Allow players to walk through one another but maintain normal physics with the rest of the world

Hello world,

In my game, I have numerous player objects with collider2ds and rigidbody2ds attached. I would like to allow the players to walk through one another while maintaining normal physics behaviour with the rest of the world. However, I would also like to be able to receive calls to OnCollisionEnter2D and OnTriggerEnter2D, so in essence, I want to be in complete control of the collisions between two objects on the same layer while maintaining normal behaviour with the rest of the word.

I have tried various solutions involving the global physics collision matrix but in every attempt, I was unable to receive calls to the respective collision callbacks. Anyone have any bright ideas?

Hmm.. Until Unity updates with the Physics2D.IgnoreCollision , for now you can add an extra trigger (soft) collider, slightly wider than your non-trigger (hard) collider. And when Player2 enters Player1's soft collider, disable the Player2's hard one until it exits Player1's soft one. It might cause a few problems depending on your game but that's a temporary solution.
