1:04:01Q: Correct me if I'm wrong, but it seems early on we started with a bottom-centre position for collision detection on our hero. We moved to a centre position which was offset in both X and Y. Now it seems we use a centre X and Y and are continuing to compute the bottom-centre position. Do you feel this needs to be consolidated in any way?
