  1. Code Review : Pong Clone

    Thank you for your reply! ^.^ This actually gives me a lot to think about. I'm a very new coder and I'm still just learning and not only have you taught me something new, you might just have helped me understand some things that I hadn't even thought of trying to understand. Implementing the scenes in that way actually helps me in another way which I will reveal later if I can work it out, lol. I'm so gonna refactor this thing.   Thank you, once again!
  2. Code Review : Pong Clone

    Pretty self-explanatory, really I followed the advice I got here and coded a Pong clone. I had some knowledge of Java and thus decided to go with Processing. This is the completed game's code. Please guide me on understanding everything that's wrong with it, because I know there must be plenty. Thank you.   Here's a link where you can play the game: http://www.openprocessing.org/sketch/103532 int MODE; MenuText back; /* @pjs font="Arial.ttf"; */ PFont titleF; PFont menuItemF; String[] menuItemsNames={"START","INSTRUCTIONS","CREDITS"};  //Creates the array that will be passed to the Menu class for forming individual MenuText objects.

  3. How to start game programming?

    I don't know if I should be speaking here since I am a complete newbie not only to game programming but to programming in general. I have some coding knowledge(though only in Java) but very little experience. Still, I read the beginner's article here and started teaching myself. Since I know a bit of Java, I picked the Processing language to work with and started coding Pong. And finished coding Pong :) And have now moved on to Snake. And am stuck there.   But my point is. I'm learning a LOT just by trying to figure these things out. Seriously, I'm learning just by doing it.   So my suggestion is....whatever it is you plan to do...just make a beginning. Start simple, keep moving up and keep moving forward.   Cheers :)
