在Unity编辑器的Scene视图进行控制播放Animator，可以借助方法StartPlayback、StopPlayback、StartRecording和StopRecording，具体可以参照以下例子： 
创建一个带 Controller的Animator对象，可以看到此时人物呈现T型姿势。附上新脚本 EditAnimator，此为空脚本，如下：
C# Code

| using UnityEngine;
public class EditAnimator : MonoBehaviour
{
}

检视器效果如下：
点击" Bake"，可以看到此时人物姿势变成了动画状态的第一帧，如下所示：
拖动滑杆，即可播放当前时间的那一帧，如下所示：
点击" Play"，即可以自动播放整个动画，如下所示：
