Question

我有一个射击游戏，你在相反方向射击两颗子弹，所以如果敌人接近子弹的起点（敌人在子弹起点区域内），则会发生错误，

这是我的代码：

if((_target.collidesWith(bullet))){

                    resourcesManager.enemyPool.recyclePoolItem(_target);
                    targets.remove();
                    score=score+1;

                }
                if((_target.collidesWith(bullet2))){
                    resourcesManager.enemyPool.recyclePoolItem(_target);
                    targets.remove();
                    score=score+1;
                    break;
                }

错误日志：

我遇到了同样的问题，没有回答你的问题让我发现了我的问题。

实际上，您在此处同时删除了您的recyclePoolItem，因为在一个帧中，您删除了同一对象的两次（当您的_target与两个对象发生碰撞时发生）。要纠正这个问题，只需用＆＃34;编写代码，否则如果＆＃34;而不只是＆＃34;如果＆＃34;在＆＃34; if＆＃34;语句：

if((_target.collidesWith(bullet))){
    resourcesManager.enemyPool.recyclePoolItem(_target);
    targets.remove();
    score=score+1;
} else if((_target.collidesWith(bullet2))){
    resourcesManager.enemyPool.recyclePoolItem(_target);
    targets.remove();
    score=score+1;
}
