【策划架构】Lua反向索引：祖玛教主掉落物按名字一步定位

local function findItem(name)
    for i = 1, #loot do
        if loot[i].name == name then return i end   -- 每次扫500
    end
end

local loot, index = {}, {}
local function add(item)
    loot[#loot + 1] = item
    index[item.name] = #loot          -- 写入同步登记
end
add({name = "裁决之杖", rate = 500})
local function locate(name)
    return loot[index[name]]          -- 一步直达
end
sendmsg(actor, 1, "祖玛教主掉落 " .. locate("裁决之杖").name
    .. "，概率1/" .. locate("裁决之杖").rate)
