Detecting Collision with a Character Collider

So, I'm trying to find a way to make it so when my player hits a wall it takes damage. I already have the damage system set up(I tested it ) but now I was trying to make a collision method that would deal damage to the player with only having a Character Controller and not a box collider on it. I thought it would be simple and I could just put a Box Collider on the player, but I assume because of my movement system or something the floor sort of collapses.

TL;DR: What I need is a way that I can have just a Character Controller on my player, and execute off of a collision to another object. Thanks!

 

Hello. You have a collider on your player - a capsule collider. What do you want more so as to detect contact ?

 

When I use OnCollisionEnter() it doesn’t work

 

Can you show us your function OnCollisionEnter() please? Maybe you forgot something. I would like to be sure that we are talking about the same thing. Have you tested code with some Debug.Log() steps - always a good start so as to know where code goes wrong ++
