【进阶实战】Lua select数参：沙巴克组队分经验的尾部到账

local function shareExp(base, ...)
    local n = #arg                  -- 5.1 函数体内 arg 为 nil
    local tail = base * 0.2 / n     -- 除 nil，直接报错
end

local function shareExp(base, ...)
    local n = select("#", ...)         -- 真实个数
    local tail = math.floor(base * 0.2 / n)
    for i = 1, n do
        local mate = getplayerbyname(select(i, ...))
        if mate then
            setplayvar(mate, "EXP_ADD", tail)
            sendmsg(mate, 1, "沙巴克分成 " .. tail .. " 经验")
        end
    end
end
