[0032] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced without the specific details. In other instances, well-known methods have not been described in detail in order not to unnecessarily obscure aspects of the present application.

[0033] It should be noted that the terms "first", "second", "third", and the like in the description and in the claims of the present application are used for distinguishing between similar objects and not necessarily for describing a sequential or chronological order. The use of such terms in the description is therefore not to be construed as implying a specific order or sequence. Also, the terms "comprises", "comprising", "has", "having", "includes", "including", and the like, are to be construed open- ended, i.e., to mean including but not limited to, to indicate the presence of what follows recited members, steps or elements "comprising", "comprising", "has", "having", "includes" and "including" and the like, are to be construed as specifying the presence of stated members, steps or elements, but not to preclude the presence or addition of one or more other members, steps or elements, or groups thereof. Only the transitional phrases "consisting of and "consisting essentially of are to be construed as being closed or limited terms as defined by statute.

[0034] It should be understood that, in the embodiments of the present application, "at least one" means one or more, and "multiple" means two or more than two. "And / or" is only a description of the relationship between the associated objects, which means that there can be three relationships, for example, A and / or B can represent the existence of A alone, the existence of A and B together, and the existence of B alone. The character " / " generally represents an "or" relationship between the associated objects. "Including A, B and / or C" means including any one or any two or three of A, B and C.

[0035] It should be understood that, in the embodiments of the present application, "B corresponding to A", "B corresponding to A", "A corresponding to B" or "B corresponding to A" means that B is associated with A, and B can be determined according to A. Determining B according to A does not mean that B is determined only according to A, but also can be determined according to A and / or other information.

[0036] In modern virtual role-playing games, artificial intelligence technology is widely used. AI is not only used to enhance the challenge of enemy virtual characters, but also to support complex virtual character interactions.

[0037] Currently, game AI framework mainly implements the management of virtual character behavior through behavior tree and finite state machine. Behavior tree organizes character behavior through hierarchical structure, which is intuitive and manageable. Each node represents a decision point or action, and the relationship between nodes determines the execution order of behavior. Finite state machine (FSM) determines the action of the virtual character through state and state transition rules. The virtual character switches between different states to respond to game events. These technical methods usually combine with scripted interaction rules to ensure that the virtual character performs predetermined behavior in a specific situation.

[0038] However, the current behavior tree and FSM perform well in simple AI scenarios, but they are insufficient when dealing with complex and dynamic environments. The behavior of the virtual character does not change with the progress of the player, which limits the depth of the interactive experience. Due to the structural fixity, it is difficult for behavior tree and FSM to dynamically adjust the behavior priority and adapt to the changes in player behavior. At the same time, with the increase of game complexity, the number of states and nodes of behavior tree and FSM increases sharply, which is difficult to manage and maintain efficiently.

[0039] Based on the background technology, in order to improve the depth of interactive experience, the embodiment of the present application provides a method for controlling a virtual character in a game. The method is applied to a computer or a server, or other electronic devices capable of controlling a virtual character in a game. The embodiment of the present application is not specifically limited.

[0040] The technical solutions of the present application will be described in detail below through specific embodiments. It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0041] Figure 1 The flowchart of the method for controlling a virtual character in a game provided by the embodiment of the present application is shown in FIG. 1. As shown in FIG. 1, the method can include S101-S103. Figure 1

[0042] S101, in response to monitoring the occurrence of a game event, obtaining the current character level of a first virtual character, the first virtual character being a virtual character controlled by an intelligent agent in a game session, the character level changing with the progress of the game.

[0043] ​Exemplarily, after the game event is monitored, the agent can obtain the current character level of the first virtual character. The character level changes along with the game progress, for example, the character level can be raised or lowered along with the game progress. The game event can include a change in the environment of the game session and a change in the behavior of the virtual character in the game session. Generally referred to as a specific situation occurring in the game or an activity that the player can participate in, the game event can be any event occurring in the game progress, for example, a game event triggered by the behavior of the player, in a multi-character role-playing game, when the virtual character controlled by the player reaches a certain location, a dialogue or a battle with other virtual characters is triggered, or the life value, the physical value, and / or the hatred value of the virtual character changes, etc. It can also be a game event preset by the game developer in the development stage, for example, the developer will hide special achievements, props or additional story fragments, waiting for the player to trigger. In different game types, the specific meaning represented by the character level is also different. For example, in games of types similar to multi-character role-playing, social interaction, etc., the character level can represent the bond level, which can be used to measure and represent the depth or strength of the relationship between game characters. In games of types similar to battle arena games, fighting games, etc., the character level can represent the fighting power level. In games of types similar to simulation management games, puzzle adventure games, etc., the character level can represent the intelligence level.

[0044] S102, according to the current character level, calling the first behavior tree, the first behavior tree being a behavior tree corresponding to the current character level in a plurality of behavior trees preset for the agent, the behavior tree including a plurality of behaviors and trigger conditions corresponding to the behaviors.

[0045] Exemplarily, the agent can correspond to a plurality of behavior trees, the plurality of behavior trees corresponding to the agent are built in response to the building instruction. The behavior tree is a collection of a plurality of behaviors preset for a virtual character, and the behaviors included in the behavior tree are different for different virtual characters. Exemplarily, the virtual character is a tank character, and the behavior tree corresponding to the tank character can include a taunt behavior, a normal attack behavior, and a charge behavior, etc. The virtual character is a fast double-knife character, and the behavior tree corresponding to the fast double-knife character can include a fast attack behavior, a charge behavior, and a petrification behavior, etc. The behavior tree includes a plurality of behaviors and trigger conditions corresponding to the behaviors. For example, the behavior tree includes a taunt behavior, and the corresponding trigger condition is that the hostile character's hatred target changes. The behavior tree includes a healing behavior, and the corresponding trigger condition is that the life value of the teammate is lower than 50%. The first behavior tree is a behavior tree corresponding to the current character level in the plurality of behavior trees preset for the agent, and different behaviors will be executed for different character levels of the virtual character. For example, the combat behavior executed when the combat power level of the virtual character is high can be a combo behavior, and the combat behavior executed when the combat power level of the virtual character is low can be a single move. Based on this, in the embodiment, the agent corresponds to a plurality of behavior trees, and each behavior tree corresponds to a different level. For example, the agent controlling the first virtual character corresponds to a behavior tree A, a behavior tree B, and a behavior tree C. The behavior tree A corresponds to level 1, the behavior tree B corresponds to level 2, and the behavior tree C corresponds to level 3. When it is monitored that the current character level of the first virtual character is level 2, the behavior tree B is called.

[0046] Exemplarily, after the current character level is obtained, the first behavior tree can be called according to the obtained current character level. When the character level represents a bond level, the bond level can include a high bond level, a medium bond level, and a low bond level. If it is obtained that the current character level belongs to the high bond level, the behavior tree corresponding to the high bond level is the first behavior tree, and the behavior tree corresponding to the high bond level can be called, that is, the first behavior tree is called.

[0047] S103, in response to determining that the game event meets the trigger condition of the first behavior, controlling the first virtual character to execute the first behavior, the first behavior being a behavior in the plurality of behaviors included in the first behavior tree and matching the game event.

[0048] Exemplarily, the game event can be compared with the trigger condition of each behavior in the first behavior sub-tree, and when the game event satisfies the trigger condition of the first behavior, the first virtual role can be controlled to perform the first behavior. For example, the trigger condition of the first behavior is that the role level of the first virtual role is greater than a preset threshold and the distance between the second virtual role and the first virtual role is less than a preset threshold, and when the game event satisfies that the role level of the first virtual role is greater than the preset threshold and the distance between the second virtual role and the first virtual role is less than the preset threshold, the first virtual role can be controlled to perform the first behavior, and the second virtual role is a virtual role in the virtual scene which has a distance less than the preset threshold from the first virtual role.

[0049] Exemplarily, it is assumed that the first behavior tree includes a taunt behavior, a quick attack behavior and a healing behavior, the trigger condition of the taunt behavior is that the hostile role changes the hatred target, the trigger condition of the quick attack behavior is that the distance between the hostile role and the virtual role corresponding to the first behavior tree is less than 50 meters, and the trigger condition of the healing behavior is that the life value of the teammate is less than 50%. It is assumed that the monitored game event is that the distance between the virtual role corresponding to the first behavior tree and the hostile role is 35 meters, and the game event can be compared with the trigger conditions of the taunt behavior, the quick attack behavior and the healing behavior in turn, and it is concluded that the game event satisfies the trigger condition of the quick attack behavior, and the virtual role corresponding to the first behavior tree can be controlled to perform the quick attack behavior.

[0050] The embodiment of the present application can obtain the current role level of the first virtual role in response to monitoring the occurrence of the game event, and limit the change of the role level along with the game process, and then call the first behavior tree according to the current role level, and control the first virtual role to perform the first behavior in response to determining that the game event satisfies the trigger condition of the first behavior. The current role level of the virtual role can be used to call the first behavior tree corresponding to the current role level of the virtual role, so that the behavior of the virtual role changes along with the change of the role level, the growth of the virtual role is enhanced, and the depth of the interactive experience is improved.

[0051] In an optional implementation provided in the embodiment, the role level of the virtual role is not only related to the behavior performed by the virtual role, but also related to the reaction time of the virtual role when performing the behavior. Exemplarily, the higher the bond level of the virtual role is, the shorter the reaction time of the virtual role when performing the behavior is, that is, the interval between performing a task and entering the next task is also shorter. From the perspective of the player, the virtual role fights more energetically.

[0052] Figure 2 Another flowchart of the method for controlling a virtual role in a game provided by the embodiment of the present application is provided. As shown in Figure 2 the method can further include S201-S204.

[0053] S201. Obtain, according to the current character level, a first parameter corresponding to the current character level, the first parameter being used to represent an influence multiple of a reaction duration when the character level influences the first virtual character to perform a behavior.

[0054] S202. Obtain a basic reaction duration preset for the first virtual character and a basic character level of the first virtual character.

[0055] Exemplarily, before the step of controlling the first virtual character to perform the first behavior in response to determining that the game event meets the trigger condition of the first behavior, the embodiment can further include: obtaining, according to the current character level, a first parameter corresponding to the current character level, wherein the first parameter is used to represent an influence multiple of a reaction duration when the character level influences the first virtual character to perform a behavior. The reaction duration can also be understood as a global cooldown (GCD). The basic reaction duration preset for the first virtual character can be understood as a preset default value of the reaction duration of the first virtual character. The basic character level of the first virtual character is the character level when the first virtual character starts to enter a game match. The basic reaction duration of the virtual character and the first parameter can be set through a configuration parameter table (for example, a

DT_CharacterAI

[0056] S203. Determine, according to the first parameter, the basic reaction duration corresponding to the first virtual character, and the basic character level of the first virtual character, a changed reaction duration corresponding to the first virtual character under the current character level.

[0057] S204. Control the first virtual character to perform the first behavior after waiting for the changed reaction duration.

[0058] Exemplarily, after obtaining the first parameter, the basic reaction duration corresponding to the first virtual character, and the basic character level of the first virtual character, the changed reaction duration corresponding to the first virtual character under the current character level can be determined, and then the first virtual character is controlled to perform the first behavior after waiting for the changed reaction duration.

[0059] For example, when the character level represents the bond level, the bond level can include a high bond level, a medium bond level and a low bond level, and the higher the bond level, the shorter the global cooling time. Assuming that the preset basic reaction length of the first virtual character is 30 seconds, the basic character level of the first virtual character is 1, and the basic reaction length corresponding to the first virtual character can be reduced by 5% for each level of the character level, i.e., the first parameter is 5%, when the current character level of the first virtual character is 3, the changed reaction length corresponding to the first virtual character can be determined according to the first parameter, the basic reaction length corresponding to the first virtual character and the basic character level of the first virtual character, which is 27 seconds. Then control the first virtual character to wait for 27 seconds and execute the first behavior.

[0060] The embodiment obtains the first parameter corresponding to the current character level according to the current character level, and obtains the preset basic reaction length of the first virtual character and the basic character level of the first virtual character. According to the first parameter, the basic reaction length corresponding to the first virtual character and the basic character level of the first virtual character, the changed reaction length corresponding to the first virtual character under the current character level is determined. The first virtual character is controlled to wait for the changed reaction length, and then the first behavior is executed. By using the influence of the character level on the reaction length of the virtual character executing the behavior, the promotion degree of the fighting desire of the virtual character with different attack styles can be adjusted.

[0061] In an optional implementation, according to the behavior priority, each behavior tree is divided into a plurality of sub-trees, for example, the first behavior tree is divided into a first behavior sub-tree and a second behavior sub-tree, the first behavior sub-tree includes behaviors with high execution priority, such as rapid attack behaviors, charge behaviors, etc., therefore, the first behavior sub-tree can also be called a priority group, the second behavior sub-tree includes behaviors without execution priority, such as normal attacks, petrification, turning around in place, etc., and the second behavior sub-tree can also be called a general group, and the trigger condition of the behaviors in the second behavior sub-tree is that all game events can trigger. Of course, the first behavior tree can also be divided into a first behavior sub-tree, a second behavior sub-tree, a third behavior sub-tree, …, with more refined priority, so as to refine the performance behaviors of the first virtual character, which will not be described in detail here.

[0062] Figure 3 Another flowchart of the method for controlling a virtual character in a game provided by the embodiment of the present application is shown in FIG. 3. Figure 3 As shown in FIG. 3, before S103, the method can further include S301-S303.

[0063] S301, compare the game event with the trigger condition of each behavior in the first behavior sub-tree.

[0064] S302, if the game event meets the trigger condition of the second behavior, the second behavior is determined as the first behavior, the second behavior is a behavior in the first behavior sub-tree that matches the game event.

[0065] S303, if the game event does not meet the trigger condition of each behavior in the first behavior sub-tree, the third behavior is determined as the first behavior, the third behavior is any behavior in the second behavior sub-tree.

[0066] For example, the game event can be compared with the trigger condition of each behavior in the first behavior sub-tree in turn, if the game event meets the trigger condition of the second behavior, the second behavior is determined as the first behavior. If the game event does not meet the trigger condition of each behavior in the first behavior sub-tree, any behavior in the second behavior sub-tree can be selected as the first behavior. The trigger condition of the behavior in the second behavior sub-tree is that all game events can trigger.

[0067] For example, in a battle game, the behavior tree A corresponding to the agent controlling the virtual character X is called according to the current character level of the virtual character X, the behavior tree A includes a first behavior sub-tree and a second behavior sub-tree. The first behavior sub-tree includes a healing behavior, a taunt behavior and a charge behavior, and the second behavior sub-tree includes a general attack behavior and a petrification behavior. When the game event is that the life value of the teammate of the virtual character X is less than 80%, the trigger condition of the healing behavior in the first behavior sub-tree is that when the life value of the teammate of the virtual character X is less than 80%, the teammate is given continuous healing, and the game event meets the trigger condition of the healing behavior. The healing behavior can be determined as the first behavior. After comparing the game event with the trigger condition of each behavior in the first behavior sub-tree in turn, if the game event does not meet the trigger condition of each behavior in the first behavior sub-tree, the general attack can be selected as the first behavior, or the petrification can be selected as the first behavior.

[0068] The embodiment compares the game event with the trigger condition of each behavior in the first behavior sub-tree, if the game event meets the trigger condition of the second behavior, the second behavior is determined as the first behavior, if the game event does not meet the trigger condition of each behavior in the first behavior sub-tree, the third behavior is determined as the first behavior, and the second behavior is a behavior in the first behavior sub-tree that matches the game event, and the third behavior is any behavior in the second behavior sub-tree, which can ensure that the virtual character has a guaranteed behavior to execute after the game event occurs, thereby ensuring stable operation of the game process.

[0069] In another optional implementation provided in the embodiment, the first behavior tree can further include a third behavior subtree, the third behavior subtree including behaviors with the highest execution priority, such as taunting behaviors, healing behaviors, and quick attack behaviors, and thus the third behavior subtree can also be referred to as a stress group. The behaviors included in the first behavior subtree, the second behavior subtree, and the third behavior subtree can be the same, but the behaviors included in each behavior subtree correspond to different trigger conditions.

[0070] Figure 4 Another flowchart of the method for controlling a virtual character in a game provided in the embodiment is shown in FIG. 4. As shown in FIG. 4, the method can further include S401-S403. Figure 4

[0071] S401, in response to a time of occurrence of a game event being a preset detection time, comparing the game event with trigger conditions of each behavior in a third behavior subtree.

[0072] S402, in response to the game event satisfying a trigger condition of a fourth behavior, controlling the first virtual character to perform the fourth behavior, and after the fourth behavior is performed, performing a first behavior, the fourth behavior being a behavior in the third behavior subtree that matches the game event.

[0073] S403, if the game event does not satisfy the trigger condition of each behavior in the third behavior subtree, controlling the first virtual character to perform the first behavior.

[0074] Exemplarily, the first behavior tree further includes a third behavior subtree, the third behavior subtree including behaviors with the highest execution priority, and the third behavior subtree can also be referred to as a stress group. When it is detected that a game event occurs and a time of occurrence of the game event is a preset detection time, the game event can be compared with trigger conditions of each behavior in the third behavior subtree, and the game event can also be compared with trigger conditions of each behavior in the first behavior subtree. If the game event satisfies a trigger condition of a fourth behavior and a trigger condition of a first behavior at the same time, the first virtual character is controlled to perform the fourth behavior, and after the fourth behavior is performed, the first behavior is performed. If the game event does not satisfy the trigger condition of each behavior in the third behavior subtree and satisfies the trigger condition of the first behavior, the first virtual character is controlled to perform the first behavior. If the game event does not satisfy the trigger condition of each behavior in the third behavior subtree and the trigger condition of each behavior in the first behavior subtree, the first virtual character is controlled to perform a third behavior.

[0075] ​For example, when the occurrence time of the game event is the preset detection time, the game event is that the bond level of the virtual character X is greater than the preset threshold and the hatred target of the virtual character Y is not the virtual character X, and the virtual character Y is the enemy character of the virtual character X. The game event can be compared with the trigger condition of each behavior in the third behavior sub-tree and the trigger condition of each behavior in the first behavior sub-tree. If the game event meets the trigger condition of behavior A and the trigger condition of behavior B at the same time, the virtual character X is controlled to execute the taunt skill, and after the execution of the taunt skill ends, the charge skill is executed; wherein behavior A is a behavior in the third behavior sub-tree that matches the game event, behavior B is a behavior in the first behavior tree that matches the game event, behavior A triggers the taunt skill, and behavior B is the charge skill. If the game event does not meet the trigger condition of each behavior in the third behavior sub-tree and meets the trigger condition of behavior B, the virtual character X is controlled to execute the charge skill; if the game event does not meet the trigger condition of each behavior in the third behavior sub-tree and the trigger condition of each behavior in the first behavior sub-tree, the virtual character X is controlled to execute behavior C, that is, any one behavior in the second behavior sub-tree is executed.

[0076] In this embodiment, the game event is compared with the trigger condition of each behavior in the third behavior sub-tree in response to the occurrence time of the game event being the preset detection time, and the first virtual character is controlled to execute the fourth behavior in response to the game event meeting the trigger condition of the fourth behavior, and after the execution of the fourth behavior ends, the first behavior is executed. If the game event does not meet the trigger condition of each behavior in the third behavior sub-tree, the first virtual character is controlled to execute the first behavior. The game event can be detected in real time, the first virtual character is immediately controlled to execute the fourth behavior when the game event meets the trigger condition of the fourth behavior, the reaction speed and flexibility of the virtual character are improved, and the user's game experience is further improved.

[0077] In some embodiments, the above method further includes S501-S503.

[0078] S501, in response to the occurrence time of the game event not being the detection time, the first virtual character is controlled to execute the first behavior.

[0079] S502, in response to the game progress reaching the detection time, the game event is compared with the trigger condition of each behavior in the third behavior sub-tree.

[0080] S503, in response to the game event meeting the trigger condition of the fourth behavior, the first virtual character is controlled to stop executing the first behavior, execute the fourth behavior, and continue to execute the first behavior after the execution of the fourth behavior ends.

[0081] Exemplarily, when the occurrence of the game event is monitored and the occurrence time of the game event is not the preset detection time, the game event can be compared with the trigger condition of each behavior in the first behavior sub-tree first, and if the game event meets the trigger condition of the first behavior, the first virtual role is controlled to execute the first behavior. When the game progresses to the preset detection time, the game event is compared with the trigger condition of each behavior in the third behavior sub-tree, and if the game event meets the trigger condition of the fourth behavior, the first virtual role is controlled to stop executing the first behavior, immediately execute the fourth behavior, and continue to execute the first behavior after the execution of the fourth behavior ends.

[0082] Exemplarily, assuming that the occurrence time of the game event is the first time, the preset detection time is the second time, and the first time is a time 30 seconds before the second time. The game event can be compared with the trigger condition of each behavior in the first behavior sub-tree at the occurrence time of the game event, and if the game event meets the trigger condition of the first behavior, the first virtual role is controlled to execute the first behavior. Then, 30 seconds after the game progresses, the game event is compared with the trigger condition of each behavior in the third behavior sub-tree, and if the game event meets the trigger condition of the fourth behavior, the first virtual role is controlled to stop executing the first behavior, execute the fourth behavior, and continue to execute the first behavior after the execution of the fourth behavior ends.

[0083] The embodiment can detect the game event when the game event progresses to the preset detection time by responding to the occurrence time of the game event not being the detection time, controlling the first virtual role to execute the first behavior, responding to the game progressing to the detection time, comparing the game event with the trigger condition of each behavior in the third behavior sub-tree, and responding to the game event meeting the trigger condition of the fourth behavior, controlling the first virtual role to stop executing the first behavior, execute the fourth behavior, and continue to execute the first behavior after the execution of the fourth behavior ends, so as to achieve the purpose of detecting the game event in real time, and further improve the reaction speed and flexibility of the virtual role.

[0084] The above is a specific implementation mode of the control method of the virtual role in the game. In the specific implementation, the virtual role in the game can also be controlled by other feasible modes, and the embodiment of the application is not limited thereto.

[0085] In the exemplary embodiment, the embodiment of the application further provides a behavior tree, the behavior tree including a first behavior sub-tree, a second behavior sub-tree and a third behavior sub-tree, the first behavior sub-tree including behaviors with a high execution priority, the second behavior sub-tree including behaviors without an execution priority, and the third behavior sub-tree including behaviors with a highest execution priority; wherein the behavior tree corresponds to a preset role level.

[0086] Figure 5This is a schematic diagram of a behavior tree provided for an embodiment of this application. Figure 5 As shown, each character level corresponds to a behavior tree, and each behavior tree can include a first behavior subtree, a second behavior subtree, and a third behavior subtree. For example, when the character level represents the bond level, the bond level can include high bond level, medium bond level, and low bond level, and each bond level corresponds to a behavior tree.

[0087] During game operation, the behavior of virtual characters can be controlled according to the behavior tree provided in this application embodiment, which contains various behaviors and corresponding triggering conditions, thereby reducing computational redundancy, optimizing the use of computing resources, and effectively improving the game's operating efficiency.

The intelligent agent includes: a monitoring module, a behavior tree module, a matching module, and a control module.

[0089] The monitoring module is used to monitor game events.

[0090] The Behavior Tree module is used to maintain multiple behavior trees, which correspond to multiple role levels. Each behavior tree includes multiple behaviors and their corresponding triggering conditions.

[0091] The matching module is used to obtain the current character level of the first virtual character, which is a virtual character controlled by an intelligent agent in the game, and whose character level changes with the progress of the game; it is also used to call the first behavior tree according to the current character level, which is a behavior tree among multiple behavior trees that corresponds to the behavior of the current character level; it is also used to retrieve the first behavior that matches the game event from among the multiple behaviors included in the first behavior tree according to the game event.

[0092] The control module controls the first virtual character to perform the first action.

[0093] The intelligent agent provided in this application includes: a monitoring module, a behavior tree module, a matching module, and a control module. The intelligent agent can utilize the included modules to execute the control methods of the virtual character in the game, thereby supporting templated configuration, reducing repetitive work, and allowing for the expansion of the behavior tree, thus improving development efficiency and facilitating subsequent maintenance and updates.
