How to loop an animated character ?


First of all, I apologize for english mistakes I could make.

I’m studying art and I’m trying to do a game on my own. Actually, I’d like to experiment a game where you can’t die, where you just have to walk around. It would be about ambient.
To do so, I’m just getting started on UE4, and I have a question about the animation of a simple body.

I’d like a character who could walk infinitely in circle around the map. It does not have to react to anything, the only goal of this character is to walk for ever. It doesn’t need collision, I want the player to be able to go through that walking character.

I guess it’s super easy to do, but I don’t now where to begin…

Thanks for you help,
