我正在 libgdx 中制作游戏.我使用 AssetManager 类来加载资产.当我开始我的游戏时，它需要更多的时间来加载 android 设备上的资源并在那时显示黑屏.我该如何解决这个问题.

I am making a game in libgdx. I use AssetManager class to load assets. When I start my game its takes more time to load assets on android device and show black screen at that time.How can I resolve that problem.

推荐答案

它会显示一个空白屏幕.为了解决这个问题，您可以在加载资源时渲染一些东西，并在加载完成后切换到菜单屏幕.

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

}


 }

一个重要的事情是它仍然会为那些你想在加载过程中渲染的精灵显示一个空白屏幕，以尝试只渲染很少的东西并且根本没有声音.

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.
