Count units in region

[Devrak]

Hi. I am creating an AoE spell that deals 20*X damage where X is how many units there is in the region. I only have one problem, how would I count every unit in that region?

Thanks for any kind of reply!

Group the units in a unit group and count the number of units in that group (integer action).

Pick every unit and the region and set a integer variable +1 for every picked unit

Then you use it for the calculations

 

[Dinowc]

set Group = units in <region>
set UnitCount = number of units in Group
call DestroyGroup(udg_Group)
.....
cause <unit> to damage <unit> dealing 20 x UnitCount damage of type...

where:

Group is a unit group variable
and
UnitCount is a integer variable

EDIT: ups Larcenist already suggested that xd

Hmm, this is how I did it..

• AoE Ability
  • Events
    • Unit - A unit Begins casting an ability
  • Conditions
    • (Ability being cast) Equal to AoE Ability
  • Actions
    • Set AoE_Point = (Target point of ability being cast)
    • Unit Group - Pick every unit in (Units in (Region centered at AoE_Point with size (400.00, 400.00)) matching (((Owner of (Picked unit)) is an enemy of (Owner of (Casting unit))) Equal to True)) and do (Actions)
      • Loop - Actions
        • Unit Group - Add (Matching unit) to AoE_Group
    • Set Integer = (Number of units in AoE_Group)
    • Game - Display to (All players) the text: (String(Integer))
    • Unit Group - Pick every unit in AoE_Group and do (Actions)
      • Loop - Actions
        • Unit - Set life of (Picked unit) to ((Life of (Picked unit)) - (20.00 x (Real(Integer))))

However, the text only displays one or zero units and the units doesn't take any damage. What's wrong?
