give unit-type ability with an upgrade?

[radeonmaster]

Generally, here's what I want to do: I want a unit-type to be granted an ability when a particular upgrade is researched.

In my map, I have a custom attachment ability that equips grunts with shields, but I only want it to be applied after the user researches the "Equip Shields" upgrade.

Is this possible? Thanks.

The second trigger is initially off.

• Untitled Trigger 095
  • Events
    • Unit - A unit Finishes research
  • Conditions
    • (Researched tech-type) Equal to Defend
  • Actions
    • Game - Display to (All players) the text: True
    • Set Temp_Group_1 = (Units owned by (Owner of (Triggering unit)) of type Footman)
    • Unit Group - Pick every unit in Temp_Group_1 and do (Actions)
      • Loop - Actions
        • Unit - Add Defend to (Picked unit)
    • Custom script: call DestroyGroup(udg_Temp_Group_1)
    • Trigger - Turn on Untitled Trigger 096 <gen>

• Untitled Trigger 096
  • Events
    • Unit - A unit enters (Playable map area)
  • Conditions
    • (Unit-type of (Triggering unit)) Equal to Footman
    • (Current research level of Defend for (Owner of (Triggering unit))) Greater than 0
  • Actions
    • Unit - Add Defend to (Triggering unit)

Another way is to create a whole new unit and apply the "berserk upgrade" effect. This method would allow you to modify the unit even more without using triggers.

add ability in object editor to your unit
make ability require - your upgrade

or
