【Lua实战】强化幸运波动：幸运曲线的数值实现

local function luckyRate(cnt)
    local base = 60
    local wave = math.sin(cnt * 0.35) * 15
    local noise = math.random(-3, 3)
    local rate = base + wave + noise
    return math.max(30, math.min(90, rate))
end
local function tryStrengthen(actor, cnt)
    local player = class(actor)
    local rate = luckyRate(cnt)
    if math.random(1, 100) <= rate then
        giveitem(actor, "强化成功凭证", 1)
        sendmsg(actor, 0, "强化成功（本次成功率" .. rate .. "%）")
        return true
    end
    sendmsg(actor, 0, "强化失败，本次成功率" .. rate .. "%")
    return false
end

local function peakPreview(cnt)
    local phase = math.floor((cnt % 18) / 9)
    if phase == 1 then
        return "幸运上升期"
    end
    return "幸运平稳期"
end
