Ideally, I'd like to display a grid of rows and columns centered on the screen, but I'm not sure how. Here is my code: <pre><code>// Init the array NSMutableArray *itemArray = [[NSMutableArray alloc] initWithCapacity:kItemCount]; // Add an image for each menu item for (int i = 0; i < kItemCount; ++i) { CCMenuItemImage *item = [CCMenuItemImage itemFromNormalImage:@"someImage.png" selectedImage:@"someImage.png" target:self selector: @selector(doSomething:)]; [itemArray addObject:item]; } // Create the grid MenuGrid *newGrid = [MenuGrid menuWithArray: itemArray fillStyle: kMenuGridFillColumnsFirst itemLimit: kItemCount padding: padding]; // Position the grid and add it to layer newGrid setPosition:ccp(size.width/10,size.height/1.25)]; [self addChild:newGrid];</code></pre> Any help is greatly appreciated!

I have it working, except for the rotation to landscape, that only happens in the iPad sim. Also do you experience a long delay with the email fields being filled on the device? I am not using the pause layer, as I am using the email from my main menu anyway. It would be really nice to have it in landscape obviously, but the delay filling the fields is bothersome. shivaz on "I'm sharing some of my source code ..." http://www.cocos2d-iphone.org/forum/topic/4475#post-31869 Sun, 28 Mar 2010 14:13:51 +0000 shivaz 31869@http://www.cocos2d-iphone.org/forum/ For those who are interested in NSNotification - here is another quick post outlining my understanding and how I use it in my app. <a href="http://www.cocos2d-iphone.org/forum/topic/5334#post-31868" rel="nofollow">http://www.cocos2d-iphone.org/forum/topic/5334#post-31868</a> shivaz on "I'm sharing some of my source code ..." http://www.cocos2d-iphone.org/forum/topic/4475#post-31866 Sun, 28 Mar 2010 13:55:33 +0000 shivaz 31866@http://www.cocos2d-iphone.org/forum/ Okay, well I didn't get any response - but I have been asked if I did get it working, and if I could share. So for those who are struggling with joining the dots - here is what I have. Didn't quite go with above, though I am sure I used some of it, and I didn't quite go with stuff from other posts - though there were a few really good helps out there. Gathered a bit off Apple directly, and made some up. Maybe not the best way to do it - but maybe it will be helpful for some. Note, I have recently discovered the joys of NSNotification - and I am probably over using it - but it does make what I was trying to do here easier. If you have not seen them used - they are really worth it. Though I have not tested on a device yet - so I maybe completely disappointed with performance hit. Files: MailViewController.h/m EmailScene.h/m PauseMenuLayer.h/m MailViewController is required so that your UIViewController rotates to Landscape mode. Somehow I had this all working without doing that, but then when I came to submit my app - it stopped working! So after a bit of trial and error - this finally worked for me. <pre><code>// MailViewController.h #<a href='http://www.cocos2d-iphone.org/forum/tags/import'>import</a> <Foundation/Foundation.h> @interface MailViewController : UIViewController { } @end</code></pre> <pre><code>// MailViewController.m #<a href='http://www.cocos2d-iphone.org/forum/tags/import'>import</a> "MailViewController.h" @implementation MailViewController - (id) init { self = [super init]; return self; } - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; } @end</code></pre> EmailScene is the heart of the solution <pre><code>// EmailScene.h #<a href='http://www.cocos2d-iphone.org/forum/tags/import'>import</a> "cocos2d.h" #<a href='http://www.cocos2d-iphone.org/forum/tags/import'>import</a> <Foundation/Foundation.h> #<a href='http://www.cocos2d-iphone.org/forum/tags/import'>import</a> <UIKit/UIKit.h> #<a href='http://www.cocos2d-iphone.org/forum/tags/import'>import</a> <MessageUI/MessageUI.h> #<a href='http://www.cocos2d-iphone.org/forum/tags/import'>import</a> <MessageUI/MFMailComposeViewController.h> @class MailViewController; @interface EmailScene : CCScene <MFMailComposeViewControllerDelegate> { UILabel *message; MFMailComposeViewController *picker; UIImage *emailImage; MailViewController* emailController; } @property (nonatomic, retain) UILabel *message; @property (nonatomic, retain) UIImage *emailImage; -(void)displayComposerSheet; - (id) initWithImage:(UIImage *)myImage; @end</code></pre> <pre><code>// EmailScene.m #<a href='http://www.cocos2d-iphone.org/forum/tags/import'>import</a> "EmailScene.h" #<a href='http://www.cocos2d-iphone.org/forum/tags/import'>import</a> "MainMenuScene.h" #<a href='http://www.cocos2d-iphone.org/forum/tags/import'>import</a> "MailViewController.h" @implementation EmailScene @synthesize message,emailImage; - (id) init { self = [super init]; if (self != nil) { [self displayComposerSheet]; } return self; } - (id) initWithImage:(UIImage *)myImage { self = [super init]; if (self != nil) { self.emailImage = myImage; [self displayComposerSheet]; } return self; } // Displays an email composition interface inside the application.

I really want to get the sendMail stuff working - my only issue is that I am struggling to integrate it into my game. Can you give a quick outline how you would initialise it?

I can imagine having to manage a directory like that wouldn't be easy. Having a section on the wiki is a good idea, it Just needs the right people to be reading this so that they can add links to their stuff there. If you add a section, then I'll add some links to the stuff mentioned in the forum to get it started.

Actually cocos2d has one (/extras), and the problem with it is that it usually is outdated, and it can be difficult to understand the features of each class. I think it would be better to have a directory of 3rd party classes on the wiki. It is easier to maintain.

My only suggestion would be to include in the archive a copy of the webpage info as a README file, as it would be a nice summary to keep with the files. You could include the URL of your webpage in the readme as well so people will know where to check for possible updates/corrections in the future. Nice job and thanks for sharing.

Something like a "contrib" directory containing username directories with the contributed code. Lam's contributions would fit there nicely as well.

I give credit wherever possibly, if you think i missed to mention someone please let me know. Some of the code was found here, most was spread over the Internet. It took me time to collect and find the code and in some cases (eg In-App Mail) i put a lot of work into getting it right as well. I hope it'll be useful to many cocos2d developers. I also put up some useful links and will continue to add to this cocos2d iPhone resources page of mine as i learn more. At the time of this writing i'm sharing these classes/methods: AlertPrompt, CocoaHelper, LayoutHelper, LocaleHelper, MenuGrid, PlayMusicAction, Screenshot, SendMail, ShakeHelper, Utilities Read the webpage above to learn more about them.
