推荐答案

它将显示一个空白屏幕. 为了解决此问题，您可以在完成资产加载时渲染某些内容，并在完成加载后切换到菜单屏幕.

Well it will show a blank screen. In order to solve this problem you can render something while loading of assets is done and as the loading is done you switch to menu screen.

import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.assets.AssetManager;
import com.badlogic.gdx.graphics.GL10;
import com.badlogic.gdx.graphics.GLCommon;
import com.badlogic.gdx.graphics.OrthographicCamera;
import com.badlogic.gdx.graphics.Texture;
import com.badlogic.gdx.graphics.g2d.SpriteBatch;
import com.badlogic.gdx.graphics.g2d.TextureAtlas;
import com.shooter.waste.of.a.game.Assets;
import com.shooter.waste.of.a.game.utils.Game;
import com.shooter.waste.of.a.game.utils.Screen;

public  class LoadingScreen extends Screen{


public AssetManager manager;
SpriteBatch batcher;
Game game;
OrthographicCamera cam;
TextureAtlas load;
float stateTime;
AtlasSprite bg;
public LoadingScreen(Game game,SpriteBatch batcher) {
    super(game);
    this.batcher = batcher;
    this.game = game;
    manager = new AssetManager();
    manager.load("data/shoot",TextureAtlas.class);
    manager.load("data/b.jpg",Texture.class);

    cam = new OrthographicCamera(480, 800);
    cam.position.set(480 / 2, 800 / 2,0);
            load = new TextureAtlas("data/load");
            bg = new AtlasSprite(load.findRegion("loadingscrnbg"));




    }

    @Override
    public void render(float deltaTime)
    {
        update(deltaTime);
    GLCommon gl = Gdx.gl;
    gl.glClearColor(0, 0, 1f, 0.1f);
    gl.glClear(GL10.GL_COLOR_BUFFER_BIT);
    cam.update();
    batcher.setProjectionMatrix(cam.combined);
    batcher.begin();
            batcher.draw(bg, 0, 0);

    batcher.enableBlending();
    batcher.end();



}

@Override
public void pause() {
    // TODO Auto-generated method stub

}

@Override
public void resume() {
    // TODO Auto-generated method stub

}

@Override
public void dispose() {
    // TODO Auto-generated method stub

}

@Override
public void update(float deltaTime) 
{
    if(manager.update())  \\ gives true when all assets are loaded
    {
        Assets.load(manager);
        game.setScreen(new GameScreen(game, batcher));
    }
}

@Override
public void backKeyPressed() {
    // TODO Auto-generated method stub

}


 }

重要的一点是，对于您要在加载过程中渲染的精灵，它仍将显示空白屏幕，以尝试仅渲染很少的东西而根本不发出声音.

One important thing is that it will still show a blank screen for those sprites which u want to render during the loading to try to render only few things and no sounds at all.

希望这对您有所帮助.
