[]3D中的Animator如何从指定的某一帧开始播放动画

            animator.stop();

			var percent:Number = animator.currentFrameTime / animator.getClip("Draw").duration();

			//trace("currentFrameTime: " + animator.currentFrameTime + " endTime: " + animator.getClip("Draw").duration());

			var totalAnimationClip:AnimationClip = animator.getClip("Shoot");

			//动画总时长

			var maxTime:Number = totalAnimationClip.duration();

			//每帧间隔

			var frameInterval:int = 1 / animator.cacheFrameRate;

			//总帧数

			var endFrame:int = Math.floor(maxTime / frameInterval);

			//计算开始帧

			var startFrame:int = Math.floor(endFrame * (1 - percent));

			animator.addClip(totalAnimationClip,"runShoot",startFrame);

			animator.on(Event.STOPPED, this, this.removeClip);

			animator.on(Event.COMPLETE, this, this.removeClip);

			animator.play("runShoot");
