How do i make a flashing part that moves?

The movement is basically an orbiting movement.

Most scripters do not like it when you ask them to make a script for you, hence the name script helpers. If you are looking for the legestics on how to make one, (not the actual script), then make sure to include that in you question. I would reccomend removing your question before your reputation is hurt even more. For starter scripts, start with a free model and edit it to you need. A good example is this "https://scriptinghelpers.org/questions/7987/make-a-gui-teleport-a-player" This person was polite enough not to ask for a script, but he got one anyways! Many scripters will be most helpful if you follow the guideline.
