Question

我有一个我正在处理的相机脚本，我根本无法让相机平底锅工作。它识别输入，但它根本不移动相机。

它在某一点工作，但它在变焦或旋转时重置相机，现在变焦和旋转工作完美。此问题是由于您可以在底部找到的函数PositionRotation。

问题出在您的更新功能中。它一直调用CameraZoom，因为你设置了

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

CameraZoom调用PositionRotation，您可以将摄像机的位置重置为原始位置。

尝试将其设置为

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

这应该可以解决问题。
