Unity编辑器 - Rigidbody动力学Bake到AnimationClip

Unity文档移动平台优化部分提到Physics对CPU的消耗较大

将动力学的特效如破碎等Bake成动画也是优化性能的手段之一，在Unity中可以很方便的将刚体动力学录制成AnimationClip。

using UnityEditor.Experimental.Animations;

using UnityEngine;

using UnityEditor;

public class TransformAnimRecorder : MonoBehaviour {

    private AnimationClip clip;

    //停止录制时保存Clip

    public bool record = true;

    private GameObjectRecorder _recorder;

    void Start() {

        clip = new AnimationClip();

        _recorder = new GameObjectRecorder();

        _recorder.root = gameObject;

        _recorder.BindComponent<Transform>(gameObject, true);

    }

    void LateUpdate() {

        if (clip == null)

            return;

        if (record) {

            _recorder.TakeSnapshot(Time.deltaTime);

        }

        else if (_recorder.isRecording) {

            _recorder.SaveToClip(clip);

            _recorder.ResetRecording();

            AssetDatabase.CreateAsset(clip, "Assets/RecordTest/testClip.anim");

        }

    }

}
