Some notes on how to fix a NullReferenceException error in Unity3D

• Identify why it is null
• Fix that.

Expect to see this error a LOT. It’s easily the most common thing to do when working. Learn how to fix it rapidly. It’s easy. See the above link for more tips.

This is the kind of mindset and thinking process you need to bring to this problem:

Why do my Music ignore the Sliders ?

Step by step, break it down, find the problem.

what did you do in SC_CameraCollision script line 27?

Vector3 dirTmp = parentTransform.TransformPoint(defaultPos) - referenceTransform.position;

@votlesword

Vector3 dirTmp = parentTransform.TransformPoint(defaultPos) - referenceTransform.position;

read everything from the post above!

Vector3 dirTmp = parentTransform.TransformPoint(defaultPos) - referenceTransform.position;

in this line involved 2 Objects one is parentTransform and another one is referenceTransform

use debug.Log and find out which one is null.
