如何在 cocos2d android 中与其他对象碰撞时删除对象（精灵）？

Question

为了学习 cocos2d-android 游戏引擎，我开始使用本教程开发游戏，http://dan.clarke.name/2011/05/how-to-make-a-simple-android-game-with-cocos2d-pt2-%E2%80%93-rotating-turrets/ 并添加了 3 艘船以使其更具吸引力并固定在其上的大炮，如果火球从船上掉下，船将通过保持这个概念作为编码的概念而被烧毁和摧毁，但是当火球落在船上时它不会被摧毁（删除），我尝试了很多方法但无法得到解决方案有人能说出为什么船没有被摧毁请？ 这是我的编码。

public void update(float dt)
{
    LinkedList<CCSprite> projectilesToDelete = new LinkedList<CCSprite>();

    for (CCSprite projectile : _projectiles)
    {
        CGRect projectileRect = CGRect.make(projectile.getPosition().x - (projectile.getContentSize().width / 2.0f),
                                            projectile.getPosition().y - (projectile.getContentSize().height / 2.0f),
                                            projectile.getContentSize().width,
                                            projectile.getContentSize().height);




        LinkedList<CCSprite> targetsToDelete = new LinkedList<CCSprite>();

        for (CCSprite target : _targets)
        {
            CGRect targetRect = CGRect.make(target.getPosition().x - (target.getContentSize().width),
                                            target.getPosition().y - (target.getContentSize().height),
                                            target.getContentSize().width,
                                            target.getContentSize().height);

            if (CGRect.intersects(projectileRect, targetRect))
                targetsToDelete.add(target);
        }

        LinkedList<CCSprite> shipsToDelete = new LinkedList<CCSprite>();
        for (CCSprite ship : _ships)
         {
                CGRect shipRect = CGRect.make(ship.getPosition().x - (ship.getContentSize().width),
                                             ship.getPosition().y - (ship.getContentSize().height),
                                             ship.getContentSize().width,ship.getContentSize().height);


                for (CCSprite target : _targets)
                  {
                        CGRect targetRect = CGRect.make(target.getPosition().x - (target.getContentSize().width),
                                                                                  target.getPosition().y -
                                                                                (target.getContentSize().height),
                                                                target.getContentSize().width,target.getContentSize().height);


                     if (CGRect.intersects(targetRect, shipRect))
                        {
                                shipsToDelete.add(ship);
                                break;
                        }
                }                      
         }

        for (CCSprite target : targetsToDelete)
        {
            _targets.remove(target);
            removeChild(target, true);
        }

        if (targetsToDelete.size() > 0)
            projectilesToDelete.add(projectile);

        for (CCSprite ship : shipsToDelete)
        {
            _ships.remove(ship);
            removeChild(ship, true);
        }
    }

    for (CCSprite projectile : projectilesToDelete)
    {
        _projectiles.remove(projectile);
        removeChild(projectile, true);

        if (_shipDestroyed > 0)
        {
            _shipDestroyed = 0;
            CCDirector.sharedDirector().replaceScene(Gameoverlayer.scene("You Win!"));
        }
    }

}

像这样添加弹丸与船相交的代码

LinkedList<CCSprite> targetsToDelete = new LinkedList<CCSprite>();

for（CCSprite 目标：_targets） { CGRect targetRect = CGRect.make(target.getPosition().x - (target.getContentSize().width), target.getPosition().y - (target.getContentSize().height), target.getContentSize().width, target.getContentSize().height);

        System.out.println("projectiles to delete continue... : " + volume);


                LinkedList<CCSprite> shipsToDelete = new LinkedList<CCSprite>();




                {
                for (CCSprite ship : _ships)
                {
                        CGRect shipRect = CGRect.make(ship.getPosition().x - (ship.getContentSize().width/2),
                                ship.getPosition().y - (ship.getContentSize().height/2),
                                    ship.getContentSize().width,
                                ship.getContentSize().height);
                        System.out.println("ships to delete continue... : " + volume);
                              if (CGRect.intersects(targetRect, shipRect))
                                {

                                  System.out.println("ships intersected:)... : " + volume);
                                     shipsToDelete.add(ship);
                                }


                    if (targetsToDelete.size() > 0)
                        shipsToDelete.add(ship);
                }



    for (CCSprite ship : shipsToDelete)
    {
        _ships.remove(ship);
        removeChild(ship, true);

            CCDirector.sharedDirector().replaceScene(Gameoverlayer.scene("You Win!"));
        }
    }

}

并在 addsomeothercode() 方法中添加精灵，并通过给出代码为删除精灵

public void spriteMoveFinished(Object sender)
{
    CCSprite sprite = (CCSprite)sender;


    if (sprite.getTag() == 1)
    {  if (sprite.getTag() == 1)
        _ships.remove(sprite);
    }
