Collision with no contact?

I just received an OnCollisionEnter(), but the Collision’s contacts array has a length of zero. Is this… normal? Up until now I’ve always used contacts[0] without checking, and I haven’t seen any code sample check either.

So, what’s up with this empty contacts array? And should I always check its length before using contacts[0] ?

Same issue here

can’t find solution…

You should create your array like so:

var contacts = new ContactPoint2D[] {new ContactPoint2D()};

Hope this helps to feature trouble makers.
