Hi Rolando, You shouldn't need to retain the objects as instance variables to keep them from premature garbage collection. In this case, I assume that the Cocos2D framework has been built with -fobjc-gc (otherwise you would get a link error at runtime), but that it's not fully compatible with the GC techniques yet. Passing the -fobjc-gc flag isn't enough sometimes, and one has to migrate the framework.
Some documentation is available here: http://developer.apple.com/library/mac/#documentation/cocoa/Conceptual/GarbageCollection/Introduction.html%23//apple_ref/doc/uid/TP30001223-CJBGIAGF Laurent On Jan 13, 2011, at 5:32 AM, Rolando Abarca wrote: > hi all, > > I'm having some fun with Cocos2D[1] Mac Version and MacRuby.
