我正在开发一款安卓游戏。我想显示包含一些图像的界面。我在资产中有一个名为 gfx 的文件夹。这个文件夹包含图像。我已经写了这段代码。
公共类 MainActivity 扩展 SimpleBaseGameActivity {
private static int CAMERA_WIDTH = 800;
private static int CAMERA_HEIGHT = 480;
private ITextureRegion mBackgroundTextureRegion, mTowerTextureRegion, mRing1, mRing2, mRing3;
private Sprite mTower1, mTower2, mTower3;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
@Override
public EngineOptions onCreateEngineOptions() {
// TODO Auto-generated method stub
final Camera camera = new Camera(0,0,CAMERA_WIDTH,CAMERA_HEIGHT);
return new EngineOptions(true,ScreenOrientation.LANDSCAPE_FIXED,new RatioResolutionPolicy(CAMERA_WIDTH, CAMERA_HEIGHT), camera);
//return null;
}
@Override
protected void onCreateResources() {
// TODO Auto-generated method stub
try {
// 1 - Set up bitmap textures
ITexture backgroundTexture = new BitmapTexture(this.getTextureManager(), new IInputStreamOpener() {
@Override
public InputStream open() throws IOException {
return getAssets().open("gfx/background.png");
}
});
ITexture towerTexture = new BitmapTexture(this.getTextureManager(), new IInputStreamOpener() {
@Override
public InputStream open() throws IOException {
return getAssets().open("gfx/tower.png");
}
});
ITexture ring1 = new BitmapTexture(this.getTextureManager(), new IInputStreamOpener() {
@Override
public InputStream open() throws IOException {
return getAssets().open("gfx/ring1.png");
}
});
ITexture ring2 = new BitmapTexture(this.getTextureManager(), new IInputStreamOpener() {
@Override
public InputStream open() throws IOException {
return getAssets().open("gfx/ring2.png");
}
});
ITexture ring3 = new BitmapTexture(this.getTextureManager(), new IInputStreamOpener() {
@Override
public InputStream open() throws IOException {
return getAssets().open("gfx/ring3.png");
}
});
// 2 - Load bitmap textures into VRAM
backgroundTexture.load();
towerTexture.load();
ring1.load();
ring2.load();
ring3.load();
// 3 - Set up texture regions
this.mBackgroundTextureRegion = TextureRegionFactory.extractFromTexture(backgroundTexture);
this.mTowerTextureRegion = TextureRegionFactory.extractFromTexture(towerTexture);
this.mRing1 = TextureRegionFactory.extractFromTexture(ring1);
this.mRing2 = TextureRegionFactory.extractFromTexture(ring2);
this.mRing3 = TextureRegionFactory.extractFromTexture(ring3);
} catch (IOException e) {
Debug.e(e);
}
}
@Override
protected Scene onCreateScene() {
// TODO Auto-generated method stub
final Scene scene = new Scene();
Sprite backgroundSprite = new Sprite(0, 0, this.mBackgroundTextureRegion, getVertexBufferObjectManager());
scene.attachChild(backgroundSprite);
// 2 - Add the towers
mTower1 = new Sprite(192, 63, this.mTowerTextureRegion, getVertexBufferObjectManager());
mTower2 = new Sprite(400, 63, this.mTowerTextureRegion, getVertexBufferObjectManager());
mTower3 = new Sprite(604, 63, this.mTowerTextureRegion, getVertexBufferObjectManager());
scene.attachChild(mTower1);
scene.attachChild(mTower2);
scene.attachChild(mTower3);
return scene;
}
}
但只能在用 xml 编写的屏幕上显示 hello world。我注意到没有调用 onCreateResources() 和 onCreateScene() 。需要显式调用它们吗？
谁能帮我？？
提前致谢。
