@Mike

the original has the accelerometer so when you tip the phone back and forth the ship moves across the waves, and the jets randomly attack a do a loop D loop when they come down.
The Tutorials and code help a real lot. Thanks so much for all of your hard work. I about half way through T4. It looks great, just like the rest that you’ve done. I hope your family is feeling better, we all appreciate thye time and effort you put into this.

Yep, got it that time bob and its looking really good. I love seeing peoples ideas for games, I always seem to come up short when trying to think of an actual game idea rather than the mechanics :) I really like your game idea and the boat on the waves is a very nice touch.

I hope you enjoy Tutorial 4 and I’ll be getting Tutorial 5 up soon on Animation. I just need to make sure it all works with the changes I’ve made :)

@bob, sounds like things are really coming along :)

I’ve still not got your code though, I’m not sure why. I’ve checked my spam folders etc in case they were picking it up but nothing is in there. Just to check the email is mike @ 71squared . co . uk obviously without the spaces.

I am uploading the next Tutorial as I type so it will be up soon :)

HI Mike,

Thanks for the tip about image NULL… that will help in the future.

I sent the code a 3rd time hopefully you’ll see it tomorrow. I now have clouds moving, jets flying, ship moving, ocean waves and sound. Next is Accelerometer…
can’t wait till the next tutorial..

@Justin, I have also noticed that the Simulator can use up 100% of my machines processor. I think its just as the sim is hungry. When I run the same app on the iPhone is uses way less CPU. If you run instruments and take a look at the CPU you should see that overall the game is taking around 30% of the processor.

I am going to be making more changes to the main game loop which I’ll be posting on the blog soon, but I don’t think the current game loop would max out your iPhone.

Let me know if you have any other questions.

Excellent. I would have assumed that they would have both complained the same in that case!!

If you check the log output in Xcode and see the message

Image: null

That also means that a file passed into the Texture2D class could not be found or loaded and you know that its not been able to get the file you have passed in.

Not sure why but I didn’t get the code you sent over either…

Hi Mike,
I found the answer..

It seems the Simulator doesn’t care if you get the case wrong in when referencing image file names… (ie, “Rjet.png” should have been “RJet.png”), whereas the device does!!

Still waiting for you tutorial 4. And tonight i found that the mainGameLoop in your tutorial 3 code ran more than 90% cpu time of my machine when i ran it in my IPhone Simulator. Does it mean the line: while(CFRunLoopRunInMode(kCFRunLoopDefaultMode, 0, TRUE) == kCFRunLoopRunHandledSource); could not produce any delay for the loop? If I run that application in IPhone, will it run with all the cpu time too?

Thanks!

I can’t wait for the next tutorial!
Hope it’s as useful as the last ones

Thanks for all the help
