好的，我是 javascript 和 Unity 的新手，所以这显然是一个非常菜鸟的初学者问题。基本上我已经创建了一个放在我的相机上的脚本。然后，当我在游戏中选择一个模型时，它成为相机脚本的目标，我试图让相机顺利转向它。下面是我正在尝试的

在更新功能中，我使用 raycast 在鼠标单击时捕捉一个单位。这成为脚本中的目标变量。它将 bool 设置为 true，然后在 moveto 函数中跟随目标。但如果我在设备上按住鼠标左键，它似乎只会移动相机。我试图选择一个单元，然后让相机平稳地旋转到该单元。关于这个菜鸟错误的任何想法？

答案来自我上面的评论：

“当我上我的开发机器时，我必须看看，但同时尝试用 Input.GetButtonDown("Fire1") 替换 Input.GetButton("Fire1")。就像一个测试，因为查看你的代码什么都没有跳出来。只要按住按钮，GetButton 就为真，过去我遇到过当鼠标移离对象时它错误触发的问题。
