我需要知道如何解决这个问题,正如您所看到的那样,我的演员正在展示它的背后.

这是我的代码

   stage.addActor(option);    stage.addActor(store);    stage.addActor(custom);    stage.addActor(quit);}@OverrIDepublic voID show() {    Audio.playMusic(true);    batch = new SpriteBatch();    atlas = new TextureAtlas("data/mainmenu/mainmenu.pack");    skin = new Skin();    skin.addRegions(atlas);    backGround = atlas.findRegion("background");    backGround.getRegionHeight();    backGround.getRegionWIDth();}public voID drawBackGround() {    float w = 854;    float h = 480;    float y = 0;    float x = 0;    batch.draw(backGround, x, y, w, h);}@OverrIDepublic voID hIDe() {    dispose();}@OverrIDepublic voID pause() {}@OverrIDepublic voID resume() {}@OverrIDepublic voID dispose() {    batch.dispose();    skin.dispose();    atlas.dispose();    stage.dispose();}

}

我也注意到的是,如果我摆脱了

stage.draw();

图像出现.

解决方法:

从batch.begin()和batch.end()中取出stage.draw().舞台上确实有它自己的Spritebatch,所以您目前确实有一些同伴.我认为确实会造成麻烦.所以最好的方法是这样的：

@OverrIDe    public voID render(float delta) {        Gdx.gl.glClearcolor(0.09f, 0.28f, 0.2f, 1);        Gdx.gl.glClear(GL10.GL_color_BUFFER_BIT);        stage.act(delta);        stage.draw();        batch.begin();        drawBackGround();        batch.end();    }

我建议您将背景放到舞台上.图像也是一个Actor,因此您可以将其添加到舞台中,然后调用.toBack()(Back)将其置于背景中.
