I want make random sounds for sword like when you use slash you can get sound1 or sound2?

Do

Sound:Play()

If you want random sounds to play, this should do it.

local soundPlayed

local SlashSound = Instance.new("Sound")
SlashSound.SoundId = "rbxassetid://211059855"
SlashSound.Parent = sword
SlashSound.Volume = .7

local LungeSound = Instance.new("Sound")
LungeSound.SoundId = "rbxassetid://357622136"
LungeSound.Parent = sword
LungeSound.Volume = .6

local UnsheathSound = Instance.new("Sound")
UnsheathSound.SoundId = "rbxassetid://211059653"
UnsheathSound.Parent = sword
UnsheathSound.Volume = 1

function playSound()
    soundPlayed = math.random(0,2)
    if soundPlayed = 0 then
        SlashSound:Play()
    elseif soundPlayed = 1 then
        LungSound:Play()
    elseif soundPlayed = 2 then
        UnsheathSound:Play()
    end
end

Call playSound() for a random sound from your list. I have not tested it, so please check for errors. I hope this helps.
