Conditions

The Conditions tab is used to make certain actors appear and disappear from the map when a certain number of another actor is on the map. Appear conditions make actors appear while disappear conditions erase an actor from the map. The actor that appears or disappears is the one that you are working on at the moment, and the one that controls the appearance and disappearance is the actor that you specify in the Conditions tab.

Suggestions for conditions
