我最近开始学习 AndEngine,但我在运行它时遇到了麻烦。我正在学习有关基础知识的教程,我想加载一个png image
,但它给了我错误并且项目失败了。
这是源代码
public class MainActivity extends BaseGameActivity {
protected static final int WIDTH = 800;
public static final int HEIGHT = 460;
BitmapTextureAtlas playerTexture;
ITextureRegion playerTexureRegion;
Scene scene;
@Override
public EngineOptions onCreateEngineOptions() {
Camera mCamera = new Camera(0, 0, WIDTH, HEIGHT);
EngineOptions engine = new EngineOptions(true, ScreenOrientation.LANDSCAPE_FIXED, new RatioResolutionPolicy(WIDTH, HEIGHT), mCamera);
return engine;
// TODO Auto-generated method stub
}
@Override
public void onCreateResources(OnCreateResourcesCallback pOnCreateResourcesCallback) throws Exception {
// TODO Auto-generated method stub
loadsfx();
pOnCreateResourcesCallback.onCreateResourcesFinished();
}
private void loadsfx() {
// TODO Auto-generated method stub
BitmapTextureAtlasTextureRegionFactory.setAssetBasePath("assets/");
playerTexture = new BitmapTextureAtlas(getTextureManager(),64,64);
playerTexureRegion = BitmapTextureAtlasTextureRegionFactory.createFromAsset(playerTexture, this, "fred1.png",0,0);
playerTexture.load();
}
@Override
public void onCreateScene(OnCreateSceneCallback pOnCreateSceneCallback) throws Exception {
// TODO Auto-generated method stub
this.scene = new Scene();
this.scene.setBackground(new Background(0,125,58));
pOnCreateSceneCallback.onCreateSceneFinished(this.scene);
}
@Override
public Engine onCreateEngine(EngineOptions pEngineOptions) {
// TODO Auto-generated method stub
return super.onCreateEngine(pEngineOptions);
}
@Override
public void onPopulateScene(Scene pScene, OnPopulateSceneCallback pOnPopulateSceneCallback) throws Exception {
// TODO Auto-generated method stub
Sprite sPlayer = new Sprite(WIDTH / 2, HEIGHT / 2, playerTexureRegion, this.mEngine.getVertexBufferObjectManager());
sPlayer.setRotation(45.0f);
this.scene.attachChild(sPlayer);
pOnPopulateSceneCallback.onPopulateSceneFinished();
}
这就是 LogCat 所说的

请帮助我,我非常想了解引擎,但它不起作用。
