the fighter, that is, the descending speed is corrected (subtracted) based on the given relationship, and the time until the collision is reached. To make time for the player to perform collision avoidance operations. Also,
Along with the speed correction, the attitude of the aircraft is corrected to be horizontal. By setting the given relationship such that the correction amount increases as the altitude decreases, the correction amount can be made to appear as if the decrease in the descending speed due to the correction is due to steering. According to the invention described in claim 9, it is possible to reduce the number of times a moving object collides with a real estate object and receive a penalty, and the player can enjoy the original game without worrying about the penalty, for example, a fighter game. Then you can enjoy the tension and exhilaration of the air battle and ground attack.

The tenth aspect of the present invention is an information storage medium for storing the game information according to any one of the first to ninth aspects.

According to the invention of claim 10, claim 1
It is possible to provide an information storage medium having the same effect as that of any of

BEST MODE FOR CARRYING OUT THE INVENTION [First Embodiment] A first embodiment of the present invention will be described below with reference to FIGS.
In the first embodiment, the present invention is applied to a fighter game using a home-use game machine, and avoids collision with the ground during a ground attack mission in a state where the beginner mode is selected. Although described, the application of the present invention is not limited to this. For example,
The object of collision avoidance is the ground, but it may be the water surface, or the ceiling part of the cave structure may be replaced in place of the ground.

[Description of Configuration] First, the configuration of the present embodiment will be described. FIG. 2 shows a game device 1 for home use according to the present invention.
It is a figure which shows an example at the time of applying to 200. In the figure, the player looks at the game screen displayed on the display 1202 and looks at the game controller 120.
4, Enjoy the control of the fighter P etc. by operating the cross key, analog stick, various buttons, etc. provided in 1206. In this case, the game information such as the game program and the initial setting data necessary for executing the game is a CD-ROM which is an information storage medium detachable from the main body device 1210.
1212, IC memory 1214, memory card 1216
Etc.

[Explanation of Principle] Next, an outline of the principle of the present embodiment will be described. FIG. 3 is a diagram illustrating an example of handling the position, speed, and attitude of the fighter P in the virtual space. As shown in the figure, the position of the fighter P in the absolute coordinates of the virtual space, that is, in the world coordinates is determined by the object coordinate origin PG, and the traveling direction is expressed together with the position of the body tip PT. As for the attitude of the aircraft, the traveling direction is defined as the Z axis (roll axis) of the object coordinates, the horizontal direction of the traveling direction is the Y axis of the object coordinates (yaw axis), and the vertical direction of the traveling direction is the X axis (pitch axis) of the object coordinates. , Is described as the rotation angle of each axis. In addition, the velocity and acceleration are determined, the movement of the fighter P is calculated, and the position for each frame can be obtained.

The position, posture, speed, acceleration and the like of other objects (for example, the anti-ground missile M, the target T, the ground L, etc.) are similarly set. In this embodiment, the world coordinates are the Z-axis in the screen depth direction and the Y-axis in the screen vertical direction.
The left-handed coordinate system is used as the axis, and the Y-axis coordinate value 0 is described as 0 m above sea level (meter). Therefore, for example, the flight altitude h of the fighter P is obtained from the vertical coordinate PGy of the object coordinate origin PG and a given ratio.

FIG. 4 is a conceptual diagram for explaining the correction of the collision avoidance assisting process. As shown in FIG. 4A, in the ground attack mission, the target T on the ground L has already been bombed, and the robot is leaving. In the beginner mode, the flight altitude h of the fighter P is a predetermined judgment value, for example,
When the distance is 100 m or less, collision avoidance assistance processing is performed.

The collision avoidance assistance process in this embodiment is
It consists of speed correction and aircraft attitude correction. As shown in FIG. 4 (b), the speed correction is performed by adding the correction speed vector Vc upward to the vertical component speed vector Vv of the speed vector V of the fighter P (in this case, the falling speed). Thus, the descent speed is delayed, and the player gains time to perform the operation of raising the aircraft to avoid a collision.
The corrected velocity vector Vc is based on the relative altitude difference Δh between the fighter P and the ground in the traveling direction (position where collision is expected).
Determined by a given relationship. Although the descent can be eliminated (set to 0) by correcting the speed in the setting, the corrected speed vector Vc is, for example, the initial vertical component speed vector from the viewpoint of the flight simulation and the game. Keep it about 0.8 times Vv,
It is preferable to make a collision if the player does not perform any operation.

As shown in FIG. 4 (c), the aircraft attitude is corrected by raising the nose of the fighter P. As described above, the vertical component velocity vector Vv decreases due to the addition of the corrected velocity vector Vc. If the attitude of the aircraft remains the same, it may be possible to find out that the descent speed is artificially adjusted. Therefore,
Correct the nose upwards so that the apparent decrease in descent speed is as if it were associated with a climb operation. Also,
The correction of the aircraft attitude also has the effect of encouraging a beginner player to perform an operation of raising the fighter P.

[Description of Functional Blocks] Next, functional blocks for implementing the present embodiment will be described. FIG. 5 shows the first
It is a block diagram showing an example of a functional block in the embodiment of. In the figure, the functional block is the operation unit 1.
0, a processing unit 20, a display unit 30, and a storage unit 40.

The operation unit 10 selects the game difficulty level, the model of the fighter P operated by the player, the operation of the fighter P, the selection of the target T, the selection of the mission, and the attack weapon (for example, anti-ground missile). This is for inputting the firing timing of M). The operation input signal is output to the processing unit 20. The function can be realized by hardware such as a cross key, a lever, and a button. The operation input signal output from the operation unit 10 is transmitted to the processing unit 20.

The processing section 20 performs various arithmetic processes such as control of the entire game device, instructions to each functional block in the device, game operation, and the like. The function is, for example, a CPU (CI

Collision avoidance assistance unit 22
2 further includes a speed correction unit 224 and a posture correction unit 226 in the present embodiment.

The speed correction unit 224 corrects the descent speed of the fighter P to apparently delay the descent. Specifically, for example, when the fighter P has reached a predetermined altitude or lower, the predicted arrival position that will arrive several frames later is calculated by referring to the velocity vector V of the fighter P. The predicted arrival position is compared with the ground L to determine whether or not it is located on the ground L or below. If it is determined that the ground plane L or less is reached, the relative altitude difference Δh between the fighter P and the ground L at the predicted arrival position is calculated, and the corrected velocity vector Vc is calculated according to the altitude difference, and the velocity vector V is obtained. Add.

The attitude correction unit 226 corrects the attitude of the fighter P body so that the speed correction unit 224 does not make the game screen look unnatural as a result of the speed correction. Specifically, for example, when the vertical component velocity vector Vv is 0, the nose is raised in proportion to the corrected vertical component velocity vector Vv so that the aircraft becomes horizontal. Also, when correcting the posture, if the upper and lower sides of the aircraft are tilted, correct the roll to align the upper and lower sides of the ground with the upper and lower sides of the aircraft to assist a beginner player in calmly ascending operations. You may add. The model upgrade process and the roll correction process of the aircraft are performed by, for example, the fighter P.
It can be realized by rotating around the object coordinates of.

The image generating section 24 is realized by birdware such as a CPU, a DSP, an IC dedicated to image generation, and a memory, and generates image data based on an instruction signal from the game calculating section 22 and various coordinate information. To do. For example, it also includes brightness calculation which is a shading process, texture mapping process, and color interpolation process.

The display section 30 displays a game screen based on the image signal from the image generation section 24.
It can be realized by hardware such as RT, LCD, ELD, PDP, and HMD.

The storage section 40 is realized by hardware such as a CD-ROM, game cassette, IC card, MO, FD (R), DVD, IC memory, hard disk and the like. The storage section 40 stores a program for executing various in-game processes, and game information 42 including data such as setting values necessary for executing the program.

The game information 42 includes the collision avoidance assisting section 22.
2 includes a collision avoidance assistance program 422,

The object information 444 is created for each object placed in the game, and stores information describing the position and orientation of the object in world coordinates, or the motion. FIG. 6 is a diagram showing an example of the data structure of the object information 444 of the fighter P.
As shown in the figure, for example, the object ID, the coordinate value of the object coordinate origin PG and the model tip PT in world coordinates (hereinafter referred to as position coordinate), speed, acceleration, and rotation angles θx, θy, θ around the object coordinate axis.
z and the like are stored. Further, the position information, velocity, and acceleration are stored for a predetermined number of seconds at predetermined frame intervals in the ring buffer method for the replay mode.

The modeling data 446 is created for each object placed in the game and stores various settings relating to the shape of the object such as the shape of the object and the type of texture. The modeling data 446 also includes terrain related data.

[Explanation of Flow] Next, a flow of processing for collision avoidance assistance in the present embodiment will be described. Figure 7
It is a flowchart which shows the flow of a collision avoidance assistance process.
The flowchart shown in the figure is set to be effective only in the beginner mode, and is executed only for the fighter P operated by the player when the position coordinates of the object are updated for each frame.

In FIG. 7, first, the game calculation section 22
The movement of the body of the fighter P is calculated based on the operation of the player in the same manner as in the conventional case, and the control amount according to the operation amount such as position coordinates, speed, acceleration, and rotation angle is determined. Then, the position coordinates, velocity, acceleration, rotation angle, etc. of the object information 444 are updated based on the control amount (step S102). This stage is, so to speak, a stage of primary control, and the object information of the fighter P in that frame has not yet been determined.

Next, the game calculation section 22 obtains the flight altitude h and compares it with a predetermined judgment value (here, for example, 100 m) (step S104). If the fighter P is flying at or above the judgment value, that is, if it is flying at an altitude where there is no risk of collision, the process moves to the next viewpoint coordinate conversion process (step S1).
04 NO). On the other hand, when the flight altitude h is less than or equal to the determination value, the routine proceeds to a collision avoidance routine which is the secondary control (YES in step S104).

First, the speed is corrected. The velocity correction unit 224 calculates the velocity vector V from the object information 444.
Is obtained (step S106), and the predicted arrival position coordinates that will be reached after a predetermined frame when the speed is maintained are obtained (step S108). Next, the velocity correction unit 224 determines whether or not the ground L exists in the predicted moving direction of the fighter P by referring to the object information 444 of the ground L based on the previously obtained predicted arrival position coordinates. (Step S110).

When it is determined that the ground L is not present at the predicted arrival position (NO in step S110), it is determined that there is no risk of collision, and the process moves to the next viewpoint coordinate conversion process (step S120). When it is determined that there is no ground, for example, there is an entrance to an underground gallery, or the approach angle is almost horizontal. When it is determined that the ground L exists (YES in step S110), the speed correction unit 224 obtains the relative altitude difference Δh from the difference between the position coordinates of the ground L and the position coordinates of the fighter P (step S112).

Once the relative height difference Δh has been obtained, the vertical component velocity vector Vv of the velocity vector V is next calculated.
And a corrected velocity vector Vc is obtained (step S11
4). The corrected velocity vector Vc is, for example, the relative altitude difference Δ.
It is calculated from the given relationship based on h.

FIG. 8 is a diagram showing an example of the relationship between the relative altitude difference Δh and the corrected velocity vector Vc. Relative altitude difference Δh
And the corrected velocity vector Vc are based on an inversely proportional relationship,
Although it can be set as appropriate, it is effective to set so that the smaller the relative height difference Δh becomes, the more effective the correction becomes, as shown in FIG. Although the maximum value of | Vc | is 0.8 | Vv | in FIG. 8, it can be set as appropriate. However, for the purpose of flight simulation, it is preferable that the corrected velocity vector Vc collides with the player unless the player performs any operation.

When the vertical component velocity vector Vv and the corrected velocity vector Vc are obtained, the velocity correction unit 224
Combines the vertical component velocity vector Vv = Vv-Vc, updates the object information 444 of the fighter P, and ends the velocity correction (step S116).

Next, the attitude of the fighter P is corrected. The posture correction unit 226 corrects the expected posture according to the correction velocity vector Vc obtained in step S114 (step S118). For example, when the vertical component velocity vector Vv is 0, the nose is raised in proportion to the corrected vertical component velocity vector Vv so that the aircraft becomes horizontal. Regarding the nose raising process, for example, the fighter P
This can be realized by changing the rotation angle θx about the object coordinate X axis, but since it is known, the description thereof is omitted here. Further, at the same time, when the upper and lower sides of the machine body are tilted, a process of correcting the roll (rotation around the object coordinate Z axis of the machine body) and correcting the posture so that the upper and lower sides of the ground L and the upper and lower sides of the machine body are aligned is performed. If you do, it is kind and preferable to beginners. When the correction of the body attitude is completed, at this stage, in addition to the primary control according to the operation input of the player in step S102, the secondary control (correction) related to avoidance is executed, and the fighter P in the frame concerned is executed. This means that the object information 444 has been decided. The collision avoidance correction process ends, and the process moves to the next viewpoint coordinate conversion process.

Incidentally, the control amount according to the operation input by the player in step S102 is temporarily stored separately, and in the collision avoidance assistance routine, not the object information 444 but the control amount is corrected, and then the object information 444 is newly made.
May be updated based on the control amount.

The terminal connected to the network is not limited to the above-mentioned home game machine, but may be a personal computer, an arcade game machine, a mobile terminal such as a PDA, or the like. When the arcade game device is connected to the network, information can be exchanged with the arcade game device, and information can also be exchanged with the home game device. (Memory card, portable game device) may be used.

In the above description, it is assumed that the beginner mode is selected. However, due to the game structure,
If the beginner mode is not selected, whether or not the collision avoidance assist function is installed in the fighter P may be selected. Alternatively, it may be realized by setting a fighter plane for beginners that already has the same function.

Further, in the first embodiment, the ground or the ceiling is targeted for collision, but the present invention is not limited to this.

[Second Embodiment] Next, as a second embodiment, the present invention is applied to a case where a fighter P flies in a place where the horizontal direction is restricted by wall surfaces such as a valley or an underground tunnel. The applied example will be described. The second embodiment can be realized by the same function and hardware as those of the first embodiment, and the same elements are given the same reference numerals and the description thereof will be omitted.

[Explanation of Principle] FIG. 12 is a schematic view showing a state of flight in the present embodiment. In the figure, a fighter P operated by the player is flying in a narrow valley.
Both sides are regulated by the cliff CL, and it is a situation where speed sense and control skills are required. An advanced person who is accustomed to the operation can, for example, fly along the route C1 to proceed, but a beginner cannot adjust the steering timing and the flight speed appropriately because he / she is not used to the route C2. There are many cases where the vehicle hits the cliff CL without turning. Therefore, in the present embodiment, the horizontal collision avoidance assistance is performed on the cliff CL, as in the case of the ground surface in the first embodiment.

FIG. 13 is a diagram for explaining the correction when the collision avoidance assistance is applied to the cliff CL (horizontal obstacle). In the present embodiment, the velocity correction and the attitude of the aircraft are both horizontal components, object coordinates X-Z in the drawing.
The feature is that it is performed in the plane direction.

[Explanation of Flow] FIG. 14 is a flowchart showing a flow of collision avoidance assistance processing in the second embodiment. Similar to the first embodiment, this flow is set to be effective only in the beginner mode, and when the position coordinate of the object is updated for each frame,
It is executed only for the fighter P operated by the player.

In the same figure, the game calculation section 22 calculates the movement of the body of the fighter P based on the operation of the player in the same manner as in the conventional case, and according to the operation amount such as position coordinates, speed, acceleration and rotation angle. Determine the controlled variable. Then, based on the control amount, the position coordinates, speed, acceleration, rotation angle, etc. of the object information 444 are updated (step S20).
2). This stage is, so to speak, a stage of primary control, and the object information of the fighter P in that frame has not yet been determined.

Next, the speed correction section 224 acquires the speed vector V from the object information 444 (step S2).
04), the predicted arrival position coordinates that will be reached after a predetermined frame when the speed is maintained are obtained (step S206). Next, the velocity correction unit 224 determines the object information 444 of the cliff CL on the basis of the predicted arrival position coordinates obtained previously.
With reference to, it is determined whether or not there is a cliff CL in the predicted movement direction of the fighter P (step S208).

When it is determined that there is no cliff CL at the predicted arrival position, it is determined that there is no risk of collision, and the process moves to the next viewpoint coordinate conversion process (NO in step S208). When it is determined that there is a cliff CL (Y in step S208)
ES), the velocity correction unit 224 obtains an average normal vector of a plurality of polygons forming the cliff CL in the predicted moving direction (step S210). This average normal vector is
In the first embodiment, it suffices to simply prevent a fall, so it suffices to correct it in the vertical direction. However, since the cliff CL has a different surface orientation depending on the position, the cliff CL is required to handle this. That is, in order to reduce the influence of the fine irregularities (shape) of the cliff CL, the predicted arrival position determined in step S208 and the normal vector of a plurality of polygons in the vicinity are averaged. The selection of polygons for averaging may be appropriately set.

Next, the velocity correction unit 224 obtains the relative distance D from the difference between the position coordinates of the cliff CL and the fighter P (step S212), and obtains the average normal direction component velocity vector Vn from the velocity vector V ( Step S214). Then, based on the average normal direction component velocity vector Vn,
A corrected velocity vector Vc in the direction of the average normal vector n is obtained (step S216). The corrected velocity vector Vc is obtained based on a given relationship with the relative distance D, for example, from the same relationship as the relative altitude difference Δh shown in FIG. 8.

When the corrected velocity vector Vc is obtained, the velocity correction unit 22 synthesizes the average normal direction component velocity vector Vn = Vn-Vc, and then updates the object information 444 of the fighter P to determine the velocity. The correction ends (step S218).

Next, the attitude of the fighter P is corrected. The attitude correction unit 226 corrects the attitude of the machine body according to the correction speed vector Vc obtained in step S216 (step S220). For example, in the case where the average normal direction component velocity vector Vn is equal to the velocity vector V, it is proportional to the corrected average normal direction component velocity vector Vn so that the aircraft lies sideways by approximately 80 degrees, and is opposite to the vector. Turn the nose in the direction (toward the center of the valley).

When the correction of the body posture is completed, at this stage, the secondary control (correction) for avoidance is executed in addition to the primary control according to the operation input of the player in step S202, and the battle in the frame concerned. This means that the object information 444 of the machine P has been decided. The collision avoidance correction process ends, and the process moves to the next viewpoint coordinate conversion process.

The control amount corresponding to the operation input by the player in step S202 is temporarily stored separately, and in the collision avoidance assistance routine, the control amount is corrected instead of the object information 444, and then the object information 444 is newly corrected.
May be updated based on the control amount.

By the above collision avoidance assistance processing, the time until the fighter P crashes into the cliff CL is delayed, and the time for the player to steer the aircraft for collision avoidance is gained, thereby assisting the player. Can be Also,
Correct the nose so that it faces the center of the valley, and change the speed as if it were accompanied by steering. At the same time, it is possible to aim at an effect of encouraging a player who is a beginner to perform an avoidance operation such that the nose faces the center of the valley.

Although the present embodiment has been described with respect to the case where the fighter P flies in a narrow valley or the like, the present invention is not limited to this. For example, it can be applied to a relationship between a racing car and a guardrail in a car racing game in which the relationship between a moving object and a course is similar.

In the first and second embodiments, the fighter P is corrected to assist in collision avoidance, but the target of correction is not limited to the fighter P.

[Third Embodiment] Next, as a third embodiment, an example of assisting collision avoidance without correcting the fighter P in the same situation as the first embodiment will be described. The third embodiment can be realized by the same function and hardware as those of the first embodiment, and the same elements are given the same reference numerals and the description thereof will be omitted.

[Explanation of Principle] FIG. 15 is a diagram for explaining the outline of the collision avoidance assistance process in the present embodiment. In the figure, the fighter P operated by the player is in a leaving action after the target T is bombed. In the beginner mode, when the fighter P reaches the predetermined flight altitude h or less, the Y-axis coordinate (vertical coordinate) of the position coordinate of the ground L is subtracted by a given value to move it away from the fighter P. As a result, the time until the fighter P crashes into the ground is gained, and it is used as a collision avoidance aid. The collision avoidance assistance process is realized by the collision avoidance processing unit 222.

[Explanation of Flow] FIG. 16 is a flowchart showing a flow of collision avoidance assistance processing in the third embodiment. Similar to the first embodiment, this flow is set to be effective only in the beginner mode, and when the position coordinate of the object is updated for each frame,
It is executed only for the fighter P operated by the player.

In FIG. 16, first, the game calculation unit 22
Calculates the movement of the fighter P in the same manner as other objects, and updates the object information 444 of the fighter P (step S302). Next, the game calculation unit 22 obtains the flight altitude h, and a predetermined determination value (here, for example, 100
m) and compare (step S304)

When the fighter P is flying above the judgment value, that is, at an altitude where there is no fear of collision with the ground, the process proceeds to the next viewpoint coordinate conversion process (NO in step S304). On the other hand, when the flight altitude h is less than or equal to the determination value, the process proceeds to collision avoidance (YES in step S304).

First, the height of the ground is corrected (position correction). The collision avoidance assisting unit 222 obtains the velocity vector V from the object information 444 of the fighter P (step S306), and obtains predicted arrival position coordinates that will be reached after a predetermined frame when the velocity is maintained (step S306). S308). Next, the collision avoidance assisting unit 222 refers to the object information 444 of the ground L based on the coordinates of the predicted arrival position previously obtained, and determines whether or not the ground L is in the predicted movement direction of the fighter P. Judgment (step S31
0).

If it is determined that there is no ground at the predicted arrival position, it is determined that there is no danger of collision, and the process moves to the next viewpoint coordinate conversion process (NO in step S310). If it is determined that there is the ground (YES in step S310)
S), referring to the object information 444 of the ground L, the position coordinate Ly of the ground L is acquired (step S312).

Here, the position coordinate Ly is compared with a predetermined judgment value (for example, -200 (coordinate value)) to set the lower limit of the ground L to prevent the ground L from continuously falling (step S314). If it is less than or equal to the determination value (NO in step S314), the process proceeds to the next viewpoint conversion process without position correction. If it is larger than the judgment value (step S3
14), the position correction continues.

The collision avoidance assisting unit 222 obtains the relative altitude difference Δh from the difference between the position coordinates of the ground L and the fighter P (step S316), and determines the correction value Lc from the given relationship based on the relative altitude difference Δh. Obtained (step S318).
The correction value Lc is based on a given relationship with the relative altitude difference Δh, for example, the correction speed Vc and the relative altitude difference Δ shown in FIG.
It is obtained in the same manner as the relationship with h.

When the correction value Lc is obtained, the collision avoidance assisting unit 222 updates the object information 444 of the ground L by setting the position coordinate Ly = Ly−Lc of the ground L, and the speed correction is completed (step S320).

Next, the body posture of the fighter P is corrected. The collision avoidance assisting unit 222 corrects the attitude of the machine body according to the correction value Lc obtained in step S316 (step S322). For example, the vertical component velocity vector V
When the v is 0, the nose is raised in proportion to the corrected vertical component velocity vector Vv so that the aircraft becomes horizontal. Since the process of raising the nose is well known, its description is omitted here. Further, at the same time, if the upper and lower sides of the machine body are tilted, it is preferable and kind for beginners to correct the posture and correct the posture so that the upper and lower sides of the ground are aligned with the upper and lower sides of the machine body. When the correction of the body posture is completed, the process shifts to the next viewpoint coordinate conversion process.

In the above description of the present embodiment, the processing for lowering the position of the entire ground is performed, but it may be the minimum necessary portion. For example, FIG. 17 is a conceptual diagram showing an example of changing the position coordinates of a part of the ground to avoid collision. In the same figure, the viewpoint C is in a so-called cockpit view state where the viewpoint C is located in the cockpit of the fighter P or behind the fighter P. Therefore, since the ground displayed on the game screen is limited, the position of only the relevant portion is lowered.

In the first to third embodiments, the focus of the processing is to delay the collision between the fighter P and the object on the ground, but the hit determination is processed as usual. Therefore, although it is possible to delay the collision with the ground,
If the player himself does not perform the collision avoidance action, the collision is finally determined on the ground. However, there are cases where it is better to eliminate the collision itself.

[Fourth Embodiment] Next, as a fourth embodiment, an example of temporarily canceling (turning off) the collision determination between the fighter P and the ground will be described. The fourth embodiment can be realized by the same function and hardware as the first embodiment, and the same elements are given the same reference numerals and the description thereof will be omitted.

[Explanation of Principle] FIG. 18 is a diagram showing an example of the positional relationship between the fighter P and the hit check points. The fighter P is modeled by a polygon. Then, as in the conventional case, for example, a plurality of hit check points Hn (n is an integer) are provided at predetermined positions from the surroundings.
It is set so as to surround the airframe, and it is determined that there was a hit when another object (for example, a missile from an enemy aircraft, a building, the ground, etc.) is within a given distance from the hit checkpoint. The hit checkpoint Hn is
Since it is not drawn, it is not displayed on the game screen. Information on the hit check point Hn is stored in the modeling data 446.

FIG. 19 is a conceptual diagram for explaining the method of collision avoidance assistance processing in this embodiment. The collision avoidance assistance process is realized by the collision avoidance processing unit 222. In the figure, the fighter P operated by the player in the figure
Is in the departure behavior after the bombing of target T. In the beginner mode, when the fighter P reaches the predetermined flight altitude h or less, the hit determination of some or all of the hit check points Hn is canceled. Therefore, even if the leaving action is delayed and the fighter P collides with an object on the ground or reaches below the object on the ground, there is no hit determination and the game can be continued as it is. Note that if you are flying below the ground object forever, you will not be able to play a game. Therefore, if the fighter P reaches below the ground, you must forcibly correct the speed and attitude of the aircraft so that you can return to the sky. It may be encouraged.

[Explanation of Flow] FIG. 20 is a flow chart showing the flow of collision avoidance assistance processing in the fourth embodiment. Similar to the first embodiment, this flow is set to be effective only in the beginner mode, and when the position coordinate of the object is updated for each frame,
It is executed only for the fighter P operated by the player.

In the figure, first, the game calculation unit 22
The movement of the fighter P is calculated in the same manner as other objects, and the object information 444 of the fighter P is updated (step S402). Here, the collision avoidance assistance unit 222
The flight altitude h is obtained and a predetermined judgment value (here, for example, 1
00 (unit m)) (step S40)
4). If the fighter P is at or above the judgment value, that is, if there is a fear of collision at an intermediate altitude (N in step S404)
O), the hit determination process is validated, and the process moves to the next viewpoint coordinate conversion process (step S406). On the other hand, when the flight altitude h is less than or equal to the determination value (TE in step S404
S), the hit determination is invalidated and the hit determination process of the fighter P is canceled (step S408). Specifically, for example, the object information 444 of the fighter P is provided with a flag for hit determination cancellation, and ON / OFF of the hit determination is designated by the flag operation. If the hit determination process is canceled, the process moves to the next viewpoint conversion process, and the collision avoidance assistance process ends.

According to the above processing according to the present embodiment, the game over due to the collision of the ground is virtually eliminated.
You can concentrate on the fun of the original aerial battle and bombing of fighter games.

In the fourth embodiment, the height of the ground is changed or the hit judgment is canceled as a collision avoidance aid, but if the player replays as it is in the replay mode, the screen where the fighter dives to the ground is displayed. , Correct accordingly.

[Fifth Embodiment] Next, in a fifth embodiment, an example of replay of a scene subjected to collision avoidance processing will be described. This embodiment is a process at the time of replay, and is preferably realized together with the fourth embodiment, for example. The same elements as those in the first to fourth embodiments are designated by the same reference numerals, and the description thereof will be omitted.

FIG. 21 is a conceptual diagram for explaining the principle of processing of this embodiment. In the figure, it is assumed that the fighter P operated by the player has not sufficiently left the target T after the bombing, and has passed through the route C2, for example. Information such as position coordinates, speed, and acceleration of the fighter P at points PG0 to PG8 when passing the route C2 is the object information 44.
It is assumed that 4 is stacked. Point PG
0 to PG8 are, for example, fighter planes P for a predetermined number of frames
And the interval is appropriately set. In the replay mode, if the route C2 is reproduced as it is, an unnatural screen appears on the game screen where the fighter P dives back to the ground and reappears. Therefore, for example, the route C3 in which the fighter P does not contact the ground is corrected and replayed.

[Explanation of Functional Block] FIG. 22 is a functional block diagram showing a functional configuration of the fifth embodiment. The game calculation section 22 includes a trajectory correction section 228. The trajectory correction unit 228 is executed according to the trajectory correction program 428 stored in the storage unit 40, and corrects so as to draw the route C3. Specifically, for example, the object information 444
The point PGmin having the lowest altitude is obtained by referring to the position coordinates of the points PG0 to PG8 stacked in the above. Then, PGmin is corrected to a predetermined altitude. The same correction amount as this corrected amount is added to the position coordinates of other points. That is, the position of all the points is raised.

[Explanation of Flow] FIG. 23 is a flowchart showing a flow of processing at the time of replay in the present embodiment. In the figure, when the replay mode is executed,
The trajectory correction unit 226 sets the object information 44 of the fighter P.
4, the stacked points PG0 to PG8
The position information of is acquired (step S502). And
It is determined whether the position coordinates of each point are 0 or less (below the ground) (step S504).

If none of the points PGn is 0 or less, the process goes to the next viewpoint conversion process (step S).
504 NO). If there is a point PGn that is 0 or less (YES in step S504), the trajectory correction unit 226.
Finds the lowest point PGmin (step S506).

Next, the correction coordinate value ΔY necessary for setting the point PGmin to a predetermined altitude, for example, 10 m is obtained (step S508). Then, the correction coordinate value ΔY is added to all the stacked points PG0 to PG8, and the trajectory correction is completed (step S510).

[0121]

As described above, according to the present invention, when a moving object operated by a player approaches a real estate object, it assists in avoiding a collision and suppresses a penalty due to a collision determination, so that even a beginner can use it. You can fully enjoy the game.
