ok, from what I heard (read actuaally), kao wants to give units turrets with triggers... like, making a corsair always be above a zealot so that the zealot can attack both ground and air.
to do that, you need to first create those two units, create 1 location in the size of your unit, not bigger or smaller, (use SF to perfect it) and make those triggers:
1. Hyper Troggers - make 4.
2. this:
Player:
Human player...
Example:
Player 1
Conditions:
player [human] Bring at least 1 [your hero] to anywhere
-OR-
player [human] commands at least 1 [your hero]
Example:
Player 1 brings at least 1 zealot to anywhere
Actions:
(I'll make it all in the Example format)
Center location labeled 'Hero' on Protoss Zealot owned by Player 1 at Anywhere.
Issue order to all Protoss Corsair owned by Player 2 at anywhere 'patrol' to 'Hero'.
Preserve Trigger.
3. this: (all goes in example now, but you get the point)
Players:
Player 1
Conditions:
Player 2 brings at most 0 (or 'exactly', but it's safer to use 'at most'... don't ask why) Protoss Corsair to 'Hero'.
Actions:
Move all Protoss Corsair owned by player 2 at anywhere to 'Hero'.
Preserve trigger.
4. this is a death trigger:
Players:
Player 1
Conditions:
Player 1 brings at most 0 Protoss Zealot to 'anywhere'.
Actions:
Kill all Protoss Corsair for player 2.
(Optional - put it if you make a respawn:) Preserve trigger.
5. make sure to give the corsair invinsibility and set his allience to enemy with the human's enemies and ally with the human's allies (and him).
also, if you make a respawn, use the 'Create unit with properties' and make the corsair invinsible, or use the 'Set invincibility' action - but that your trigger is 1 action longer.
also, to 'fuse' the units, just add a condition to the triggers in steps 2-4 that tells them to work only if 'Switch 1' is set, and create a triggers that Sets that switch when you step with your civilian on that beacon.
Zealot, Corsair, Player 1, Player 2, 'Switch 1', and the location named 'Hero' were just examples, you can replace them with whatever you need.
if it's not what you asked...
QUOTE
You take a ground unit and an air unit and put them on seperate beacons, and then take your handy civ and 'fuse' them. It's pretty much giving control of your air unit to a computer player (that's allied with you), while you still retain control of the ground unit. Moving the ground unit moves the air unit.
