game works on iphone4 but not itouch4??

patm1982

Wondering if anybody else has come across this. It was tested on iphone4, ipod2 & ipad1. works on all, but crashes when entering the first level (a few scenes in) on itouch4.

any ideas? and if it works on older devises it can't be a performance issue...

Perhaps a memory issue? What format are you doing for the game? If you are using retina graphics it might be that as the 4th gen itouch has retina and if you were using that format, that on earlier devices the engine would select the low res graphics, on the iphone4 you might be getting retina display graphics with the memory just under the limit but with the 4th gen itouch you are hitting the limit... This is only speculation on my part as I am not sure of the comparative available. Perhaps though it might be worth looking into (if you are using retina graphics).

Bingo.

The iPod touch 4th gen has only 256mb Ram whereas the iPhone 4 has 512mb. Both these devices will request the retina graphics. Where as the iPads will only pull the standard resolution images and not max out the Ram.

To test this close GS and make a copy of your gameproj file. In the copy show the package contents and open the images folder. Load them all in bulk into preview and resize them all down by 50%. Save and relaunch the new gameproj file in gamesalad. Test on the iPod touch 4th gen and see if it works.

Not that this is a solution as it will crap up the resolution of all your graphics, but it will prove if this is the issue and you can set about removing/reducing resolution of images.

interesting, I assumed they both had the same RAM specs. Sure enough I confirmed what you said on the internet. 256 vs 512

Lame on Apples part. but a pretty easy fix.

thanks
