Detecting Collision for DanmakU?

Unity Engine
1

Hi,

I’m using the DanmakU Package from GitHub - james7132/DanmakU: An open source Danmaku development kit for Unity3D. .
It’s pretty good, but I have no idea how to set up collision.

I added a User Layer called Bullet and have this attached to the player

void OnCollisionEnter2D(Collision2D col)
    {
      
        if (col.gameObject.layer == 12)
        {
             Debug.Log("I'VE BEEN HIT UGHHH");
        }
}

… but it’s not working.
I attached an img of the Physics layers.

Is there maybe a problem with the way I set up the Physics Layers Collision?

I think the emitter is spawning Danmaku Prefabs so I attacked a Circle Collider but nothing’s happening.

Any help greatly appreciated! Thank you.

Maybe that you’re using the LayerCollisionMatrix for 3D physics not 2D physics? The image you show above is from the 3D physics settings.

I’ve never used the LayerCollisionMatrix before. Don’t quite understasnd why its only for 3D. Any resources you recommend? (https://docs.unity3d.com/Manual/LayerBasedCollision.html)

If the matrix is for collision between two objects and their layers why is it for 3D?

Thank you.

The one you show in your image is for 3D because you went into the Project Settings and selected Physics. If you look, there are separate project settings for Physics 2D next to it in the list. Use those settings there.
