Jass Help

The Elite	Hi, Im trying to make a function that instead of having to use a player group to kill multiple units i can just type one line of code. eg. JASS: call KillUnits(udg_Thrall, a, b, udg_Jike) but i can figure out how to do it. To be more specific i cant figure out how to do anything. By the way i'm a complete noob at jass and this is just for education and maybe will use it. Thanks in advance

Vexorian	I don't understand, why di you have to use a player group to kill multiple units?

It can't be done in the way you want it (if I understand you), because functions in jass have a fixed number of arguments, there aren't optional arguments or something, so the only way you can do this is to write the function for any needed number of arguments.
e.g.:

Hidden information:

So there isn't really an advantage to:

JASS:

call KillUnit(udg_Thrall)
call KillUnit(a)
call KillUnit(b)
call KillUnit(udg_Jike)

(And you also don't need a unit group to do it this way)

You could do this:

JASS:

struct UnitCollection
    unit array units[50]
    integer amount

    static method Kill takes nothing returns nothing
        local integer i = 0
        loop
            exitwhen i == this.amount
            etcetc kill unit this.units[i]
            set i = i + 1
        endloop
    enmethod
endstruct

function SpellThatKillsUnits takes something returns something
    local UnitCollection uc = UnitCollection.create()
    local integer amount = 3                //The amount of units you're gonna kill in this spell

    ...

    set uc.units[0] = Unit 1 //wherever you get it.
    set uc.units[1] = Unit 2 //wherever you get it.
    set uc.units[2] = Unit 3 //wherever you get it.
    set uc.amount = 3        //3 units!
    call uc.Kill()
endfunction

And you would have a completely useless home-made unit group!

Pyrogasm	You could also do it by making a function that takes 5 unit arguments but passing some of them as null if you didn't need to kill 5 units but 3.
