constant native GetTrainedUnit takes nothing returns unit

Needs to be in response to the event - Unit trains a unit

Do you refer to a building cast a spell?
Or create a unit at the point of construction?

i have this so far but for some reason it doesnt add the unit to the group

function Trig_Battlegrounds_setting_Groups_Actions takes nothing returns nothing
    local unit u
    set u = GetTrainedUnit()
    call GroupAddUnit( Battlegrounds_Group_Player[0], u )
    
endfunction

//===========================================================================
function InitTrig_Battlegrounds_setting_Groups takes nothing returns nothing
    set gg_trg_Battlegrounds_setting_Groups = CreateTrigger(  )
    call TriggerRegisterUnitEvent( gg_trg_Battlegrounds_setting_Groups, gg_unit_u00J_0085, EVENT_UNIT_TRAIN_FINISH )
    call TriggerAddAction( gg_trg_Battlegrounds_setting_Groups, function Trig_Battlegrounds_setting_Groups_Actions )
endfunction

and its for like when barracks creates a unit

If your Unit Group is an array type, it would return as null, you need to actually call a function to create that Unit Group first, before do something to it (Add/Remove).

For example;
set udg_UnitGroup[0] = CreateGroup()

Then only, you can access that Unit Group.

it is created in the trigger tht declares it as a global

edit: lol i found out the problem i accidently set the units being trained in the unit editor to units sold instead of units trained lol oops thx for ur help tho

In the post #4, I don't see any CreateGroup() function there ?
As I said before, if it is a Unit Group variable with ARRAY enabled, you must create it first by using the function CreateGroup() before accessing it.

You can't simply have globals to a Unit Group ARRAY, if it is non-array, well you can leave it as it is.

But we're talking about ARRAY Unit Group, that is why that function is needed.
