Gate with a button to open.

Alright, I am making a map where I would like it so I would just press a button and the gate would open like I've seen in the empire building map whatever that one is called, I thought about using the bear form as a base for it but I got everything done but making it look like the door is open. Is it impossible? I can make it a trigger ability if I need to but I would rather not if its at all possible, and after all WC3Campaings is where the 'perts are at. =) Thx in advance!

Create a new trigger

Chat command open gate

Event - Player chat message
Player one (red) types a chat message containing -open gates as An exact match

Switch, lever, unit event open gate

Event - Destructible dies
Condition - Destructible-Type Comparison
Destructible equal to lever/footswitch
Event - A unit dies
Condition - Unit equal to gate guardian

Add this on of course to either of event/conditions:

Action - Destructible open/close/destroy gate.
Open gate 1

I dont think you understood, I know how to do triggers for it (i have one working right now until i can figure this out) but I want to know If I can make a button literally when you select the gate. I know hwo to make trigger spells too, I just want to know if you can mess with the rules enough so you can use Bear form or any other spell to change the gate from closed to open without triggers, but I will make it a trigger ability if need be.

Dont think you can, unless you make a dummy unit in the gate or something, and somehow get the player to select that
