解决unity动画系统中多次按键之后trigger触发多次的问题_resettrigger unity

在unity动画系统中，例如用trigger控制人物跳跃动画，当你快速按下相应按键时，可能trigger会触发多次，例如：

解决方法如下：

在ground状态下新增一个名为FSMClearSignals的脚本，代码如下

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
 
public class FSMClearSignals : StateMachineBehaviour {
 
    public string[] clearAtEnter;
    public string[] cleatAtExit;
 
    // OnStateEnter is called when a transition starts and the state machine starts to evaluate this state
    override public void OnStateEnter(Animator animator, AnimatorStateInfo stateInfo, int layerIndex)
    {
        foreach (var signal in clearAtEnter)
        {
            animator.ResetTrigger(signal);//重置trigger
        }
    }
 
    // OnStateUpdate is called on each Update frame between OnStateEnter and OnStateExit callbacks
    //override public void OnStateUpdate(Animator animator, AnimatorStateInfo stateInfo, int layerIndex) {
    //
    //}
 
    // OnStateExit is called when a transition ends and the state machine finishes evaluating this state
    override public void OnStateExit(Animator animator, AnimatorStateInfo stateInfo, int layerIndex)
    {
        foreach (var signal in clearAtEnter)
        {
            animator.ResetTrigger(signal);//重置trigger
        }
    }
 
    // OnStateMove is called right after Animator.OnAnimatorMove(). Code that processes and affects root motion should be implemented here
    //override public void OnStateMove(Animator animator, AnimatorStateInfo stateInfo, int layerIndex) {
    //
    //}
 
    // OnStateIK is called right after Animator.OnAnimatorIK(). Code that sets up animation IK (inverse kinematics) should be implemented here.
    //override public void OnStateIK(Animator animator, AnimatorStateInfo stateInfo, int layerIndex) {
    //
    //}
}
