You have to remember, Not everyone creates FPS games, so it’s right move to not have any kind of initial setup for player input/movement.
That being said, if you want to work on FPS projects without having to set those up manually, then don’t use blank project or mostof others. There is already two project templates for FPS that you can choose while creating a new project, so just use those.
There is also a Shooter game that you can download from marketplace, that gives you more features of an FPS from get go, though bases are C++.
