how to create your own game engine with java

If you're interested in the knowledge, I do encourage you to spend some time building a very basic game from scratch for the sake of learning. With that being said, there are cases where doing things from scratch can be beneficial, imo the following list illustrates that:

If you decide to do things from scratch, it will take you a whole lot longer to make something significant, and that is assuming you have enough skills and experience. Game engines can make your life a whole lot easier and help you create significant things in much shorter time. The reason why you should not avoid engines is the same reason why you should not build your own fishing rod when you go fishing, I mean it's cool if you can build one from scratch but you don't need to re-invent the wheel when there are tools available. If you want to create games and release them for others to play and enjoy, DO NOT AVOID GAME ENGINES. I guess a better question is, what are your intentions for building a game from scratch? This is often asked by beginners, and let me give you an advice that I could have gotten 7 years ago (Which I didn't unfortunately).
