; that obvious, so a little explanation is in order. This
; parameter is used to determine if the pathfinder has gotten close
; enough to the center of a given path square to warrant looking up
; the next step on the path.
;
; This is needed because the speed of certain sprites can
; make reaching the exact center of a path square impossible.
; In Demo #2, the chaser has a velocity of 3 pixels per frame. Our
; tile size is 50 pixels, so the center of a tile will be at location
; 25, 75, 125, etc. Some of these are not evenly divisible by 3, so
; our pathfinder has to know how close is close enough to the center.
; It calculates this by seeing if the pathfinder is less than
; pixelsPerFrame # of pixels from the center of the square.
; This could conceivably cause problems if you have a *really* fast
; sprite and/or really small tiles, in which case you may need to
; adjust the formula a bit. But this should almost never be a problem
; for games with standard sized tiles and normal speeds. Our smiley
; in Demo #4 moves at a pretty fast clip and it isn't even close
; to being a problem.
