I noticed your script has everything combined onUse, onLogin, and onSay all in the same file: data/actions/scripts/exp_potion.lua.
That won't work like that.
This kind of setup would only work if you're using mods. In that case, you can put everything into a single script, and the server will load it automatically without needing to register anything in the XML.
But the way it is now (under actions), you can't mix all those functions in one file. You need to separate each function into its appropriate place.

So, I made it here for you mods

I recommend that you stop using TFS 0.x and migrate to the latest TFS 1.x nekiro or Sarah 8.60 you can find. Nowadays, there are way more scripts available, ready-to-use systems, improvements, and an active community to help you out.
It's really hard to find people still working with TFS 0.x who can give support. Just my opinion, but I think it's definitely worth switching to TFS 1.x.

I recommend that you stop using TFS 0.x and migrate to the latest TFS 1.x nekiro or Sarah 8.60 you can find. Nowadays, there are way more scripts available, ready-to-use systems, improvements, and an active community to help you out.
It's really hard to find people still working with TFS 0.x who can give support. Just my opinion, but I think it's definitely worth switching to TFS 1.x.

This script does not work for tfs/otx 0.4, it was made only for 1.x+, the treatment of final experience feedback data is different.

This script was designed for TFS 0.x using mods, where it's perfectly normal to combine multiple functions (onUse, onLogin, onSay, etc.) into a single .lua file, which is automatically loaded via XML.
Yes, the experience feedback handling is different in version 1.x, but here the focus was on the 0.x structure. I used buypremium_command.xml from TFS 0.4 as a reference, which follows the same logic, and adapted the idea for exp_potion.xml.
I haven't tested it on a server yet, so it might need some adjustments but the approach is consistent with how mods work in TFS 0.x.

I noticed your script has everything combined onUse, onLogin, and onSay all in the same file: data/actions/scripts/exp_potion.lua.
That won't work like that.
This kind of setup would only work if you're using mods. In that case, you can put everything into a single script, and the server will load it automatically without needing to register anything in the XML.
But the way it is now (under actions), you can't mix all those functions in one file. You need to separate each function into its appropriate place.

So, I made it here for you mods
exp_potion.xml

Recomendo que você pare de usar o TFS 0.x e migre para o TFS 1.x nekiro ou Sarah 8.60 mais recente que encontrar. Hoje em dia, há muito mais scripts disponíveis, sistemas prontos para uso, melhorias e uma comunidade ativa para ajudar você.
É muito difícil encontrar pessoas que ainda trabalhem com o TFS 0.x e que possam dar suporte. É só a minha opinião, mas acho que definitivamente vale a pena migrar para o TFS 1.x.
[/QUOTE]

Error

Em primeiro lugar, agradeço por tentar ajudar!

Infelizmente, não consigo migrar para outras versões do TF. Só sei compilar usando DEV, sem contar que os scripts que eu uso parariam de funcionar, certo?
Esse é o meu "bloqueio" por não migrar!

Mateus Robeerto said:

I noticed your script has everything combined onUse, onLogin, and onSay all in the same file: data/actions/scripts/exp_potion.lua.
That won't work like that.
This kind of setup would only work if you're using mods. In that case, you can put everything into a single script, and the server will load it automatically without needing to register anything in the XML.
But the way it is now (under actions), you can't mix all those functions in one file. You need to separate each function into its appropriate place.

So, I made it here for you mods

@pisquila

I recommend that you stop using TFS 0.x and migrate to the latest TFS 1.x nekiro or Sarah 8.60 you can find. Nowadays, there are way more scripts available, ready-to-use systems, improvements, and an active community to help you out.
It's really hard to find people still working with TFS 0.x who can give support. Just my opinion, but I think it's definitely worth switching to TFS 1.x.

First of all, I appreciate you trying to help!

Unfortunately, I can't migrate to other versions of TF. I only know how to compile using DEV, and not to mention that the scripts I use would stop working, right?
That's my "block" for not migrating!

I recommend that you stop using TFS 0.x and migrate to the latest TFS 1.x nekiro or Sarah 8.60 you can find. Nowadays, there are way more scripts available, ready-to-use systems, improvements, and an active community to help you out.
It's really hard to find people still working with TFS 0.x who can give support. Just my opinion, but I think it's definitely worth switching to TFS 1.x.

It didn't work
No error, but it didn't add the exp bonus.

First of all, I appreciate you trying to help!

Unfortunately, I can't migrate to other versions of TF. I only know how to compile using DEV, and not to mention that the scripts I use would stop working, right?
That's my "block" for not migrating!

It didn't work
No error, but it didn't add the exp bonus.

There are alot tutorials how compile TFS 1.x in the forum just check it, your script is total wrong, what TFS are you using 3777?

Check my script and tell me if you find any errors and if the script works.

You will get way more problems than compile in DEV and some old scripts
Don't waste your time and change to TFS 1.5 8.60
You won't regret it once you changed everything
Annnnnnnd u will for sure lost few features like cliport for GM and cast system (if you even got it in your source) but nothing to cry about if you ask me xD

I had to download TFS 0.x to carefully fix the script...

Without any EXP bonus, I killed the rat and got 37 EXP.
With the bonus, I got 112 EXP.
Be happy use the script!

Primeiramente, agradeço por tentar ajudar!

Infelizmente, não consigo migrar para outras versões do TF. Só sei compilar usando DEV, sem contar que os scripts que eu uso parariam de funcionar, certo?
Esse é o meu "bloqueio" para não migrar!

Não funcionou
Nenhum erro, mas não adicionou o bônus de experiência.

First of all, I appreciate you trying to help!

Unfortunately, I can't migrate to other versions of TF. I only know how to compile using DEV, and not to mention that the scripts I use would stop working, right?
That's my "block" for not migrating!

It didn't work
No error, but it didn't add the exp bonus.

The tfs/otx2 experience treatment is from the "doPlayerSetExperienceRate" function, the mods are correct, what you will have to do is call the experience change through onLogin.

For example, you will use a local variable rate = 1 below you add which bonuses the server will have, for example if you use storage as a potion, check if the player has the storage and add rate = rate + "bonus", after going through all of them you trigger the function to change experience, "doPlayerSetExperienceRate(cid, rate)".

@

pisquila

Tive que baixar o TFS 0.x para corrigir o script com cuidado...

Sem nenhum bônus de EXP, matei o rato e ganhei 37 EXP.
Como bônus, ganhe 112 EXP.
Fique feliz usando o script!
