在 AndEngine 中创建我的第一个应用程序时，我只得到一个黑屏，而不是得到背景图像和播放按钮。 这里的代码 主要 Activity
public class MainActivity extends BaseGameActivity {
private BoundCamera camera;
private float WIDTH = 800;
private float HEIGHT = 480;
@Override
public Engine onCreateEngine(EngineOptions engineOptions){
return new LimitedFPSEngine(engineOptions,60);
}
@Override
public EngineOptions onCreateEngineOptions() {
camera = new BoundCamera(0,0,WIDTH,HEIGHT);
EngineOptions engineOptions = new
EngineOptions(true, ScreenOrientation.LANDSCAPE_FIXED, new FillResolutionPolicy(),camera);
engineOptions.getAudioOptions().setNeedsMusic(true).setNeedsSound(true);
return engineOptions;
}
@Override
public void onCreateResources(OnCreateResourcesCallback pOnCreateResourcesCallback) throws IOException {
}
@Override
public void onCreateScene(OnCreateSceneCallback pOnCreateSceneCallback) throws IOException {
}
@Override
public void onPopulateScene(Scene pScene, OnPopulateSceneCallback pOnPopulateSceneCallback) throws IOException {
}
}
BaseScene.java
public abstract class BaseScene extends Scene {
protected Engine engine;
protected Activity activity;
protected ResourceManager resourceManager;
protected VertexBufferObjectManager vbom;
protected Camera camera;
public BaseScene(){
this.resourceManager = ResourceManager.getInstance();
this.activity = resourceManager.activity;
this.engine = resourceManager.engine;
this.vbom = resourceManager.vbom;
this.camera = resourceManager.camera;
createScene();
}
public abstract void createScene();
public abstract void onBackKeyPressed();
public abstract SceneManager.SceneType getSceneType();
public abstract void disposeScene();
}
场景管理器.java
public class SceneManager {
private BaseScene mainMenu;
private BaseScene gameScene;
private BaseScene currentScene;
private static final SceneManager INSTANCE = new SceneManager();
private SceneType currentSceneType = SceneType.SCENE_MENU;
private Engine engine = ResourceManager.getInstance().engine;
public enum SceneType
{
SCENE_MENU,
SCENE_GAME
}
public void setScene(BaseScene scene){
engine.setScene(scene);
currentScene = scene;
currentSceneType = scene.getSceneType();
}
public static SceneManager getInstance(){
return INSTANCE;
}
public SceneType getSceneType(){
return currentSceneType;
}
}
我还有 2 个类 MainMenu 和 ResourceManager 我哪里出错了？
最佳答案
您至少应该在游戏 Activity 中从父类(super class)中实现 4 个回调方法。
onCreateEngineOptions:您应该在其中指定游戏引擎的主要特征。 (例如相机、渲染选项、声音选项)onCreateResources:您应该在其中加载游戏启动后需要立即使用的纹理和声音。onCreateScene:您应在其中实例化游戏的第一个场景。每当用户启动您的游戏时，引擎都会显示该游戏。onPopulateScene:实现此回调是可选的，取决于您的设计架构。但是，您应该调用给定的回调让引擎继续。
在这些方法中，您获得了一个pOnCreateSceneCallback 对象。完成该方法后，应调用该对象。您必须这样做，否则您的引擎会卡住，无法加载您的游戏。
