[Scripting] Vocation Tree (Promotion) Request

[Jabbawack]

Hello, thank you for taking a look at my request.

I would like to request if someone could script a vocational promotion tree NPC.

Basically, it's when you go get a promotion from an NPC, and instead of being promoted to one vocation above the previous one, you have the option to choose between several vocations.

For example:

.....__Warrior__
....|...............|
Paladin......Barbarian

MindRage took the liberty of creating a rough draft of something that may help with the script, so use this at your own will, if it can help create this script. Honestly, since I'm not much of a scripter, I don't know exactly what to do with it.

--Vocation IDs
local Apprentice = 1
local Wizard = 8
local Mage = 11
 
local VocationTree = 
{
[Apprentice] = {Wizard, Mage};
}
function getAvailableVocationNames(vocation)
 local t = {}
 for id, data in pairs(VocationTree[vocation]) do
  t:insert(getVocationName(vocation))
 end
 return t
end
function onEvent(cid, words)
local voc = getPlayerVocation(cid)
 if VocationTree[voc] then
  local x = getAvailableVocationNames(voc)
  doSendPlayerMessage(cid, "You can be promoted to " .. x.Serialize());
 else
  --Vocation doesn't have any more promotions
  doSendPlayerCancel(cid, "You already have the last promotion!");
 end
end

If anyone thinks that they are skilled enough to do this, much would be appreciated, and I will rep+. (Plus mention your name in server credits)

Thank-you for your time,
