In response to your reply to the other commenter, I think it's unusual to share source code ( anywhere in tech, not just here ), for two reasons:
1. Exporting all that code would be difficult
2.Some people spend years learning their craft, and how to program functions, they might not see it as fair to give it away for free.
3. Beginner programmers ( especially self-taught ones ), probably don't have to best code to begin with.
If you want to learn to code, I recommend purchasing a book that will teach you your game engine, and/or watch some YouTube tutorials.
Follow Me , please btw. Trying to build a following! :)
