How to animate the object?

I believe this would be a very basic question.

When I set the keys and press play for the Matineeactor, the object moves. However, when I turn off the Matineeactor and then go back to the main mode and press play, it is still stopped (the key setting is not applied). I would like to know how to then get the objective to move.

Hi!

You need to activate the Play function of your Matinee Actor like in this tutorial. If you want to immediately start the animation, then instead OnActorBeginOverlap you must create an Event BeginPlay.
