Question

我正在尝试使用具有各种动作状态的png文件制作动画。我的问题是，渲染时图片彼此重叠。有解决方案，我只能显示一张照片吗？我使用LibGDX库。

@Override public void show()
{
    batch = new SpriteBatch();
    img = new Texture("core/assets/ghosty.png");

    regions = TextureRegion.split(img, 32, 32);
    sprite = new Sprite (regions[0][0]);
    Timer.schedule(new Timer.Task(){

        @Override
        public void run(){
            frame++;
            if (frame>27){
                frame = 0;
                if (zeile ==1){
                    zeile = 0;
                }
                else
                {
                    zeile = 1;
                }
            }
            sprite.setRegion(regions[zeile][frame]);
        }

    }, 0, 1/20f);

}

@Override public void render(float delta)
{
    //stage.draw();

    batch.begin();

    sprite.draw(batch);

    batch.end();
}

您不需要额外的Timer任务和Sprite，而是需要Animation<>。

以下是渲染动画的一个小示例：

private SpriteBatch batch;
private Texture img;
private Animation<TextureRegion> animation;
private TextureRegion[][] regions;
private Array<TextureRegion> frames;

@Override
public void show() {
    batch = new SpriteBatch();
    img = new Texture(Gdx.files.internal("ghosty.png")); //Get Texture from asset folder
    regions = TextureRegion.split(img, 32, 32);
    frames = new Array<TextureRegion>();
    int rows = 5, columns = 5; //How many rows and columns the region have

    //Fill Frames array with the regions of Texture
    for(int i = 0; i < rows; i++){
        for(int j = 0; j < columns; j++){
            frames.add(regions[i][j]);
        }
    }

    //Create Animation. 0.1f is the time how long a frame will occur,
    //is the animation to fast set this number to a higher value
    //so the single frames will stay for a longer time
    animation = new  Animation<TextureRegion>(0.1f, frames, Animation.PlayMode.LOOP);
}

private float stateTime = 0;

@Override
public void render(float delta) {
    //Clear the screen
    Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
    //update state time so animation will go further
    stateTime += delta;

    batch.begin();
    //Draw the current frame
    batch.draw(animation.getKeyFrame(stateTime), 50, 50);
    batch.end();
}

希望这会对您有所帮助。

一种运行动画的更有效，更简便的方法是使用TextureAtlas而不是Texture。这是使用TextureAtlas的示例：Libgdx Animation not working
