How do you make a script that flings people?

I tried doing this but all I got was people sitting so I deleted the script and forgot it. :/

You will want to use bodyposition and vector3, here is an example to help you out

local b = Instance.new("BodyPosition")
        b.position = Vector3.new(500, 500, 500)
        b.maxForce = Vector3.new(500000000, 500000000, 500000000)
        b.Parent = character.Torso

Hope this helps!
