Re: [Algorithms] Knowing when I'm at the end of a path

[Jason Z. <zi...@op...>]

Thanks for all the great responses to this question.  I didn't expect the
deluge of suggestions.  :)

I like the idea of checking the delta distance each frame, and if its larger
you have passed the waypoint.  This works really well with our current
system since we are getting the distance anyway, and would be easy to debug.

I was hoping for a more "perfect" solution, though.  If the character starts
off facing the wrong direction and has to loop around it looks like every
suggestion here would need special code to detect this and start checking
only after the character is facing the right direction.  I guess this is why
we went with a simple distance in the first place, its the only method we
could think of that didn't need coding for that case.  But of course its
better to be less zen and more robust, especially with critical
pathfollowing like we are doing.

Thanks again,
