Animation2.AnimationId = "rbxassetid://4578997919"
local LoadedAnimation2 = Humanoid:LoadAnimation(Animation2)
local UIS = game:GetService("UserInputService")

UIS.InputBegan:Connect(function(input, GPE)
    if not GPE then
        if input.KeyCode == Enum.KeyCode.Q then
            if game.ReplicatedStorage.Value.Value == 0 then
	script.Sound:Play()
	LoadedAnimation:Play()
	
	game.ReplicatedStorage.AttackVal.Value = 1 wait (1/4)
	game.ReplicatedStorage.AttackVal.Value = 0
      elseif game.ReplicatedStorage.Value.Value == 1 then
	
	script.Sound:Play()
	LoadedAnimation2:Play()
	game.ReplicatedStorage.AttackVal.Value = 0
	game.ReplicatedStorage.Value.Value = 0
