Android game engine
This document discusses game engines for Android and provides recommendations. It explains that game engines help with faster and easier development by handling common tasks like rendering, physics, audio, etc. so developers can focus on the game. Several popular engines are described, including Rokon, Cocos2D and AndEngine. Each is evaluated based on features, performance and examples. The document recommends Cocos2D or AndEngine for new developers based on their capabilities and active communities.

- 1.
- 2. Agenda We Love Game Why need Game Engine What is Game Engine How many Game Engine Get one for You Implementation
- 3.
- 4. Do You LovePlaying Game? I DO
- 5. Everybody Love PlayingGame My Father plays Solitaire My Sister plays Labyrinth My Colleague plays AngryBird I play Dracula X, Super Mario III, Final Fantasy III, Tetris, Frozen Bubbles, ZooKeeper, Dragon Ball Z2 Z3, DDR...blah blah
- 6. Why Do WeLove a Game Art It looks awesome Story It is realistic Social We may make friends via game By exchanging information By sharing common experience Fun The most important part of a game
- 7.
- 8. Playing Game Everywhere FC MD,SFC SS, PS ....... NOW ? Long time ago we use GameBoy in toilet. Now we use mobile phone.
- 9. Why need GameEngine
- 10. Create a Game Everyonehas creativity We might want to clone a existing game We have a good idea for game Writing Game is COOL, and We are COOL!!
- 11. Game Engine helpsus Faster Developement Easier Developement You might don't know OpenGL... Abstract Layer You might need to port your game to another platform.... Focus on FUN If you spend more time on fighting with code, you has less time to think about your game, especially most of us are independent programmer.
- 12. What is GameEngine
- 13. Game Engine mighthas Sprite, Scene, Animation Renderer Modifier Physics Engine Particle System Collision Detection Event Handling Script Language Game Thread
- 14. Normal Android application AnActivity contains some Views. We interactive with some activities
- 15. In a Game AnActivity holds one GLSurfaceView. Game Engine switch one of scenes to display
- 16.
- 17.
- 18. How many GameEngine on Android
- 19. Lots of GameEngines If you search "android game" at Age Google Code, you will see lots Angle of game engines. Candroidengine Some of them are Graphics Catcake Engine Cloak Cocos2d Forget3d JMonkeyEngine ReplicaIsland Rokon AndEngine .........more
- 20. Target There are too many good game engines, I can only choose some of them. Rokon Cocos2D AndEngine Important: I believe there should be some great game engine but I missed
- 21. Rokon Rokon 2.0.3 http://rokonandroid.com/tutorials http://code.google.com/p/rokon/ Useful staffs Sprite, Modifier, Audio, Sprite Animation, Polygon Collision...blah You can see Particle System at Rokon 1, but nothing about Particle System at Rokon2 yet.
- 22.
- 23. Rokon images borrows fromReplica Island
- 24. Rokon Layer accepts GameObject. Youcan extends GameObject and create your own class then add to Layer
- 25. Rokon (touchable sprite) TextureAtlasatlas = new TextureAtlas(); Texture textureDoll = new Texture("doll.png"); Sprite mDoll; mDoll = new Sprite(X, Y, Width, Height); mDoll.setTexture(textureDoll); mDoll.setTouchable(); add(0, mDoll); @Override public void onTouchDown(Drawable object, float x, float y, MotionEvent event, int pointerCount, int pointerId) { if (object == mDoll) { android.util.Log.i("Hi", "touch down doll"); } }
- 26. Rokon (Audio) /* Longeraudio file */ RokonMusic.play("audio/music.mp3", true); //true means loop /* Shorter sound effects */ RokonAudio mAudio = new RokonAudio(); SoundFile mSound = mAudio.createSoundFile(sMenuTap); mSound.play();
- 27. Rokon(Animation) Sprite explosion =new Sprite(x, y, width, height); 1 Texture texture = new Texture("explosion.png", 5, 5) explosion.setTextureTile(texture, 25); // 25 is the lastest one /* tile 1 to tile 25, one frame spends 35ms, repeat once */ explosion.animate(1, 25, 35, 1, false); 25

- 29. Cocos2D Python Cocos2d → iPhoneCocos2d → Android Cocos2d http://code.google.com/p/cocos2d-android/ Android cocos2d matches version 0.8 of cocos2d for iPhone 0.9 is still in development
- 30.
- 31. Cocos2D CocosNode accepts Action Mostclasses extends CocosNode Sprite Label Scene Action rotate = RotateBy.action(2, 360); Sprite sprite = Sprite.sprite("ball.png"); Layer sprite.runAction(rotate); ColorLayer Menu MenuItem
- 32. Cocos2D 1. addChild: everyCocosNode may has child CocosNode 2. action: every CocosNode may has Action
- 33.
- 34. Cocos2D CocosNode + Action
- 35.
- 36. Cocos2D Some problems Particle SystemExample SceneTest Example Transition Example Particle System
- 37. AndEngine Fast Development http://www.andengine.org/ Extension Box2d Multiplayer MultiTouch ......etc Amazing examples http://code.google.com/p/andengineexamples/ You can download the example at Market.

- 39. AndEngine(Camera) See Example TMXTiledMapExample setChaseShape(IShape);
- 40.
- 41. AndEngine Touch and MultiTouch Custom Font

- 44. Replica Island Well designedgame Open Source http://replicaisland.net/ It is very possible to split engine from the game http://code.google.com/events/io/2009/sessions/WritingReal TimeGamesAndroid.html (it is worth reading) Mailing list https://groups.google.com/group/replica-island-coding- community/topics Highly activity!!
