cocos2d-x怎么删除滚出屏幕的精灵

就是想把说有超出屏幕的精灵全部删掉。。。。

Answer 1

void youclass::deleteSprite()
{
for (int i = 0 ; i < spriteArray->count() ; i ++)
{
CCSprite * spr = (CCSprite *)spriteArray->objectatIndex(i);
if (spr->getPositionX() < 0)//这里只判断了一边，如果需要可以判断四条边
{
deleteArray->addObject(spr);
}
}
for (int i = 0 ; i < deleteArray->count() ; i ++)
{
CCSprite * spr = (CCSprite *)deleteArray->objectatIndex(i);
spr->removeFromParentAndCleanup( true );
spriteArray->removeObject( spr );
}
deleteArray->removeAllObjects();
}
在update函数里面调用。spriteArray，deleteArray为保存精灵的容器，2.X版本用CCArray
