【Lua实战】配置热更安全点：热更时机的选择与保护

-- 配置热更：安全点标记
local player = class(actor)
local inTransaction = false
local hotfixQueued = false
local function enterTransaction(player)
    inTransaction = true
    setplayvar(player, "HUMAN", "TxFlag", 1, true)
end
local function exitTransaction(player)
    inTransaction = false
    setplayvar(player, "HUMAN", "TxFlag", 0, true)
    if hotfixQueued then
        hotfixQueued = false
        applyHotfix(player)
    end
end

-- 热更执行：影子表切换
local player = class(actor)
local activeCfg, shadowCfg = {}, {}
local function applyHotfix(player)
    shadowCfg = loadNewConfig()
    if shadowCfg.maxDrop == nil or shadowCfg.maxDrop < 1 then
        sendmsg(player, 1, 0, "新配置校验失败，热更已回滚。")
        return
    end
    activeCfg = shadowCfg
    sendmsg(player, 1, 0, "配置热更完成，maxDrop=" .. activeCfg.maxDrop)
end
local function loadNewConfig()
    return {maxDrop = tonumber(getsysvar("NewMaxDrop") or 100)}
end
