For a pirate roleplaying gametype, the amount of money a player has is made persistent by storing it in his account. Note the code uses "piraterpg.money" as key instead of just "money", as the player may be participating in other gametypes that also save his money amount to his account. If both gametypes would use "money" as the account key, they'd overwrite each other's data.

示例

For a pirate roleplaying gametype, the amount of money a player has is made persistent by storing it in his account. Note the code uses "piraterpg.money" as key instead of just "money", as the player may be participating in other gametypes that also save his money amount to his account. If both gametypes would use "money" as the account key, they'd overwrite each other's data.

function onPlayerQuit()
      local playerAccount = getPlayerAccount(source) -- 获取他的账户
      if (playerAccount) then -- 如果确认账户存在
            local playerMoney = getPlayerMoney(source) -- 获取他的金钱
            setAccountData(playerAccount, "piraterpg.money", playerMoney) -- 把他现在的钱存到他的账户里
      end
end
addEventHandler("onPlayerQuit", root, onPlayerQuit) -- 添加事件处理程序

function onPlayerLogin(_,account)
    local playerMoney = getAccountData(account, "piraterpg.money") -- get the money amount was store in his account data
    -- make sure there was actually a value saved under this key (check if playerMoney is not false).
    -- this will for example not be the case when a player plays the gametype for the first time
    if (playerMoney) then
        setPlayerMoney(source, playerMoney)
    end
end
addEventHandler("onPlayerLogin", root, onPlayerLogin) -- 添加事件处理程序
