IsUnitInRange what is it precicely

[kokon]

IsUnitInRange is it difference from unit center to unit center or is it distance from one unit collision circle edge to another? Or what is it?

for example this func gives me 158

function DistanceBetweenUnits takes unit u, unit v returns real
local real dx = GetUnitX(u) - GetUnitX(v)
local real dy = GetUnitY(u) - GetUnitY(v)
return SquareRoot(dx * dx + dy * dy)
endfunction

and is unit is range giving is me yes for 120 for some reason

Distance between points does not take collision into account - it just takes units' x and y coordinates.
IsUnitInRange checks distance between two units including their collisions.

 

[kokon]

so
GroupEnumUnitsInRange

also considers collison size?.. Thats cool

 

[Nichilus]

No, it does not. IsUnitInRange is not the same as GroupEnumUnitsInRange.

GroupEnumUnitsInRange

so this one relies on unit center points?

 

[Nichilus]

Yes, it just compares origin points of units, collision is ignored.
