Question by cerzDdDd · Oct 07, 2021 at 10:08 PM · collisioncollision detectioncollision event

OnColliderEnter2D not working

Hi, I have a problem with OnCollisionEnter2D, the function is never called, despite the objects all have boxCollider2D and rigidbody2D, I also checked that the kinematic type was disabled. Where else am I wrong? I trust in your help

The most probable issue is how you move your objects. can you add your code regarding this to your question? also do you have any layers set? did you change the collision matrix?

Can you send your code? It's almost impossible to help if you don't. It's just good practice. I have my suspicions, but I can't know anything until I see your code.

Since you barely provided any information, I'll put a few possibilities in here. 1. One of your objects isn't marked as trigger. 2. You aren't using Collision2D as the argument. 3. Which are you using? OnColliderEnter2D or OnCollisionEnter2D? You listed both of them. The correct one is OnCollisionEnter2D.

If any of these helped, please mark this answer as the correct one.

I will also request that you add a little more information when asking a question next time, however.

On top of @Coleclaw199 's answer, also check whether you should really use OnCollisionEnter2D or OnTriggerEnter2D (if your colliders have "IsTrigger" set to true)
