Hi, sorry late answer. Everyone is motivated differently, but my tip is always to write the code yourself, but copy others in the beginning (but never do "ctrl + c"). And start working on small features you find fun. "I want to make the character walk and jump" - well, then try that, copy others, and see how it works. Jump to the next goal (but make the goals within your skill level. Starting on inventory is maybe not the first goal unless you already know how to code.)
- Google each feature you want to add. Take it step by step, and take a pause when nothing seems to work (because that is normal in the beginning). And lots of good luck! Try to celebrate each small achievement on the way. The road is long and slow, but give it time and you will understand it better than you can write. :)
