Joker	I'm trying to check if a unit is # units away from another unit. JASS: SquareRoot( (x2-x1)(x2-x1) + (y2-y1)(y2-y1) ) < 10 This is what I tried to use. Heres what I'm using to move a unit JASS: call SetUnitPosition( a, x1+5 Cos(f bj_DEGTORAD), y1+5 Sin(f bj_DEGTORAD) ) What are you supposed to do? Are they both bad? Alternatives?

HINDYhat	You should use this native instead : JASS: constant native IsUnitInRange takes unit whichUnit, unit otherUnit, real distance returns boolean As far as moving goes, I prefer using SetUnitX() and SetUnitY(), who are both faster than SetUnitPosition and with those, units retain their orders. The only problem with SetUnitX/Y is that the map crashes if a unit is moved too far out of map bounds.
