When I try to compile, the compiler will give me the error of “Cannot not implicitly convert type ‘UnityEngine.Camera[]’ to ‘UnityEngine.Camera’” for:
Camera camera = GetComponentsInChildren();
CameraRotation.cs and BallLauncher.cs are both attached to Player. And Main Camera is under Player. And I compared both of the scripts to this point and they are identical.
One other thing I noticed, is when I move Player around in the scene, the Main camera does not seem to move together with the player. So everytime I have to go back and make sure the camera is on the same position as the player.
