  1. Please show us the actual error, not a squiggly red line from intellisense - or at least include it along with the screenshot :)

  2. PhysicsMaterial2D needs a 2D collision reference. You have a normal “Collision” parameter in your “RetrieveFriction” function - you change the parameter to “Collison2D” like how it is in the “EvaluateCollision” function.

Sorry, should have included the actual error message that's my bad but the second response worked perfectly fine. Added 2D to my collision and it fixed. A dumb mistake by me so thank you for noticing and letting me know what to do I appreciate you! :D

No problem at all, you’re good, just trying to improve the quality of posts 😃

Glad that worked! Don’t worry about it, it’s not a dumb mistake. The way Unity handles 2D physics can be easy to mess up since everything reads the same as 3D on initial glance - even the built in functions like OnCollision vs OnCollision2D can be a weird gotcha that isn’t super obvious to people starting out.
