【高级技巧】Lua敏感词扫描：沙巴克喊话的词表命中统计

local function scan(actor, text)
    for _, w in ipairs(WORDS) do
        text = string.gsub(text, w, "*")   -- 80遍替换不留痕
    end
    return text                     -- 命中次数全丢
end

local WORDS = {"代练", "金币", "裁决之杖"}
local function scan(actor, text)
    local hits, n = {}, 0
    for _, w in ipairs(WORDS) do
        local c = select(2, string.gsub(text, w, "*"))
        if c > 0 then
            hits[w] = c
            n = n + 1
        end
    end
    sendmsg(actor, 1, "沙巴克喊话命中 " .. n .. " 类词")
    return hits
end
