[JASS] Detecting train units queue

[Storyyeller]

Is there any way to determine if a building is currently training a unit or has units queued?

I tried the whole EVENT_PLAYER_UNIT_BEGIN/CANCEL/FINISH thing
but it didn't work because a CANCEL even is generated whenever you cancel a unit, even if there are others in the queue.

Any ideas?

GetUnitCurrentOrder ?

or idk maybe there isn't an order for training units :E

Why not store the amount of units being trained, so when you cancel you can lower the number by 1, so if it's still above 1 the building is training more units.

Because it doesn't tell you when a unit is queued, only when the actual training begins.

So if the player, say queued 7 units, the count would still be at 1. Then he if canceled all of them, the count would be at -6. See the problem?

I managed to solve it using a combination of orders and normal events
I'll post my code here in case anyone else has the same problem.

    // in main
    set TrigTrainOrder=CreateTrigger()
    call TriggerRegisterAnyUnitEventBJ(TrigTrainOrder, EVENT_PLAYER_UNIT_ISSUED_ORDER) 
    call TriggerAddAction(TrigTrainOrder,function FuncTrainOrder)
    set TrigTrainDone=CreateTrigger()
    call TriggerRegisterAnyUnitEventBJ(TrigTrainDone, EVENT_PLAYER_UNIT_TRAIN_CANCEL) 
    call TriggerRegisterAnyUnitEventBJ(TrigTrainDone, EVENT_PLAYER_UNIT_TRAIN_FINISH) 
    call TriggerAddAction(TrigTrainDone,function FuncTrainDone)

function FuncTrainOrder takes nothing returns nothing
    local integer p = GetPlayerId(GetOwningPlayer(GetTriggerUnit()))
    local integer t = GetUnitTypeId(GetTriggerUnit())
    local string s = UnitId2String(GetIssuedOrderId())
    
    if s==null then   //UnitId2String returns null if the given order was not a unit training order
        return
    endif

    if t=='h000' or t=='h01S' or t=='h02Z' or t=='h03Q' then  //check whether triggering unit was a capital
        set capitalunitqueue = capitalunitqueue + 1   //increment unit training count
        if capitalunitqueue == 1 then //if the count is greater then 1, it was already removed
            call removeFromGroup(GetTriggerUnit(), p, 0)
        endif
    endif
endfunction

function FuncTrainDone takes nothing returns nothing
    local integer p = GetPlayerId(GetOwningPlayer(GetTriggerUnit()))
    local integer t = GetUnitTypeId(GetTriggerUnit())

    if t=='h000' or t=='h01S' or t=='h02Z' or t=='h03Q' then  //check whether triggering unit was a capital
        set capitalunitqueue = capitalunitqueue - 1   //decrement unit training count
        if capitalunitqueue <= 0 then //if the count is greater 0, add it back to the group
            call add2group(GetTriggerUnit(), p, 0)
        endif
    endif
endfunction

Use jass tag in the future.

I used JASS tags before, but brackets don't show up correctly inside them, so I changed them to code tags.
