Help with a trigger

[SutinG]

Hi, I need to make a trigger that do something like this but I don't know how...

Unit Group - Pick every unit in (Units owned by (Triggering player) of type SomeUnit) and do (Actions)
Loop - Actions
Set TempPoint1 = (Position of (Picked unit))

// But if there is no picked unit, then...
// Do something
// else...
// Do something

IF units in Unit Group = 0 (Integer Comparison)

The actual line looks like this:

• If (All Conditions are True) then do (Then Actions) else do (Else Actions)
  • If - Conditions
    • (Number of units in TempGroup) Equal to 0
  • Then - Actions
  • Else - Actions

Or am I missing something?

EDIT:

Wait a sec, how can you find the position of a unit if there is no unit?
If there are no units in the group, it will merely run 0 times.

You could check if the Picked Unit is Equal to No Unit, using this line:

• (Picked unit) Equal to No unit

But that's fairly unusable.

If you could explain what you are trying to do, then perhaps I could help better.
