【入门夯实】Lua数组打平：裁决之杖奖励包的一层摊开

local function grant(actor, packs)
    for i = 1, #packs do
        -- 发放端却按一维取值，packs[i]是表不是元素
        giveitem(actor, packs[i], 1, 0, "奖励")  -- 类型错乱
    end
end

local function flat(packs)
    local out = {}
    for i = 1, #packs do
        local p = packs[i]
        for j = 1, #p do
            out[#out + 1] = p[j]      -- 嵌套逐层摊开
        end
    end
    return out
end
local items = flat({{"金条", 5}, {"裁决之杖", 1}})
sendmsg(actor, 1, "奖励摊平 " .. #items .. " 项")
