So i have this super saiyan script and i need help to get it to run. Here is the code: jun = game.Players.NAMEHERE Stuff = false function ssj() jun.Character.Humanoid.WalkSpeed=65 if Stuff == false then Stuff = true for u, c in pairs (jun.Character:GetChildren()) do if c.className == "Hat" and c.Name ~= "Swordpack" and c.Name ~= "GlassesBlackFrame" then c.Handle.Transparency = 1 end end Hair22 = Instance.new("Part") Hair22.Parent = jun.Character Hair22.Name = "Hair" Hair22.formFactor = "Symmetric" Hair22.Size = Vector3.new(1, 1, 1) Hair22.CFrame = jun.Character.Head.CFrame Hair22:BreakJoints() Hair22.CanCollide = false Hair22.TopSurface = "Smooth" Hair22.BottomSurface = "Smooth" Hair22.BrickColor = BrickColor.new("Bright yellow") Weld = Instance.new("Weld") Weld.Part0 = jun.Character.Head Weld.Part1 = Hair22 Weld.Parent = jun.Character.Head Weld.C0 = CFrame.new(0, 0.26, 0.06)CFrame.fromEulerAnglesXYZ(0, 0, 0) Mesh = Instance.new("SpecialMesh") Mesh.Parent = Hair22 Mesh.MeshType = "Sphere" Mesh.Scale = Vector3.new(1.3, 1.3, 1.3) Hair4 = Instance.new("Part") Hair4.Parent = jun.Character Hair4.Name = "Hair" Hair4.CanCollide = false Hair4.Locked = true Hair4.TopSurface = "Smooth" Hair4.BottomSurface = "Smooth" Hair4.formFactor = "Symmetric" Hair4.BrickColor = BrickColor.new("Bright yellow") Hair4.CFrame = jun.Character.Torso.CFrame Hair4.Size = Vector3.new(3, 3, 3) Weld = Instance.new("Weld") Weld.Parent = jun.Character.Head Weld.Part0 = jun.Character.Head Weld.Part1 = Hair4 Weld.C0 = CFrame.new(0, 1, 0) Mesh = Instance.new("SpecialMesh") Mesh.Parent = Hair4 Mesh.Scale = Vector3.new(1.15, 1.8, 1.26) Mesh.MeshType = "FileMesh" Mesh.MeshId = "http://www.roblox.com/asset/?id=12212520" Mesh.TextureId = "" Effect = Instance.new("Part") Effect.Parent = jun.Character Effect.Anchored = true Effect.CanCollide = false Effect.Size = Vector3.new(1, 1, 1) Effect.formFactor = "Symmetric" Effect.Transparency = 0.5 Effect.BrickColor = BrickColor.new("Bright yellow") Effect.TopSurface = "Smooth" Effect.BottomSurface = "Smooth" EffectMesh = Instance.new("CylinderMesh") EffectMesh.Parent = Effect EffectMesh.Scale = Vector3.new(1, 1500, 1) --[[ex = Instance.new("Explosion") ex.Position = jun.Character.Torso.Position ex.BlastPressure = 0 ex.Parent = workspace]] jun.Character.Torso.CFrame = jun.Character.Torso.CFrame * CFrame.new(0, 0.1, 0) for i = 1 , 20 do Effect.CFrame = CFrame.new(jun.Character.Torso.Position) EffectMesh.Scale = EffectMesh.Scale + Vector3.new(2, 0, 2) Effect.Transparency = Effect.Transparency + 0.025 wait(0.06) end Effect:Remove() if jun.Character.Torso:findFirstChild("PwnFire") == nil then pie = Instance.new("Fire") pie.Name = "PwnFire" pie.Parent = jun.Character.Torso pie.Size = 20 pie.Color = BrickColor.new("Bright yellow") end if jun.Character.Torso:findFirstChild("PwnSparkles") == nil then pie = Instance.new("Sparkles") pie.Name = "PwnSparkles" pie.Parent = jun.Character.Torso pie.Color = BrickColor.new("Bright yellow") end jun.Character.Humanoid.MaxHealth = jun.Character.Humanoid.MaxHealth1.5 wait(0.3) jun.Character.Humanoid.Health = jun.Character.Humanoid.Health*1.5 end end function nossj() jun.Character.Humanoid.WalkSpeed=16 if Stuff == true then Stuff = false if jun.Character.Torso:findFirstChild("PwnFire") ~= nil then jun.Character.Torso:findFirstChild("PwnFire"):Remove() end if jun.Character.Torso:findFirstChild("PwnSparkles") ~= nil then jun.Character.Torso:findFirstChild("PwnSparkles"):Remove() end p = Instance.new("Part") p.Parent = jun.Character p.Anchored = true p.CanCollide = false p.Transparency = 0.1 p.formFactor = "Symmetric" p.Size = Vector3.new(22, 22, 22) p.TopSurface = "Smooth" p.BottomSurface = "Smooth" p.Name = "Sharingan" p.Shape = "Ball" p.CFrame = jun.Character.Torso.CFrame p.BrickColor = BrickColor.new("Bright yellow") for i = 1 , 10 do wait(0.05) p.Size = p.Size + Vector3.new(-4, -4, -4) p.Transparency = p.Transparency + 0.1 p.CFrame = jun.Character.Torso.CFrame end p:Remove() for u, c in pairs (jun.Character:GetChildren()) do if c.className == "Hat" and c.Name ~= "Swordpack" and c.Name ~= "GlassesBlackFrame" then c.Handle.Transparency = 0 end if c.Name == "Hair" then c:Remove() end end jun.Character.Humanoid.Health = jun.Character.Humanoid.Health/1.5 wait(0.3) jun.Character.Humanoid.MaxHealth = jun.Character.Humanoid.MaxHealth/1.5 end end jun.Chatted:connect(function(Msg) msg = Msg:lower() if string.sub(msg, 1, 13) == "super saiyan 2" then wait(0.1) ssj() end if string.sub(msg, 1, 4) == "ssj2" then wait(0.1) ssj() end if string.sub(msg, 1, 4) == "off2" then wait(0.1) nossj() end end) function OnDeath()
