Lever rewards/vocation based

[Jojjo]

Hello,

I got this script for level rewards and it works perfect but I want to edit it so it's vocation based.

local rewards = {
    [SKILL_LEVEL] = {
        {lvl = 9, items = {{2152, 2}}, storage = 54779},
    },
}

function onAdvance(player, skill, oldlevel, newlevel)
    local rewardstr = "Items received: "
    local reward_t = {}
    if rewards[skill] then
        for j = 1, #rewards[skill] do
            local r = rewards[skill][j]
            if not r then
                return true
            end

            if newlevel >= r.lvl then
            if player:getStorageValue(r.storage) < 1 then
                    player:setStorageValue(r.storage, 1)
                    for i = 1, #r.items do
                        local itt = ItemType(r.items[i][1])
                        if itt then
                            player:addItem(r.items[i][1], r.items[i][2])
                            table.insert(reward_t, itt:getName() .. (r.items[i][2] > 1 and " x" .. r.items[i][2] or ""))
                        end
                    end
                end
            end
end
   
        if #reward_t > 0 then
            player:sendTextMessage(MESSAGE_STATUS_CONSOLE_ORANGE, rewardstr .. table.concat(reward_t, ", "))
        end
    end
    return true
end

function onLogin(player)
    player:registerEvent("onadvance_reward")
    return true
end

Can someone help me please?

Thanks in advance

Ps: I didn't make this script, Zbizu did.
