I'm wondering how sphere calculates "distance." I am working on a system for a turn based tactical strategy game within UO and need an accurate way of handling distance. As is is now, I have had situations where I took exactly eight steps from the target and yet DISTANCE=11 or 4 steps and DISTANCE=6. Any suggestions?

Thanks, for the explanation. If anyone wants a little script to find the "simple distance" (the minimum number of steps to reach the target), here's a script:

[Function simpledist]
local.xdif=<eval SQRT(<eval <eval <p.x>-<src.p.x>> * <eval <p.x>-<src.p.x>>>)>
local.ydif=<eval SQRT(<eval <eval <p.y>-<src.p.y>> * <eval <p.y>-<src.p.y>>>)>
IF (<local.xdif> > <local.ydif>
return <eval <local.xdif>>
ELSE
return <eval <local.ydif>>
ENDIF
