将动画从动画<TextureRegion>移动到另一个Libgdx中

我需要知道如何将动画的内容移动到另一个动画中。

 animation1 = new Animation;
 animation2 = new Animation; 
 index = 0;
 tempFrames = TextureRegion.split(xxx, xxx.getWidth() / 4, xxx.getHeight() / 2);
        for (int i = 0; i < 4; i++) {
            for (int j = 0; j < 2; j++) {
                tempAnimationFrames[index] = tempFrames[j][i];
                index++;
            }
        }
 animation = new Animation<TextureRegion>(1f / 8f, tempAnimationFrames);

如何在animation2中移动动画animation1?
