【入门夯实】掉落少一件：数组从1开始的下标习惯

local drops = {}
drops[0] = "金创药"
drops[1] = "祝福油"
drops[2] = "金条"
sendmsg(nil, 1, "掉落表共 " .. #drops .. " 种")

local drops = { "金创药", "祝福油", "金条" }
local function rollDropItem()
    return drops[math.random(1, #drops)]
end
local function showDrops(actor)
    actor = getplayerbyname(actor)
    sendmsg(actor, 1, "白野猪掉落池共 " .. #drops ..
        " 种，本次抽取：" .. rollDropItem())
end

local function safeGet(list, idx)
    if idx < 1 or idx > #list then
        return nil
    end
    return list[idx]
end
