java - 如何渲染动画的特定帧？

Question

我想要使用动画渲染特定帧

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

例如，当我单击某处时，我希望动画更改为第二个图像，而不仅仅是循环 TextureAtlas 中的帧。

更新

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

坐标

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
            }
         }

只需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);
