java - Android Studio LibGDX 游戏不显示障碍物和地板

Question

我正在尝试制作一款回避游戏，已完成 95%，但是，当我尝试添加无限障碍时，游戏从一开始就看起来像这样(没有错误):How the game looks

我不知道我做错了什么，有人可以帮助我吗？我将非常感激，因为这是我为让我的游戏正常运行而需要做的最后一件事。我的 GameScreen 中的代码:

    }

我的 MainGame 类中的代码:

    package com.circlecrashavoider;

    import com.badlogic.gdx.Game;
    import com.badlogic.gdx.assets.AssetManager;
    import com.badlogic.gdx.graphics.Texture;
    import com.circlecrashavoider.scene2d.Box2DScreen;
    import com.circlecrashavoider.scene2d.Scene2DScreen;

    public class MainGame extends Game {

        private AssetManager manager;

        public AssetManager getManager() {
            return manager;
        }

        @Override
        public void create() {
            manager = new AssetManager();
            manager.load("floor.png", Texture.class);
            manager.load("overfloor.png", Texture.class);
            manager.load("overfloor2.png", Texture.class);
            manager.load("obstacle.png", Texture.class);
            manager.load("obstacle2.png", Texture.class);
            manager.load("crash.png", Texture.class);
            manager.load("player.png", Texture.class);
            manager.finishLoading();

            setScreen(new GameScreen(this));
        }
    }
