        if looping == false then
            looping = true
            while looping == true do
    for _, v in pairs(game.Players:GetPlayers()) do
                        print("stun hmmmm!")
        if v.Character ~= player.Character then
            if (v.Character.Head.Position - player.Character.Head.Position).magnitude <=15 then
                v.Character.Humanoid.WalkSpeed = 1
                v.Character.Humanoid.JumpPower = 0
            elseif (v.Character.Head.Position - player.Character.Head.Position).magnitude >15 then
                v.Character.Humanoid.WalkSpeed = 16

                if inp.KeyCode == Enum.KeyCode.P then
