Reading and Generating QR codes with C# in Unity 3D — the easy way
Adrian M. Nenu

Hello Adrian!
I was using your script to decode and worked perfectly. However an error occurs whenever I decode something and try to change to a scene which contains OnGUI stuff like labels, scrollviews… 
The error (Cannot get pixels when webcam is not running
UnityEngine.WebCamTexture:GetPixels32()) happens when I try to press play again.

Are you familiar with this?
This looks like a bug to me, although I’m new to unity!

Thanks for everything!
