Hi, i’m currently developping a game with unity3d (2019.3 version). My problem actualy, is that I don’t know how to make two colliders don’t collide with each other, but still be able to interact.

Okay, let’s get an example. Let’s say that I have a zombie and a player, I want the player going through the zombie, but i want the collider of the player able of being detected by the one on the zombie, so the the zombie can attack the player, same for the bullets that the player shoot on the player. (little precision, the zombie attack the player thanks to a trigger collider in front of him).

I’ve already tried to modify things in the layer collision matrix, but the player and zombie aren’t able to interact. So that’s not good.

So I came here to find a little bit of help :slight_smile: (ps : sorry for my bad english)

You may duplicate the collider as trigger. You could then have colliders not interacting but triggers raising OnTrigger messages.
