I'm trying to add a background image for my scene using the following code:
CCSprite* background = [CCSprite spriteWithFile:#"background-hd.png"];
background.tag = 1;
background.anchorPoint = CGPointMake(0,0);
[self addChild:background];
My apps orientation is landscape and the image's orientation is landscape as well, however I get the image orientated in portrait:
I think this is the solution with Layer which set the scene with orientation...
+(CCScene *) scene
{
CCScene *scene = [CCScene node];
StartLayer *layer = [StartLayer node];
CCSprite *background = [CCSprite spriteWithFile:#"background-hd.png"];
background.anchorPoint = ccp(0,0);
[layer addChild:background z:-1];
[scene addChild: layer];
return scene;
}
See this link for More information Cocos2d-Scenes-and-Layers....
Hope this helpful to you...

I have a an app using cocos2D for a mini-game.
When I push a button, I launch a cocos2D scene with the game.
I try to load just a image in background (bg.png) in my cocos2D scene. I'm using sprites.
It works on iPhone 5 and iPhone 4S (iOS 6), but it doesn't work on the iPhone 4.
On the iPhone 4 I have a black screen. I don't understand why.
sprites-hd.png does 3762 × 1252, 1,4 Mo. Is it too big for the iPhone 4 ?
In my GameViewController_iPhone.m :
-(IBAction) playGame {
CCDirector *director = [CCDirector sharedDirector];
CCGLView *glView = [CCGLView viewWithFrame:[[ISAMAppDelegate_iPhone sharedISAMAppDelegate].window bounds]
pixelFormat:kEAGLColorFormatRGB565 // kEAGLColorFormatRGBA8
depthFormat:0 // GL_DEPTH_COMPONENT16_OES
];
// attach the openglView to the director
[director setView:glView];
if( ! [director enableRetinaDisplay:YES] )
MyLog(#"Retina Display Not supported");
[[CCDirector sharedDirector] setAnimationInterval:1.0/60];
[CCTexture2D setDefaultAlphaPixelFormat:kCCTexture2DPixelFormat_RGBA8888];
[self.view addSubview:glView];
[[CCDirector sharedDirector] runWithScene:[Game sceneWithGameViewController:self]];
}
In my Game.m :
+ (CCScene *)sceneWithGameViewController:(GameViewController_iPhone*) gvc
{
CCScene *game = [CCScene node];
Game *layer = [[Game alloc] initWithGameViewController:gvc];
[game addChild:layer];
return game;
}
- (id) initWithGameViewController:(GameViewController_iPhone*) gvc {
if(![super init]) return nil;
if((self = [super init])) {
[[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile:#"sprites.plist"];
CCSpriteBatchNode* batchNode = [CCSpriteBatchNode batchNodeWithFile:#"sprites.png" capacity:50];
[self addChild:batchNode];
CCSprite *someSprite = [CCSprite spriteWithSpriteFrameName:#"bg.png"];
[batchNode addChild:someSprite];
}
}
You can't load textures larger than 2048x2048 in iPhone 4, so you may split your current sprite atlas.
I want to integrate cocos2d in one of my view. So, I have a normal view controller(MapEditorViewController) and a view, in my view controller, (I created a IBOutlet UIView *openGLView) in which I want cocos2d to be in. In my view controller, I have a method setupCocos2D :
- (void)setupCocos2D {
CCGLView *glView = [CCGLView viewWithFrame:self.openGLView.bounds
pixelFormat:kEAGLColorFormatRGB565 // kEAGLColorFormatRGBA8
depthFormat:0 // GL_DEPTH_COMPONENT16_OES
];
glView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
[self.openGLView insertSubview:glView atIndex:0];
[[CCDirector sharedDirector] setOpenGLView:glView];
CCScene *scene = [HelloWorldLayer scene];
[[CCDirector sharedDirector] runWithScene:scene];
}
setupCocos2D is called in viewDidLoad of the class MapEditorViewController.
I have a layer (HelloWorldLayer), which is basically the code in the tutorial of http://www.raywenderlich.com/25736/how-to-make-a-simple-iphone-game-with-cocos2d-2-x-tutorial
// Helper class method that creates a Scene with the HelloWorldLayer as the only child.
+(CCScene *) scene
{
// 'scene' is an autorelease object.
CCScene *scene = [CCScene node];
// 'layer' is an autorelease object.
HelloWorldLayer *layer = [HelloWorldLayer node];
// add layer as a child to scene
[scene addChild: layer];
// return the scene
return scene;
}
- (void) addMonster {
CCSprite * monster = [CCSprite spriteWithFile:#"backbutton.png"];
// Determine where to spawn the monster along the Y axis
CGSize winSize = [CCDirector sharedDirector].winSize;
int minY = monster.contentSize.height / 2;
int maxY = winSize.height - monster.contentSize.height/2;
int rangeY = maxY - minY;
int actualY = (arc4random() % rangeY) + minY;
// Create the monster slightly off-screen along the right edge,
// and along a random position along the Y axis as calculated above
monster.position = ccp(winSize.width + monster.contentSize.width/2, actualY);
[self addChild:monster];
// Determine speed of the monster
int minDuration = 2.0;
int maxDuration = 4.0;
int rangeDuration = maxDuration - minDuration;
int actualDuration = (arc4random() % rangeDuration) + minDuration;
// Create the actions
CCMoveTo * actionMove = [CCMoveTo actionWithDuration:actualDuration
position:ccp(-monster.contentSize.width/2, actualY)];
CCCallBlockN * actionMoveDone = [CCCallBlockN actionWithBlock:^(CCNode *node) {
[node removeFromParentAndCleanup:YES];
}];
[monster runAction:[CCSequence actions:actionMove, actionMoveDone, nil]];
}
// on "init" you need to initialize your instance
-(id) init
{
// always call "super" init
// Apple recommends to re-assign "self" with the "super's" return value
if( (self=[super initWithColor:ccc4(255,0,255,255)]) ) {
CGSize winSize = [CCDirector sharedDirector].winSize;
CCSprite *player = [CCSprite spriteWithFile:#"carteIntrouvable.png"];
player.position = ccp(player.contentSize.width/2, winSize.height/2);
[self addChild:player];
[self setIsTouchEnabled:YES];
[self schedule:#selector(gameLogic:) interval:1.0];
}
return self;
}
-(void)gameLogic:(ccTime)dt {
[self addMonster];
}
Now, I don't know what I'm doing wrong, the layer appears but it is black, even though I change the line initWithColor in -(id) init.
How can I change the layer's background color, because the code works if I don't integrate cocos2d with UIKit... ?
Alternative Solution: Add CCLayerColor to base layer.
-(void) onEnter
{
[super onEnter];
ccColor4B color = {255,255,0,255};
CCLayerColor *colorLayer = [CCLayerColor layerWithColor:color];
[self addChild:colorLayer z:LAST_LAYER_PLUS_1];
}
My applications crashes when I try to add a layer in it with CCSprite.
Here is some code I use:
CCLayer *layerPause = [CCLayer node];
CCSprite *spriteBackgroundPause = [[CCSprite alloc] initWithFile:#"BackgroundMenu.jpg"];
[layerPause addChild:spriteBackgroundPause];
[self addChild:layerPause z:27];
Here is picture also:
You have to retain the layerPause variable because it seems an autoreleased object, try in this way :
CCLayer *layerPause = [[CCLayer node] retain];
CCSprite *spriteBackgroundPause = [[CCSprite alloc] initWithFile:#"BackgroundMenu.jpg"];
[layerPause addChild:spriteBackgroundPause];
[self addChild:layerPause z:27];
Why not do it simple .. ? Like this:
CCLayer * layer = [CCLayer alloc]init];
[self addchild: layer];
CCSPrite * sprite = [CCSPrite spriteWithFile:#"ImageName.png"];
[layer addChild:sprite];
I am using 3 CCLayers in one Scene and I want simultaneous game play on all three layers, while user will play the game by switching between these layers. I can switch between these layers easily but my scheduled methods are not being called at all
Thats how I am doing it in the init() method of my scene and the line [self schedule:#selector(gameLogic:) interval:1.0]; is not working for me
Please help me where I am getting it wrong.
layer1 = [CCLayer node];
layer2 = [CCLayer node];
layer3 = [CCLayer node];
// add layer as a child to scene
[self addChild:layer1];
[self addChild:layer2];
[layer2 setVisible:NO];
[self addChild:layer3];
[layer3 setVisible:NO];
CCLabelTTF *layer1Label = [CCLabelTTF labelWithString:#"Layer1" fontName:#"Marker Felt" fontSize:64];
CGSize size = [[CCDirector sharedDirector] winSize];
layer1Label.position = ccp( size.width /2 , size.height/2 );
[layer1 addChild: layer1Label];
CCLabelTTF *layer2Label = [CCLabelTTF labelWithString:#"Layer2" fontName:#"Marker Felt" fontSize:64];
layer2Label.position = ccp( size.width /2 , size.height/2 );
[layer2 addChild: layer2Label];
CCLabelTTF *layer3Label = [CCLabelTTF labelWithString:#"Layer3" fontName:#"Marker Felt" fontSize:64];
layer3Label.position = ccp( size.width /2 , size.height/2 );
[layer3 addChild: layer3Label];
[self schedule:#selector(gameLogic:) interval:1.0];
}
return self;
}
Ohh dear I got it set myself. The problem was nowhere in init(). [super onEnter] was missing in -(void)onEnter method. Now all my scheduled methods are doing fine.
i am adding overlays to a cocos2d layer in preparation for a screenshot...
CGSize winSize = [[CCDirector sharedDirector] winSize];
CCScene* currentScene = [[CCDirector sharedDirector] runningScene];
GameLayer* topLayer = (GameLayer *)[currentScene.children objectAtIndex:0];
CCSprite *middleBackground = [CCSprite spriteWithFile:#"mid_bg.png"];
middleBackground.position = ccp(winSize.width * 0.5,winSize.height * 0.55);
[topLayer addChild:middleBackground z:3 tag:111];
CCSprite *bottomBackground = [CCSprite spriteWithFile:#"bot_bg.png"];
bottomBackground.position = ccp(winSize.width * 0.5,winSize.height * 0.1);
[topLayer addChild:bottomBackground z:3 tag:112];
CCSprite *topBackground = [CCSprite spriteWithFile:#"top_bg.png"];
topBackground.position = ccp(winSize.width * 0.5,winSize.height * 0.94);
[topLayer addChild:topBackground z:3 tag:113];
[[UIApplication sharedApplication] setStatusBarHidden:YES];
CCSprite *topBackground2 = [CCSprite spriteWithFile:#"statusCover2.png"];
topBackground2.position = ccp(winSize.width * 0.5,winSize.height * 0.992);
[topLayer addChild:topBackground2 z:3 tag:114];
[[topLayer popoverController] dismissPopoverAnimated:YES];
then
[UIImage imageWithCGImage:UIGetScreenImage()];
However the later is not taking the overlays into account. It is taking a screenshot of the layer before the overlays are added.
Is there anyway I can tell the cocos2d scene/layer to update the frame NOW?
Because cocos2d is asynchronous you can't tell it to do something like that. However, you can schedule a callback to happen in two seconds and have that callback do the screen capture.
[self schedule: #selector(screenshot:) interval:2.0];
then define the selector like this:
-(void) screenshot:(id)sender {
[UIImage imageWithCGImage:UIGetScreenImage()];
[self unschedule:#selector(screenshot:)];
}
don't forgot to unschedule it.
