I'm making a flight simulator and trying to make a chase cam with it. When I run the c# code it gives me this error --> NullReferenceException: Object reference not set to an instance of an object Plane.Pilot.Update () (at Assets/PlanePilot.cs:14) and the 14th line of code is Camera.main.transform.position = moveCamTo; how do I get rid of the error?

This means that you are assigning null to Camera.main.transform.position (it's trying to reference an object, but it can only reference to null, causing the exception).

You need to assign a value to the moveCamTo variable before assigning it to Camera.main.transform.position.

You can also test to make sure the variable isn't null before assigning it:

if (moveCamTo != null) {
//moveCamTo is not null - you can assign it
