Re: [Isugamedev-midworld] collision detection

[Kevin M. <ke...@vr...>]

looks like a smart final design.  what about your prototype design?  the
one that doesn't take a long time to write?  This looks like a final
design, and for the prototype you probably don't want to spend all your
time implementing collision.

I would just do the brute force method first, super easy, and you don't
have to worry about complex logic throwing you off the "get the prototype
done" path.
