[Creatureevent] onMoveItem(cid, item, count, toContainer, fromContainer) TFS 0.3.6

Ele basicamente oferece todas as informações que você precisa e é mais avançado que o onThrow padrão (). 

 

Vamos Começar:

 

Em Creatureevent.cpp:

Exemplo de uso:

Em data/creaturescripts/creaturescripts.xml

Adicione:

 <event type="moveitem" name="MoveItem" event="script" value="moveitem.lua"/>

Crie um script na pasta data/creaturescripts/scripts/

Chamado moveitem.lua

Adicione:

function onMoveItem(cid, item, count, toContainer, fromContainer, fromPos, toPos)
    if item.actionid == 1000 then
        return false
    end
    return true
end

Em data/creaturescripts/scripts/login.lua:

Adicione:

registerCreatureEvent(cid, "MoveItem")

-> Bloquear itens com actionid 1000 de serem movidos (exemplo realmente simples)
