Buildings over/under player

[Frankmank]

I'm making an RPG, and all the artwork is isometric, so i'm wondering how I can make a building go over the player when their behind it and under them when they're infront, so far I can only do it with one corner, if the building has 3 corners exposed it doesn't work, help please.

onClipEvent(load){
this.gotoAndStop(2);
}
onClipEvent(enterFrame){

if (_root.player._y <= 101.7){
		this.gotoAndStop(1);
}
else this.gotoAndStop(2);
}

You should look into swapDepths and other depth related actionscript.

player.swapDepths(player._y)
buildings.swapDepths(buildings._y)

you get the idea ;) go look it up
