Unselectable footmen and their behaviour.

[EMance]

I'm attempting to make a sort of DotA clone, and want the footmen in one team to use defend once they hit 1/3hp or less, dropping it again once they hit 4/5hp or more.
No matter what I try, it can't be done. Does anyone else know what to do here?

First off, defend is toggleable ability - so what do you want to do? If he uses Defend at 33% health, then defend will be still active even when he reaches 20% health.

If that Footman has Locust ability, you cannot pick him up via Pick every unit in region/range; you can try to "pick every unit owned by player matching condition" as that may work.
Or you should make a trigger

• Untitled Trigger 002
  • Events
    • Unit - A unit enters (Playable map area)
  • Conditions
    • (Unit-type of (Triggering unit)) Equal to Footman
  • Actions
    • Unit Group - Add (Triggering unit) to YourGroup

This picks all footman once they are created and adds them to YourGroup. Then you can just pick every unit in YourGroup and order actions you want.

or you can do this:

• Untitled Trigger 002
  • Events
    • Unit - A unit enters (Playable map area)
  • Conditions
    • (Unit-type of (Triggering unit)) Equal to Footman
  • Actions
    • Trigger - Add to Active Defend <gen> the event (Unit - (Triggering unit)'s life becomes Less than or equal to (0.33 x (Max life of (Triggering unit))))

and

• Activate Defend
  • Events
  • Conditions
  • Actions
    • Unit - Order (Triggering unit) to Human Footman - Defend

The first trigger will make that new footman trigger the second trigger - so whenever his life becomes 33% of his max health, he will activate defend.
