Command Button That Calls A Trigger To Run

[Beginner Modder]

Is it possible to create an ability that - when its command card button is pressed - will make a trigger run?

For example: I have created triggers that change terrain type to simulate road construction.

All I need to do now is create a button on the command card that will allow one of my custom "road construction units" to trigger the terrain changing trigger.

Is this possible? I guess I need to create a new ability for the custom unit. But I don't know how to link that new ability to my terrain changing trigger.

Event - Unit starts the effect of an ability
Condition - Ability being cast == your ability
Actions - your actions

OK. I think I get it. Now all I need is a button on the unit's command card to cast the ability.

I know that pre-loaded abilities come with their own command card buttons. How can I create a command button for my custom ability? Or should I just select a pre-loaded ability and simply change some stats, and just use the pre-loaded ability's command button?

Use Channel as the base ability. Set options to visible and disable other abilities to false. Set Hero ability to false. Add the ability to the unit's ability list.

Awesome, thanks.

PS... I guess there's no way to create our own icons for custom command buttons using MS Paint or other drawing program and then importing it into our maps, is there?

Yes, you can. See:

You can create your own and import them. If you need to add borders similar to the ones in wc3, simply use:

And feel free to look at our icon repository for icons to use. There are literally tons of them. Just be sure to give credits to the author:
