I've just got an idea to make a parkour game with bodycam style pov. But to me, a person with no experience in coding I don't know what kinds of things I should learn to even begin tackling this idea. Do I start with the basics? Or cut some corners and skip a few steps?

For context: I'm a complete beginner and I know making a sword is probably VERY unrealistic for my skill, but I'd still like to try. Also I have absolutely no tools at all.
