Next, a method for obtaining the display coordinates of the character described above will be described. First, the position of the character warrior in the virtual space in the game is given as position coordinates (Xw, Yw, Zw) in three-dimensional coordinates (world coordinate system) in the virtual space. The position of a background such as a fixed object other than the character warrior in the virtual space is also given as position coordinates in the world coordinate system. Then, the movement of the character warrior in the virtual space is processed as a change in the position coordinates of the world coordinate system. Specifically, the position coordinates of the character warrior are
The calculation is performed by the CPU 101 based on the information on the movement amount and the movement direction included in the operation signal from the operation unit 3 or the like.

On the other hand, the image displayed on the display 2 is displayed as a two-dimensional image in a predetermined direction from the coordinates (viewpoint coordinates) of one point in the world coordinate system in the three-dimensional virtual space. This gives the player a feeling as if a video camera is installed at a predetermined position in the virtual space and an image captured by the video camera is displayed on a display.

For example, when character warriors C1 and C2 are arranged in a three-dimensional virtual space as shown in FIG. 4, the position coordinates of the character warrior are determined by the position coordinates (Xw, Yw, Zw) in the world coordinate system. Is done. Then, the viewpoint coordinates P (XwP, YwP, ZwP) are, for example, as shown in FIG.
1 is set to the viewpoint coordinate P obliquely above and behind, and the sight line direction R from the viewpoint coordinate P is, for example, the gazing point coordinate near the upper part of the own device C1 (for example, a position slightly higher than the head of the own device C1) It is set in the direction of Q (XwQ, YwQ, ZwQ). In addition, in the drawings described below including FIG. 4, a mark of the virtual video camera V is written at the position of the viewpoint coordinate P for easy understanding.

The coordinates of each character warrior in the world coordinate system are determined by the coordinate setting means shown in FIG.
, A viewpoint coordinate system (Xv,
Yv, Zv), and further converted to a two-dimensional screen coordinate system (Xs, Ys) by a predetermined projection conversion process by the rendering processing unit 105 in FIG. 3 for display on the display screen.

The viewpoint coordinates P and the line-of-sight directions R in the world coordinate system, and the two-dimensional image displayed on the display 2 corresponding to the viewpoint coordinate system based on the viewpoint coordinates P will be described in more detail.

FIG. 5 is a diagram showing ordinary viewpoint coordinates P and line-of-sight directions R in the virtual space. FIG. 5 (a) and FIG.
(B) is a view of the virtual space viewed from directions D1 and D2 in FIG. 4, respectively. In the figure, the distance L between the own aircraft C1 and the enemy aircraft C2 in the world coordinate system is
The distance is longer than a predetermined distance L1, which is the distance between the boundaries of the proximity zone in which the two fight each other. In this case, the viewpoint coordinates P1 are obliquely above and behind the own device C1 as shown in the figure. Specifically, the viewpoint coordinates P1 are the gazing point coordinates Q1 at a position of a predetermined height H1 in the Yw direction, which is the height direction from the lower end position of the own device C1.
Are coordinates separated by a distance M1 from. The viewing direction R1 from the viewpoint coordinates P1 to the gazing point coordinates Q1 is downward at an angle θ1 with respect to the horizontal. The angle θ1 is, for example, 10 degrees.

FIG. 6 shows a screen of the display 2 corresponding to FIG. As shown in FIG. 6, the own aircraft C1 and the enemy aircraft C
When 2 is more than the predetermined distance L1, the enemy aircraft C2 is displayed on the display 2 without overlapping with the own aircraft C1.

On the other hand, FIGS. 7A and 7B show the own device C1.
FIG. 6 is a diagram corresponding to FIGS. 5A and 5B when the enemy aircraft C2 and the enemy aircraft C2 are approaching, respectively. According to FIG. 5A, the distance L between the own aircraft C1 and the enemy aircraft C2 is shorter than the predetermined distance L1. The screen displayed on the display 2 in this case is:
As shown in FIG. 8, the enemy aircraft C2 overlaps with its own aircraft C1 in front of the screen. Therefore, the player cannot see the movement of the enemy aircraft C2 in the portion hidden by the own aircraft C1 on the display.

[First Embodiment] Therefore, in the first embodiment of the present invention, the own device C1 in the virtual space is used.
When the distance L between the enemy aircraft C2 and the enemy aircraft C2 is shorter than the predetermined distance L1 and the enemy aircraft C2 overlaps the own aircraft C1 on the screen, as described in detail below, the viewpoint coordinates P are changed to change the screen coordinates. The above is displayed so that they do not overlap.

FIGS. 9A and 9B show the distance L between the own aircraft C1 and the enemy aircraft C2 in the first embodiment of the present invention.
7 is a diagram showing the viewpoint coordinates P and the line-of-sight direction R when is short, and corresponds to FIGS. 7A and 7B, respectively. According to FIGS. 9A and 9B, the viewpoint coordinates P2 in this case are obtained by calculating the distance M from the gazing point coordinates Q2 at a height H2 higher than the predetermined height H1 from the lower end position of the own device C1.
These coordinates are separated by a distance M2 shorter than 1. Then, the line-of-sight direction R2 from the viewpoint coordinates P2 to the gazing point coordinates Q2 is an angle θ2 (for example, 40
Degree) downward.

FIG. 10 shows a display 2 corresponding to FIG.
The screen of FIG. As described above, since the angle of the line-of-sight direction R2 is larger than the line-of-sight direction R1, the viewpoint coordinates P2 are higher in the height direction (Yw direction in FIG. 4) than the viewpoint coordinates P1. Therefore, the image displayed on the display 2 is an image looking down from the viewpoint coordinates P2.

As described above, the image displayed on the display 2 is an image looking down on the virtual space, so that the own device C1 and the enemy device C2 are displayed without overlapping.

Therefore, the player can clearly see the movement of the enemy aircraft, and can quickly respond to an attack from the enemy aircraft even when the two approach and perform a fighting fight. Becomes

The angle θ2 is different between the own aircraft C1 and the enemy aircraft C.
When the distance L from the distance 2 becomes shorter than the predetermined distance L1, the distance L changes according to the distance L. That is, when the own aircraft C1 is moving while approaching the direction of the enemy aircraft C2, the distance L reaches the predetermined distance L1, and when the distance L becomes shorter than the predetermined distance L1, the angle becomes smaller as the distance L between the two becomes shorter. θ2 increases and the viewpoint coordinates P2 rise. An expression for obtaining the angle θ2 is shown below. θ2 = arctan (A1 / L) (1) where A1 is a predetermined constant. Further, as shown in FIG. 2B, for example, when the own machine C1 is squatting and in a low posture, a constant A2 smaller than the constant A1 is used.

Further, the angle θ2 obtained by the above equation (1) is equal to a predetermined maximum angle θmax (for example, 40 °).
Degrees), the angle θ2 is, for example, the maximum angle θma
Set to x. This is for the following reason. That is, when the angle θ2 is larger than the maximum angle θmax, the viewpoint coordinates P are in the vicinity immediately above the own device C1. Then, it becomes difficult for the player to recognize the three-dimensional sense of distance in the image of the virtual space displayed on the display, and for example, it is difficult to distinguish an attack from the upper stage or the lower stage of the enemy aircraft C2. Therefore, in order to prevent the player from feeling such discomfort, the maximum angle θmax, which is the upper limit of the angle θ2, is set.

Further, as shown in FIG. 7B, for example, as shown in FIG. 7B, when the own aircraft C1 is facing the direction of the enemy aircraft C2, the distance L between the two is smaller. Applied. On the other hand, for example, as shown in FIG. 5B, when the own aircraft C1 is not facing the direction of the enemy aircraft C2, the direction in which the own aircraft C1 faces from the center coordinates (not shown) of the own aircraft C1. The distance from E1 to the point S where the direction E2 orthogonal to the enemy aircraft C2 intersects with the enemy aircraft C2 is used as the distance L between the two.

When the own aircraft C1 is approaching the enemy aircraft C2 at a speed higher than the normal speed and the distance L between the two is shorter than the predetermined distance L1, the line of sight R is set during the high-speed movement. Is set to an angle smaller than the angle θ2 obtained by the above equation (1) (for example, an angle about half of θ2). Then, when the own machine C1 stops, the line-of-sight angle θ is set to the angle θ2 obtained by the above equation (1). That is, the own machine C1
Is moving at high speed, the amount of change in the viewing angle θ is limited. This is because the line-of-sight angle θ is set to the above (1) during high-speed movement.
When the viewpoint coordinate P rises according to the formula, the own machine C
This is because the feeling of speed of the movement of 1 is impaired.

Therefore, while the own machine C1 is moving at high speed, a predetermined limit is set on the angle θ2 obtained by the above equation (1), and after the own machine C1 stops, the viewpoint coordinates P2 are obtained by the above equation (1). Is set to the coordinates corresponding to the angle θ2.

In FIG. 9A, the viewpoint coordinates P2
A distance M2 between the target point and the gazing point coordinate Q2 is shorter than the normal distance M1. When the line-of-sight angle θ increases and the viewpoint coordinate P increases, the area of the image of the character warrior displayed on the display decreases, and the detailed operation of the character warrior becomes difficult to understand. Therefore, when the two approaches and the line-of-sight angle θ increases, the distance between the viewpoint coordinates P2 and the gazing point coordinates Q2 is shortened so that the display areas of the own aircraft C1 and the enemy aircraft C2 on the display are not reduced.

At this time, when the distance L between the two is shorter than the distance L1, when the distance M1 is switched to the distance M2, the image on the display is suddenly switched, and the player watching the image feels strange. give. Therefore, the distance M
The change from 1 to the distance M2 takes a certain time T1.
As a result, the image is displayed substantially as if the camera zoom was performed, and the player does not feel uncomfortable.

Further, the own aircraft C1 moves at high speed and the enemy aircraft C2
When the distance L between the two becomes shorter than the distance L1, it takes a time T2 (for example, a time 20% shorter than T1) earlier than the predetermined time T1 to produce a sense of speed. To the distance M2.

Further, when the distance L between them is shorter than the predetermined distance L1, the height of the gazing point coordinate Q also becomes the height H as described above.
It rises from 1 to the height H2. The reason is as follows. That is, as described above, the distance L between them is the predetermined distance L1.
If it is shorter, the viewing angle θ is increased, and the viewpoint coordinates P are raised so that the two do not overlap. At this time, if only the line-of-sight angle θ is increased without changing the height of the gazing point coordinate Q so that the two do not overlap, the line-of-sight angle θ must be increased more than necessary. The line-of-sight angle θ cannot be increased without limit because the maximum angle θmax is set for the above-described reason.

Therefore, by raising the line-of-sight angle θ and raising the height of the gazing point coordinate Q to a height H2 higher than the height H1, the height of the viewpoint coordinate P can be increased without increasing the line-of-sight angle θ more than necessary. Is increased, it is possible to prevent the two displays from overlapping.

When the viewpoint coordinates P are set in advance, the gazing point coordinates Q may be obtained based on the angle θ2 obtained by the above equation (1).

By the way, when both are in the proximity area, the enemy aircraft C2 may come behind the own aircraft C1. FIG.
(A) and (b) are views of the virtual space viewed from the directions D1 and D2 in FIG. 4 when the enemy aircraft C2 is behind the own aircraft C1. FIG. 12 is an example of an image displayed on the display in such a case. According to FIG. 12, the enemy aircraft C2 is displayed before the own aircraft C1. The viewpoint coordinates P and the line-of-sight angle θ in such a case are set, for example, as follows.

That is, since both are in the proximity area, from the viewpoint from the ordinary viewpoint coordinates P1 in FIG.
Are displayed on the display 2 in an overlapping manner as shown in FIG. However, in the case of FIG. 12, the enemy aircraft C2
Is displayed, so that the enemy aircraft C2 is not hidden by the own aircraft C1 as in the case of FIG. On the other hand, own machine C1
Is operated by the player's own operation, so that there is no hindrance to the operation of the player even if the figure of the player's own machine C1 is not seen to some extent by the enemy machine C2.

Accordingly, in such a case, it is not necessary to increase the line-of-sight angle θ too much, and it is not necessary to change the line-of-sight angle θ as finely as in the above equation (1) according to the distance L between the two. Therefore, in such a case, FIG.
As shown in the figure, for example, the viewpoint coordinate P3 is
The angle is set to a position above 1 from an angle θ3 (the angle θ3 is, for example, 22 degrees) slightly larger than the angle θ1 in the normal case. Then, the line-of-sight angle θ3 in the line-of-sight direction R3 is fixed without being changed in response to a change in the distance L between the two in the proximity area.

The distance M3 between the viewpoint coordinates P3 and the gazing point coordinates Q1 is set to a distance M3 longer than the distance M1 in FIG. This is to prevent the display area of the enemy aircraft C2 displayed on the front side from increasing on the screen displayed on the display 2.

FIG. 13 is a flowchart for setting the viewpoint coordinates P corresponding to the distance between the own aircraft C1 and the enemy aircraft C2. According to FIG. 13, first, in step S1,
It is determined whether the distance L between the own device C1 and the enemy device C2 is within a predetermined distance L1. If the interval L is longer than the predetermined distance L1 in step S1, the process proceeds to step S5.

That is, step S5 corresponds to the case of FIG. 4 described above, and the viewpoint coordinates P are the height H1 from the lower end position of the own device C1.
Are coordinates M1 away from the gazing point coordinates Q1 by a distance M1, and further from the gazing point coordinates Q in the direction behind the own device C1 by an angle θ1 with respect to the horizontal.

On the other hand, if the interval L is within the predetermined distance L1 in step S1, then it is determined in step S2 whether the enemy aircraft C2 is behind the own aircraft C1.
If it is determined in step S2 that the enemy aircraft C2 is behind the own aircraft, the process proceeds to step S8.

That is, step S8 is the case of FIG. 11 described above, and the viewpoint coordinates P are separated from the lower end position of the own device C1 by a distance M3 from the gazing point coordinates Q1 of the height H1, and further from the gazing point coordinates Q1. The coordinates P3 are angles θ3 higher than the horizontal in the direction behind the machine C1.

Further, in step S2, the enemy aircraft C2
Is located in front of the own device C1, the process proceeds to step S3.
That is, step S3 is the case of FIG. 9 described above, and the angle θ2 is calculated based on the above equation (1). If the calculated angle θ2 is smaller than the maximum angle θmax,
Proceeding to step S7, the viewpoint coordinates P are separated from the gazing point coordinates Q2 set at the height H2 higher than the height H1 by a distance M2, and further from the gazing point coordinates Q2 with respect to the horizontal direction behind the own device C1. This is the coordinate P2 at which the obtained angle θ2 has increased.

The calculated line-of-sight angle θ is the maximum angle θ
If it is not less than max, the process proceeds to step S6, where the viewpoint coordinates P
Is the gazing point Q2 set to the height H2 higher than the height H1.
From the point of sight Q2
1 is set to the coordinate P2 which is higher than the horizontal by the maximum angle θmax in the direction behind.

Further, in the embodiment of the present invention, the viewpoint coordinates or the gazing point coordinates are obtained by calculation from the above equation (1), but these coordinates may be obtained without calculation. Good. For example, predetermined storage means (for example, the ROM 10 in FIG.
In 2), a table of viewpoint coordinates or gazing point coordinates set in advance according to the interval between them may be stored.

In the above embodiment of the present invention, for example, the number of enemy aircraft C2 is not limited to one, and a plurality of enemy aircraft C2 may exist.
In such a case, for example, the viewpoint coordinates or the gazing point coordinates may be switched according to the distance between the intermediate position of the plurality of enemy aircraft and the own aircraft C1.

The embodiment of the present invention is not limited to the above-mentioned battle game. For example, display 2
In a ski game in which virtual skiers are operated to perform virtual skiing, the viewpoint coordinates or the gazing point coordinates may be switched according to the distance between the skier and an obstacle.

[Second Embodiment] Next, a second embodiment of the present invention will be described. In the above-mentioned battle game in which the own aircraft C1 and the enemy aircraft C2 compete in a virtual space, a “ground stage” in which a character warrior battles on a predetermined ground set in the virtual space, and a character warrior in a three-dimensional space A "space stage" is set up to fight in a virtual space such as outer space where you can move to any position. These two stages are switched as the player selects or the game progresses. In the present embodiment, the position of the camera V (that is, viewpoint coordinates P and gazing point coordinates Q) is switched according to the set stage.

Here, the manner of movement of the own machine C1 by the operation of the player will be described. As the movement mode of the own device C1, a "normal mode" and a "dash mode" described below are set. The “normal mode” is set by the player operating the lever of the operation unit 3 without pressing the button of the operation unit 3. In the "normal mode", the own machine C1 moves at the speed v1 in the direction in which the lever is tilted while the lever is tilted.

On the other hand, the "dash mode" is set when the player operates the lever while pressing the button. In the “dash mode”, the own machine C1 moves at a speed v2 higher than the speed v1 in a direction in which the lever is tilted while the lever is tilted. As described above, the player operates the own machine C1 and battles with the enemy machine C2 while properly using the two modes in which the moving speed of the own machine C1 is different.

FIG. 14 is a diagram for explaining the position of the camera V when the virtual space is the “ground stage”.
FIG. 15 is a diagram of the virtual space corresponding to FIG. 14 as viewed from above, and is a diagram illustrating a viewpoint coordinate P, a gazing point coordinate Q, and a line-of-sight direction R. As shown in FIG. 15, when the own aircraft C1 is stationary facing the enemy aircraft C2 at the “ground stage”, an image from the camera position V1 is displayed on the display 2. That is, the viewpoint coordinates P _V1 are set behind the own device C1 as in the above-described embodiment.
Viewing direction R _V1 from the viewpoint coordinates P _V1 is set to, for example, the direction of the gazing point coordinate Q _V1 of a location of the terminal C1. That is, the line-of-sight direction R is a forward direction of the own device C1. Therefore, on the display 2, the own device C1 is displayed in front of the screen and the enemy device C2 is displayed in the back of the screen as in FIG.

Further, when the own machine C1 moves in the "normal mode" or the "dash mode", the own machine C1
Turns in the direction of travel. Therefore, an image from the camera position V2 is displayed on the display 2. That is, even when the own device C1 moves, as shown in FIG. 15, the viewpoint coordinates _V2 P are set backward with respect to the traveling direction of the own device C1, and the gazing point coordinates Q _V2 are the position of the own device C1. , The line-of-sight direction R _V2 is the forward direction of the own aircraft C1, that is, the traveling direction (in the figure,
For example, the own aircraft C1 moves in the “dash mode” to the right with respect to the enemy aircraft C2). Therefore, when moving in a direction different from the direction in which the enemy aircraft C2 is present, the enemy aircraft C2 disappears from the screen of the display 2.

As described above, when the own aircraft C1 moves in the left-right direction with respect to the enemy aircraft C2, the enemy aircraft C2 disappears from the screen. However, in the “ground stage”
Both the own aircraft C1 and the enemy aircraft C2 are arranged on the virtual ground, and are limited to movement on the ground.
Even if disappears, the player can relatively easily find the position of the enemy aircraft C2. That is, the player can always find the enemy aircraft 2 by changing the direction of the own aircraft C1 and looking 360 degrees on the ground.

FIG. 16 is a diagram showing the position of the camera V when the virtual space is the “space stage”. FIG. 17 is a diagram of the virtual space corresponding to FIG. 16 when viewed from above, and is a diagram for explaining the viewpoint coordinates P, the gazing point coordinates Q, and the line-of-sight direction R. As shown in FIG. 17, even in the “space stage”, the own aircraft C1 is in the position of the enemy aircraft C2.
When the camera is stationary while facing the camera, an image from the position of the camera V1 is displayed on the display 2. That is, similarly to the “ground stage”, the viewpoint coordinates P _V1 are set behind the own device C1, the gazing point coordinates Q _V1 are set at the position of the own device C1, and the line-of-sight direction R
_V1 is set forward of the own device C1.

By the way, in the "space stage",
The enemy aircraft 1 and the enemy aircraft C2 can move freely in the three-dimensional space. Therefore, unlike the above-mentioned “ground stage”, it is possible to freely move not only in the horizontal direction but also in the vertical direction, for example. In such a case, if the same viewpoint coordinates P and gazing point coordinates Q as those of the “ground stage” are set, the own device C1
When the direction of the own device C1 changes with the movement of, the viewpoint coordinates P and the line of sight direction R also change (see the position of the camera V2 in FIG. 15), and the enemy device C2 disappears from the screen of the display 2.

However, unlike the above-mentioned "ground stage", in the "space stage", once the enemy aircraft C2 is lost, it is difficult to find the position of the enemy aircraft C2.
This is because the player needs to search for the enemy aircraft C2 over the entire virtual space that is a three-dimensional space.

In particular, when the own machine C1 moves in the "dash mode" in which it moves faster than the "normal mode",
Since the distance between the own aircraft C1 and the enemy aircraft C2 in the virtual space is rapidly separated in a short time, it is more difficult to search for the position of the enemy aircraft C2 after the movement is completed.

Therefore, in the second embodiment,
In the “space stage”, the own aircraft C 1
Enemy aircraft C2 disappears from the screen when moving
As described above, the viewpoint coordinates P and the gazing point coordinates Q are set. Ingredient
Physically, it is shown at the position of the cameras V2 and V3 in FIG.
Thus, the own aircraft C1 and the enemy aircraft C2 are in the line-of-sight directions R, respectively._V2, R
_V3Viewpoint coordinates P so that they are placed one above the other_V2, P_V3Passing
And attention point coordinates Q_V2, Q _V3Is set.

More specifically, the viewpoint coordinates P _V2 , P
_V3 is one of coordinates constituting the enemy aircraft C2 or coordinates in the vicinity thereof (preferably, coordinates near the waist of the enemy aircraft C2).
A line segment extending between the coordinates constituting the own device C1 or one of the coordinates in the vicinity thereof (preferably, one coordinate above the head of the own device C1) is extended toward the own device C1. Set on a straight line.

The gazing point coordinates Q _V2 and Q _V3 are set on the line segment or on a straight line extending the line segment toward the enemy aircraft C2, and are, for example, coordinates near the waist of the enemy aircraft C2. . Therefore, since the line-of-sight directions R _V2 and R _V3 from the viewpoint coordinates P _V2 and P _V3 respectively point in the direction in which the enemy aircraft C2 is located,
The enemy aircraft C2 does not disappear from the screen of the display 2. In addition, since the own device C1 is in front of the enemy device C2 in the line-of-sight directions R _V2 and R _V3 , the image of the own device C1 is also displayed on the screen of the display 2.

After the movement of the own device C1 is completed, the own device C1
1 stands still in the direction of the enemy aircraft C2, so that even after the movement is completed, the viewpoint coordinates P are set behind the own aircraft C1 and the gazing point coordinates Q are set at the position of the own aircraft C1, the gaze direction is not changed. Since the enemy aircraft C2 is placed on R, the enemy aircraft C2 does not disappear from the screen.

Therefore, even if the enemy aircraft C2 disappears from the screen during the game, the player moves the enemy aircraft C1 in the "dash mode" to thereby cause the enemy aircraft C2 to move.
2 can be displayed on the screen.

FIG. 18 shows a screen of the display 2 corresponding to the cameras V1, V2 and V3 in FIGS. FIG. 18A shows an image from the camera V1, in which the own aircraft C1 faces the enemy aircraft C2 and is stationary, as in FIG. In FIGS. 18B and 18C,
The images are from the cameras V2 and V3, respectively, and the own device C1 is moving in the “dash mode” to the right of the screen. At this time, the viewpoint coordinates P are not set behind the own aircraft C1, and as described above, a line connecting the position of the enemy aircraft C2 and the own aircraft C1 is drawn on a straight line extending toward the own aircraft C1. Yes,
The gazing point coordinates Q are at the position of the enemy aircraft C2.

Therefore, even when the own aircraft C1 moves, the figure of the enemy aircraft C2 is always almost at the center of the screen and does not disappear from the screen. Further, the own device C1 is also displayed on the lower side of the screen. Therefore, the player can move his own aircraft C1 in the “dash mode” while grasping the position of the enemy aircraft C2. Can resume the battle. In this way, the player can enjoy the battle with the enemy aircraft C2 for more time for the limited game time.

FIG. 19 is a flowchart of the second embodiment. If there is a lever operation in step S1, and if there is a button input in step S2, the "dash mode" movement is performed. At this time, it is further determined in step S3 whether the stage of the game currently in progress is “space stage” or “ground stage”.

In the case of the "space stage", in step S4, as described above, the viewpoint coordinates P are set on the line connecting the enemy aircraft C2 and the own aircraft C1 so that both are displayed on the screen. The gazing point coordinate Q is set to the position of the enemy aircraft C2.

On the other hand, if no button input is performed in step S2 (ie, "normal mode"), and if the "ground stage" is determined in step S3, the normal viewpoint coordinates P and the gazing point are determined in step S5. The coordinates Q are set. That is, the viewpoint coordinates P are set behind the own device C1, and the gazing point coordinates Q are set at the position of the own device C1. Therefore, the line-of-sight direction R is the traveling direction of the own device C1.

In the above-described embodiment, in the “space stage”, the own machine C1 is set in the “normal mode”.
, The viewpoint coordinates P and the gazing point coordinates Q in the “dash mode” described above may be set.

As described above, in the "space stage", even when the own aircraft C1 moves, the enemy aircraft C2 does not disappear from the screen as in the "ground stage". Does not lose sight of the enemy aircraft C2.

Further, the enemy aircraft C2 may move while the own aircraft C1 is moving. At this time, at the viewpoint coordinates P and the gazing point coordinates Q described above, even if the enemy aircraft C2 is moving, the enemy aircraft C2
Is always located at the center of the screen, so the moving direction of the enemy aircraft C2 is unknown. Therefore, when the enemy aircraft C2 also moves while the own aircraft C1 is moving, it is preferable to shift the display position of the enemy aircraft C2 by a predetermined distance in the moving direction. Therefore, when the enemy aircraft C2 moves, the gazing point coordinates Q are shifted by a predetermined distance in the direction opposite to the moving direction. Accordingly, the position of the enemy aircraft C2 displayed on the screen is shifted from the center of the screen in the moving direction, so that the player can easily grasp the moving direction of the enemy aircraft C2.

[Third Embodiment] Next, a third embodiment of the present invention will be described. In a fighting game played in a virtual space, one game as in the above-described embodiment is performed.
In addition to the one-on-one match, there is a one-to-many match game described in the third embodiment.

For example, when a one-to-many fighting game is played by a fighting game, a self-character C1 operated by the player and a plurality of enemy characters are displayed on the screen. At this time, the direction of the camera V (that is, the line-of-sight direction R defined by the viewpoint coordinates P and the gazing point coordinates Q) is determined in the third embodiment as described below. It is set based on the positional relationship of the enemy character.

FIG. 20 is a diagram showing the direction of the camera V when the distance between one's own character and a plurality of enemy characters in the virtual space is large. Specifically, of the plurality of enemy characters C2, C3, and C4, the distance between the enemy character C2 closest to the own character C1 and the own character C1 is greater than a predetermined radius r (for example, 3.5 m in the virtual space). If you are away. The distance to the enemy character C2 closest to the self-character C1 is selected because the closest character C2 is the self-character C1.
This is because the character is likely to approach first and fight.

In such a case, the camera V is positioned at a position where the self-character C1 and the enemy character C2 are arranged in front and behind in the line-of-sight direction Ra. That is, on the screen, the self-character C1 is displayed in the foreground,
Gaze direction R so that enemy character C2 is displayed on the back side
a is set. More specifically, the viewpoint coordinates Pa are in the height direction (Yw direction) from the lower end position of the self-character C1.
Is set on a straight line extending in the direction opposite to the direction to the closest enemy character C2 from the gazing point coordinates Qa of the predetermined height Ha. The angle of the line of sight Ra from the viewpoint coordinates Pa to the gazing point coordinates Qa with respect to the horizontal is an angle θa downward with respect to the horizontal. The angle θa is, for example, 12.5 degrees.

FIG. 21 is a diagram showing an example of the screen of the display 2 corresponding to FIG. As shown in FIG. 21, by viewing the virtual space from the line of sight Ra, the self-character C1 is displayed on the near side of the screen, and a plurality of enemy characters C2, C3, C4 are displayed on the far side of the screen.

Since the self-character C1 is displayed in front of the screen in this manner, the player can see on the screen almost the same image as the virtual space that the self-character C1 is watching. And a more natural image can be obtained. further,
It is possible to display a plurality of distant enemy characters on the screen without displaying the image of the self-character C1 in a small size.

Next, FIG. 22 is a diagram showing the direction of the camera V when the distance between the self character and a plurality of enemy characters is approaching in the virtual space. In particular,
Of the plurality of enemy characters C2, C3, C4, the distance between the enemy character C2 closest to the own character C1 and the own character C1 is, for example, the predetermined radius r (3.5).
m).

In such a case, the camera V is positioned at such a position that the enemy character C2 closest to the self C1 character and the enemy character C2 are located on the left side (right side) and right side (left side) with respect to the line of sight. That is, the viewing direction Rb is set so that the self-character C1 and the closest enemy character C2 are displayed side by side on the screen.

More specifically, the viewpoint coordinates Pb are the height H
It is set on a straight line extending in a direction substantially perpendicular to the line segment S from the gazing point coordinate Qb which is the middle point coordinate of the line segment S connecting the self character C1 and the closest enemy character C2 at the height of b. Further, the line-of-sight direction Rb from the viewpoint coordinates Pb to the gazing point coordinates Qb is downward at an angle θb with respect to the horizontal. Angle θ
b is about 12.5 degrees, which is the same as the angle θa.

The height Hb is set lower than the height Ha by a predetermined height ΔH (for example, 1 m in a virtual space). As a result, the heights of the viewpoint coordinates Pb and the gazing point coordinates Qb are also set lower by the predetermined height ΔH. Therefore, the line-of-sight direction R
b is a predetermined height Δ from the line-of-sight direction Rb ′ when it is assumed that the line-of-sight direction is switched at the height Ha in the line-of-sight direction Ra.
H becomes lower. This is for the following reason.

That is, for example, in FIG. 22, although not the closest enemy character C2, it exists within the predetermined radius r,
In some cases, there is an enemy character C5 that is very close to the camera V. In such a case, if the line-of-sight direction Rb is high, the enemy character C5 may be out of the shooting range of the camera V and may not be displayed on the screen even though the enemy character C5 is within the predetermined radius r.

FIG. 23 is a view showing the photographing range of the camera V in the virtual space. As shown in FIG. 23, when the enemy character C5 exists in the immediate vicinity of the camera V, the enemy character C5 can be photographed in the photographing range W in the line-of-sight direction Rb, so that the enemy character C5 is displayed on the screen. You. On the other hand, the viewing direction R higher than the viewing direction Rb
In the shooting range W 'in b', the enemy character C5 cannot be shot and cannot be displayed on the screen. Therefore, in order to avoid such a case, the height Hb in the viewing direction Rb is set lower than the height Ha in the viewing direction Ra.

Also, as shown in FIG.
When the character 1 is away from the enemy character C2, the enemy character does not exist immediately near the camera V. Therefore, by increasing the height in the line-of-sight direction Ra, a distant range in the virtual space where a plurality of enemy characters exist can be displayed on the screen.

As is clear from the above, the angle θb of the line of sight Rb and the angle θa of the line of sight Ra are the same angle.

FIG. 24 is a diagram showing an example of a screen of the display 2 corresponding to FIG. As shown in FIG. 24, by looking at the virtual space from the viewing direction Rb, the enemy character C2 closest to the self character C1 is displayed side by side on the screen.

As described above, the self-character C1 and the enemy character C2 are displayed side by side on the screen, that is, arranged and displayed on the left and right, so that the player can self-character in the screen depth direction as shown in FIG. Compared to the case where the character C1 and the enemy character C2 are arranged, the self-character C
The distance between 1 and the enemy character C2 or the like can be more easily grasped. As described above, in the fighting game in which the fighting is performed by approaching, as shown in FIG.
It is preferable that the screen is displayed so that the distance between 1 and the enemy character C2 can be grasped.

FIG. 25 is a schematic view of the virtual space viewed from above, and is a diagram for explaining switching between the viewing direction Ra in FIG. 20 and the viewing direction Rb in FIG. In FIG. 25, when the distance between the self-character C1 and the enemy character C2 reaches a predetermined radius R, the camera V moves from the viewpoint coordinates Pa to the viewpoint coordinates Pb over a predetermined time while drawing an arc around the gazing point Qb. . Therefore, until the position of the camera V moves from the viewpoint coordinates Pa to the viewpoint coordinates Pb, the display screen is gradually switched in accordance with the position of the camera V, and smooth screen switching is performed.

At this time, the height at the fixation point coordinates Qb is also smoothly switched from the height Ha to the height Hb over the above-mentioned predetermined time.

FIG. 26 shows the case of FIG. 22, that is,
FIG. 9 is a diagram showing the direction of the camera V when the distance between the self-character C1 and the closest enemy character C2 is within the above-mentioned predetermined radius r, and when there are a plurality of enemy characters within the above-mentioned predetermined radius r. .

In such a case, the angle θc of the line-of-sight direction Rc is set to be larger than the angle θb of the line-of-sight direction Rb. More specifically, the viewpoint coordinates P in the line-of-sight direction Rc
c is set at a position higher than the viewpoint coordinates Pb, and the gazing point coordinates Qc are the same coordinates as the gazing point coordinates Qb. Angle θc
For example, it is 30 degrees.

The reason for making the angle θc larger than the angle θb is as follows. That is, when many characters are densely arranged in a narrow range where a plurality of (for example, three or more) enemy characters C2 exist within the predetermined radius r, the enemy characters or the self character C1 and the enemy character are It may be displayed on the screen overlapping. In such a case, the character on the far side is hidden by the character on the near side, and the player cannot see the movement of the hidden character, which is inconvenient. In particular, when an enemy character hidden in the back fights with the self-character C1, the player may not be able to avoid the opponent's attack and may receive the attack because the movement of the enemy character is invisible.

In order to avoid such inconvenience, when a plurality of characters exist in a narrow range, an image as if looking down at the virtual space is obtained by increasing the angle of the line of sight, so that the characters overlap. Can be prevented.

Therefore, the player can clearly see the movement of the character on the back side, and can quickly respond to an attack from an enemy character on the back side.

FIG. 27 is a flowchart of the third embodiment. In step S11, the distance between the player character C1 and the closest enemy character C2 is determined. If the distance between the characters is larger than the predetermined radius r, the process proceeds to step S13, and the image in the line-of-sight direction Ra described with reference to FIGS. The image to be arranged is displayed.

If the distance between the characters is within the predetermined radius r, the process proceeds to step S12, and the number of enemy characters existing within the predetermined radius r is determined. In step S12, the number of persons is a predetermined number (for example, three persons)
If less, the process proceeds to step S14, and the image in the viewing direction Rb, that is, the self character C1 and the enemy character C
2 and the like are displayed on the screen.

Further, if the number of persons is equal to or more than the predetermined number in step S12, the process proceeds to step S15, and an image in the line-of-sight direction Rc at an angle higher than the line-of-sight direction Rb is displayed.

[0126]

According to the present invention, when characters approach each other in a virtual space in a game, an image that looks down on the virtual space is displayed on the display by raising the viewpoint coordinates in the virtual space. Therefore, on the display screen, the character operated by the player and the enemy character can be displayed without overlapping. This allows the player to clearly see the movement of the enemy character. And, since the player can clearly see the movement of the enemy aircraft, even when the two approach and fight each other, it is possible to quickly respond to the attack from the enemy aircraft, The performance is improved.

Further, by setting an upper limit on the rise of the viewpoint coordinates, it is possible to prevent the viewpoint coordinates from being set immediately above the character, and to impair the three-dimensional sense of distance in the virtual space image displayed on the display. Not to be.

When the character can move in an arbitrary direction in the three-dimensional virtual space, the viewpoint coordinates and the gazing point coordinates are set so that both the enemy aircraft and the own aircraft are displayed during the movement of the character. Therefore, the enemy aircraft does not disappear from the screen, and the player does not lose sight of the enemy aircraft.

Furthermore, in a one-to-many fighting game,
By switching the line-of-sight direction according to the positional relationship between the self-character C1 and a plurality of enemy characters, it is possible to provide a screen in which the positional relationship with the enemy character can be more easily understood.
