Question

我通过Youtube，Google和以前的答案进行了检查，但无法使我的游戏朝着鼠标射击。玩家旋转以跟随鼠标，当他射击时，它要么不准确，要么有时朝另一个方向射击。我真的不想发送大量的代码，但是我觉得我混合了不同教程中的代码，尽管我有点组织起来，但最好还是让您看一下，所以对不起，先谢谢您

Answer 1

如果您的玩家正在看着鼠标，而您正试图在那儿射击，这似乎有点复杂...

实例化项目符号后，只需要做两件事：立即旋转它，使其面对与播放器相同的方向。（这可以通过transform.rotation = playerobject.rotation来完成）向前施加力量。（由于该物体面向您的玩家所面对的位置，因此在“发射”该弹丸时瞄准，因此您无需瞄准，只需将其沿前进轨迹发送即可）

transform.forward将在这里工作。

自上而下的射手子弹根本不准确
