【框架设计】行会升级：建设度与等级权益

---行会建设度的汇入
function Guild.addBuild(actor, amount)
    local player = class(actor)
    if not player then return false end
    local gid = getplayvar(actor, 2, "GuildId")
    if not gid or gid == "" then
        sendmsg(actor, 1, "加入行会后才能捐献")
        return false
    end
    local g = Guild.of(gid)
    g.build = g.build + amount
    -- 个人贡献同步累积
    local pt = tonumber(getplayvar(actor, 2, "GuildPoint")) or 0
    setplayvar(actor, "HUMAN", "GuildPoint", pt + amount, 1)
    sendmsg(actor, 1, "建设度 +" .. amount .. "，个人贡献 +" .. amount)
    return true
end

---行会升级：等级与权益的解锁
local GUILD_LEVELS = {
    { lv = 2, need = 100000, perk = "仓库 150 格" },
    { lv = 3, need = 300000, perk = "攻城资格" },
    { lv = 4, need = 800000, perk = "行会商店二货架" },
    { lv = 5, need = 2000000, perk = "守护兽上限 +1" },
}

function Guild.checkLevel(gid)
    local g = Guild.of(gid)
    for i = #GUILD_LEVELS, 1, -1 do
        local cfg = GUILD_LEVELS[i]
        if g.level < cfg.lv and g.build >= cfg.need then
            g.level = cfg.lv
            QF_Broadcast("「" .. g.name .. "」升到 " ..
                cfg.lv .. " 级行会，解锁：" .. cfg.perk)
            return true
        end
    end
    return false
