can someone please explain to me how moving objects are produced ? (example in games). must I use graphics.h?. how do I transform it from simply a compiled piece of code in code block to a real software?. I've been googling this for days now and I'm still confused. Please an extensive explanation would be appreciated🙏. Thanks. p. s you can also recommend websites where I can learn more and see good sample codes.
