[0004] However, the current way of managing virtual character behaviors through behavior trees and finite state machines means that the behavior of virtual characters does not change with the player's game progress, thus limiting the depth of the interactive experience. Summary of the invention

[0008] According to the current character level, the first behavior tree is called. The first behavior tree is a behavior tree corresponding to the current character level among multiple behavior trees preset for the intelligent agent. The behavior tree includes multiple behaviors and trigger conditions corresponding to the behaviors.

[0009] In response to determining that the game event meets the triggering condition of the first behavior, the first virtual character is controlled to perform the first behavior, where the first behavior is a behavior that matches the game event among the multiple behaviors included in the first behavior tree.

[0032] Many specific details are described in the following description to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present application, so the present application is not limited by the specific implementation disclosed below.

[0033] It should be noted that the terms "first", "second", "third", etc. in the claims, description and drawings of the present application are used to distinguish similar objects and are not used to describe a specific order or sequence. The data used in this way are interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including", "having" and their variants are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0034] It should be understood that in the embodiments of the present application, "at least one" refers to one or more, and "more than one" refers to two or more. "And / or" is merely a way to describe the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the previous and subsequent associated objects are in an "or" relationship. "Including A, B and / or C" means including any one, any two, or any 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 corresponds to B", or "B corresponds 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 determining B only according to A, and B can also 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 hostile virtual characters, but also to support complex virtual character interactions.

[0037] At present, game AI frameworks mainly use behavior trees and finite state machines to manage virtual character behaviors. Behavior trees organize character behaviors through a 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 behaviors. Finite state machines (FSMs) determine the actions of characters through states and state transition rules. Virtual characters switch between different states to respond to game events. These technical methods are usually combined with scripted interaction rules to ensure that virtual characters perform predetermined behaviors in specific situations.

[0038] However, currently behavior trees and FSMs perform well in simple AI scenarios, but they are insufficient when dealing with complex and dynamic environments. The behavior of virtual characters does not change with the player's game progress, which limits the depth of the interactive experience. In addition, due to their structural fixedness, behavior trees and FSMs are difficult to dynamically adjust behavior priorities and cannot adapt to changes in player behavior. At the same time, as the complexity of the game increases, the number of states and nodes of behavior trees and FSMs increases dramatically, making them difficult to manage and maintain efficiently.

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

[0040] The technical solution of the present application is 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 This is a flow chart of a method for controlling a virtual character in a game provided by an embodiment of the present application. Figure 1 As shown, the method may include S101-S103.

[0042] S101. In response to monitoring the occurrence of a game event, a current character level of a first virtual character is obtained, where the first virtual character is a virtual character controlled by an intelligent agent in a game match, and the character level changes with the progress of the game.

[0043] Exemplarily, after the agent detects the occurrence of a game event, the current character level of the first virtual character can be obtained. The character level changes with the progress of the game, for example, the character level can increase or decrease with the progress of the game. Game events may include: changes in the environment of the game match and changes in the behavior of the virtual character in the game match. Usually refers to a specific situation that occurs in the game or an activity that the player can participate in. The game event can be any event that occurs in the game process, for example, a game event triggered by the player's behavior. In a multi-role-playing game, when the virtual character controlled by the player reaches a certain location, it triggers a dialogue or battle with other virtual characters, or the life value, physical value, and / or hatred value of the virtual character changes. It can also be a game event preset by the game developer during 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 of the character level is also different. For example, in games such as multi-role-playing and social interaction, the character level can represent the bond level, and the bond level can be used to measure and represent the depth or strength of the relationship between game characters. In games such as battle arena games and fighting games, the character level can represent the combat effectiveness level. In games like business simulation games and puzzle adventure games, character level can represent intelligence level.

[0044] S102. Call a first behavior tree according to the current character level. The first behavior tree is a behavior tree corresponding to the current character level among a plurality of behavior trees preset for the agent. The behavior tree includes a plurality of behaviors and trigger conditions corresponding to the behaviors.

[0045] Exemplarily, an agent may correspond to multiple behavior trees, and the multiple behavior trees corresponding to the agent are constructed in response to the construction instruction. A behavior tree is a set of multiple behaviors preset for a virtual character. Different virtual characters have different behaviors included in the behavior tree. For example, if the virtual character is a tank character, its corresponding behavior tree may include taunting behavior, normal attack behavior, and charge behavior, etc., and if the virtual character is a fast double-blade character, its corresponding behavior tree may include fast attack behavior, charge behavior, and petrification behavior, etc. A behavior tree includes multiple behaviors and trigger conditions corresponding to the behaviors. For example, the behavior included in the behavior tree is a taunting behavior, and the corresponding trigger condition is that the target of hatred of the hostile character changes; the behavior included in the behavior tree is a healing behavior, and the corresponding trigger condition is that the health value of the teammate is less than 50%. The first behavior tree is a behavior tree corresponding to the current character level among the multiple behavior trees preset for the agent. Different virtual characters will execute different behaviors when their role levels are different. For example, when the combat power level of the virtual character is high, the combat behavior executed may be a combo behavior, and when the combat power level of the virtual character is low, the combat behavior executed may be a single move. Based on this, in this embodiment, the agent corresponds to multiple behavior trees, and each behavior tree corresponds to a different level. For example, the agent controlling the first virtual character corresponds to behavior tree A, behavior tree B, and behavior tree C. Behavior tree A corresponds to level 1, behavior tree B corresponds to level 2, and behavior tree C corresponds to level 3. When it is detected that the current role level of the first virtual character is level 2, behavior tree B is called.

[0046] For example, after obtaining the current character level, the first behavior tree can be called according to the obtained current character level. 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. If the current character level is obtained to be a 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 triggering condition of the first behavior, control the first virtual character to execute the first behavior, where the first behavior is a behavior that matches the game event among multiple behaviors included in the first behavior tree.

[0048] Exemplarily, the game event can be compared with the triggering condition of each behavior in the first behavior subtree, and when the game event meets the triggering condition of the first behavior, the first virtual character can be controlled to perform the first behavior. For example, the triggering condition of the first behavior is that the character level of the first virtual character is greater than a preset threshold and the distance between the second virtual character and the first virtual character is less than a preset threshold. When the game event meets the condition that the character level of the first virtual character is greater than the preset threshold and the distance between the second virtual character and the first virtual character is less than the preset threshold, the first virtual character can be controlled to perform the first behavior, and the second virtual character is a virtual character whose distance from the first virtual character in the virtual scene is less than the preset threshold.

[0049] For example, assuming that the first behavior tree includes taunting behavior, quick attack behavior and healing behavior, the triggering condition of taunting behavior is that the hostile character's target of hatred changes, the triggering condition of quick attack behavior is that the distance between the hostile character and the virtual character corresponding to the first behavior tree is less than 50 meters, and the triggering condition of healing behavior is that the teammate's health value is less than 50%. Assuming that the monitored game event is that the distance between the virtual character corresponding to the first behavior tree and the hostile character is 35 meters, the game event can be compared with the triggering conditions of taunting behavior, quick attack behavior and healing behavior in turn, and it is concluded that the game event meets the triggering condition of quick attack behavior, and the virtual character corresponding to the first behavior tree can be controlled to perform quick attack behavior.

[0050] The embodiment of the present application obtains the current character level of the first virtual character in response to monitoring the occurrence of a game event, and limits the character level to change with the game process, then calls the first behavior tree according to the current character level, and controls the first virtual character to perform the first behavior in response to determining that the game event satisfies the triggering condition of the first behavior. The first behavior tree corresponding to the current character level of the virtual character can be called according to the current character level of the virtual character, so that the behavior of the virtual character changes with the change of the character level, thereby enhancing the growth of the virtual character and improving the depth of the interactive experience.

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

[0052] Figure 2 Another flow chart of the method for controlling a virtual character in a game provided by an embodiment of the present application. Figure 2 As shown, the method may also include S201-S204.

[0053] S201. According to the current character level, obtain a first parameter corresponding to the current character level, where the first parameter is used to represent the influence ratio of the character level on the reaction time of the first virtual character when performing an action.

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

[0055] Exemplarily, before the above step: in response to determining that the game event satisfies the triggering condition of the first behavior, controlling the first virtual character to perform the first behavior, the present embodiment may further include: obtaining a first parameter corresponding to the current character level according to the current character level, wherein the first parameter is used to characterize the influence multiplier of the character level on the reaction time when the first virtual character performs the behavior. The reaction time can also be understood as the global cooldown (GCD). The basic reaction time preset for the first virtual character can be understood as the preset default value of the reaction time 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 the game. The basic reaction time and the first parameter of the virtual character can be set by configuring a parameter table (e.g., [DT_CharacterAI] table). After determining the current character level of the first virtual character, the first parameter corresponding to the current character level and the basic reaction time of the first virtual character can be obtained in the above parameter table according to the current character level of the first virtual character.

[0056] S203: Determine, according to the first parameter, the basic reaction time corresponding to the first virtual character and the basic character level of the first virtual character, the change reaction time corresponding to the first virtual character at the current character level.

[0057] S204: Control the first virtual character to execute a first behavior after waiting for the change reaction time.

[0058] Exemplarily, after obtaining the first parameter, the basic reaction time corresponding to the first virtual character and the basic character level of the first virtual character, the change reaction time corresponding to the first virtual character at the current character level can be determined, and then the first virtual character is controlled to wait for the change reaction time before executing the first behavior.

[0059] For example, when the character level represents the bond level, the bond level may include a high bond level, a medium bond level, and a low bond level. The higher the bond level, the shorter the global cooling time. Assuming that the preset basic reaction time for the first virtual character is 30 seconds, the basic character level of the first virtual character is 1, and each level of the character level can reduce the basic reaction time corresponding to the first virtual character by 5%, that is, the first parameter is 5%. When the current character level of the first virtual character is 3, the first parameter, the basic reaction time corresponding to the first virtual character, and the basic character level of the first virtual character can be used to determine that the change reaction time corresponding to the first virtual character is 27 seconds. Then control the first virtual character to wait for 27 seconds and then execute the first behavior.

[0060] This embodiment obtains a first parameter corresponding to the current character level according to the current character level, and obtains a basic reaction time preset for the first virtual character and a basic character level of the first virtual character; determines a change reaction time corresponding to the first virtual character under the current character level according to the first parameter, the basic reaction time corresponding to the first virtual character, and the basic character level of the first virtual character; controls the first virtual character to execute a first behavior after waiting for the change reaction time, and utilizes the influence of the character level on the reaction time when the virtual character executes the behavior to adjust the degree of improvement in the fighting desire of virtual characters with different attack styles.

[0061] In an optional implementation, each behavior tree is divided into multiple subtrees according to the behavior priority. For example, the first behavior tree is divided into the first behavior subtree and the second behavior subtree. The execution priority of the behaviors included in the first behavior subtree is high priority, such as fast attack behavior, charge behavior, etc. Therefore, the first behavior subtree can also be called a priority group. The behaviors included in the second behavior subtree have no execution priority, such as ordinary attack, petrification, and spinning in place. The second behavior subtree can also be called a general group. The triggering conditions of the behaviors in the second behavior subtree are that all game events can be triggered. Of course, the first behavior tree can also be divided into the first behavior subtree, the second behavior subtree, the third behavior subtree, etc. with more refined priorities to refine the performance behavior of the first virtual character, which will not be explained in detail here.

[0062] Figure 3 This is another flow chart of a method for controlling a virtual character in a game provided by an embodiment of the present application. Figure 3 As shown, before the above S103, the method may further include S301-S303.

[0063] S301, comparing the game event with the triggering condition of each behavior in the first behavior subtree.

[0064] S302: If the game event meets the triggering condition of the second behavior, the second behavior is determined as the first behavior, and the second behavior is a behavior that matches the game event among the multiple behaviors included in the first behavior subtree.

[0065] S303: If the game event does not satisfy the triggering condition of each behavior in the first behavior subtree, the third behavior is determined as the first behavior, and the third behavior is any behavior in the second behavior subtree.

[0066] For example, the game event can be compared with the triggering conditions of each behavior in the first behavior subtree in turn. If the game event meets the triggering conditions of the second behavior, the second behavior is determined as the first behavior. If the game event does not meet the triggering conditions of each behavior in the first behavior subtree, any behavior in the second behavior subtree can be selected as the first behavior. The triggering conditions of the behaviors in the second behavior subtree are that all game events can be triggered.

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

[0068] This embodiment compares the game event with the triggering condition of each behavior in the first behavior subtree; if the game event meets the triggering condition of the second behavior, the second behavior is determined as the first behavior; if the game event does not meet the triggering condition of each behavior in the first behavior subtree, the third behavior is determined as the first behavior, and it is defined that the second behavior is a behavior that matches the game event among the multiple behaviors included in the first behavior subtree, and the third behavior is any behavior in the second behavior subtree. This can ensure that the virtual character has a guaranteed behavior to execute after the game event occurs, thereby ensuring the stable operation of the game process.

[0069] In another optional implementation provided by this embodiment, the first behavior tree may further include a third behavior subtree, and the execution priority of the behaviors included in the third behavior subtree is the highest priority, such as taunting behavior, healing behavior, and rapid attack behavior, so the third behavior subtree may also be called a stress group. The behaviors included in the first behavior subtree, the second behavior subtree, and the third behavior subtree may be the same, but the trigger conditions corresponding to the behaviors included in each behavior subtree are different.

[0070] Figure 4 This is another flow chart of a method for controlling a virtual character in a game provided by an embodiment of the present application. Figure 4 As shown, the method may also include S401-S403.

[0071] S401: In response to the occurrence time of the game event being a preset detection time, the game event is compared with the triggering condition of each behavior in the third behavior subtree.

[0072] S402, in response to the game event satisfying the triggering condition of the fourth behavior, controlling the first virtual character to execute the fourth behavior, and after the fourth behavior is executed, executing the first behavior, the fourth behavior is a behavior that matches the game event among the multiple behaviors included in the third behavior subtree.

[0073] S403: If the game event does not satisfy the triggering condition of each behavior in the third behavior subtree, control the first virtual character to execute the first behavior.

[0074] Exemplarily, the first behavior tree also includes a third behavior subtree, and the execution priority of the behavior included in the third behavior subtree is the highest priority. The third behavior subtree can also be called a stress group. When the occurrence of a game event is monitored and the occurrence time of the game event is a preset detection time, the game event can be compared with the triggering condition of each behavior in the third behavior subtree, and the game event can be compared with the triggering condition of each behavior in the first behavior subtree. If the game event satisfies the triggering condition of the fourth behavior and the triggering condition of the first behavior at the same time, the first virtual character is controlled to execute the fourth behavior, and after the fourth behavior is executed, the first behavior is executed; if the game event does not meet the triggering condition of each behavior in the third behavior subtree, and meets the triggering condition of the first behavior, the first virtual character is controlled to execute the first behavior; if the game event does not meet the triggering condition of each behavior in the third behavior subtree and the triggering condition of each behavior in the first behavior subtree, the first virtual character is controlled to execute the third behavior.

[0075] For example, when the occurrence time of the game event is monitored to be the preset detection time, the game event is that the bond level of virtual character X is greater than the preset threshold and the target of hatred of virtual character Y is not virtual character X, and virtual character Y is the enemy of virtual character X. The game event can be compared with the triggering conditions of each behavior in the third behavior subtree and the triggering conditions of each behavior in the first behavior subtree. If the game event satisfies both the triggering conditions of behavior A and the triggering conditions of behavior B, the virtual character X is controlled to execute the taunt skill, and after the execution of the taunt skill is completed, the charge skill is executed; wherein behavior A is a behavior that matches the above game event among the multiple behaviors included in the third behavior subtree, and behavior B is a behavior that matches the above game event among the multiple behaviors included in the first behavior tree, behavior A triggers the taunt skill, and behavior B is the charge skill. If the game event does not meet the triggering conditions of each behavior in the third behavior subtree, but meets the triggering conditions of behavior B, the virtual character X is controlled to perform the charge skill; if the game event does not meet the triggering conditions of each behavior in the third behavior subtree and the triggering conditions of each behavior in the first behavior subtree, the virtual character X is controlled to perform behavior C, that is, the virtual character X is controlled to perform any behavior in the second behavior subtree.

[0076] This embodiment responds to the occurrence time of the game event as a preset detection time, compares the game event with the triggering conditions of each behavior in the third behavior subtree; in response to the game event satisfying the triggering condition of the fourth behavior, controls the first virtual character to execute the fourth behavior, and executes the first behavior after the fourth behavior is executed; if the game event does not satisfy the triggering conditions of each behavior in the third behavior subtree, controls the first virtual character to execute the first behavior, wherein the fourth behavior is a behavior that matches the game event among the multiple behaviors included in the third behavior tree, and can detect the game event in real time, and when the game event satisfies the triggering condition of the fourth behavior, controls the first virtual character to immediately execute the fourth behavior, thereby improving the reaction speed and flexibility of the virtual character and further enhancing the user's gaming experience.

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

[0078] S501: In response to the occurrence time of the game event not being the detection time, control the first virtual character to execute a first behavior.

[0079] S502: In response to the game process reaching the detection moment, the game event is compared with the triggering condition of each behavior in the third behavior subtree.

[0080] S503: In response to the game event satisfying the triggering 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 is completed.

[0081] For example, when the occurrence of a game event is monitored and the occurrence time of the game event is not a preset detection time, the game event can be compared with the triggering conditions of each behavior in the first behavior subtree. If the game event meets the triggering conditions of the first behavior, the first virtual character is controlled to perform the first behavior. When the game process reaches the preset detection time, the game event is compared with the triggering conditions of each behavior in the third behavior subtree. If the game event meets the triggering conditions of the fourth behavior, the first virtual character is controlled to stop performing the first behavior, immediately perform the fourth behavior, and continue to perform the first behavior after the fourth behavior is completed.

[0082] For example, assuming that the occurrence time of the game event is the first moment, the preset detection time is the second moment, and the first moment is 30 seconds before the second moment. At the time of the game event, the game event can be compared with the triggering conditions of each behavior in the first behavior subtree. If the game event meets the triggering conditions of the first behavior, the first virtual character is controlled to perform the first behavior. Then, after 30 seconds of the game process, the game event is compared with the triggering conditions of each behavior in the third behavior subtree. If the game event meets the triggering conditions of the fourth behavior, the first virtual character is controlled to stop performing the first behavior, perform the fourth behavior, and continue to perform the first behavior after the fourth behavior is completed.

[0083] In response to the occurrence moment of the game event being not the detection moment, this embodiment controls the first virtual character to execute the first behavior; in response to the game process reaching the detection moment, compares the game event with the triggering condition of each behavior in the third behavior subtree; in response to the game event satisfying the triggering condition of the fourth behavior, controls the first virtual character to stop executing the first behavior, execute the fourth behavior, and continue executing the first behavior after the fourth behavior is executed. The game event can be detected when the game event reaches the preset detection moment, thereby achieving the purpose of real-time detection of game events and further improving the reaction speed and flexibility of the virtual character.

[0084] The above is a specific implementation of a method for controlling a virtual character in a game.
