FIGS. 3A, 3B, 4A,
5B, 5A and 5B show examples of images generated according to the present embodiment. In FIG. 3A, the player operates his / her character 20 (soldier) by moving the machine gun of FIG. In FIG. 3A, the player has triggered the machine gun and is attacking the enemy character 22. Marker object 23 of enemy character 22

It is also possible for another character, for example, an ally character 30 to take over. The marker object 31 on which the player identification image is mapped also follows the ally character 30, and as a result, the player
You can easily identify it as a friend.

As shown in FIG. 4A, in the present embodiment, the aiming object 40 for setting the aim of the shooting is arranged in the object space. In this case, in the present embodiment, the aiming object is arranged at a position specified by the direction in which the machine gun is directed (the aiming direction of shooting) in FIG. More specifically, assuming that the shot is being shot in the direction of the machine gun even if the player does not trigger the machine gun, the hit check between the line segment specified by the direction of the machine gun and the object is performed. Do. Then, the aiming object 40 is arranged near the hit position specified by the hit check. In FIG. 4A, the hit position is a position on the surface 43 of the object 42, and the aiming object 40 is arranged near the hit position.

On the other hand, in FIG. 4B, the player rotates the machine gun shown in FIG. 1, and the aiming object 40 has moved to the right. Then, the hit position in this case is a position on the surface 45 of the object 44, and the aiming object 40 is arranged at this hit position. Since the object 44 is located at a position farther than the object 42, the aiming object 40 in FIG. 4B appears smaller than that in FIG.

The aiming object 40 is constituted by, for example, one or a plurality of primitive surfaces (polygons, curved surfaces, etc.).

In FIG. 5A, the surface 4 of the object 46
8 is not perpendicular to the line of sight from the viewpoint of the player (not parallel to the screen which is the projection plane). Also in this case, in the present embodiment, the aiming object 40 is arranged in the object space such that the main surface of the aiming object 40 is substantially perpendicular to the line of sight. By doing so, the aiming object 40 can be arranged so as to always face the front as viewed from the player, regardless of the direction of the surface 48 of the object 46.

In FIG. 5B, the aiming object 40
Are arranged near the position of the enemy character 50 (target object). In this state, when the player triggers the machine gun, the shot hits the enemy character 50. In this case, in the present embodiment, the image of the aiming object 40 is changed. That is, when the probability that the shot will hit the target object is high, the color of the image of the aiming object 40 changes from yellow to red, for example. This allows the player to clearly recognize that the trigger now triggers the shot to hit the target object.

As described above, the first feature of the present embodiment resides in that the aiming object 40 for setting the aim of the shooting is arranged in the object space as shown in FIG. That is, in the conventional image generation device,
As shown in FIG. 7A, the aim 300 has been arranged on a two-dimensional layer 302 for displaying scores, rankings, and the like. Then, a screen (projection plane) 30 is formed by a perspective transformation with the image 304 of the two-dimensional layer on which the aim and the like are arranged.
The image 310 as shown in FIG. 7B is generated by superimposing the image 308 projected on No. 6 and the image 310 is displayed to the player. For this reason,
A shift occurs between the position of the aim 300 and the actual hit position 312. The magnitude of the shift varies depending on the depth coordinates of the hit position. For this reason, the player could not accurately grasp the hit position of the shot.

On the other hand, in this embodiment, as shown in FIG. 6, the aiming object 40 is arranged not in the two-dimensional layer but in the object space. Therefore, the player can accurately grasp the hit position of the shot (a position that is considered to be a hit position after a shot) without depending on the depth coordinates of the hit position.

A second feature of the present embodiment is that the aiming object is arranged at a position in the object space specified by the shooting direction. Thereby, the aiming object 40 can be moved in the object space in accordance with the shooting aiming direction (the direction in which the machine gun faces) 52. That is, the aiming object 40 is linked to the shooting direction 52.
Can be moved in the object space. Then, when the aiming object 40 is arranged at a position far from the viewpoint, the aiming object 40 is displayed small by the perspective method, and is enlarged when arranged at a position close to the viewpoint. As a result, the operation of the machine gun and the aiming object 4
The sense of interlocking with the movement of 0 can be increased.

A third feature of the present embodiment is that FIG.
(A) and (B) are that the aiming object 40 is arranged such that the main surface of the aiming object 40 is substantially perpendicular to the line of sight 56 from the viewpoint 54 of the player. In other words, the aiming object 40 is arranged such that the main surface of the aiming object 40 is substantially parallel to the perspective transformation screen 58. By doing this,
The aiming object 40 can be arranged so as to always face the front as viewed from the player, without depending on the direction of the surface 62 of the object 60 near the hit position. By doing so, it is possible to prevent a situation in which the aiming object 40 is deformed and appears due to the direction of the line of sight 56 or the surface 62.

Note that, as shown in FIG.
The aiming object 40 may be arranged so that the surfaces 65, 66, 67, 68, and 69 of the fourth object and the main surface of the aiming object 40 are substantially parallel. In this case, for example, in the case of E1 or E2 in FIG. 9, the aiming object 40 does not face the front as viewed from the player,
A situation occurs in which the aiming object 40 is deformed and appears (for example, the width of the aiming object 40 becomes narrow in E1 and E2). However, according to the method of FIG. 9, the aiming object 40 is
It looks like it is always sticking to 9. For this reason, the unnaturalness that the aiming object 40 appears to float from the surfaces 65 to 69 (FIGS. 8A and 8B)
This method may cause such unnaturalness)
Can be eliminated.

A fourth feature of the present embodiment is that even when the shooting operation of the shot is not performed, the hit check with the object is performed based on the aiming direction of the shooting, and the hit specified by the hit check is performed. The point is to place the aiming object near the position.

For example, in F1, F2, F3, and F4 of FIG. 10, even if the machine gun is triggered (even if a shot shooting operation is performed), the shot does not hit the target object 70. Therefore, normally, F1, F
In the cases of 2, F3 and F4, the player has not triggered the machine gun, and in the case of F5, the player has triggered the machine gun.

However, in the present embodiment, not only in the case of F5 in which the player is triggering, but also in the case of F1, F2, F3, and F4 in which the trigger has not been triggered (the shot shooting operation is not performed). A hit check is performed based on the shooting direction (the direction the machine gun is facing). Then, the aiming object 40 is set near the hit position specified by the hit check.
Is displayed. In this way, the player can operate the machine gun to move the aiming object 40 and, when the aiming object 40 overlaps the target object 70, trigger the machine gun to hit the target object 70 with a shot. become able to. As a result, the player can easily hit the target object 70 with a shot, and the degree of immersion of the player in the game can be increased.

A fifth feature of the present embodiment is that the image of the aiming object is changed according to whether or not a shot by shooting hits the target object.

For example, G1, G2, G3,
In G4, the shot does not hit the target object 70, but in G5 it does. In the case of G5, for example, the color of the aiming object 40 is changed,
The aiming object 40 blinks. Thus, the player can easily recognize that the shot hits the target object 70 when shooting is performed now. In particular, as described in FIG.
This technique of changing the image is effective in a technique of always performing a hit check regardless of whether or not the machine gun is triggered and displaying the aiming object 40 at the hit position. This is because the player can more clearly recognize that the aiming object 40 has overlapped the target object 70.

Various methods can be considered as a method of changing the image. For example, in FIG. 11B, if the shot does not hit the target object 70 as shown by H1, H2, H3, and H4, the display of the aiming object 40 is turned off. On the other hand, when the shot hits the target object 70 as in H5,
The display of the aiming object 40 is turned on.

Next, a detailed processing example of this embodiment will be described.
This will be described with reference to the flowchart of FIG.

First, the position of the moving object (own character) is calculated (step S1). In the present embodiment, the position of the moving object is calculated for each frame in real time based on operation data and a program from the player.

Next, the direction of the machine gun is calculated (step S2). This is realized, for example, by electrically detecting the rotation angle of the machine gun.

Next, a line segment is specified based on the position of the moving body (or the viewpoint position) obtained in step S1 and the direction of the machine gun obtained in step S2 (the aiming direction of shooting). A hit check with the object is performed (step S3).

For example, in FIG. 13, a line segment 76 is specified based on the position 72 of the moving body and the shooting direction 74. In this case, the map in the object space is shown in FIG.
As shown in FIG. 3, it is divided into a plurality of meshes. Then, a mesh where the line segment 76 intersects is searched from these meshes. In FIG. 13, a mesh with diagonal lines is selected. Then, an object to which at least a part belongs to the mesh is searched. In FIG. 13, objects 78, 80, and 82 are selected and object 8
4, 86, 88, 90 are not selected. And line segment 7
The intersections between 6 and the objects 78, 80, 82 are obtained as hit positions 91, 92, 93, 94, 95.

Next, a hit position closest to the moving body is selected (step S4). In FIG. 13, hit position 95 is selected.

Next, the direction of the main surface of the aiming object is calculated (step S5). For example, as described with reference to FIGS. 8A and 8B, the direction substantially perpendicular to the line of sight is the direction of the main surface of the aiming object.

Next, it is determined whether or not the shot hits the target object (step S6). When it is determined that the shot hits the target object, the image of the aiming object is changed as described with reference to FIGS. 11A and 11B (step S7). For example, in FIG. 13, the image of the aiming object is not changed because the target object 80 is not hit.

Next, the aiming object is arranged at the hit position (step S8). For example, in FIG. 13, the aiming object is arranged at the hit position 95. At this time, the aiming object is arranged so that the main surface faces in the direction obtained in step S5.
