Question

我正在开发一个使用andengine的游戏，其中我使用Generic Pool来获取不同的精灵现在我的游戏类似于水果忍者，其中水果弹出屏幕，但在一段时间或15分钟后，游戏变得缓慢，因为我正在使用

  TargetPool tPool;
  tPool = new TargetsPool(apple,watermelon,lemon,mango,tomato);
  target=tPool.onAllocatePoolItem();
  tPool.onHandleRecycleItem(target);

 public class TargetsPool extends GenericPool<Sprite> {

private ITextureRegion mTextureRegion, mTextureRegion1,mTextureRegion2, mTextureRegion3,mTextureRegion4;

public TargetsPool(ITextureRegion pTextureRegion1,ITextureRegion pTextureRegion2,ITextureRegion pTextureRegion3,ITextureRegion pTextureRegion4,ITextureRegion pTextureRegion5) {
    if (pTextureRegion1 == null&&pTextureRegion2 == null) {

        throw new IllegalArgumentException(
                "The texture region must not be NULL");
    }
    mTextureRegion = pTextureRegion1;
    mTextureRegion1 = pTextureRegion2;
    mTextureRegion2 = pTextureRegion3;
    mTextureRegion3 = pTextureRegion4;
    mTextureRegion4 = pTextureRegion5;

}

@Override
protected Sprite onAllocatePoolItem() {
    Random r = new Random();
    int a =r.nextInt(5);
    //Log.e(Integer.toString(a),"a" );
    Sprite sprite;
    VertexBufferObjectManager getvertex = null;

    switch(a){
        case 0:
            sprite =new Sprite(0, 0, mTextureRegion,getvertex);
        break;
        case 1:
            sprite =new Sprite(0, 0, mTextureRegion1,getvertex);
            break;
        case 2:
            sprite =new Sprite(0, 0, mTextureRegion2,getvertex);
            break;
        case 3:
            sprite =new Sprite(0, 0, mTextureRegion3,getvertex);
            break;
        case 4:
            sprite =new Sprite(0, 0, mTextureRegion4,getvertex);
            break;
            default:sprite =new Sprite(0, 0, mTextureRegion,getvertex);
    }


    return sprite;
}

protected void onHandleRecycleItem(final Sprite target) {
    target.clearEntityModifiers();
    target.clearUpdateHandlers();
    target.setVisible(false);
    target.detachSelf();
    target.reset();

}

 }

我想知道如何从游泳池再次回收目标物品，就好像我每次游戏变慢都会产生新目标

Answer 1

这不是您从GenericPool访问项目的方式。不要自己致电onAllocatePoolItem()或onHandleRecycleItem ...您分别致电obtainPoolIem()和recyclePoolItem()以使用泳池功能。您应该阅读source code。

如何从之前生成的池中回收项目
