I need help. I’ve run into strange problems with a very simple cocos2d v0.99.4 project created from the cocos2d project template. It’s two scenes with a layer each, much like the regular HelloWorldScene layer. Each scene is simply supposed to replace itself with the other scene, on touch. What happens is that the first scene started with runWithScene is never deallocated after the first scene change. So it stays in memory and keeps receiving the touches, which means a touch is always behaving as if switching from the first to the second scene.
What’s more, if I add the onEnter and onEnterTransitionDidFinish methods to the first scene, without adding any code to them, the first scene/layer doesn’t receive any touch events at all. The second scene doesn’t show this behavior and works fine with these methods implemented.
Maybe I’m just overlooking the very obvious, if you could take a look and let me know if there’s anything I’m doing wrong with this code please let me know! Thank you.

I keep running into posts where users ask how fast cocos2d is, or why their particular code is slow.
I also tried to explain why the question of how fast cocos2d is has no real-world relevance.
Then i added a link to All-Seeing Interactive’s cocos2d Performance Tips as this is such a great post! It covers a lot of topics:
- Profiling with Instruments
- Testing on different devices
- Textures and Texture Atlases
- Speeding up loading times
- Reducing memory usage
- Flipping textures
- Pixel formats
- PVRTC (Texture Compression)
- Pre-render programatically generated textures
- Avoid using atomic accessors
- Read the best practices documentation
As always i hope you find these additions help- and useful.
