【引擎触发】科举答题：传奇知识问答的防作弊与奖励设计

---答题判定：服务端持有正确答案
function Quiz.answer(actor, qid, idx)
    if os.time() - (actor.quizStart or 0) < 2 then
        sendmsg(actor, 1, "作答过快，请稍候")
        return false
    end
    local q = QUIZ_POOL[qid]
    if not q then return false end
    local correct = (idx == q.answer)
    if correct then
        actor.quizScore = (actor.quizScore or 0) + 1
    end
    return correct
end

---结算：全对拿状元，其余按对题数给奖
function Quiz.finish(actor)
    local score = actor.quizScore or 0
    if score == #QUIZ_POOL then
        if Quiz.zhuangyuanCount < 3 then
            Quiz.zhuangyuanCount = Quiz.zhuangyuanCount + 1
            setranklevelname(actor, "科举状元")
            giveitem(actor, "状元礼盒", 1)
            QF_Broadcast(actor:GetName() .. " 金榜题名，荣膺科举状元")
        else
            giveitem(actor, "进士礼盒", 1)
        end
    else
        giveitem(actor, "答卷奖励", score)
    end
    actor.quizScore = 0
end
