【引擎触发】魔龙血域：限时开放地图的时间窗与产出调控

---开放时段：12-14 与 20-22 两个窗口
local WINDOWS = { { 1200, 1400 }, { 2000, 2200 } }

function Blood.isOpen(now)
    local hm = tonumber(os.date("%H%M", now))
    for _, w in ipairs(WINDOWS) do
        if hm >= w[1] and hm <= w[2] then return true end
    end
    return false
end

---入场：时间窗与令牌双校验
function Blood.enter(actor)
    if not Blood.isOpen(os.time()) then
        sendmsg(actor, 1, "血域未开放，时段 12-14 点与 20-22 点")
        return false
    end
    if not checkitemw(actor, "魔龙令牌", 1) then
        sendmsg(actor, 1, "需要魔龙令牌")
        return false
    end
    takeitem(actor, "魔龙令牌", 1, 0, "血域门票")
    mapmove(actor, "blood_land", 50, 50, 0)
    return true
end

---刷新密度随在场人数自适应
setontimerex(62, 15)
function Blood.spawnTick()
    if not Blood.isOpen(os.time()) then return end
    local n = Blood.onlineCount()
    if n <= 0 then return end
    local density = n > 50 and 2 or 1
    for i = 1, density do
        genmon("blood_land", math.random(40, 160),
            math.random(40, 160), "魔龙血卫", 2, 1, 0)
    end
end
