This is a very simple idea, and one that’s useful for settings. You might have a settings screen, and your actual little game and they need to read from (the game) and write to (the settings screen) from an object they can both access. This simple concept took a lot of googling to find out [...]

For my first little play app, i built a little thing that had circles falling from the sky, and you could grab and toss them with speed based on the flick you applied. However I instituded my own “physics” for all the bouncing, because i couldn’t get cocos2d and box2d to work together. I noticed [...]

So i took a hiatus, I took a beautifully long trip to spain with my girlfriend. I’m back now, and I finally have an ipod touch to actually try to put things on. – I stumbled on cocos2d framework, and it’s really great. The way it’s structured is excellent, and if you’re coming from an [...]
