    Hypothesisly, I got two 2d colliders named A and B,A is not a trigger but B is. So when the two collides which unity message will be triggered on A? OnTriggerEnter2D or OnCollisionEnter2D?

    For my test, I dont get anyone of them... The layer filter setting is OK. It is just a litte different that I used

    Code (CSharp):
    1.               if (damageEntities[args[1]].BoxCol2D != null)
    2.                     {
    3.                         damageEntities[args[1]].BoxCol2D.enabled = true;
    4.                     }
    5.                     if (damageEntities[args[1]].CircleCol2D != null)
    6.                     {
    7.                         damageEntities[args[1]].CircleCol2D.enabled = true;
    8.                     }
    for active the B collider which was inactive from beginning.

    PS: The A and B are overlapping in 2d space.

    If either is a trigger, only trigger callbacks happen but that's easier to test yourself than ask TBH. If you don't get this then it'll be something odd in your scripts/projects so you should experiment in an empty project before you address other issues in your project.

    Also, I have no idea what your code above is trying to show. Are you indicating that these things are inactive? They won't collide if they're inactive as they don't exist.
