批量创建Timeline

创建Prefab

	
static void CreatePrefab(GameObject go, string path, string name)


	
{


	
    //先创建一个空的预制物体


	
    //预制物体保存在工程中路径，可以修改("Assets/" + name + ".prefab");


	
    GameObject tempPrefab = PrefabUtility.CreatePrefab(path + name + ".prefab", go);


	
}

创建Playable

	
static TimelineAsset CreateTimelineAsset(string path, string name)


	
{


	
    var asset = TimelineAsset.CreateInstance<TimelineAsset>();


	
    AssetDatabase.CreateAsset(asset, path + name +".playable");


	
    var track = asset.CreateTrack<InitializeTrackAsset>(null);


	
    var clip = track.CreateClip<InitializeClipAsset>();


	
    AssetDatabase.SaveAssets();


	
    return asset;


	
}
