Question about Jass

Newhydra	How would I modify call forLoopBJ(function my_func) if I needed to pass my_func an integer(or any other variable)?

08-18-2003, 04:08 PM	#2
MarSara	Code: local integer i local integer j set i = 0 set j = 10 loop exitwhen i > j // do whatever endloop

08-18-2003, 04:18 PM	#3
PitzerMike	and of course: set i = i + 1 at the end of the loop

Newhydra	No, that's not what I meant...Here's another example: call ForGroupBJ( GetUnitsInRangeOfLocAll(150.00, PolarProjectionBJ(unitLoc), ( 150.00 * I2R(i) ), attackAngle)), function Trig_Do_Damage_Func004Func001A ) Now, Trig_Do_Damage_Func004Func001A needs to take a unit as a parameter, how do I modify this so I can pass it a unit?

ahh that problem, if you are willing to use global variables just do that, otherwise here's the trigger for a Unit-Group:

Code:

function Trig_Untitled_Trigger_001_Actions takes nothing returns nothing
    local integer iA
    local integer jA
    local integer iB
    local integer jB
    local unit random_unit
    local unit array unit_list
    local boolean already_picked

    set iA = 1
    set jA = CountUnitsInGroup(GetUnitsInRectAll(GetPlayableMapRect()))
    loop
        exitwhen iA > jA
        set random_unit = GroupPickRandomUnit(GetUnitsInRectAll(GetPlayableMapRect()))
        set already_picked = false
        set iB = 1
        set jB = iA
        loop
            exitwhen iB > jB
            if ( unit_list[iB] == random_unit ) then
                set already_picked = true
            endif
            set iB = iB + 1
        endloop
        if ( already_picked == false ) then
            set unit_list[iA] = random_unit
            set iA = iA + 1
        endif
    endloop


    set iA = 1
    loop
        exitwhen iA > iJ
        // Do Picked Unit actions here
        // Except use unit_list[iA] where you use GetEnumUnit()
    set iA = iA +1
    endloop
endfunction

just make sure to change GetPlayableMapRect() to the region.

EDIT: fixed a typo

Newhydra	ugh...there isn't a way to make a variable global to the trigger or something? (I can't use globals because this trigger is going to be called alot and the risk of them getting confused...)

MarSara	No, you can use globals, or if you need to use locals, just use my trigger.
