I was working on a map which needed a Dark Templar to have special abilities. I didn't want to have an area on the top of the map to activate the abilites so i tried to make a system where the ability "button" would follow a unit.
I finally got it.
You have a burrowed unit "off-centered" on the dark templar. When you unburrow the unit, the ability activates. In this test map there are 2 abilites: red and blue.
If you unburrow the red ability a red explosion happens. If you unburrow the blue ability a blue explosion happens.
The abilities are not thought out yet but this could be a good system for RPG's.
This can be modified to make all the burrowed units stacked so it doesn't take up as much room, but both ways are good.
