C# 统一2D。不同类型的敌人==对他们造成不同类型的伤害？

我正在制作2D平台，我需要帮助。我没有使用任何统一框架来制作我的游戏，我想了解统一的简单选项

从本质上说。我制造了一个击昏我的玩家的敌人，它冲到我身上并处理dmg（还没有，我还没有玩家的健康系统）。但我也制作了一个骷髅敌人，它有动画，而且是用剑攻击的

我想让骷髅从我的玩家那里获得伤害。我为他做了和普雷维乌斯一样的事，但是我得到了一个例外。。。这让我想到了敌人的剧本，而不是骷髅。我必须说我对此感到非常困惑

下面我将粘贴一个异常和脚本

NullReferenceException:对象引用未设置为对象的实例
DamageDeal.DealDmg（）（位于Assets/Scripts/DamageDeal.cs:37）
CombatBehavior.fixeUpdate（）（位于Assets/Scripts/CombatBehavior.cs:92）

如果（health我认为从Physics2D.overlappCircleall返回的所有碰撞R2D都将附加SkeletonScript的假设是有缺陷的

Collider2D[] skeletonToDamage = Physics2D.OverlapCircleAll(attackPos1.position,attackRange, whatIsEnemy);
        for (int i = 0; i < skeletonToDamage.Length; i++)
        {
            SkeletonScript skeletonScript = skeletonToDamage[i].GetComponent<SkeletonScript>();

collectedr2d[]skeletonodaign=Physics2D.overlappicrcleall（攻击位置1.位置、攻击范围、敌方）；
对于（int i=0；i

最好先获取碰撞R2D组件所连接的父游戏对象，然后再确定该游戏对象是否连接了“SkeletonScript”组件。
我是Unity和编程的初学者，如果我误解了您的意思，请原谅。我想到了这样的事情：对不起，我尝试了一些不同的组合，但是不起作用-请提供任何建议？学习是乐趣的一半。请尝试“代码var gameObject=skeletonodiage[i]。gameObject；var skeletonScript=gameObject.GetComponent（）；if（skeletonScript！=null）{//PUT LOGIC HERE}“从那个gameObject检查它是否有SkeletonScript组件。祝你好运！谢谢你的建议@Andrew McCallum。我没有得到这个-很可能我对所有这些东西都太陌生了。很抱歉发布了太长的帖子和愚蠢的问题^^^。好吧，我已经找到了如何将损坏放在应该放在的位置上的方法……我已经使用了gameObject.SendMessageColisionEnter2D。我希望这将适合我的项目的其余部分。再次感谢：D。
