Unit Group and periodic tiggers

[hdm]

How should I use the unit group to not damage the targets more than once in periodic triggers ? I mean, the units must be on any group and them changed to other when they're damaged or they shouldn't be in any group and them I add them to one when they are damaged ?

How the trigger should look like ? If you can do it by [triggers] [/triger] would be awesome.

• Actions
  • Player Group - Pick every player in (All players) and do (Actions)
    • Loop - Actions
      • If (All Conditions are True) then do (Then Actions) else do (Else Actions)
        • If - Conditions
          • (Targeted_Unit is in Your_Unit_Group[(Player number of (Picked player))]) Equal to False
        • Then - Actions
          • Unit - Cause Your_Unit to damage Targeted_Unit, dealing x damage of attack type Spells and damage type Normal
          • Unit Group - Add Your_Unit to Your_Unit_Group[(Player number of (Picked player))]
        • Else - Actions
          • Do nothing

This is what I am using, you just need to clear that unit group when you turn off that trigger.

I hope it helps.

P.S. If you want a unit from a unit group to do the damage just use this:

• Unit Group - Pick every unit in Your_Unit_Group and do (Actions)
  • Loop - Actions
    • -The Function from above-

Usually we use one of 2 popular methods: either we add already affected targets into specific global group that is taken into account when filtering targets, or we flag those using (global boolean array) - again, this flag is taken into consideration when finding new targets.
