I originally posted this on cocos2d forum but I could not get any answer so I am re-posing this here and hopefully someone can help me out
This is weird - I have developed this game on my first machine and it was working fine. Then I migrated the code on my current Mac machine, it started to get angles all wrong (y in reversed direction etc). I have fixed the code finished development and tested on my iphone 4, everything was fine. So I submitted my app. Now I am testing it again on an iphone 3, the angles are all wrong again (the cordination are in the reverse)!!!
Has anyone came across this kind of problem before? Is there anything I have done wrong??
Do I have to use convertToGL, convertToUI or convertToWorldSpace to solve this problem?
What I do not understand is why it works on some devices but not the others ...
