Collision2D not triggering

Questions & Answers
1

I have those objects:

Ball - Rigid2Body, Gravity=0, Angular Drag=0, Has a Box Collider 2D with isTrigger=False

Floor - Rigid2Body, Gravity=0, Angular Drag=0, Has a Box Collider 2D with isTrigger=True

in the Floor script I have:

void onTriggerEnter2D(Collider2D target)
{
    print("SADSA");
}

when I set the velocity of the ball to overlap/hit the floor, the trigger never occurs…
I’ve tried unity 4.5f and even with Unity 4.6 Beta…

Any ideas?

You need a capital letter on OnTriggerEnter

void OnTriggerEnter2D(Collider2D target)
{
    print("SADSA");
}

If it isn’t that, tell me.
