local mouse = game.Players.LocalPlayer:GetMouse()

--mouse.Move:connect(function()
--  print(mouse.Hit.x)
--end)

mouse.Button1Up:connect(function()

        bullet.Velocity = (mouse.Hit.p-bullet.Position).unit*100
        bullet.CFrame = CFrame.new(game.Players.LocalPlayer.Character.AimPart.Position,mouse.Hit.p)
