@mike, Washington, sorry for the huge delay in replying to your posts. I missed the emails telling me that comments had been made to this post.

mike, As long as the touch angle is in degrees and not radians, it should work OK. If you still have a problem or any code you can share I’ll take a look.

@Washington, I did cover orientation in the book and how I have done it for SLQ. That should give you what you need to get basic orientations supported. I may look at doing more on this in tutorials once the book is out.

@Nandini, with the joypad code, you could check to see what the players touch is on the joypad from the centre or the pad, breaking that into quandrants i.e. up, down, left and right means that with the touch in a defined quadrant, the players ship can be made to move up, down, left and right. I hope that makes some sense :o)

[...] ParticleDesigner. Excellent, clear tutorials. The joystick for my current game project was based on this tutorial and some other theory and code of my own [...]

Mike Thank you for these wonderfull tutorials, these are priceless my friend!
Here I have the Stanford University video courses but they don´t teach how to create a complete iphone game but you teach and with a good pratices in development.Tell me something…for the ipad is the same thing right? I just have to develop my game with the device dimensions.Also as I am still watching your videos ( I have discovered you yesterday ^_^ ) Do you comment on orientation rotation? like landscape right to landscape left or portrait right to portrait left? Because apple obligates us to do that. But I really don´t thing it´s necessary, but apple does. what do you think about making a tutorial to teach us about using xcode to compile our games to test or for distribution working with the provisioning keys( I know every app must have it´s own ID , it´s own provision key and our general certification but how to configure and generate for example an app to sell?

Hey Mike. I just wanted to say first that I love your website and what you do. This is by far the best site I have found for learning iPhone Game programming. I downloaded and commented SLQ, the final loks awesome. I really like the main menu screen. I can’t wait for your book.

I was hoping I could ask a question. Instead of changing the ships position, I want to change the ships rotation based on the angle in the joypad. I have tried using:

[player setRotation: touchAngle]

in the updateWithTouchLocationMoved method. I really though this would work. The ship does rotate a little bit left and right but only a couple degrees. Do you have any idea what I’m doing wrong?

Again. Thank you so much for all your time and effort.

Hey Mike
I have to say that this is by far the greatest blog out there for making an Iphone game!!! I’m a total beginner to Iphone programming, Objective C and OpenGl. And your blog has really helped me to make some sense of all these great and difficult things :)) I’ve been spending many mornings avidly watching all your videos besides studying for university.

Still I get really frustrated when I’m trying to do things on my own i.e. I was trying to insert the joypad example code to tutorial 9 and it just doesn’t work. There are no error messages but the joypad doesn’t show up on the screen ;-( I just don’t know how to link one thing to another. I think that you have to modify some code but I just don’t know what or where :D

Any help? Thanks!!!

Tommy

P.S. I can’t wait for your book ;)
