How do I change this from using magnitude, to using GetPartsInPart? I need the Add functions to work when inside the part, and the remove after you exit the part.

if ID.Value == 0 then
	ID.Value = math.random(5000,10000)
    PG.Value = ID.Value
end

	if Gravity.Value == PG.Value and plr:DistanceFromCharacter(part.Position) > Radius  then
		Gravity:Destroy()
