let state: AnimatorState = new AnimatorState();

state.name = key;// walk/idle/attack

state.clipStart = clipStart;

this._animator.play(this._action);

this._animator.getDefaultState().clip.islooping = this._action=="walk" || this._action=="idle"

state.clip = this._animator.getDefaultState().clip;
