隐藏房间：暗门的触发条件设计

local function onWallHit(actor)
    openDoor()                      -- 一打就开，毫无探索感
end

local hits, openedAt = 0, 0
local function onWallHit(actor, x, now)
    if openedAt > 0 and now - openedAt < 60 then return end
    if x == 12 then
        hits = hits + 1
        if hits >= 3 then
            hits, openedAt = 0, now
            openDoor()
            sendmsg(actor, 1, "暗墙碎裂，隐藏房间开启60秒")
        end
