Need help with game element in unity c#, can you help?

Question

C++ / C#

It is necessary that the walls in the game, in a 2D style, go to the character, then they are removed and put back in front, so that the walls go endlessly and not the character along the walls. It is necessary that the character itself remains in place.

Answer 1

Unity uses 3d for all cases (and for 2d too), then think for yourself

Answer 2

Usually this is done by tiling (the origin) of the texture in the material, and physically nothing is moved at all.
