这是我的 OOP 设置：
MainGame 类扩展了 Game：
...
public void create () {
assets = new Assets(); // my custom Assets object (constructor creates manager and AssetDescriptors
assets.load(); // loads Asset Descriptors into manager
assets.getManager().finishLoading();
batch = new SpriteBatch();
setScreen(new PlayScreen(this, assets));
}
...
public void dispose () {
assets.dispose(); // disposes asset manager
super.dispose();
batch.dispose();
}
PlayScreen 类实现 Screen：
public PlayScreen(MainGame game, Assets assets) {
this.assets = assets;
this.game = game;
background = assets.getManager().get(assets.getBackground());
hero = new HeroSprite(290, 1100, this, assets);
// Create Game camera and Hub also
}
public void render(float delta) {
// Clear screen
// Use game batch to draw to screen
}
public void dispose() {
assets.dispose();
}
类英雄精灵：
public HeroSprite(int x, int y, PlayScreen screen, Assets assets){
this.assets = assets;
this.screen = screen;
// Animation Textures
heroWalking = assets.getManager().get(assets.getWalking()); // This is an Asset Descriptor
walkAnime = new Animation(heroWalking) // my own custom animation class which takes the spritesheet and returns the appropriate frames
...
}
// This does not contain a dispose method
抱歉，如果那里有很多代码，我会尽量减少。我的主要问题是我是否正确处理？
看起来不错，我的游戏运行良好。但是当我退出游戏并重新进入时显示黑屏。这在桌面和 Android 上都会发生。
一个可行的解决方案是使用 Super Cleaner App 清除 Android 上的内存。由于这是一个内存问题，我认为这与我处理不当有关。

public class Assets {
private AssetManager manager;
private AssetDescriptor<Texture> background;
private AssetDescriptor<Texture> wood;
public AssetManager getManager() {
return manager;
}
public AssetDescriptor<Texture> getBackground() {
return background;
}
public AssetDescriptor<Texture> getWood() {
return hero;
}
public Assets(){
manager = new AssetManager();
background = new AssetDescriptor<Texture>("textures/static/bg.png", Texture.class);
hero = new AssetDescriptor<Texture>("textures/static/hero.png", Texture.class);
...
}
public void load(){
manager.load(background);
manager.load(hero);
...
}
public void dispose(){
manager.dispose();
}
}
