Merging Buildings

[santicpp]

I'm creating a td where you can merge a tower when you have at least two of the same kind.

I have this trigger:

• UpgradeWhiteT1
  • Events
    • Unit - A unit Starts the effect of an ability
  • Conditions
  • Actions
    • Set VariableSet TempGroup = (Units owned by (Triggering player) matching ((Unit-type of (Matching unit)) Equal to [Tier 1] White Tower).)
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • (Number of units in TempGroup) Greater than or equal to 2
      • Then - Actions
        • Unit Group - Remove (Triggering unit) from TempGroup.
        • Unit - Remove (Random unit from TempGroup) from the game
        • Unit - Replace (Triggering unit) with a [Tier 1] White Tower using The old unit's relative life and mana
      • Else - Actions
    • Custom script: call DestroyGroup(udg_TempGroup)

The trigger is working almost perfect, but: when i have more than 1 tower in my selection it doesnt work properly.
For example:
If i have 7 towers in my selection, the trigger replaces 4 of them instead of 3.
I tried to add a for each selected unit but its not working.

Immediate issue:
There is no Triggering player associated with the event you are using.
There is a Triggering Unit and you can refer to the Owner of Triggering Unit.

As for you problem:
Maybe you can find a way to label 2 towers as a pair. Do something when a Tower is finished being constructed to label it. Maybe set a custom value to all but 1 tower when there is an uneven number.
