Java Libgdx-加载资产

我在将一个资产加载到libgdxjava项目时遇到了一个问题，它运行了一段时间（没有资产，只是黑屏），然后程序就关闭了。当我注释行：“batch.draw（Assets.sprite_back，0，0）；”时，它正常运行，屏幕是白色的，并且没有关闭。我不认为这是代码的问题——我做的一切都是一样的，就像Youtube教程上显示的那样

代码如下：

LwjglGraphics: created OpenGL 3.2+ core profile context. This is experimental!

您的assset从未加载，sprite为空，您从未调用代码来加载和访问尚未分配的sprite

并不是说我喜欢这样做，而是尝试一下：

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);
    }
}

也许在你的方法展示中会更好。

确保LwjglApplicationConfiguration#useGL30设置为false。该文件中的代码都是这些吗？当您实现屏幕时，还应该有一个实现的方法来显示初始化纹理的位置。

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


Asset.load();


}
