Question

我最近开始使用Andengine。我在教程视频的帮助下编写了这段代码。我想设置背景颜色并在场景中添加一个球（top.png）。当我运行程序黑屏时，模拟器抛出错误后不久我遇到了以下错误：

UpdateThread interrupted. Don't worry - this EngineDestroyedException is most likely expected!
org.andengine.engine.Engine$EngineDestroyedException
at org.andengine.engine.Engine.throwOnDestroyed(Engine.java:574)
at org.andengine.engine.Engine.onTickUpdate(Engine.java:560)
at org.andengine.engine.Engine$UpdateThread.run(Engine.java:820)

and my code:

   package com.example.oyundeneme2;

   import org.andengine.engine.camera.Camera;
   import org.andengine.engine.options.EngineOptions;
   import org.andengine.engine.options.ScreenOrientation;
   import org.andengine.engine.options.resolutionpolicy.RatioResolutionPolicy;
   import org.andengine.entity.scene.Scene;
   import org.andengine.entity.scene.background.Background;
   import org.andengine.entity.util.FPSLogger;
   import org.andengine.opengl.texture.TextureOptions;
   import org.andengine.opengl.texture.atlas.bitmap.BitmapTextureAtlas;
   import org.andengine.opengl.texture.atlas.bitmap.BitmapTextureAtlasTextureRegionFactory;
   import org.andengine.opengl.texture.region.TextureRegion;
   import org.andengine.opengl.texture.region.TiledTextureRegion;
   import org.andengine.ui.activity.BaseGameActivity;

   import android.view.Display;

   public class OyunEkrani1 extends BaseGameActivity{


    private static final int CAMERA_WIDTH=800;
    private static final int CAMERA_HEIGHT=480;

    private Camera myCamera;

    private BitmapTextureAtlas myBackgroundTextureAtlas;
    private TextureRegion myBackgroundTextureRegion;

    //private Engine myEngine;
    private Scene myScene;

    private TiledTextureRegion myCircleFaceTextureRegion;

    @Override
    public EngineOptions onCreateEngineOptions() {

    this.myCamera=new Camera(0, 0, CAMERA_WIDTH, CAMERA_HEIGHT);

    final Display myDisplay=getWindowManager().getDefaultDisplay();



    EngineOptions FixedStepEngine=new EngineOptions(true,
    ScreenOrientation.LANDSCAPE_FIXED, 
    new RatioResolutionPolicy(CAMERA_WIDTH, CAMERA_HEIGHT), myCamera);


        return FixedStepEngine;
    }



    @Override
    public void onCreateResources(
            OnCreateResourcesCallback pOnCreateResourcesCallback)
            throws Exception {


    BitmapTextureAtlasTextureRegionFactory.setAssetBasePath("gfx/");
    this.myBackgroundTextureAtlas=
    new BitmapTextureAtlas(null,1024,512,TextureOptions.BILINEAR_PREMULTIPLYALPHA);
    this.myCircleFaceTextureRegion =BitmapTextureAtlasTextureRegionFactory.createTiledFrom
    Asset(this.myBackgroundTextureAtlas, this, "top.png", 60, 60, 0, 0); // 64x32

    this.mEngine.getTextureManager().loadTexture(this.myBackgroundTextureAtlas);


    }

    @Override
    public void onCreateScene(OnCreateSceneCallback pOnCreateSceneCallback)
            throws Exception {
        mEngine.registerUpdateHandler(new FPSLogger());

        myScene = new Scene();
        myScene.setBackground(new Background(0.59804f, 0.5274f, 0.5784f));
    }

    @Override
    public void onPopulateScene(Scene pScene,
            OnPopulateSceneCallback pOnPopulateSceneCallback) throws Exception {
        // TODO Auto-generated method stub

    }

}

在“onCreateScene”中返回你的场景。试试这个

UpdateThread中断了。别担心 - 这种EngineDestroyedException很可能是预期的
