I found the black lines appearing on screen, it seems to randomly happens whenever I move the camera (thus player) on screen. Please take a look at the attached image.
Anyway testing on simulator won’t have this problem.
Thanks Neel, it works ! I won’t see any performance drop so far.
I see the comment in that file as well stating that the “correct” way to fix this problem is to use spritesheet-artifact-fixer.py or other similar tools.
I then search and come across this link http://www.cocos2d-iphone.org/forum/topic/28041 which contains its sourcecode (i didn’t found it bundled with cocos2d-x). Anyway I think the latter solution is burden as you need to do the work twice, but did you ever try this solution ? (I hope it’s not about the texture downloaded from the tutorial from Ray’s website).
