SImple question needing simple answer

What action to order training unit to stop training?Coz order triggering unit to stop won't work.

• Untitled Trigger 002 Copy
  • Events
    • Unit - A unit Begins training a unit
  • Conditions
    • (Unit-type of (Trained unit)) Equal to Farmer
  • Actions
    • Set Temp_Group = (Random 1 units from P1man)
    • Unit Group - Pick every unit in Temp_Group and do (Actions)
      • Loop - Actions
        • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
          • If - Conditions
            • (Number of units in Temp_Group) Equal to 0
          • Then - Actions
            • Unit - Order (Triggering unit) to Stop
          • Else - Actions

What's that "Pick every unit" action supposed to do?
The group will never be 0 because of the trained unit and the training unit itself, therefore not passing the condition and order to stop.

 

[pangahas]

Unit enters playable map
unit type of entering unit=man
add entering unit to P1man
P1man=units owned by player of type man
Temp_group=random 1 unit from P1
Pick every unit in temp group,if there's no unit man orders the training unit to stop..

Ah now I get it.
You can order the unit to Cancel.

call IssueImmediateOrderById( GetTriggerUnit( ), 851976 )
call IssueImmediateOrderById( GetTriggerUnit( ), 0xD0008 )

This will force the building to hit Cancel the moment it starts training a unit.

But note, that if a played trains the same unit in a row meaning the unit training query, it won't work.

Edit:

This worked for me

function CancelTrain_Actions takes nothing returns nothing
    local group g = GetUnitsOfTypeIdAll( 'hfoo' )
    local unit temp
    local integer unitCount = 0
    local integer cancel = 0
    loop
        set temp = FirstOfGroup( g )
        exitwhen temp == null or unitCount >= 1
        set unitCount = unitCount + 1
        call GroupRemoveUnit( g, temp )
    endloop
    call DestroyGroup( g )
    set g = null
    if unitCount > 0 then
        loop
            exitwhen cancel >= 7
            call IssueImmediateOrderById( GetTriggerUnit( ), 851976 )
            set cancel = cancel + 1
        endloop
    endif
endfunction

//===========================================================================
function InitTrig_CancelTrain takes nothing returns nothing
    local trigger CancelTrain = CreateTrigger(  )
    call TriggerRegisterAnyUnitEventBJ( CancelTrain, EVENT_PLAYER_UNIT_TRAIN_START )
    call TriggerRegisterAnyUnitEventBJ( CancelTrain, EVENT_PLAYER_UNIT_TRAIN_FINISH )
    call TriggerAddAction( CancelTrain, function CancelTrain_Actions )
    set CancelTrain = null
endfunction

So.I just have to add those 2 custom scripts?

 

[DragoonZombie]

Either of them, they do the same.

• CancelTrain
  • Events
    • Unit - A unit Begins training a unit
  • Conditions
  • Actions
    • Set tempGroup = (Random 1 units from (Units owned by Player 1 (Red) of type Footman))
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • (Number of units in tempGroup) Equal to 0
      • Then - Actions
        • Custom script: call IssueImmediateOrderById( GetTriggerUnit( ), 851976 )
      • Else - Actions
    • Custom script: call DestroyGroup( udg_tempGroup )

 

[pangahas]

It doesn't work..

 

[DragoonZombie]

Like? U know that it prevents training if there are no units of the specific type on the map.

 

[pangahas]

It still continues training..even if no. of units in temp group is 0

 

[DragoonZombie]

That must be some problem on your end. Because it works just fine for me.

 

[pangahas]

It works now but would that script also work if for example I set conditions on what unit type of the trained unit is?

 

[DragoonZombie]

No, this only works if the building can only train that specific unit.
What you can do though is set the Requirement for the unit to be his own type.
It will have the same effect.
