UnassignedReferenceException: The variable camTransform of CameraControl2 has not been assigned.
You probably need to assign the camTransform variable of the CameraControl2 script in the inspector.

The error message actually tells you exactly what your error is - your camTransform variable has not been linked to anything. Wherever you have this script attached, if you select it in the hierarchy, you’ll see in the inspector the variables associated with it. One of them is “camTransform”. You need to drag your main camera onto this. Or, if this script is on your camera, then you should set this variable in Awake or Start, like so:

camTransform = transform;

I’ve already assigned it in the inspector, but it still isn’t working

If you are getting the same error, but you dragged and dropped something into the camTransform slot in the inspector, then it’s possible you have multiple copies of the script in your scene, so check for that.
