I was wondering if you could give an update on how to make the code work with retina displays. I’m googling for hours, feel like I did everything I should to (contentScaleFactor, correct renderbuffer dimensions, …), but the output still looks blurry. I do use @2x images, but it looks like the sprites are shrunk and then upscaled again. Any help on this would be great!!

Hey Mike, I was just wondering about saving game state. If I turn my iphone off, all the data is lost? It is only encoding/decoding ints and Bools rather than objects, and pressing the home button works fine for savng, but if i turn the phone off completely after doing this the loading isn’t taking place… any ideas?

Hi Mike great tuts, I jumped in on to chapter 12 to learn save game state, ran my code no errors but when the image postion is reset each time I delete App from multi-tasking. So I downloaded your source code and ran it (changed the iOS to 4.2) and it doesn’t save the rockets position? Is there something that needs adding for 4.2?

Cheers

Hi Guille

I’m glad the blog has been helping you. I’m hoping to post something over the next couple of days on using the high res graphics in OpenGL ES on the retina display, so watch this space :)

I’d really appreciate some retina display support explanation with openGL ES :D

Btw, I can’t describe how enlighted I felt when I firstly found out this tutorial series. I was seeing everything black, new language, new technologies, APIs etc.

Thanks Mike, not only for sharing your knowledge but also for doing it in such a time consuming, clean and successfull way from your side. From every video flows the energy you put on doing it.

Cheers
