I haven't been able to find the answer anywhere for this, so maybe someone can give me an idea of what to do or where to look. I am sorry if this question has already been addressed, but I have not seen the answer anywhere.

Question:
I know that the iPhone 4 can take lower res graphics and display them correctly automatically. I would like to create high res graphics for the iPhone 4, but by making higher res graphics the older iPhones will have a problem displaying the graphics, right? Will I have to create 2 sets of graphics for my games for now on?

Thank you!
Jason

Can anyone point me in the right direction?

Hi,
normally you would be able to use high res images and add @2x to their name and on a high res device (iPhone 4) those images would load automatically but there is a bug in the Apple SDK as Riq has mentioned. So you have to check manually if the device is high res or not. For example via the "scale". See this thread: http://www.cocos2d-iphone.org/forum/topic/7344#post-43037

Also check the release notes for 0.99.4 (search for "ISSUE 910"): http://www.cocos2d-iphone.org/wiki/doku.php/release_notes:0_99_4

@marcotronic So, if I check to see if the device is high res manually, and then set the scale factor manually will my higher res images automatically load with the @2x? Or, in other words how do I go about loading the high res set of images vs the normal res images if I determine which device I am on?

Thanks for your help!

After lots of research I still have the same question as above. Any ideas?

Although I haven't personally tried it yet, there's a discussion about this topic here:

Good luck. ;)

@Kitsune thanks for the info, but I am aware that the naming convention exists. I am also aware that there is a bug on Apples end that will not let the naming convention natively work with cocos2d. So that is why a lot of people are manually checking to see what device their app is running on. My question is that after you check which device your app is running on, how do I go about loading the specific images for either regular or high res?

@Enivid: I apologize for my ignorance on this topic. I haven't personally tried adjusting my graphics for hi-res yet so I was not aware of the issue. Hopefully someone else can provide more useful information. :)

@Kitsune no problem I appreciate the info though :). I will continue to look for the answer and if I find something out I will post it here. So maybe when you do decide to work on supporting high res and low res you can find some answers here. Hopefully someone can help point me in the right direction though.

Okay, so I have finally found the answer to my question!...it is cocos2d v0.99.5-beta3 or newer! v0.99.5 is in the third beta which introduced native high res support through a "-hd" suffix to the graphic files as well as a conversion to a point coordinate system versus the old pixel system. All the info for high res support is found here: http://www.cocos2d-iphone.org/wiki/doku.php/prog_guide:how_to_develop_retinadisplay_games_in_cocos2d

I hope this helps someone.
