Description

  The present invention relates to an image processing technique, and more particularly to an image processing technique suitable for controlling a special behavior of a character and a viewpoint in a game program.

  3D image processing technology is used in game devices. That is, the three-dimensional shape of an object such as a player character operated by a player, an enemy character that becomes an enemy of the player character, its position and its movement are defined in a three-dimensional coordinate that is an image data space. The video is viewed from the camera, and a virtual reality world such as a battle between a player character and an enemy character is displayed on the screen. The 3D image processing technology can provide a variety of images to the user by allowing the designer to design not only the movement of the character but also the movement of the viewpoint in various ways.

The movement of the character is based on the player's operation, but when the character is moved in a special behavior (for example, a special move), the computer automatically controls the character based on the program. Related techniques are described in, for example, WO1997 / 046295 and JP2003-067780.
WO1997 / 046295 JP2003-067780

  The special behavior of the character occurs, for example, when the character exists at a certain position in the three-dimensional virtual space and a button for feeding out an input from the user, such as punching or kicking an enemy character, is pressed. However, in the past, special behavior with a large coordinate movement of the character has been performed in places free from obstacles, such as outdoors. However, if it is generated in a narrow place such as indoors or in a passage, there is a problem that it enters the wall, and special behavior cannot be implemented.

  In addition, when the viewpoint is moved in accordance with the special behavior of the character, there is a problem in that the viewpoint cannot be displayed accurately because the viewpoint penetrates into a structure such as a wall or the ground in the data space.

  Accordingly, an object of the present invention is to provide an image processing technique that prevents special behavior of a plurality of characters from becoming unnatural even if the plurality of characters take special behavior. Furthermore, an object of the present invention is to provide an image processing technique in which viewpoint control can accurately display the behavior of a plurality of characters. It is another object of the present invention to provide an image processing technique capable of controlling the movement of characters and viewpoints so that special behaviors of a plurality of characters can be accurately displayed.

  In order to achieve the above object, the first image processing according to the present invention includes means for calculating a position of the object in the space of the image data, means for setting a region for causing a special behavior in a plurality of objects, and These two determinations are affirmed: means for determining whether or not the object is included in the area; means for determining whether or not the object has a predetermined command via the input device; In this case, there is provided means for forcibly moving the object to a position where the special behavior is possible, and means for moving the viewpoint together with the object.

  According to the present invention, means for determining whether or not the object is included in the area, means for determining whether or not the object has been instructed to perform the special behavior, and these two determinations Means for forcibly moving the object to a position where the special behavior is possible when the object is affirmed. It is possible to ensure that the character can move in a special behavior pattern in the appropriate area.

  Furthermore, the second image processing according to the present invention includes means for calculating the position of the object in the space of the image data, means for generating a special behavior in a plurality of objects, and moving the viewpoint together with the special behavior of the object. Means for calculating the position of the viewpoint, means for determining whether the path of the special behavior collides with another object, and determining that the path of the special behavior collides with the other object. And a means for moving the path of the special behavior to a range that does not collide with the object.

  According to the present invention, the operation target object is corrected to a position that does not interfere with other objects, so that the image of the operation target object is accurately displayed from the viewpoint.

  As described above, the present invention can provide an image processing technique that prevents a special behavior of an object from becoming unnatural even if a plurality of objects to be operated have a special behavior.

  Furthermore, the present invention can provide an image processing technique in which the viewpoint control can accurately display the behavior of a plurality of objects. Furthermore, the present invention can provide an image processing technique capable of controlling the movement of an object or a viewpoint so that special behaviors of a plurality of objects can be accurately displayed.

  Next, an embodiment of the present invention will be described. In this embodiment, the image processing of the present invention is applied to a game device. The game is realized by placing a player character and an enemy character in a three-dimensional coordinate space, moving these characters based on user operations, and fighting between the characters. Furthermore, the player character performs a special behavior when a predetermined condition is satisfied.

  FIGS. 1 (1) to (3) are monitor screen outputs corresponding to special behaviors. The figure shows a process in which the person 2 operated by the user presses the person 3 as an enemy against the wall 1 and defeats the enemy. This series of processes is the special behavior of the player character 2. The “person operated by the user” is an object to be operated, that is, a player character. The “enemy person” is the enemy character 3 operated by the image processing apparatus or operated by another player.

  In the special behavior, when the player character and the enemy character move near the wall and the user gives an attack instruction to the player character via the operation device, the image processing apparatus automatically reproduces the special behavior.

  FIG. 2 is an example of a hardware block of a processing board of the image processing apparatus, and can be applied to a game device for business use or home use, a personal computer, a portable computer, a mobile phone, and the like.

  The processing board is operated by a program and controls the entire apparatus, a system memory 22 for storing a program and data used by the CPU, and a program data for storing game programs and data such as output images and sounds. A storage medium 24 such as a ROM, a boot ROM 26 for storing a program for initializing each block when the apparatus is started, a bus arbiter 28 for controlling a bus for exchanging a program and data between the blocks, The geometry processor 30 that calculates the position coordinates and orientation of the (polygon) object (display body) to be displayed on the display in the three-dimensional virtual space or two-dimensional coordinates, and the orientation and position coordinates of the object calculated by the geometry processor Based on this, generate an image to output to the display ( A rendering processor 32 connected thereto, a graphic memory 34 for storing data and commands for generating images, an audio processor 36 for generating sound to be output to a speaker, and a sound processor connected to the rendering processor 32 for generating sound. And an audio memory 36A for storing data and commands for the purpose. Reference numeral 38 denotes a communication I / F, and reference numeral 40 denotes a peripheral interface.

  The system memory, graphic memory, and sound memory may be used in common for each function by connecting one memory to the bus arbiter, and each functional block only needs to exist in the image processing apparatus as a function. The functional blocks may be integrated, or each component inside the functional block may be separated as another block.

  The ROM for program data is an IC memory that can read data electrically, such as a mask chrome or flash ROM, a device that can read data optically such as a CD-ROM, a DVD-ROM, and an optical disk or a magnetic disk. Also good. The bus arbiter incorporates an interface for inputting and outputting data from the outside, and a peripheral as a peripheral device is connected thereto.

  Peripherals include switches for key operations such as a mouse (pointing device), a keyboard, and a game controller.

  In FIG. 3, the process (behavior pattern) of the special behavior of the player character is indicated by reference numeral 300. Reference numeral 300A is a start point of special behavior, reference numeral 300B-D is an intermediate point, and reference numeral 300E is an end point. The player character moves so as to pass through each point, and in the process, in order to defeat the enemy character, a punch, a kick or the like is sent out.

  Reference numeral 302 indicates a process of enemy character behavior. Reference numeral 302A is a behavior start point, reference numerals 302B-D are intermediate points, and reference numeral 302E is a final point. The player character and the enemy character operate in relation to each other in the positional relationship shown in FIG. 3, that is, close to each other. The positional relationship and behavior of both characters are stored in the storage medium 24 as game data. The CPU 20 refers to this game data, links two characters to each other, and operates according to the behavior shown in FIG. At the end points of the behavior patterns of both characters, for example, as described above, the behavior such as the player character hitting the enemy character against the wall is reproduced on the display monitor.

  The behavior patterns shown in FIG. 3 of the player character and the enemy character, that is, the coordinates of the start point, the intermediate point, and the end point are defined in the local coordinate system. On the other hand, the field of the entire fighting game is defined in the global coordinate system. By defining the origin of local coordinates as a predetermined point on global coordinates, the special behavior pattern of the character can be mapped to the global coordinate system. When mapping local coordinates to global coordinates, the direction in which the character behavior pattern is reproduced can be controlled by adjusting the direction of the local coordinate system (for example, the Z-axis direction).

  The special behavior pattern of the player character is not started when the user simply operates the player character. This depends on both the position of the player character in the global coordinate system and whether or not the user has given a command such as punching to the player character. When these requirements are affirmed, the CPU 20 controls the character based on the data stored in the storage medium 24 so that the character operates according to the special behavior.

  FIG. 4 is a perspective view showing a state where the player character 400 and the enemy character 402 are fighting in the vicinity of the wall. For convenience, when at least one of the player character and the enemy character enters the range 404 surrounded by the cube, and the special input from the user is input to the CPU 20 via the peripheral, the CPU allows the special behavior to occur. . Since the special behavior is that the player character strikes the enemy character against the wall, the determination area 404 is provided adjacent to the wall.

  Next, a flowchart for the CPU to move the character as shown in FIG. 5 will be described. This flowchart is stored in the storage medium 24 as a program.

  First, the CPU reads the coordinates of the player character and the enemy character, and determines whether these coordinates are within the cubic determination area (4000). If this determination is negative, the player character and the enemy character are operated in a normal behavior according to the user input (4004). The normal behavior is, for example, jump, kick, punch, etc. that usually appear in a fighting game.

  As shown in (1) of FIG. 4, when the player character pursues the enemy character toward the wall and enters the determination area 404, the determination in step 4002 is affirmed. Next, the CPU determines whether or not there has been an attack input (specific button operation) from the user. If the determination is affirmative, the CPU calculates the direction in which the player character approaches the wall, and along this direction, the special behavior is calculated. The direction of the local coordinate system that is the basis of the character is determined, and the special behavior pattern of the character in the local coordinate system is mapped in this direction to the global coordinate system (4008). If step 4006 is negative, the process proceeds to step 4004.

  The CPU calculates the positions of the player character and the enemy character, and the starting point of the behavior pattern of the character (FIG. 3) is one action of the player character, for example, the player character hits the enemy character against the wall with one punch. If it does not coincide with the position where it can be made (405 in FIG. 4), that is, the position where the special behavior is successful, the player character and the enemy character are forcibly moved to 405 in FIG. (4010). This process is shown in (2) of FIG. In (2), the player character and the enemy character are forcibly moved to the target position 405 in a direction perpendicular to the wall as indicated by an arrow 401.

  Reference numeral 410 in (1) is a viewpoint position, and an arrow 412 is a viewing direction. The viewpoint of (1) is at a position where the character is normally moving, and (2) shows the position and viewing direction of the viewpoint when the special action of the character is started. The viewpoint is set at a position and a direction where the character during the special action can be accurately presented to the user. These viewpoints move together with the character. Next, the CPU controls the player character and the enemy character with the special behavior, and ends the example process.

  Next, the viewpoint behavior pattern will be described. As shown in FIG. 6, the behavior of the viewpoint has a plurality of patterns. There are three viewpoint behavior patterns: C1, C2, and C3. The behavior pattern of the viewpoint that can most accurately express the special behavior pattern is determined in advance in the program. In FIG. 6, 60 is a wall in a three-dimensional coordinate space (global coordinate system), and 62 is a road between the non-road sections 65 and 65A. Each viewpoint pattern operates through the illustrated viewpoint, intermediate point, and end point.

  When a special behavior occurs in a character, if the viewpoint moves with the character, the viewpoint moves into another object. FIG. 6 shows a state in which the end point of C1, which is the viewpoint with the highest program priority, is embedded in the wall. At this time, the CPU selects another viewpoint pattern and displays the special behavior of the character as an image.

  FIG. 7 is a viewpoint control flow, which is executed by the CPU based on a program stored in a storage medium. At the stage when the special behavior command is generated, the CPU performs a collision determination between the coordinates of each point through which the viewpoint behavior pattern passes and other objects (walls) for a plurality of viewpoint behavior patterns (700). Here, the collision determination is a determination as to whether the coordinates of the camera overlap the object by comparing the coordinates of the camera with the coordinates of another object. A collision determination is affirmed for camera pans that overlap at least one relay point, and a collision determination is denied for camera patterns that do not overlap at all intermediate points.

  If there are two or more camera patterns for which the collision determination is denied, the priority of the camera pattern is determined (702), and the position of the viewpoint and the movement path are determined based on the camera pattern with the higher priority (704). ). If there is no camera pattern for which the collision determination is denied, the degree of collision determination is compared with each camera pattern, and the viewpoint movement control is performed based on the camera pattern with a small degree of collision determination (706). For example, it is determined that the smaller the number of intermediate points at which the collision determination is affirmed, the smaller the degree of collision determination. In the viewpoint movement control at this time, when each point constituting the camera pattern is located in the wall, the position of the entire camera pattern is moved (corrected) so as to be the coordinates of the surface of the wall (708).

  Next, it is a perspective view which shows other embodiment of the special behavior of a character. The difference between this embodiment and the embodiment described above is that the special behavior of the character is reproduced by an input instruction from the user regardless of the determination area 404 in FIG. When a command for generating a special behavior is generated, the CPU calculates that this command is a special behavior command, and starts position control of the character movement pattern. The contents of this control are shown in (1)-(3) of FIG.

  The CPU performs a collision determination between the intermediate point of the character's special behavior and another object, and if there is no collision, reproduces the character's special behavior pattern. This state corresponds to (1) in FIG. For convenience, a cubic region indicated by 800 (outer periphery of the behavior pattern) does not enter the wall.

  In the case where at least one point in the moving process of the character gets into the wall (FIG. 8 (1), FIG. 9), as shown by reference numeral 802 in FIG. (404) is moved a predetermined distance away from the wall in the normal direction. In FIG. 9, the behavior pattern of the character shown in FIG. 3 is displayed superimposed on another object placed in the three-dimensional coordinate space. The end point 300E of the player character and the end point 302E of the enemy character have entered the wall. As the movement distance, a value is selected such that each point on the character's movement path has coordinates that do not fall within the wall. Next, the special behavior of the character is reproduced based on the special behavior pattern of the character.

  As another mode for eliminating the overlap with the object, as shown in FIG. 10, the behavior pattern of the player character and the behavior pattern of the enemy character are integrally rotated (θ) with a predetermined point as a reference. 300 ′ is a set of points in the behavior pattern of the player character after rotation, and 300 is the one before rotation. The same applies to the enemy character 302.

  The rotational movement is performed every predetermined angle (for example, clockwise or counterclockwise every 45 °). The CPU performs a collision determination at each rotation. When the collision disappears, the behavior pattern after correction of the character is determined. When there is a collision at all angles, the character is moved (minimum) so as to be separated from the wall along the normal direction of the wall so that each point of the behavior pattern does not collide with the wall. At this time, the behavior pattern of the character is rotated according to an angle that requires the least amount of movement.

  FIG. 11 is a modification of FIG. 4 and shows a case where the player presses the attack button on the control pad in a state where the player character and the enemy character are in the determination area and close to the wall. In this case, as shown in FIGS. 11 (1) to (2), the CPU moves the positions of both characters from the vicinity of the wall along the vertical direction from the wall to the forced movement destination so as to move away from the wall. . As a result, the CPU performs automatic reproduction accurately and accurately, independently of the user's operation, such that the player character strikes the enemy character against the wall. Characters cannot realize special behavior at positions approaching the wall.

  According to the above embodiment, even if the operation target object has a special behavior, the special behavior of the object is not unnatural. In addition, the viewpoint control can now accurately display object behavior.

  The embodiment described above is an example of the present invention, and the present invention is not limited to this embodiment and can be modified as appropriate. For example, the image processing apparatus of the above-described embodiment can be applied to any of a home game device, an arcade game device, a personal computer, and a mobile phone.
