【案例复盘】活动叠加：多活动同开的产出失控复盘

-- 活动叠加：倍率乘法
local player = class(actor)
local function stackRate(player)
    local expRate = tonumber(getsysvar("RateExp") or 1)
    local dropRate = tonumber(getsysvar("RateDrop") or 1)
    local rebate = tonumber(getsysvar("RateRebate") or 1)
    local total = expRate * dropRate * rebate
    sendmsg(player, 1, 0, "当前综合产出倍率：" .. total .. " 倍。")
    return total
end

-- 叠加上限：总闸截断
local player = class(actor)
local RATE_CAP = 3
local function cappedRate(player)
    local total = stackRate(player)
    if total > RATE_CAP then
        setsysvarex("RateRebate", RATE_CAP / (tonumber(getsysvar("RateExp") or 1) * tonumber(getsysvar("RateDrop") or 1)), true)
        sendcentermsg(player, 255, 0, "活动叠加产出已达上限，超出部分自动截断。", 0, 8)
        return RATE_CAP
    end
    return total
end
