Re: [Isugamedev-midworld] collision detection

[Ben S. <bs...@vr...>]

The idea behind the design was to make it flexible enough to support an
easy iterative development schedule. So brute force could be easily
written initially and better methods could be added from there. I'll see
if I can improve the document to reflect this.
