Hello everybody! Just want to share with you some code, that i used while developing iTraceur. There are: https://github.com/psineur/FilesDownloader - Downloads group of files from direct links, includes example and super class for your downloading screen (Using Cocos2D) https://github.com/psineur/CCVideoPlayer - Universal Mac/iOS video player for Cocos2D, that can be easily modified to work without Cocos2D. https://github.com/psineur/DynamicTiledLevelNode - CCNode subclass, that allows iTraceur to have huge levels (i.e. street is 16000x2500 points) Can be used for building levels with any size. https://github.com/psineur/CCMenuAdvanced - CCMenu that allows me to develop universal resolution independent Mac/iPad/iPhone/Retina menus and screens. Blogpost about how to develop such menus/screens: http://parkourdev.blogspot.com/2011/04/universal-macios-menus-with-cocos2d.html All these repos includes examples, that illustrates how to use that stuff. Also note the commit history, which also can be a good guide. Follow me on the GitHub for more: https://github.com/psineur & feel free to ask for any features, that you would like to see in these repos, or something else from iTraceur. I will try to find time to help you. As an additional demonstration there's iTraceur for iOS: http://itunes.apple.com/us/app/itraceur-parkour-freerunning/id374163905?mt=8 and for Mac: http://itunes.apple.com/us/app/itraceur-parkour-freerunning/id417629805?mt=12 Both game shares the same code, thankfully to Cocos2D! If you'd like to contribute, you can buy iTraceur, retweet this tweet: https://twitter.com/#!/parkourdev/status/60809112556023808 or just tell anyone about my game. I will really appreciate this!
