class in UnityEngine/Inherits from: ScriptableObject

Description 描述

tateMachineBehaviour is a component that can be added to a state machine state. It's the base class every script on a state derives from.

状态机行为是个可以添加状态机状态的组件。这是来自基类上的每个脚本派生的状态。

By default the Animator does instantiate a new instance of each behaviour define in the controller. The class attribute SharedBetweenAnimatorsAttribute control how behaviours are instantiated.

默认情况下，Animator示例化一个新的实例的每个行为在控制器中定义。该类属性SharedBetweenAnimatorsAttribute 控制如何实例化该行为。

StateMachineBehaviour has some predefined messages: OnStateEnter, OnStateExit, OnStateIK, OnStateMove, OnStateUpdate.

StateMachineBehaviour 有一些预定义的信息：OnStateEnter, OnStateExit, OnStateIK, OnStateMove, OnStateUpdate。

JavaScript:

#pragma strict
public class AttackBehaviour extends StateMachineBehaviour {
	public var particle: GameObject;
	public var radius: float;
	public var power: float;
	protected var clone: GameObject;
	public override function OnStateEnter(animator: Animator, stateInfo: AnimatorStateInfo, layerIndex: int) {
		clone = Instantiate(particle, animator.rootPosition, Quaternion.identity) as GameObject;
		var rb: var = clone.GetComponent.<Rigidbody>();
		rb.AddExplosionForce(power, animator.rootPosition, radius, 3.0f);
	}
	public override function OnStateExit(animator: Animator, stateInfo: AnimatorStateInfo, layerIndex: int) {
		Destroy(clone);
	}
	public override function OnStateUpdate(animator: Animator, stateInfo: AnimatorStateInfo, layerIndex: int) {
		Debug.Log("On Attack Update ");
	}
	public override function OnStateMove(animator: Animator, stateInfo: AnimatorStateInfo, layerIndex: int) {
		Debug.Log("On Attack Move ");
	}
	public override function OnStateIK(animator: Animator, stateInfo: AnimatorStateInfo, layerIndex: int) {
		Debug.Log("On Attack IK ");
	}
}

C#:

using UnityEngine;
 
public class AttackBehaviour : StateMachineBehaviour
{
	public GameObject particle;
	public float radius;
	public float power;
 
	protected GameObject clone;
 
	override public void OnStateEnter(Animator animator, AnimatorStateInfo stateInfo, int layerIndex)
	{
		clone = Instantiate(particle, animator.rootPosition, Quaternion.identity) as GameObject;
		var rb = clone.GetComponent<Rigidbody>();
		rb.AddExplosionForce(power, animator.rootPosition, radius, 3.0f);
	}
	override public void OnStateExit(Animator animator, AnimatorStateInfo stateInfo, int layerIndex)
	{
		Destroy(clone);
	}
	override public void OnStateUpdate(Animator animator, AnimatorStateInfo stateInfo, int layerIndex)
	{
		Debug.Log("On Attack Update ");
	}
	override public void OnStateMove(Animator animator, AnimatorStateInfo stateInfo, int layerIndex)
	{
		Debug.Log("On Attack Move ");
	}
	override public void OnStateIK(Animator animator, AnimatorStateInfo stateInfo, int layerIndex)

Public Functions 公共函数

OnStateMachineEnter	Called on the first Update frame when making a transition to a StateMachine. This is not called when making a transition into a StateMachine sub-state. 变换转进入状态机时调用该属性。变换进入状态机的子状态时不会调用该属性。
OnStateMachineExit	Called on the last Update frame when making a transition out of a StateMachine. This is not called when making a transition into a StateMachine sub-state. 变换超出状态机时调用该属性。变换在状态机的子状态下不会调用该属性。。

Messages 消息

OnStateEnter	Called on the first Update frame when a statemachine evaluate this state. 状态机评估进入状态时调用该属性。
OnStateExit	Called on the last update frame when a statemachine evaluate this state. 当状态机评估停止状态时调用该属性。
OnStateIK	Called right after MonoBehaviour.OnAnimatorIK. MonoBehaviour.OnAnimatorIK之后调用该属性。
OnStateMove	Called right after MonoBehaviour.OnAnimatorMove. MonoBehaviour.OnAnimatorMove之后调用该属性。
OnStateUpdate	Called at each Update frame except for the first and last frame. 除了开始和最后一帧，每次更新时调用。
