Hi Guys!

Firstly apologies for my poor proficiency level of english ^^
My name is Marc and i'm from Spain, since two weeks ago i'm trying to develope a little game with my friend Carlos.
This is our first game ever, indeed we have been surprised by the incredibly little steep learning curve of this amazing framework!
truly a spectacular job, congratulations Daniel.

Well, here my "problem":
When i try to get the stage width or height (self.width/height) in landscape orientation it returns the sizes of a portrait orientation. (i.e: self.width returns 320 in landscape mode :S)

Does anyone know how to solve this little problem?

Here is my code to change the orientation:
container = [[SPSprite alloc] init]; container.rotation = SP_D2R(90); container.x = 320; [self addChild:container]; ... [container release];
I've also added the code below into Info.plist:
```
<key>UIInterfaceOrientation</key>
<string>UIInterfaceOrientationLandscapeRight</string>
```

Each display object on the stage holds it's own coordinate system. So a rotated sprite will rotate it's axis, but the stage coordinates will always be in portrait mode, you can just use the width and height of container to get the correct landscape dimensions.

For example, if container is the first object you add to self, you can do something like this:
container = [[SPSprite alloc] init]; container.rotation = SP_D2R(90); container.x = 320; [self addChild:container]; float width = [self childAtIndex:0].width; float height = [self childAtIndex:0].height; [container release];
You can also find the child by name.

I'm not sure why you are releasing the container so soon if you're declaring it in the header (from the looks of it). I would suggest you release container in the dealloc method, and get the width and height like so:
float width = container.width; float height = container.height;
This way you can also add display objects directly to the container sprite, also.
Does that work for you?

Thanks Shilo! but it doesn't works.

When i get the container's width it returns 128 instead of 480 (its seems to fit depending on the width of his inner elements).

I've tried to change the width and height of the container manually (container.width/height) but neither works.

Any suggestions or ideas?

I need it for this particular case:
int width = container.width; int height = container.height; level.x = width - (level.width + 10); level.y = 10;

I completely overlooked that DisplayObjectContainer only holds the dimensions based on it's children's sizes and positions. If your going to end up setting the container's width and height manually, I think the best method would just be to add instance variables to the class header like so:
@interface Game : SPStage { float screenWidth; float screenHeight; }
Then in the init method just set them manually:
screenWidth = self.height; screenHeight = self.width;
Personally, I have a Screen class that does all the orientation handling and I set the width and height properties inside it manually.

Thank you Shilo!

The Screen class is a good solution
