Moving a character depending on where it is facing.

I am working on a game where the user will go forward to wherever the “front” of the character is facing. I am completely new to game development, but I do have some experience with programming. I have also look for one elsewhere, but all of them use Rigidbody, and the character falls face first on the floor. Any help is appreciated.

Edit: It is a 3d game.

Well it really depends on what you’re looking for, is it a 2d game or 3d first to start off.
