obj Floor icon = 'floor.dmi' turf Grass icon = 'grass.dmi' cantbuild = 1 mob verb Build() for(var/turf/T in src.loc) if(T.cantbuild) src << "Get off Mr T's bus f00." return new /obj/Floor(src.loc)
In this example, if a player were to use the verb Build() on the grass turf, it would output the message "Get off Mr T's bus f00." and won't allow them to place anything there.
First, that's wrong. Second, don't hand code out on a silver platter. It doesn't help anyone, and it's likely Loa will just come back asking "How do I make it so you can't buil on water?"
