Dig Dig Dig!

Hey guys. I just thought of an awsome ability that would be perfect 4 my map. Its basicly burrow. Except you can move, like your digging a tunnel or something. So you are a burrowed ghool that can move around still. Now. I dont think you would actually have to put the unit a level below ground , but simply make its collision size 0.01 or something and also make it invisible by triggers.

To make a long story short, I need a trigger so that if a [player] selects [dig] ability, then the unit portrait changes to a burrowed crypt fiend or something like that. Im sure I could add the finnishing touches.
Any Ideas?

thx guys.
:D

Maybe changing the vertex code to make that unit invisible and then adding a FX in the foot of that unit so this would be like:

EVENT A units is issued an order
CONDITION Isuued Order is "dig"(the spell this is based on)
ACTION
Animation -Change the vertex animation of <unitvariable> to blah blah...(just make it invisible)
Special Effect -Add the <Burrow Fiend> Special effect to "foot"(or origin use whichever you want) in unitvariable

that shoulda work (of course the names of the triggers are other but dont remenber "exzactly" )

Hope it Work :D

hey thx man ill try that. it soundz good

... hey guys. allot of you who read this will be falling on ur face about how much of a newbish question this is but... how do you make an empty. (an ability that does nothing). I need this so I can actually add triggers to the dig ability. (lol at least im slightly versed in GUI) lol

just take an abilty that suits your method of activation, in your case, instant no target, (warstomp for intance) and remove all the fields that give it its effects (dmg stun buffs duration etc) redo the tooltips and stuff and then use trigegr to detect its casting.
