How to walk to a randomized "effect tile"

Hi,

I was wondering how could I make a bot script to go pick up/walk onto a tile that has this kind of script:

function sendRandom(r)
return math.random(-r, r)
end

local version = 1098

-- you can put these in global
ORB_TIME = 16
ORB_INCREMENTS = 1000
--

function cashRandom(min, max)
return math.random(min, max)
end

function comma_value(amount)
local formatted = amount
while true do
formatted, k = string.gsub(formatted, "^(-?%d+)(%d%d%d)", '%1,%2')
if (k==0) then
break
end
end
return formatted
end

function getExpForLevel(level)
level = level - 1
return ((50 * level * level * level) - (150 * level * level) + (400 * level)) / 3
end

function giveMoney(m)
local g = m
local nug, cc, plat, gold, t = 1000000, 10000, 100, 1, {}
while(m ~= 0) do
if m >= nug then
local c = m / nug
m = m - (c * nug)
table.insert(t, {2157, c}) -- nuggets
elseif m >= cc then
local c = math.floor(m / cc)
m = m - (c * cc)
table.insert(t, {2160, c}) -- crystal coin
elseif m >= plat then
local c = math.floor(m / plat)
m = m - (c * plat)
table.insert(t, {2152, c}) -- plat coins
elseif m >= gold then
local c = math.floor(m / gold)
m = m - (c * gold)
table.insert(t, {2148, c}) -- gold coins
end
end
return t, g
end

function sendOrbEffect(cid, tier)
local player = Player(cid)
if not player then
return false
end
local colors = {5,30,35,95,108,129,143,155,180,198,210,215}
local xp = player:getExperience()
local exp = getExpForLevel(player:getLevel() + 1)

local orbs = {
{
type_ = "cash",
name = "~* gold *~",

itemid = function(x)
local tier = x or 1
local cash = 0
local min_coin = (tier * 5)
