我希望使用动画

渲染特定的帧

batch.draw(Animation.getKeyFrame(time,true),x,y);

例如，当我点击某个地方时，我希望动画更改为第二个图像而不是仅仅循环来自TextureAtlas的帧。

public void newBitter(){
        Sprite spr= Pools.obtain(Sprite.class);
        bitters.add(spr);
        spr.setPosition(rX, Y);
    } //the sprites are not rendered I just need them for the c

oordinates

while(Iterator.hasNext()){
            Sprite sprite=Iterator.next();
            batch.draw(frames[frameCounter],sprite.getX(),sprite.getY());
            sprite.translateY(-300 * deltaTime);

            if(touched==true && gameObj.pos.x>=sprite.getX() && gameObj.pos.x<=sprite.getX()+82
                    && gameObj.pos.y>=sprite.getY() && gameObj.pos.y<=sprite.getY()+82){
                frameCounter=1;
                } //here I render the frames/animation based on the sprite coordinates, If the sprite is clicked the counter for the frames ==1 or +=1
            }
         }

将所有动画帧保留在集合中，然后根据以下条件修改当前帧ID：

    Animation animation;

    ...

    TextureRegion[] frames = animation.getKeyFrames();
    int currentFrameId = 0;

    ...

    if( clickedOnSomething() ) //let the clickedOnSomething method return true when clicked
    {
        currentFrameId++; //or another change due to some conditions
    }

    ...

    batch.draw(frames[currentFrameId], x, y);

如何渲染动画的特定帧？
