平移不能在我的相机脚本内工作

我有一个摄像头脚本，我正在努力，我只是无法让相机平底锅工作。它识别输入，但它根本不移动相机。平移不能在我的相机脚本内工作

它在一个点上工作，但它在缩放或旋转时重置相机，现在变焦和旋转工作完美。这个问题是由于功能PositionRotation，你可以在底部找到。

问题出在你的更新函数中。它调用CameraZoom所有的时间，因为你设置

Input.GetAxis("Mouse ScrollWheel") <= 0

而且CameraZoom调用PositionRotation，在那里你相机的当前位置恢复到原来的位置。

尝试将其设置为

if (Input.GetAxis("Mouse ScrollWheel") <= -0.1) 
{ 
    CameraZoom(); 
} 
if (Input.GetAxis("Mouse ScrollWheel") >= 0.1) 
{ 
    CameraZoom(); 
}

这应该做的伎俩。
