What does this tigger do

[emil23]

hi i found in my map jass tigger im just wondering if it can be repsonsible for crash i totaly dont know jass tigger si only know gui this jass looks like this
function CreateUnitsInRectRandom takes player id, integer unitid, rect whichRect, integer number returns nothing
local integer i = 0
loop
exitwhen i == number
call CreateUnit(id, unitid,GetRandomReal(GetRectMinX(whichRect), GetRectMaxX(whichRect)), GetRandomReal(GetRectMinY(whichRect), GetRectMaxY(whichRect)), GetRandomDirectionDeg())
set i = i + 1
endloop
endfunction

shouldi remove this? what does it do can it be responsible for eror

It chooses a random point in a region and creates the unit there, this happens 'number' times

Well, just declaring that function won't do any harm. However, it depends on how it's being used in your triggers. It could possibly freeze your game if you do something like this

call CreateUnitsInRectRandom(Player(0), 'hpea', bj_mapInitialPlayableArea, -1)

That -1 parameter would lead to an infinite loop, because that function doesn't take negative numbers into consideration.[/code]
