【入门夯实】Lua映射变换：裁决之杖价目表的整体调价

local function adjust(actor, prices, pct)
    for k, v in pairs(prices) do
        prices[k] = math.floor(v * pct)  -- 原地改，无法回滚
    end
end

local function mapPrice(prices, pct)
    local out = {}
    for k, v in pairs(prices) do
        out[k] = math.floor(v * pct)   -- 变换写入新表
    end
    return out
end
local newPrices = mapPrice(PRICE, 1.05)
sendmsg(actor, 1, "裁决之杖调价后 "
    .. newPrices["裁决之杖"] .. " 金")
