You can learn only 2 spells from 3

[Koozaczek]

Like in thread.
How i can make that?
I mean it should wourk that the npc have 3 spells to learn, but you can learn only 2 from 3, you can choose what spells you want to learn and this 1 left spell will be impossible to learn you pernament.

Please help, also sorry for my bad english.

and conversation:
Player: Hi
Npc: Hello dear Player, i can teach you some interesting spells, but remember you cant learn it all.
Player: Spells
Npc: I can teach you spells: exura, exura gran, exura vita, exura san, exana mort. But remember, you can choose only 2 spells to learn from my list, other spells will be pernament not available to you.
Npc: So what spells you choose?
Player: Exura san
Npc: You learned spell Exura San
Player: Exana Mort
Npc: You learned spell Exana Mort
Player: Exura
Npc: Sorry, you already learned 2 spells from me, dont come back anymore.

Sorry for my bad english.
Could you help me?

make an storage value connected to the npc
if npc will say i have teach you exura san, then set storage +1

If player want to learn second spell, change storage into +2 storage...
And if player want to learn 3 spell, then send false ;p

Thx you a lot, work great.

Also can you tell me where i should change to be possible choose for example 3 or more spells to learn?

# Edit
Also can you fix to not be able to learn 2 the same spells?
At the moment i can learn for example light healing double time.

You can use getPlayerLearnedInstantSpell(cid, msg) to see if a player already learned the spell.
Change here the amount.

if getPlayerStorageValue(cid, storage) < 1 then

< 1 means -1 or 0, first it's -1 and + 1 it will be 0. So with 3 spells you can do < 2, since then it will be -1, 0 and 1.
