【高级技巧】Lua unpack展开：烈火剑法连招的动态传参

local function castCombo(actor, delays)
    -- 手写展开：段数一改就要同步改这行
    local ms = delays[1] + delays[2] + delays[3] + delays[4]
    sendmsg(actor, 1, "连击总窗 " .. ms .. " 毫秒")
end

local function totalWindow(...)
    local sum = 0
    for i = 1, select("#", ...) do
        sum = sum + select(i, ...)
    end
    return sum
end
local function castCombo(actor, delays)
    sendmsg(actor, 1, "烈火四段连击总窗 "
        .. totalWindow(unpack(delays)) .. " 毫秒")
end
