<p>Hello,</p> <p>I want to store a high score list for my game on a central server so people can see how well they are doing compared to other people.</p> <p>I really want to avoid people being able to jail-break their phones and edit their scores, or scan the ip traffic to send fake scores to the server.</p> <p>From what I understand Apple don't really like encryption being used in the apps, and it increases the chances of the app being rejected.</p> <p>Whats the best way to deal with this situation?</p> <p>Thanks</p>

<p>Hi all, How can I change an image position like background-position in css? By position I don't mean the position of background like ccp(200,150), I mean for example, I have an image with resolution of (1000,200) that contains 5 (200,200) images. I show this image in (200,200) sprite and I want to change the image position so I can show 5 pictures in 1 picture. I think If you want to show a movement like running, you use sprites with like 10 frames of movement and change the picture position so it looks like a person is running. How can I do that? thanx in advance</p>

<p>I've been working on a relatively simple iPhone game for about six months. It uses OpenGL ES and the SoundEngine/EAGLview from the CrashLanding sample code. Also note I'm still using iPhone OS 2.0.</p> <p>I've noticed a strange behavior... the game will crash after using the google maps app that comes w/ the phone. So after using the map's gps feature, searching for some things, getting directions etc the game will crash immediately upon launch. It doesn't crash at all otherwise. Restarting the phone fixes this problem.</p> <p>What would you do in this situation? Have you encountered problems like this? Could OS 2.0 vs 3.0 make a difference?</p>

<p>Alright, I'll bite the negative bullet: What's the point of iPhoneGameDev when there's a perfectly good and well-frequented StackOverflow? If you're only interested in iPhone dev, then just use the appropriate tags to filter down the traffic, e.g.: <a href="http://stackoverflow.com/questions/tagged/iphone" rel="nofollow">http://stackoverflow.com/questions/tagged/iphone</a></p> <p>In other words, I'd like to know what this particular site would bring when I'm already following SO. There may be genuine things that would not work on SO (that's what I'd like to see first in your answers). But from the questions I see so far, the majority of them would perfectly fit on SO and get quick and relevant answers.</p>
