我的RTS游戏存在问题，我的敌人单位不会攻击我在关卡开始后创建的任何基础建筑物。他们去攻击当等级开始时那里的所有其他建筑物，但没有建造的那些。
有一个列表被设置为最接近单位的目标，他们将攻击他们最近的目标，但任何新实例化的建筑物或单位都不会因某种原因受到攻击。
当WorldObject脚本没有做任何事情时，会在WorldObject脚本中的所有单元上调用DecideWhatToDo（）函数。然后它从WorkManager脚本调用FindNearbyObjects（）。
在新的单位和建筑物被创建之前，一切都在进行，以前是否有人遇到过这种问题？

答案 0 :(得分：0)
您需要检查的第一件事是内部
FindNearbyObjects()
变量
hitColliders = Physics.OverlapSphere(position, range);
实例化新建筑物时更改其大小。如果不是这种情况，可能是因为您在实例化时没有向建筑物添加碰撞器。
但是，我认为有更好的方法可以在不使用此物理的情况下检测建筑物.OverlapSphere（），其性能可能很昂贵。如果我是你，我将给建筑物（原始的和实例化的）提供一个特殊的标签，我将在我的逻辑中使用它来检测它们。因此，它们将成为您方法的潜在目标：
