[游戏开发]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;
}
