PickRandomUnit

02-14-2007, 11:19 PM

Hi all, for one of my spells I need to pick a random unit from units in a fixed range. What is the best way to do this?
I used:

JASS:

call GroupEnumUnitsInRangeCounted( g, x, y, range, Condition( function Spell_Group_Conditions ), 1 )

but, for some reason, it doesn't work (it picks ALL the units in range), why?

I also tried to use:

JASS:

call GroupEnumUnitsInRange( g, x, y, range, Condition( function Spell_Group_Conditions ) )
set u = FirstOfGroup( g )

But the unit is not chosen random, it's always the same. Any Help? Thanks.

Pyrogasm	Do this: JASS: call GroupEnumUnitsInRange( g, x, y, range, Condition( function Spell_Group_Conditions ) ) set u = GroupPickRandomUnit(g) //... That should work for you.

Yes, I saw that BJ function when I was making some GUI tests, is it the only way to get a random unit from a group? Thanks BTW.

Rising_Dusk	Nah, but it's the easiest. If you do it without the BJ, you need to monitor the % chance, reduce with each passing unit in the group, etc. The BJ was made to make life easier, and it does. :P Just use the BJ, it's not like it leaks.

StockBreak	Ok, so I think I will use that function; but why GroupEnumUnitsInRangeCounted doesn't work? Thanks!

Some BJ's are utter crap though, like the BJFunctions which do the exact same thing as the functions they call
