We used to host the videos for download but there are so many downloads now it was costing us a fortune in bandwidth charges, this is why we moved to Vimeo.

When new videos are added to Vimeo there is a download link available for a short while that can be used, apart from that we don’t have a download link available.

If we find a hosting solution that allows us to download the movies we will start that again. We were using over 40Gb per month on movies alone which can get expensive :o)

A link to the latest video for download is http://www.vimeo.com/8355746

The new template is set up to try and create an ES2 context that will only work on the SImulator of an iPhone 3Gs.  If that does not work then it will create an ES1.1 context using the ES1Renderer.

For my game I have simply removed the ES2Renderer all together and just use the ES1.1.

The code I have in EAGLView is below:

- (id) initWithCoder:(NSCoder*)coder
{
    if ((self = [super initWithCoder:coder]))
	{
        // Get the layer
        CAEAGLLayer *eaglLayer = (CAEAGLLayer *)self.layer;

        eaglLayer.opaque = TRUE;
        eaglLayer.drawableProperties = [NSDictionary dictionaryWithObjectsAndKeys:
                                        [NSNumber numberWithBool:FALSE],
					kEAGLDrawablePropertyRetainedBacking,
                                        kEAGLColorFormatRGB565,
					kEAGLDrawablePropertyColorFormat,
                                        nil];

		// Set up an OpenGL ES 1.1 renderer
		renderer = [[ES1Renderer alloc] init];

		// If the renderer is empty then something wen wrong so release this instance
		// and return nothing
        if (!renderer)
        {
            [self release];
            return nil;
        }
    }
    return self;
}

Hope it helps.

Hey, could you share the video in mp4 format, something like pod casts ?

I really want to watch tutorial videos on my iPhone, while I’m outside.

[playerShip drawAtPoint:CGPointMake(160, 240)];

Trying to debug I went to the Texture 2d file provided and I saw that the code exits at this line:

glVertexPointer(3, GL_FLOAT, 0, vertices);

Could you provide any insight as to what I might be doing wrong?

Thank you

Just to be clear, I’m recommending that you skip computing the angle and just store sinStickAngle and cosStickAngle which can be computed using dy/distance and dx/distance. This would eliminate *all* calls to atan2, cosf, and sinf, for the joystick. Then in your game logic just use the stored sinStickAngle and cosStickAngle. The joystick code does not need to call any trig functions.

But if you want to use trig, using atan2() as you do now is probably far less messy than computing the angle from distance and dy/dx because atan2 sorts out the correct angle quadrant for you.

Scoobie, I’m glad you sorted out your problem. The way the default template works is that it will try to create an OpenGL ES 2.0 context first and if this works then it will use that. If that fails it will try to create an ES 1.1 context. This is how you can build in support to your app for the different ES versions. On the Simulator it will allow you to create an ES 2.0 context and not drop into the 1.1 version. It will also do the same if you were running the code on an iPhone 3Gs or 4G iPod touch :o)

I hope you enjoy the rest of the tutorials.

Please disregard my last question. I finally found out my mistake in that I left #import ES2Renderer, so it was still calling that and overriding ES1Renderer? This is where I’m a little confused as I’m guessing the ES2 import is overriding the ES1 import. Nonetheless, I deleted the ES2 header and method and also any where else ES2Renderer would be called or checked and found that the your Tutorial 1 instructions work perfectly. It just took some time where to put some other code and what not.

I’m really enjoying it all though and look forward to spending more time catching up with your other tutorials.
