and this is the script

function onSay(cid, words, param, channel)
	local n = 1
	if(param ~= "" and tonumber(param)) then
		n = tonumber(param)
	end

	local pos = getPosByDir(getCreaturePosition(cid), getPlayerLookDir(cid), n)
	pos.stackpos = STACKPOS_GROUND
	if(getTileThingByPos(pos).uid == 0) then
		doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_BLUE, "You cannot teleport there.")
		return TRUE
	end

	pos = getClosestFreeTile(cid, pos, FALSE, FALSE)
	if(pos == LUA_ERROR or isInArray({pos.x, pos.y}, 0) == TRUE) then
		doPlayerSendTextMessage(cid, MESSAGE_STATUS_CONSOLE_BLUE, "Destination not reachable.")
		return TRUE
	end

	local tmp = getCreaturePosition(cid)
	if(doTeleportThing(cid, pos, TRUE) ~= LUA_ERROR and isPlayerGhost(cid) ~= TRUE) then
		doSendMagicEffect(tmp, CONST_ME_POFF)
		doSendMagicEffect(pos, CONST_ME_TELEPORT)
	end

	return TRUE
end

I will give rep + + to help me

lib/function:

function getPosByDir(fromPosition, direction, size)
local n = size or 1
local pos = fromPosition
if(direction == NORTH) then
pos.y = pos.y - n
elseif(direction == SOUTH) then
pos.y = pos.y + n
elseif(direction == WEST) then
pos.x = pos.x - n
elseif(direction == EAST) then
pos.x = pos.x + n
elseif(direction == NORTHWEST) then
pos.y = pos.y - n
pos.x = pos.x - n
elseif(direction == NORTHEAST) then
pos.y = pos.y - n
pos.x = pos.x + n
elseif(direction == SOUTHWEST) then
pos.y = pos.y + n
pos.x = pos.x - n
elseif(direction == SOUTHEAST) then
pos.y = pos.y + n
pos.x = pos.x + n
end

return pos
end
