Limit one structure type per region?

[cstorm]

In my map I have region in which you have to build a "Square Holder" to take control of that region. But I dont want people to be able to build another in the region inless the first is destroyed. I dont know how to set up triggers to prevent people from just building another "Square Holder" until the first is destroyed.
Note: there are 25 of these regions

Well, I am not sure whether you need 25 triggers on not, but I'd do that:

Region 1:

event;Unit enters region
condition;region1
action;set sqhol1 = 1
action; if/then/else
condition; if sqhol1 equals 1 equal to true
then; order building unit to stop
else; do nothing

You got my idea or need trigger?

uhhh trigger would be nicer and easier to follow lol

• Region 1
  • Events
    • Unit - A unit Begins construction
  • Conditions
    • (Unit-type of (Triggering unit)) Equal to Square Holder
    • ((Region1) contains (Triggering unit)) Equal to True
  • Actions
    • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
      • If - Conditions
        • (Number of units in (Units in (Region1) matching ((Unit-type of (Matching unit)) Equal to Square Holder))) Equal to 2
      • Then - Actions
        • Unit - Remove (Triggering unit) from the game
        • Game - Display to (Player group((Owner of (Triggering unit)))) the text: You can build only one Square Holder per region.
      • Else - Actions
        • Do nothing

All I do I probably do in a quite a long way, but that is just a way I find it easier. I'd just do myself 25 triggers, but there's probably an easier way tho.

what FannyShaver said would work.

but i still think this line is unnecessary:

• Do nothing

um couldnt u just make and set region arrays?
would make it ALOT easier imo.

 

[FannyShaver]

I've said that is my way, and my way involves lots of triggers, still - more triggers makes easier to control and edit for me personally. And yes, do nothing isn't necessary, but takes no problems involved having it as well.

Holder
    Events
        Unit - A unit Begins construction
    Conditions
        (Unit-type of (Constructing structure)) Equal to Farm
    Actions
        Set TempPoint = (Position of (Constructing structure))
        For each (Integer A) from 1 to NbOfHolderRegions, do (Actions)
            Loop - Actions
                If (All Conditions are True) then do (Then Actions) else do (Else Actions)
                    If - Conditions
                        (HolderRegion[(Integer A)] contains TempPoint) Equal to True
                    Then - Actions
                        Set TempUnitGroup = (Units in HolderRegion[(Integer A)] matching ((Unit-type of (Matching unit)) Equal to Farm))
                        If (All Conditions are True) then do (Then Actions) else do (Else Actions)
                            If - Conditions
                                (Number of units in TempUnitGroup) Greater than or equal to 2
                            Then - Actions
                                Unit - Remove (Constructing structure) from the game
                            Else - Actions
                        Custom script:   call DestroyGroup(udg_TempUnitGroup)
                    Else - Actions
        Custom script:   call RemoveLocation(udg_TempPoint)

Something like this should do the trick. Replace Farm with your building. Add all regions you want to check for to the HolderRegion array. Replace NbOfHolderRegions with the number of regions you're checking for.
