Como verifico que umas pos é andavel?

tenho esse script que jorra itens pelo mapa em uma determinada area, so que ele cria itens ate nas paredes. acho que se verrificasse se as pos fossem andaveis antes de criar o item no chão ja resolveria...
alguém pode me ajudar?

Tenta mudar aquela função isWalkable por essa aqui:
 

function isWalkable(pos)
	local tile = getThingfromPos(pos)
	
	if hasProperty(tile.uid, 0) == true or hasProperty(tile.uid, 3) == true then 
    	return false
	end
	return true
end

E depois troca essa parte:
 

if isWalkable(pos, true, false, true) then

Por:
 

if isWalkable(pos) then

Valeu!!
