我在将资产加载到Libgdx Java项目时出现问题，它运行了一段时间（没有资产，只是黑屏），然后程序关闭。当我评论行：“batch.draw（Assets.sprite_back，0,0）;”它运行正常，屏幕是白色的，它不会关闭。我不认为这是代码问题 - 我做的一切都和Youtube教程中显示的一样。

以下是代码：

public class GameScreen implements Screen {

    Test game;
    OrthographicCamera camera;
    SpriteBatch batch;

    public GameScreen(Test game){
        this.game=game;
        camera = new OrthographicCamera();
        camera.setToOrtho(true, 1920, 1080);. 
        batch = new SpriteBatch();

    }

    @Override
    public void render(float delta) {
        Gdx.gl.glClearColor(1F, 1F, 1F, 1F);
        Gdx.gl.glClear(GL30.GL_COLOR_BUFFER_BIT);
        camera.update();
        batch.setProjectionMatrix(camera.combined);
        batch.begin();
        batch.draw(Assets.sprite_back, 0, 0);
        batch.end();
    }


public class Assets {

    public static Texture texture_back;
    public static Sprite sprite_back;

    public static void load(){
        texture_back = new Texture(Gdx.files.internal("menu/back.png"));
        texture_back.setFilter(TextureFilter.Linear, TextureFilter.Linear);
        sprite_back = new Sprite(texture_back);
        sprite_back.flip(false, true);
    }
}

你的assset永远不会加载，sprite为null，你永远不会在你的代码中调用加载和accsedes尚未分配的精灵。

不是我喜欢这种做法，而是试试这个：

public GameScreen(Test game){
    this.game=game;
    camera = new OrthographicCamera();
    camera.setToOrtho(true, 1920, 1080);. 
    batch = new SpriteBatch();


Asset.load();


}

也许在你的方法秀中会更好。
