Make building indestructible for one team only

[Unregistered]

Hello. I am new to mapmaking and can’t figure out how to do this seemingly simple thing (I am using Roc Editor):

I want to make it so that a building can only be destroyed by one team and not the other. If the building is attacked, I can use the IS ATTACKED event, and then check the ATTACKING player in the conditions, and force him to stop if he is on the wrong team. This works fine if a player attacks the building with his normal attack, but if they use a spell, such as DND, they can still destroy the building and no events are triggered. I tried using the TAKES DAMAGE event, but I can’t find any counterpart of this to use for the conditions.

Can anyone help?

Sorry for the late responses everyone, exams are coming up and I'm completely buggered already

This is actually a fairly difficult thing to do properly, but there are a few ways to go about doing it that will come close to what you ideally want.

Perhaps the easiest way is to set up triggers with the following:

[b]trigger 1:[/b]
[okay here's the setup - you should know already what player numbers are on 
what team, because you should have specified this in scenario -> force properties. 
With this in mind, you can do the following]

[make 2 variables of type player group, one called "team1" and another called "team2"]

event:
  map initialisation
conditions:
  none
actions:
  wait 1 seconds
[player group - add player]
  add (player x) to (team1 or team2)
[you need to do the above action for all players, and add them into "team1" or "team2" 
depending on what team they are in in the force properties]

[b]trigger 2:[/b]

event :
  a unit is issued an order targeting a point
condition: [unit comparison]
  (target of issued order) equal to <the building in question>
[boolean comparison - player in player group]
  (owner of <ordered unit>) in (team1) <= use team 1 or team 2, depending on 
what team you don't want to attack the building
action: [issue order with no target]
  order (ordered unit) to (stop)

This way is probably the easiest and best, because you can catch cases where units are
attacking AND where units are casting spells on the building.

If you want to, you could be extra mean and add in this extra action:

[unit - set life to value]
set life of (ordered unit) to [<life of (ordered unit) - 50>]

this way, every time a unit goes to attack the building, they will lose 50 hit points of life.
