How to do it?

There’s a moving train where the objects do not move.
How do I transfer to the train movement of objects.

Maybe AttachToActor ?

Hi Farkas1212 could you provide a little more information as to what you are trying to achieve? Are you asking how do you make a train move? There are a few ways you can do that; however I find that using matinee is a very easy way to achieve this goal. Perhaps this video will help you: - YouTube
