【入门夯实】math.randomseed的随机质量：可复现与碰撞防控

math.randomseed(0)
local drop = math.random(1, 10000)

local function initRandom()
    local seed = os.time() * 1000 + math.floor(os.clock() * 1000)
    math.randomseed(seed)
end
initRandom()
local drop = math.random(1, 10000)

local function testRandom(count)
    local seen = {}
    local dup = 0
    for i = 1, count do
        local v = math.random(1, count)
        if seen[v] then
            dup = dup + 1
        end
        seen[v] = true
    end
    return dup
end

local function replayWithSeed(seed, count)
    math.randomseed(seed)
    local result = {}
    for i = 1, count do
        result[i] = math.random(1, 10000)
    end
    return result
end
