[Toadette2011]

Hello everyone. I am creating a map for custom campaign. I was trick in one trigger. For example, on the Orc Campaign Chapter 1. There is one unit event. There are Tauren and Centaurs unit, and they were hided. But when the player group come to the area that have those units, they appear. And the centaurs were attacking tauren. It is mean the event happen. That is the one that I stuck on this. So, could you please help me.

Why does this marked as solved?

Anyway, make the taurens and centaurs allies then make them enemies once the player reaches the area.
