Infinite mass and moment solution

Postby theisegeberg » Thu Sep 27, 2012 3:41 am

Hi guys,

This is just a question. But sometimes I've heard the problem stated as: What happens if two objects of infinite mass collides. And really, from a pure physics point of view, it hasn't to do with static mass, it has to do with relative mass. If both have infinite mass, they might as well both have a mass of 1 each of them. Because it's the same.

I did a really quick fix for this to allow for infinite masses colliding, and it works logically and chipmunk handles it nicely.

Best,
Theis

What was the solution? I'd be curious to see. Seems like you'd need to insert a number of checks all over the source code for that to work.

In Chipmunk 6.1.1 collision between infinite mass objects are now ignored which also fixes the unsolvable constraint issue.
