So, the question seems vague but I will elaborate.
I’m a software developer, but I don’t do games; yet I have an urge to try and make something.
It just seems so overwhelming, I know I want to make a game where the main character is a cat and you have to complete missions, but where do you even begin. Where does the art come from? How do you refine your idea, if all you know is you want a cat game? How do you choose an engine? Do you just start with the basics and get a cat walking around and see what comes next? If you can’t hash out the idea then so you have a right to even try and make a game? Is it best to follow tutorials to get used to making games? I feel the answer to that is no as before I become a software developer, tutorial hell was a thing and I realised I needed to make things for me to actually learn.
Sorry for all the questions, this was just a stream of thought.
How? Blood, sweat and tears mostly.
Usually it’s recommended not to start with your “dream game”. Pick an engine (I like Godot), grab some Kenney art assets, and get to work on a pong or snake clone. This can be using written tutorials, videos, or hard mode, read the docs and piece it together.
Trying to learn a language, learn an engine, learn the art pipeline, learn game dev concepts AND dream up a new game concept with custom assets simultaneously is trying to boil the ocean. Start small: add a start menu, add a scene. Make jpg appear and move using player input, add an obstacle, add a death scene/restart. Iterate from there.
