unity 动态播放音频 unity播放动图

相信你可能遇到这样的情况，在用Animator的时候，播放一个动画，调用了一下SetInteger之后，动画就鬼畜了，这是因为没有及时重置动画状态的问题，SetInteger进入状态A后，假设要让它回调状态B，必须至少隔一帧然后SetInteger到B
这里教大家正确的姿势

Animator状态机

现在，假设我们已经有了各个动画文件，比如出场、站立、跑、攻击等，用Animator把各个状态组织起来

设置两个参数：Speed, Action

设置状态过渡的条件

用法

接下来就是用代码控制动画了：接口主要是SetInteger和GetInteger 为了方便控制，可以封装一个类，我这里封装好了一个CharacterAniLogic.cs（在文章最下面）

现在，假设现在我们有一个角色GameObject，身上有一个Animator组件
先创建一个角色控制的脚本: PlayerBhv.cs，挂在角色GameObject上
然后在PlayerBhv中通过CharacterAniLogic组件来控制动画播放
注：CharacterAniLogic可以动态AddComponent，也可以事先挂好然后GetComponent 使用示例

// PlayerBhv.cs

using UnityEngine;
using System.Collections;
using System.Collections.Generic;

public class PlayerBhv : MonoBehaviour
{
	private CharacterAniLogic m_aniCtr;
	public GameObject modelObj;
	
	void Start()
	{
		var ani = modelObj.GetComponent<Animator>();
		m_aniCtr = modelObj.AddComponent<CharacterAniLogic>();
		m_aniCtr.Init(ani);
	}
	
	void Update()
	{
		#region Speed类型的动画
		if(Input.GetButtonDown(KeyCode.A))
		{
			//播放跑动作
			m_aniCtr.PlayRun();
		}
		else if(Input.GetButtonDown(KeyCode.B))
		{
			//播放站立动作
			m_aniCtr.PlayIdle();
		}
		#endregion
		
		#region Action类型的动画
		//Action类型的动画，封装类内部做了队列播放///
		//播放攻击动作，具体Action的值看你的Animator的过渡条件编辑
		if(Input.GetButtonDown(KeyCode.C))
		{
			m_aniCtr.PlayAnimation(10020);
		}
		else if(Input.GetButtonDown(KeyCode.D))
		{
			m_aniCtr.PlayAnimation(10030);
		}
		#endregion
	}
}
