1、切换到动画器

点击make transition和exit关联起来

2、设置参数

勾选掉Has Exit Time

3、脚本给动画器传参

using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class Fly : MonoBehaviour
{//获取小鸟（刚体）private Rigidbody2D bird;//速度public float speed;//跳跃public float jump;//是否存活public static bool life = true;//获取动画器private Animator animator;// Start is called before the first frame updatevoid Start(){bird = GetComponent<Rigidbody2D>();animator = GetComponent<Animator>();}// Update is called once per framevoid Update(){//村换的时候才能运动if (life) { bird.velocity = new Vector2(speed, bird.velocity.y);//鼠标点击给目标一个纵向速度if (Input.GetMouseButtonDown(0)){bird.velocity = new Vector2(bird.velocity.x, jump);}}}//如果碰撞器撞到了某个物体private void OnCollisionEnter2D(Collision2D collision){life = false;animator.SetBool("life", false);}
}
