Getting Pre-Placed Units

[Mr_Bean]

Hi guys,

This is probably something that I should know, but I don't
How can I get pre-placed units in vJASS? I have tried this:

scope TestSystem initializer OnInit

    private function OnInit takes nothing returns nothing
        local unit u = gg_unit_h001_0002
    endfunction

endscope

But it gives errors. I've also tried with a 0.0 timer, but with the same errors. The main error that I can't solve:
Undeclared variable: gg_unit_h001_0002
It happens in this function:

function CreateUnitsForPlayer0 takes nothing returns nothing
    local player p= Player(0)
    local unit u
    local integer unitID
    local trigger t
    local real life

    set gg_unit_H000_0001=CreateUnit(p, 'H000', - 205.2, - 560.6, 270.000)
    call SetHeroLevel(gg_unit_H000_0001, 10, false)
    call SetUnitState(gg_unit_H000_0001, UNIT_STATE_MANA, 690)
    set gg_unit_h001_0002=CreateUnit(p, 'h001', - 728.7, 532.3, 315.000)
    set u=CreateUnit(p, 'h002', - 861.7, 380.0, 270.000)
    set u=CreateUnit(p, 'h002', - 718.2, 364.7, 270.000)
    set u=CreateUnit(p, 'h002', - 611.2, 392.3, 315.000)
    set u=CreateUnit(p, 'h002', - 548.9, 473.5, 0.000)
    set u=CreateUnit(p, 'h002', - 547.4, 602.6, 0.000)
endfunction

Any help would be appreciated

Thanks,

Mr_Bean

Ive encountered that problem before, the global variable is only valid if referenced at least once from GUI(So if you do something like Set Position of Mountain King(0001) the global is created and then you can use it)

it sucks tho

 

[Mr_Bean]

Hmmm, thought that may be the case
So I would need to create the units with vJASS then? Sigh...

 

[edo494]

either, or make some simple trigger and try placing those preplaced units there(something like move unit instantly, that should allow usage of those vars, at least until next trigger save, I never tried after reopening the map)

if you are going to create those units with vJass tho, force compiler error(write a to somewhere) and copy content of CreateUnitsForPlayer function and place it to some init trigger, give them some variables or one big array of units, and you can reference those for further use

Why don't you create them yourself?

// System does this:
set gg_unit_h001_0002=CreateUnit(p, 'h001', - 728.7, 532.3, 315.000)

//So, do this:

call GroupEnumUnitsInRange(g, 1, -728.7, 532.3, null)

I think you got the arguments the wrong way around for the second statement.
Thanks, but I found a way around it. I created a temporary unit variable in the Variable Editor and then set it to each pre-placed unit. Then I can successfully access the globals, such as gg_unit_h001_0001.

The error (I think) came from the vJASS compiler. All vjass codes are moved at the top most of all the codes, so below it was Generated Globals of Warcraft 3

So the best suggestion is to create them by code.

u can always set the units at 0.00 time so it would give it time to create those units.
thats how i used to do it. since then i just switched over and created the units in the code as it was both easier and nicer looking.

It's not that serious of an issue. I just needed to access pre-placed units to test a system I'm making.
