yeap, I’ve referred to the wiki and found it hard to comprehend. However, based on the tips you’ve offered, I reckoned that programmers only need to code with reference to their desired on-screen resolutions during the developmental process while cocos2d handles the scaling of game screen on devices based on the user-selected display policies.
I was having issues initially because I was learning to code with the sample test template that exhibited the capabilities of cocos2D. The problem was resolved once I’ve switched over to the MoonWarrior’s source codes and everything seems clearer. Great job on the well-written, concise codes. Maybe Zheng Jie should use this source code for learning too.
