I tried this
player = game.Players.LocalPlayer character = player.Character Character.WalkSpeed = 50
Not working :(
Place in a "localscript" in the startergui you also forgot to add humanoid also change the first C in line 3 to a lower case one
The script should look like this
player = game.Players.LocalPlayer character = player.Character character.Humanoid.WalkSpeed = 50
