【Lua实战】权重抖动：固定概率的微随机处理

-- 权重抖动：概率浮动
local player = class(actor)
local BASE_RATE = 0.15
local function rollWithJitter(player)
    local jitter = 0.95 + math.random() * 0.1
    local rate = BASE_RATE * jitter
    rate = math.max(0.01, math.min(0.99, rate))
    return math.random() < rate
end

-- 收敛验证：批量模拟
local player = class(actor)
local function verifyJitter(player)
    local hits = 0
    local trials = 100000
    for i = 1, trials do
        if rollWithJitter(player) then hits = hits + 1 end
    end
    local actual = hits / trials * 100
    sendmsg(player, 1, 0, trials .. " 次模拟命中率 " ..
        string.format("%.2f", actual) .. "%，期望 15%。")
    return actual
end
