Fala, galerinha! Há um tempo atrás tinha feito esse sisteminha simples, como achei que não seria muito útil, acabou sumindo nas profundezas das pastas do meu computador. No entanto, como vi o pedido do membro @DboHere, acho que outras pessoas podem precisar.

 

Como funciona:

Uma key única que pode ser usada somente uma vez adicionará um item ao player quando for utilizada.

 

- Criando uma key contendo 10 crystal coins: 

!createkey 2160,10 ou !createkey crystal coin,10 

 

O player receberá a mensagem: "You have created the key: rXo-980376. You can add other items using !addkey."

 

- Adicionando novos itens à mesma key:

!addkey rXo-980376,2463,1

 

O player receberá a mensagem: "You have added other items to the key rXo-980376."

 

- Checando os itens que uma key possui:

!checkkey rXo-980376

 

 

- Utilizando a key o player receberá todos os itens associados a essa key. Depois disso, a key ficará inválida.

!key rXo-980376

 

- Deletando a key da database (apenas se necessário):

!deletekey rXo-980376

 

Configuração:

 

Execute o seguinte comando no mysql do seu servidor:

 

CREATE TABLE `code_key` (
    `id`         INT NOT NULL AUTO_INCREMENT,
    `key`        VARCHAR(255)       NOT NULL,
    `item_id`    INT                NOT NULL,
    `count`      INT                NOT NULL,
    `invalid`    INT      NOT NULL DEFAULT 0,
    PRIMARY KEY (`id`)
);

 

Em talkactions/scripts, crie um arquivo:

 

keysystem.lua

["!createkey"] = {access = 3},

Em "access" edite o grupo que pode utilizar cada comando. No exemplo abaixo, apenas players com acesso maior que 3 podem utilizar o comando !createkey.

 

["!createkey"] = {access = 3}, 

 

Em talkactions.xml, adicione a tag: <talkaction words="!key;!createkey;!deletekey;!checkkey;!addkey" event="script" value="keysystem.lua"/>

 

E é isso, espero que seja útil  

Funcionando Perfect....

Funcionando Perfeitamente em tfs 0.4.

Nice, Você ajudou por muitos anos obrigado.
