Minimap Icons

Hi guys :P

So... In the Bonus Campaign of TFT, there are "entrances" for other maps, that appear as "green icons" in the minimap. How can I do that, with my own icons?

And what does the action "Neutral Building - Set Minipam Special Icon" (or something similar) do?

Thanks for your time!

I think that uses an icon that shows on the minimap.

if that option does set the icon, make a building with no path/model/shadow and the locust ability, then give it a minimap icon and put it on the map

I don't know how much info you are looking for, but this old thread has pretty much all you could want to know about minimap icons.

The green entrances use those triggers and you can change the image during the game. It's cool, but you can only have one set of changing images that way when I was looking for more.

Oh... Sorry for lack of search :P
That topic really helps, Chaotic ^^

Thanks everyone!
