help with pet system

[Starliks]

found a pet system by letter, and well what i need to follow the below content

Create a file called LUA cardsytem in your home folder OTServ (where is your executable, dlls and config.lua)
tab = {
["Bug"] = {"bug", 50001, 1},
["Troll"] = {"troll", 50002, 40},
["Demon"] = {"demon", 50003, 80}
}

Now go and create a lib file called MOON card and put this:


function doPlayerStartCards(cid, namecard, pos)
dofile("./cardsytem.lua")
local n = namecard
local monster = tab[n]

pk = doSummonCreature(monster[1], pos)
doConvinceCreature(cid, pk)
return true
end
function doShowTextDialgListCards(cid, itemid)
dofile("./cardsytem.lua")
local n = namecard
local str = ""
str = str .. "Cards :\n\n"
for name, tab in pairs(tab) do
str = str..name.."\n"
end
str = str .. ""
doShowTextDialog(cid, itemid, str)
return TRUE
end

function getPlayerCard(cid, namecard)
dofile("./cardsytem.lua")
local n = namecard
local card = tab[n]
local cardname = card[2]
local cardnumber = getPlayerStorageValue(cid, cardname)
return cardnumber
end

function doPlayerAddNewCards(cid, namecard)
dofile("./cardsytem.lua")
local n = namecard
local newcard = tab[n]
setPlayerStorageValue(cid, newcard[2], 1)
return true
end
function getLevelCard(namecard)
dofile("./cardsytem.lua")
local n = namecard
local newcard = tab[n]
local cardlevel = newcard[3]
return cardlevel
end
function getCardprice(namecard)
dofile("./cardsytem.lua")
local n = namecard
local newcard = tab[n]
local newcardlevel = newcard[3]*4
return newcardlevel
end
function getCardId(namecard)
dofile("./cardsytem.lua")
local n = namecard
local newcard = tab[n]
local pricecard = newcard[2]-50000
return pricecard
end
function getPlayerPositionPz(cid)
local pz = getTilePzInfo(getCreaturePosition(cid))
return pz
end

function getCardStorage(namecard)
dofile("./cardsytem.lua")
local n = namecard
local newcard = tab[n]
local pricecard = newcard[2]
return pricecard
end
function getExistNameCard(namecard)
dofile("./cardsytem.lua")
local monster = tab
return monster[namecard]
end
