How to enable collision with Part and Effect

Me need checking on Effect.Touched and launching the my func.
How make it? (Effect.Touched:Connect(myfuncdmg)) – this is a example

Im solved this problem, to whom need: Just create the big part (radius) and set your effect, then - create the disabled local script or script to manipulate position of the part, then - just check the Touched event with enabling script
