Behavior Designer扩展

BehaviorManager.instance.Tick(behaviorTree); 卸载update里u3d直接卡死 = =

SharedVariable直接赋值会改变他的引用关系，必须用XXX.Value赋值 = =

两种自定义Task:  Task 和 Parent Tasks

基础task流程 ( Conditional Task  和   Action Task )

Parent Tasks

// The maximum number of children a parent task can have. Will usually be 1 or int.MaxValue
public virtual int MaxChildren();

// Boolean value to determine if the current task is a parallel task
public virtual bool CanRunParallelChildren();

// The index of the currently active child
public virtual int CurrentChildIndex();

// Boolean value to determine if the current task can execute
public virtual bool CanExecute();

// Apply a decorator to the executed status
public virtual TaskStatus Decorate(TaskStatus status);

// Notifies the parent task that the child has been executed and has a status of childStatus
public virtual void OnChildExecuted(TaskStatus childStatus);

// Notifies the parent task that the child at index childIndex has been executed and has a status of childStatus
public virtual void OnChildExecuted(int childIndex, TaskStatus childStatus);

// Notifies the task that the child has started to run
public virtual void OnChildStarted();

// Notifies the parallel task that the child at index childIndex has started to run
public virtual void OnChildStarted(int childIndex);

// Some parent tasks need to be able to override the status, such as parallel tasks
public virtual TaskStatus OverrideStatus(TaskStatus status);

// The interrupt node will override the status if it has been interrupted.
public virtual TaskStatus OverrideStatus();

// Notifies the composite task that an conditional abort has been triggered and the child index should reset
public virtual void OnConditionalAbort(int childIndex);
