Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the prior art, the AI role in many games has only realized the function of automatic following, nevertheless follows the authenticity of removing to the AI role, and the smoothness, the rationality requirement is lower, then can often appear following several kinds of problems:
AI role is when following the removal, and the change of unable perception terrain environment and barrier leads to AI role can be lifelike following the in-process and collide the barrier and avoid again to give the very silly sensation of AI role for the player.
And 2, the collision between the player character and other NPC characters is ignored when the AI character moves along with the player character, so that various interpenetration can be generated between the AI character and the player character or other NPC characters in the following process, and the player can feel rough by the AI character.
And 3, the AI character cannot sense the movement of the player character or other teammate characters in the following movement process, so that the AI character often blocks the movement of the player character or other teammate characters in the following process and cannot form an aesthetic and natural formation type co-movement impression, thereby providing a hard feeling for the AI character.
The inability of the AI character to predict the direction of the player character's action during the following movement results in the AI character only being able to move and stop at all times during the following process, thereby giving the player a mechanical feel to the AI character.
For example, The reality and rationality Of single person following are realized in The AI role following scheme Of The Last Of Us, but The customization degree Of The AI role following scheme is extremely high, The universality is poor, and The following movement Of multiple AI roles cannot be expanded. As in the AI character following scheme of final fantasy XV, reality and fluency of multi-user following are realized, but the scheme has random control over the movement logic of the AI character, and cannot enable the whole AI character to form an attractive and natural formation to move together, and the movement track of a player is not predicted.
In order to solve the problems that the AI character is not really true enough when following the player, the following movement is mechanical, hard and silly, and the like, in the embodiment of the invention, a plurality of following point positions corresponding to the positions of the virtual character are obtained; determining a target point position corresponding to at least one AI role from the plurality of following point positions, and distributing the target point position to the at least one AI role; respectively determining motion influence factor information corresponding to at least one AI role; and controlling at least one AI role to move to the target point according to the motion influence factor information. A plurality of following point positions corresponding to the positions of the virtual roles are generated through pre-design, and the following point positions are allocated to different AI roles, so that the common degree of the AI roles is high, the AI roles can be expanded to a plurality of AI roles from a single AI role, the AI roles can move together in an attractive and reasonable formation, and the station positions of the AI roles can be adjusted according to the positions of teammates and players at all times. Moreover, by determining the motion influence factor information corresponding to at least one AI character, the AI character can intelligently avoid the player character, the teammate character or the obstacles in the environment when moving, for example, the AI character can sense the change of the surrounding terrain environment and avoid in advance before the AI character collides with the obstacles, or the AI character can not move to neglect the collision with the player character and the teammate character and not to interleave with the player character and the teammate character, or the AI character can predict the moving direction of the player and timely make corresponding reactions to avoid obstructing the movement of the player, or when the player character repeatedly starts and stops, the AI character can recognize the behaviors according to a certain algorithm and make more reasonable reactions to avoid the stop and go caused by repeated brain-free following.
The AI character control method in a game in one embodiment of the present invention may be executed in a local terminal device or a server. When the AI character control method in the game is run on the server, the AI character control method in the game may be implemented and executed based on a cloud interactive system, wherein the cloud interactive system includes the server and the client device.
In an optional embodiment, various cloud applications may be run under the cloud interaction system, for example: and (5) cloud games. Taking a cloud game as an example, a cloud game refers to a game mode based on cloud computing. In the running mode of the cloud game, a running main body of a game program and a game picture presenting main body are separated, the storage and the running of an AI role control method in the game are finished on a cloud game server, and a client device is used for receiving and sending data and presenting a game picture, for example, the client device can be a display device which is close to a user side and has a data transmission function, such as a first terminal device, a television, a computer, a palm computer and the like; but the cloud game server of the cloud is used for carrying out the AI role control method in the game. When a game is played, a player operates the client device to send an operation instruction to the cloud game server, the cloud game server runs the game according to the operation instruction, data such as game pictures and the like are encoded and compressed, the data are returned to the client device through a network, and finally the data are decoded through the client device and the game pictures are output.
In an optional implementation manner, taking a game as an example, the local terminal device stores a game program and is used for presenting a game screen. The local terminal device is used for interacting with the player through a graphical user interface, namely, a game program is downloaded and installed and operated through an electronic device conventionally. The manner in which the local terminal device provides the graphical user interface to the player may include a variety of ways, for example, it may be rendered for display on a display screen of the terminal or provided to the player through holographic projection. For example, the local terminal device may include a display screen for presenting a graphical user interface including a game screen and a processor for running the game, generating the graphical user interface, and controlling display of the graphical user interface on the display screen.
Referring to fig. 1, a flowchart illustrating steps of an embodiment of an AI character control method in a game according to an embodiment of the present invention is provided, where a graphical user interface is provided through a terminal device. The terminal device may be the aforementioned local terminal device, and may also be a client device in the cloud game system. The content displayed by the graphical user interface includes at least a part of a game scene, and the game scene includes at least one virtual character and at least one AI character corresponding to the virtual character, and the method specifically includes the following steps:
step 101, acquiring a plurality of following point positions corresponding to the positions of the virtual roles;
the game of the embodiment of the present invention may be executed in a terminal device, and the terminal device may be a portable mobile terminal, such as a smart phone, a wearable device, a Personal Digital Assistant (PDA), a Point of Sales (POS), a vehicle-mounted computer, and the like, or may be an electronic device such as a notebook computer, a tablet computer, and an IPAD. The terminal device may be provided with a touch screen, and for convenience in operation, the touch screen may be used instead of a mouse or a keyboard. The touch screen is composed of a touch detection part and a touch screen controller, wherein the touch detection part is arranged in front of the display screen and used for detecting the touch position of a user and then transmitting related information to the touch screen controller. The touch screen controller is mainly used for receiving touch information from the touch point detection device, converting the touch information into touch point coordinates and transmitting the touch point coordinates to a Central Processing Unit (CPU); it can receive and execute the command from CPU. When a finger, stylus or other operating medium applies pressure (or force) to a touch screen mounted on the front end of the display, the touched position is detected by the touch screen controller and sent to the CPU through an interface (e.g., RS-232 serial port, USB, etc.).
The method comprises the steps of running a game application on the terminal device and rendering a graphical user interface on a touch screen of the terminal device, wherein the content displayed on the graphical user interface comprises at least part of a game scene, and the game scene can comprise at least one virtual character which can be a game virtual unit controlled by a player through the terminal device. In addition, the game scene may further include at least one AI character corresponding to the virtual character, where the AI character is a character accompanying around the virtual character controlled by the player, and may assist the virtual character controlled by the player to perform combat or interaction, and the like.
The AI character should be in a reasonable position relative to the virtual character being manipulated by the player during the course of following. In the embodiment of the present invention, following points of some AI characters can be generated by pre-design, as shown in fig. 2, a series of points can be obtained by defining a distance and an angle behind a player character. Because the formation often has a plurality of AI characters in the removal process, so need a plurality of following points, and the spatial position behind the player character is limited, in order to avoid the station position of a plurality of AI characters too concentrated, can design following point position and the distance between the player character has a variety, according to following the distance length between point position and the player character, can also divide into different levels following the point position, as in fig. 2, contain the following point position of two levels, wherein, first floor point position has 3, second floor point position has 2.
In an actual game scene, some expected positions cannot be reached due to the influence of obstacles, so that the environment between the virtual character and the following point location needs to be sensed, and the obstacle is prevented from existing between the positions where the following point location is located or existing between the virtual character and the following point location. In a specific implementation, sensing the environment may be performed by emitting a detection ray, which is not limited in this embodiment of the present invention.
In a preferred embodiment of the present invention, after the step 101, the method may further include the steps of:
sequentially determining a currently operated point location from the plurality of following point locations; emitting a detection ray to the currently operated point location according to the position of the virtual role; and when the detection ray collides with a virtual object in the game scene, removing the currently operated point location from the plurality of following point locations.
Specifically, the currently operated point location is determined from the plurality of following point locations in sequence, a detection ray is emitted to the currently operated point location according to the position of the virtual character, and when the detection ray collides with a virtual object in a game scene, the currently operated point location can be removed from the plurality of following point locations; and when the detection ray does not collide with the virtual object in the game scene, returning to the step of determining the currently operated point location from the plurality of following point locations, determining the next following point location as the currently operated point location, and continuing to execute the step of transmitting the detection ray to the currently operated point location according to the position of the virtual character until all the following point locations are traversed.
As an example, as shown in fig. 3, for the following point locations shown in fig. 2, since an obstacle exists between the virtual character and the following point locations, the obstacle blocks the two following point locations, namely, the first-layer point location and the second-layer point location on the right side, the two following point locations may be eliminated, so as to avoid assigning the two following point locations to the AI character.
In addition, after a plurality of following points corresponding to the positions of the virtual characters are acquired, weights may be set for the following points, for example, "following point closest to the player takes precedence", "following point behind the player takes precedence", and the like, points equal to the AI number are selected by the weights, and are assigned to the AI characters through subsequent steps.
Step 102, determining target point positions corresponding to the at least one AI role from the plurality of following point positions, and allocating the target point positions to the at least one AI role;
specifically, the target of allocating the following point location may be that each AI character has a small possible moving distance, and the moving distance of each AI character is preferably uniform, so that the visual array adjustment amplitude is small. In a specific implementation, a scheme of assigning following point locations to all AI roles may be given by way of enumeration, a sum of distances between all AI roles and their following point locations in each scheme is calculated, and then a scheme with the smallest sum of distances is selected as a final scheme, so as to determine target point locations corresponding to at least one AI role respectively, and assign the target point locations to at least one AI role.
103, respectively determining motion influence factor information corresponding to the at least one AI role;
the motion influencing factor information may be some information capable of influencing the motion state of the AI character, including an obstacle between the AI character and the target point, a distance between the AI character and the virtual character, a terrain environment and a moving direction in which the virtual character is located, and the like.
In a specific implementation, for each AI character, the corresponding motion influencing factor information may be one or more, for example, an obstacle may exist between the AI character and the target site, and meanwhile, the AI character is far away from the virtual character, in this case, a routing path needs to be re-planned for the AI character, and the AI character is controlled to move at an accelerated speed to quickly catch up with the virtual character.
And 104, controlling the at least one AI role to move to the target point location according to the motion influence factor information.
In the embodiment of the invention, after the movement influence factor information corresponding to each AI character is determined, at least one AI character can be controlled to move to the target point according to the movement influence factor information, so that the AI character can intelligently avoid obstacles and the like in a player character, a teammate character or the environment when moving.
In a preferred embodiment of the present invention, the motion influencing factor information includes any one of:
an obstacle between the at least one AI character and the target site; a distance between the at least one AI character and the virtual character; the terrain environment and the direction of movement of the virtual character.
In a specific implementation, whether an obstacle exists between the AI character and the target point may be detected through a ray detection method, and when the obstacle exists, the AI character needs to avoid the obstacle when moving to the target point. And calculating the distance between the AI character and the virtual character through a distance formula between the two points, controlling the moving speed of the AI character according to the distance between the two points, increasing the moving speed of the AI character when the distance between the two points is longer, and reducing the moving speed of the AI character when the distance between the two points is closer. In addition, the movement of the AI character may also be affected by the terrain environment in which the virtual character is located, and when the environment in which the virtual character is located is narrow, in order to avoid the AI character blocking the movement of the virtual character, the AI character needs to be controlled according to the terrain environment and the movement direction in which the virtual character is located.
It should be noted that the motion-affecting factor information may also be set as some other information as needed, and the embodiment of the present invention is not limited to this.
In a preferred embodiment of the present invention, when the motion-affecting factor information is an obstacle between the at least one AI character and the target point location, the step 104 includes:
controlling the at least one AI character to move linearly to the target point location when no obstacle exists between the at least one AI character and the target point location; when an obstacle exists between the at least one AI character and the target point location, a path finding path is determined through a path finding interface of a game engine, and the at least one AI character is controlled to move to the target point location according to the path finding path.
In the embodiment of the invention, when no barrier exists between the AI role and the target point, the AI role can be directly controlled to linearly move to the target point; when an obstacle exists between the AI role and the target point, the AI role needs to avoid the obstacle so as to avoid the situation of crossing the module, a path-finding path can be determined through a path-finding interface of the game engine, and the AI role is controlled to move to the target point according to the path-finding path.
Specifically, after a target point corresponding to an AI character is set, each AI character needs to move to the target point, which relates to the problem of moving a path, and in most cases, the AI character is closer to the target point, so that a mode of emitting a ray from the current position of the AI character to the target point is tried to judge whether the AI character can move to the target point in a straight line, and if an obstacle is encountered, a game engine routing interface is called to obtain the path.
In a preferred embodiment of the present invention, the controlling the at least one AI character to move straight to the target point location when there is no obstacle between the at least one AI character and the target point location includes:
and emitting a detection ray to the target point according to the current position of the at least one AI character, and controlling the at least one AI character to move linearly to the target point when the detection ray does not collide with the virtual object in the game scene.
Specifically, for each AI character, a detection ray may be emitted to the target point according to the current position of the AI character, and when the detection ray does not collide with a virtual object in the game scene, it indicates that there is no obstacle in the obstacle between the AI character and the target point, and at this time, the AI character may be directly controlled to move linearly to the target point.
In a preferred embodiment of the present invention, when the motion-affecting factor information is a distance between the at least one AI character and the virtual character, the step 104 includes:
determining the current movement speed of the at least one AI role according to the distance and the original movement speed of the at least one AI role; and controlling at least one AI role to move to the target point position according to the current moving speed.
Because the AI character inevitably encounters an obstacle during the movement process, the movement route is likely to be longer than the movement path of the player character, so that the movement speed of the AI character needs to be increased at an appropriate time to ensure that the AI character can keep up with the virtual character controlled by the player, otherwise, the distance between the AI character and the virtual character is increased; meanwhile, when the AI role approaches to the following point position, the moving speed needs to be reduced to keep the moving state, so that the situations of stop and go are avoided. In the embodiment of the present invention, the current movement speed of the AI character may be determined according to the distance between the virtual character and the AI character and the original movement speed of the AI character, and the character may be controlled to move to the target point location according to the current movement speed.
Specifically, the rate (speed _ rate) can be calculated by the following formula:
Figure BDA0003283029790000131
wherein r is1Is a first preset threshold for limiting the movement of the virtual character when the distance between the virtual character and the AI character is close, r2And a second preset threshold, which is used for limiting the movement when the virtual character is far away from the AI character, wherein S is a preset distance length, and distance is the distance between the virtual character and the AI character. As an example, r1＝2，r27, s 15. After the velocity is calculated, a current moving speed may be calculated according to the velocity and the original moving speed, wherein the current moving speed is equal to a product of the original moving speed and the velocity.
In the embodiment of the present invention, when the distance between the at least one AI character and the virtual character is greater than a first preset threshold, the current moving speed is greater than the original moving speed; when the distance between the at least one AI character and the virtual character is less than a second preset threshold, the current moving speed is less than the original moving speed.
The first preset threshold may be a preset maximum distance threshold, and when the distance between the AI character and the virtual character is greater than the first preset threshold, it indicates that the distance between the AI character and the virtual character is relatively long, and at this time, the moving speed of the AI character needs to be increased, so that the AI character can catch up with the virtual character as soon as possible. The second preset threshold may be a preset minimum distance threshold, and when the distance between the AI character and the virtual character is smaller than the second preset threshold, it indicates that the distance between the AI character and the virtual character is short, and at this time, the moving speed of the AI character needs to be reduced to prevent the AI character from moving too close to the virtual character to block the movement of the virtual character. In addition, when the distance between the AI character and the virtual character is between the first preset threshold and the second preset threshold, the AI character can be controlled to move to the target point at a constant speed according to the original moving speed.
In a preferred embodiment of the present invention, when the motion influencing factor information is the terrain environment and the moving direction of the virtual character, the step 104 includes:
if the terrain environment where the virtual character is located is a narrow environment, determining a position which is a preset distance away from the front of the virtual character to be a target position according to the moving direction of the virtual character; controlling the at least one AI character to move to the target location.
In the embodiment of the present invention, if the terrain environment in which the virtual character is located is a narrow environment, the position away from the front of the virtual character by a preset distance is determined as the target position according to the moving direction of the virtual character, and the AI character is controlled to move to the target position.
Specifically, in order to prevent the interpenetration between characters, physical capsules are added on both the player character and the AI character, so that the virtual character and the AI character controlled by the player can be blocked mutually. To improve the game experience, the AI character needs to dodge the movement of the player character. In open areas, the AI role can successfully avoid the virtual role only by adding a certain offset according to the moving direction of the virtual role. However, in narrow terrain, the AI character does not have as much space available for avoidance. For example, the player character can not move continuously in a formation mode by leading the AI characters to pass through a single-rail bridge, and the method that the AI characters temporarily do not keep the formation but seek a path to a certain distant position in the moving direction of the virtual character is adopted, so that the AI characters and the virtual character move in the same direction, and the virtual character is not blocked.
In the implementation, the environment where the virtual character is located needs to be detected in real time, and whether the terrain environment where the virtual character is located is a narrow environment is detected by presetting a narrow zone detection mode. As an example, the detection rays are emitted to the periphery of the virtual character by emitting the detection rays, rays shorter than a certain distance are barrier rays, rays longer than the certain distance are non-barrier rays, a ratio value of the barrier rays to the total number of rays is counted, and if the ratio value is higher than a certain preset threshold (a preset value, for example, 0.8), it is indicated that the virtual character is in a narrow zone, that is, whether the terrain environment where the virtual character is located is a narrow environment.
In a preferred embodiment of the present invention, the method may further comprise the steps of:
when the position of the virtual role changes, controlling the at least one AI role to keep the current motion state to move within a preset time; and after the preset time, re-determining a target point location according to the position of the virtual character after the change, and controlling the at least one AI character to move to the target point location according to the motion influence factor information.
In the embodiment of the present invention, the preset time may be a preset time length, which is used to control an AI character to delay response, and when the position of the virtual character changes, the AI character is controlled to keep moving in a current motion state within the preset time; and after the preset time, re-determining the target point location according to the position of the virtual character after the change, and controlling at least one AI character to move to the target point location according to the motion influence factor information.
Specifically, if the behavior of the AI character is the same as that of the virtual character controlled by the player, that is, the virtual character moves one step, the AI character moves one step, the virtual character stops, and the AI character stops instantaneously, and meanwhile, the AI character and the virtual character move in the same trend, the behavior is similar to that of "being and even, the look and feel are affected, and the nature is not sufficient. Therefore, a delay response and inertia following mechanism is adopted, namely, after the position of the virtual character is changed, the AI character system does not immediately refresh the following point position, but has a certain time delay; meanwhile, due to delayed response, the AI character sometimes has the situation that the trackable point positions do not exist, and the AI character continues to move in the current motion state for a certain time. The mechanism can effectively relieve the phenomenon that the AI role is both a and b, and the expression is more natural.
In a preferred embodiment of the present invention, before the step 104, the method further includes:
adding a collision volume to the at least one AI character.
In the embodiment of the invention, the collision body can be added to the AI role, so that the AI role can intelligently avoid the obstacles in the environment in the moving process.
