团结：产生敌人有效，但他们不可见

Question

我正忙于创建一个需要集成波浪生成器的学校项目。 目前，我以这个视频为例，并在我的项目中实现了它。https://www.youtube.com/watch?v=q0SBfDFn2Bs

一切都很好，我也得到了我的调试日志。主要问题是：我看不到我的敌人。 （不是约翰塞纳的家伙哈哈，在那种情况下这将是合乎逻辑的；））

我是 Unity 的新手，我喜欢它的界面和工作流程，但我还有很多东西要学。我希望有人可以帮助我！ :)

据我所知，您也在更改球棒的 Z 位置。一般来说，你不想在 2D 游戏中这样做，因为它可能会落后于那里发生的事情。在代码中，我确实注意到您正在使用世界上的随机点，因此您需要检查这些点的 Z 位置并将它们更改为 0 或 1。这是您需要在这些点上更改的 Image！希望这会有所帮助！
