Special Effect Problem

ok i got a special effect to work on a unit (weapon/armor addon) now i have a problem... ok when i do the special effect it works.. but im making a map where u have to pick a unit you want so u can play as him.. ok when i add the special effect.. it only stays on that unit.. when a player picks the unit with the special effect.. it doesnt stay on the unit.. y question is.. how do i make a trigger so after a player picks the person with the special effect.. it will stay on the "player picked" person?

Do you create a new unit of the same type after the player picked it?

If you just move the unit and change owner it should work nice,
But if you create a new unit identical to the unit shoosen you got to add a F/X to the new unit to.

Action - set "Special effect" at "origin" of (last created unit)

this could be a trigger that would work:

event-A unit enters playable map area
condition-Unit type equals to (unit)
Action-Attach special effect to triggering unit at (the location of the attached special effect)

heh yea i figured that out a long time ago=D just didnt check the thread. thanx anyways=)
