Current questions and answers regarding the map editor.

where did you get this from? I don't have these functions in the official manuals.

Ah, okay, it worked now.
function regF()
sulfur=GetPlayerResource(1, 4);

SetPlayerResource(1, 4, sulfur-10);
end;
end;
Trigger(REGION_ENTER_AND_STOP_TRIGGER, "reg", "regF");
