Simply trying to test retina display. I setup the director like this:
CCDirectorIOS* director = (CCDirectorIOS*)[CCDirector sharedDirector];
director.wantsFullScreenLayout = NO;
director.projection = kCCDirectorProjection2D;
director.animationInterval = 1.0 / 60.0;
director.displayStats = YES;
[director enableRetinaDisplay:YES];
I create two versions of the file in Photoshop - outline-hd.png and outline.png. I color the HD version red so I can tell if it's being displayed.
Display code:
CCSprite *border = [CCSprite spriteWithFile:#"outline.png"];
[self addChild:border];
Yet it is the non-hd image that gets displayed on my iPhone5. Why?
I came across this question while trying to solve the exact same problem in my own project. Had to dig around in the cocos2d source to figure it out. The problem is that the director's enableRetinaDisplay:YES method doesn't work unless the director's view is set. So, it needs to be called after the glView is set up, and you've called setView on the director:
CCGLView *glView = [CCGLView viewWithFrame:aFrame
pixelFormat:kEAGLColorFormatRGBA8
depthFormat:0
preserveBackbuffer:NO
sharegroup:nil
multiSampling:NO
numberOfSamples:0];
[[CCDirector sharedDirector] setView:glView];
NSLog(#"glView is set, enable retina...");
[[CCDirector sharedDirector] enableRetinaDisplay:YES];
This should fix the problem for you!
May be you forgot:
CCFileUtils *sharedFileUtils = [CCFileUtils sharedFileUtils];
[sharedFileUtils setEnableFallbackSuffixes:NO];
[sharedFileUtils setiPhoneRetinaDisplaySuffix:#"-hd"];

Can someone explain to me how cocos2d uses png as a font?
I would like to do something similar as my font only contains numbers.
if you do a global search on the string fps_images.png , your IDE should take you real close to the following lines in cocos CCDirector class (version 2.0) :
FPSLabel_ = [[CCLabelAtlas alloc] initWithString:#"00.0" charMapFile:#"fps_images.png" itemWidth:12 itemHeight:32 startCharMap:'.'];
SPFLabel_ = [[CCLabelAtlas alloc] initWithString:#"0.000" charMapFile:#"fps_images.png" itemWidth:12 itemHeight:32 startCharMap:'.'];
drawsLabel_ = [[CCLabelAtlas alloc] initWithString:#"000" charMapFile:#"fps_images.png" itemWidth:12 itemHeight:32 startCharMap:'.'];
then look up CCLabelAtlas. Your image must be for a fixed width font.
If you want to reuse the same image included to make something other than the FPS display the following code should work:
CCLabelAtlas *scoreLabel = [[CCLabelAtlas alloc] initWithString:#"00.0" charMapFile:#"fps_images.png" itemWidth:12 itemHeight:32 startCharMap:'.'];
Then to set it to the numbers you want something like this works:
[scoreLabel setString:[NSString stringWithFormat:#"%d", (int)score]];
I have been working for an iPad game using Cocos2d 2.0, I am facing a problem while loading HD images for the new iPad (Retina Display). But I can't figure out why HD images are not being loaded automatically while executing the code:
Even after adding [director enableRetinaDisplay:YES]; it is still not working. Here is the code sample of when loading image :
MainBG = [CCSprite spriteWithFile:#"menuBackground-ipad.png"];
CGSize ScreenSize = [[CCDirector sharedDirector]winSize];
MainBG.position = ccp(ScreenSize.height/2,ScreenSize.width/2);
[self addChild:MainBG z:0];
I have another image menuBackground-ipadhd.png in the project resources (I can see it from Xcode as well).
Anyone can help ?
For me it is working in cocos2D 2.0
Change that menuBackground-ipad.png to menuBackground.png
Make sure all these lines r found in ur appDelegate and pushScene at the end. Also use onEnter instead of init in layer class.
if( ! [director_ enableRetinaDisplay:YES] )
{
CCLOG(#"Retina Display Not supported");
}
CCFileUtils *sharedFileUtils = [CCFileUtils sharedFileUtils];
[sharedFileUtils setEnableFallbackSuffixes:NO]; // Default: NO. No fallback suffixes are going to be used
[sharedFileUtils setiPhoneRetinaDisplaySuffix:#"-hd"]; // Default on iPhone RetinaDisplay is "-hd"
[sharedFileUtils setiPadSuffix:#"-ipad"]; // Default on iPad is "ipad"
[sharedFileUtils setiPadRetinaDisplaySuffix:#"-ipadhd"]; // Default on iPad RetinaDisplay is "-ipadhd"
[director_ pushScene: [IntroLayer scene]];
//In Layer..
-(void)onEnter
{
[super onEnter];
MainBG = [CCSprite spriteWithFile:#"menuBackground.png"];
CGSize ScreenSize = [[CCDirector sharedDirector]winSize];
MainBG.position = ccp(ScreenSize.height/2,ScreenSize.width/2);
[self addChild:MainBG z:0];
}
Do not specify the ipad/hd/etc file suffix when loading files. Your problem is caused by using the -ipad suffix here:
MainBG = [CCSprite spriteWithFile:#"menuBackground-ipad.png"];
Remove the suffix to allow cocos2d's do it's job in selecting the correct image:
MainBG = [CCSprite spriteWithFile:#"menuBackground.png"];
after few headaches i figured out that using CCSpriteBatchNode with cocos2d olny allows to z-order sprites added to it as child (which is obvious, now i see..)
[[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile:#"token_default.plist"];
CCSpriteBatchNode *tokenSpriteSheet = [CCSpriteBatchNode batchNodeWithFile:#"token_default.png"];
[[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile:#"objects_default.plist"];
CCSpriteBatchNode *objectsSpriteSheet = [CCSpriteBatchNode batchNodeWithFile:#"objects_default.png"];
CCSprite *token = [[[CCSprite alloc] initWithSpriteFrameName:#"token_SE.png"] autorelease];
[token setPosition:tokenSpawnPoint];
CCSprite *enemy = [[[CCSprite alloc] initWithSpriteFrameName:#"token_blak_SE.png"] autorelease];
[enemy setPosition:enemySpawnPoint];
CCSprite *houseA = [[[CCSprite alloc] initWithSpriteFrameName:#"house_small.png"] autorelease];
[houseA setPosition:[self randomHousePosition]];
CCSprite *houseB = [[[CCSprite alloc] initWithSpriteFrameName:#"house_big.png"] autorelease];
[houseB setPosition:[self randomHousePosition]];
[tokenSpriteSheet addChild:token];
[tokenSpriteSheet addChild:enemy];
[objectsSpriteSheet addChild:houseA];
[objectsSpriteSheet addChild:houseB];
and since i have to add them to the display list as follows..
[_isoMap addChild:objectsSpriteSheet];
[_isoMap addChild:tokenSpriteSheet];
there is no way i can change the z-order of single tokens between other houses...
they will be always rendered over the house until i change the order of these batch nodes
btw, i can "merge" all sprites' arts in one big single batch node... doing so it became possible to order sprites using sprite's coordinates
[fullSpriteSheet reorderChild:token z:token.position.y];
i'm a little stuck with it...... is there a way to achieve that, having different sprite bacth nodes? or is possible to programmatically merge two batchnodes? (or something like that)
i found KnightFight, a really interesting open project on github by LozArcher.. he used CCSpriteFrame and CCSprite's setDisplayFrame method, instead of batch nodes... but i can't run it since it seems to be an older version of cocos2d (apparently not working with xcode 4)
i found out that changing the vertexZ property of a CCNode (like a CCSprite) it actually changes its Z position (so it will be slightly bigger/smaller, and also translated)
so, in order to arrange on z-index CCSprites with different spriteSheet i had to use reorderChild method (to just change the rendering order) and mostly i need NOT TO USE CCSpriteBatchNode..
after a little refactoring of the above example, i should have:
CCSprite *token = [CCSprite spriteWithSpriteFrameName:#"token_SE.png"];
[token setPosition:tokenSpawnPoint];
CCSprite *enemy = [CCSprite spriteWithSpriteFrameName:#"token_blak_SE.png"];
[enemy setPosition:enemySpawnPoint];
CCSprite *houseA = [CCSprite spriteWithSpriteFrameName:#"house_small.png"];
[houseA setPosition:[self randomHousePosition]];
CCSprite *houseB = [CCSprite spriteWithSpriteFrameName:#"house_big.png"];
[houseB setPosition:[self randomHousePosition]];
[_isoMap addChild:token];
[_isoMap addChild:enemy];
[_isoMap addChild:houseA];
[_isoMap addChild:houseB];
i also added each sprite to a NSMutableArray
and then in a for loop (inside the update scheduled method):
CCSprite *sprite = [mySpritesArray objectAtIndex:i];
[_isoMap reorderChild:sprite z:(_isoMap.mapSize.height - sprite.y)];
hope this could help someone :)
I still think that is not better solution,
if your objects on map are moving dynamically, you can still stuck in z order issues.
I know its very old post, and people keep coming here by google search,
so I am posting solution here.
float lowestZ = tilemap.map.width +tilemap.map.height ;
float currentZ = self.gridLocation.x + self.gridLocation.y ;
int zOrderDecided = lowestZ + currentZ - 1 ;
[self.parent reorderChild:self z:zOrderDecided];
Set the Sprites Z order to it's Y position on the map. Reorder your dynamic sprites in an update loop. Calculate the Z order using the Sprites current Y position and the visible height of the map.
void LocalGameController::SetZOrderForObject(cocos2d::Sprite *object){
int objectZOrder = visibleSize.height - object->getPositionY();
context->reorderChild(object, objectZOrder);
}
I initialize my CCLayer using the following init code:
- (id)init {
if((self=[super init])) {
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
picker.wantsFullScreenLayout = YES;
picker.allowsEditing = NO;
picker.showsCameraControls = NO;
picker.navigationBarHidden = YES;
picker.toolbarHidden = YES;
picker.cameraViewTransform= CGAffineTransformMakeScale(1.3, 1.33);
[[[CCDirector sharedDirector] openGLView] addSubview:picker.view];
CCSprite *gold = [CCSprite sprite];
gold.position = ccp(150, 150);
[self addChild:gold];
}
return self;
}
The CCSprite was above the camera view before the camera shutter opens, but when the shutter opens, the CCSprite is overlapped by the camera.
Can I rearrange the order of these 2 objects / put the camera view to the back ?
Not without some extra work.
To understand this you have to consider that you're adding the camera view to the openGLView by Cocos2D. This makes the camera view a "child" view of the Cocos2D view. This is similar to adding a child node to a CCScene or CCLayer, and then wanting to have that node drawn behind the scene or layer. You can't do this without changing the way the view hierarchy is setup.
So you will have to modify Cocos2D's startup so that the openGLView is not added to the UIWindow directly, but to another UIView.
UIView* dummyView = [[UIView alloc] initWithFrame:[window bounds]];
[dummyView autorelease];
[dummyView addSubview:[CCDirector sharedDirector].openGLView];
rootViewController.view = dummyView;
You can then add the camera view to the dummyView (not the openGLView or you'll have the same problem as before) and perform sendSubviewToBack on it so that it is in the background.
You will also have to initialize the OpenGL view of Cocos2D with kEAGLColorFormatRGBA8 pixelFormat in order to provide an alpha channel.
EAGLView* glView = [EAGLView viewWithFrame:[window bounds]
pixelFormat:kEAGLColorFormatRGBA8
depthFormat:0
preserveBackbuffer:NO
sharegroup:nil
multiSampling:NO
numberOfSamples:0];
You also need to make the openGLView transparent:
[CCDirector sharedDirector].openGLView.opaque = NO;
Of course this only works if you don't render anything fullscreen on the cocos2d view. For example, if you provide a fullscreen background image for your Cocos2D view, nothing will show up because the background image is rendered on top of the camera view.
You can find a more detailed explanation in the second edition of my book. You can also download the book's source code from that link and see the examples of chapter 15. Or download Kobold2D and use the provided Cocos2D-With-UIKit-Views template project.
I am creating a game of questions and answers for iphone using cocos2d, and I wonder how can I do to display the question on the screen using ccLabel seeking data from a plist. can someone help me with this!
What you want to do is grab it from your resources bundle, and save it into a dictionary. From there you have access to every value inside of your plist. That can be achieved with something like this:
NSString *path = [[NSBundle mainBundle] bundlePath];
NSString *finalPath = [path stringByAppendingPathComponent:#"myList.plist"];
NSDictionary *plistData = [[NSDictionary dictionaryWithContentsOfFile:finalPath] retain];
Then when you're ready to display the question just use the [plistData objectForKey: ] method. Do you need help setting up the label also?
Sure man. You want to set it up like this:
CCLabel* questionLabel = [CCLabel labelWithString:#"Your Question"
fontName:#"Marker Felt" fontSize:64];
CGSize size = [[CCDirector sharedDirector] winSize];
label.position = ccp( size.width /2 , size.height/2 );
[self addChild: questionLabel];
That'll display your label in the middle of the screen. You can change the position, font, etc. The way you access your data from the plist is determined by exactly how you set it up. But using the technique I gave your earlier you shouldn't have a problem.
