Player-Owned-Gate with Open/Close Ability

I need help creating a Player-Owned-Gate with Open/Close Ability.

Tried using the Night Elf Transform ability, it seems to work fine until I play its animations and I get an error.

Is there a way to fix this problem or any other way to create a Player-Owned-Gate with Open/Close Ability. Any help would very much be appreciated!!

Make sure you use Death Alternate in "Art - Animation Name".
If that dont work or if you already have tried it i dont know how to fix it...

Elaborate on what you want.

Who should have the ablity? A hero, a unit?
How close should they stand to the gate?
Do you want the gate to have the ability?
Is the gate a unit?

yeah just make a unit with the gate model and then make a dummy ability that when used, replace it with another unit with a model of an opened gate with the close ability. maybe that'll work?

I Would Suggest maybe make a "Gate Keeper" with that skill :P sounds nicer :D

not if you need to be able to build gates with a peasant.
