自上而下的射手子弹根本不准确

Question

我检查了Youtube，Google和以前的答案，但无法让我的游戏向鼠标射击。玩家旋转以跟随鼠标，当他射击时，它要么不准确，要么有时会向另一个方向射击。我真的不想发送大量代码，但觉得因为我混合了来自不同教程的代码，尽管我有点组织它，但最好让你看到它，所以很抱歉，提前感谢

Answer 1

如果你的玩家正在看鼠标，而你正试图在那里射击，这似乎有点复杂......

实例

化项目符号后，您只需要执行两件事： 立即旋转它，使其面向与玩家相同的方向。 （这可以通过 transform.rotation= playerobject.rotation） 施加向前的力。 （由于物体朝向玩家面对的位置，因此当您"发射"弹丸时瞄准，因此您无需瞄准，只需将其向前移动即可）

transform.forward将在这里工作。
