You need to enclose your code in an -(id)init method, like this:
#implementation Background
- (id)init
{
if (self = [super init]) {
// Load the sprites for each parallax layer, from background to foreground.
CCSprite* para1 = [CCSprite spriteWithFile:#"color.png"];
// ... the rest of your code ... //
}
return self;
}

I'm wondering as to where to put CGRectInteresectRect part of the code. As I've currently tried placing within the SpaceJunk alloc init part and it doesn't remove the child when the ship collides with the junk.
int setInterval = (arc4random() % 3);
[self schedule:#selector(gameLgoic:) interval:setInterval];
Make setInterval value to float and give small value for schedular.
Also not do [spaceThings runAction inside loop. if required then do some condition check and run only if required.
Then your CGRectIntersectsRect will fire when intersect each other.
Happy Coding.

Your AnimatedBG method should be defined as:

You should also make sure you have a definition for your scheduled tick: method:
-(void) tick:(ccTime)dt {
}
As the title, I have mentioned the code below
CCSprite *sprite = (CCSprite *)node;
CCTexture2D *texture2d = [sprite texture];
How can I get a UIImage *p from sprite?
In your case just add next methood into your class:
- (UIImage *) imageFromSprite :(CCSprite *)sprite
{
int tx = sprite.contentSize.width;
int ty = sprite.contentSize.height;
CCRenderTexture *renderer = [CCRenderTexture renderTextureWithWidth:tx height:ty];
sprite.anchorPoint = CGPointZero;
[renderer begin];
[sprite visit];
[renderer end];
return [renderer getUIImage];
}
how to use:
CCSprite *sprite = (CCSprite *)node;
UIImage *p = [self imageFromSprite:sprite]
uhh...
I think this is a better to way. Add this as a category on CCNode.
-(UIImage*)image {
CCRenderTexture* renderer = [CCRenderTexture renderTextureWithWidth:self.contentSize.width height:self.contentSize.height];
const CGPoint ANCHORBEFORE = self.anchorPoint;
self.anchorPoint = CGPointZero;
[renderer begin];
[self visit];
[renderer end];
self.anchorPoint = ANCHORBEFORE;
return [renderer getUIImage];
}
If you are using cocos2d 2.x, render sprite into CCRenderTexture and call getUIImage method of that render texture.
By looking at the source code of both CCSprite and CCTexture2D you can see that the image is used only for creating the texture data and the image object is not kept but temporarily used.
CCTexture2D source :
http://code.google.com/p/cocos2d-iphone/source/browse/trunk/cocos2d/CCTexture2D.m?r=1882
CCSprite source :
http://code.google.com/p/cocos2d-iphone/source/browse/trunk/cocos2d/CCSprite.m?r=1747
Look in the init methods that use CGImageRef
I am coding a modal layer in cocos2d and I would like to use the OpenGL glScissor API call to crop the inside of a CCScrollLayer that I am using,
Basically,
Present some kind of Modal sprite
Put CCScrollLayer with assets on the modal sprite
I want to crop the CCScrollLayer so that it does not overflow the sprite.
Seems pretty simple.
The problem I'm having is that the visit function never seems to be get hit and thus glScissor never gets implemented.
I'm not sure what I'm doing wrong.
The way I do modals is I use blocks to handle a Yes and No condition/state.

I think its because I only ever use MapModalLayer's private methods only.
But I am not sure.
Is there a way to allow me to use the glScissor in a modal like explained above?
I've tried moving the glScissor code to the display of the modal, but it never seems to do anything.
To confirm it is working, I moved the glScissor code to the parent and it seems to work fine.
Thus, how do I make the modal layer use/work with glScissor?
I have since resolved this problem.
I used the Viewport from http://pastebin.com/tWsEbxvJ
The way I did it was:
CoverLayer *coverLayer = [CoverLayer new];
[layer addChild:coverLayer z:INT_MAX]; // put to the very top to block application touches
[coverLayer runAction:[CCFadeTo actionWithDuration:kAnimationTime opacity:80]]; // smooth fade-in to dim with semi-transparency
// ------------------------------
CGSize winSize = [[CCDirector sharedDirector] winSize];
CCSprite *dialog = [CCSprite spriteWithSpriteFrameName:#"modal.png"];
[dialog setPosition:CGPointMake(winSize.width/2,winSize.height/2)];
[dialog setTag:kDialogTag];
.. // Build your pagesArray here for ScrollLayer...
// Now create the scroller and pass-in the pages (set widthOffset to 0 for fullscreen pages)
CCScrollLayer *scroller = [[CCScrollLayer alloc] initWithLayers:pagesArray widthOffset: 350];
[scroller setShowPagesIndicator:NO];
// finally add the scroller to your scene
//[dialog addChild:scroller];
Viewport *cn = [[Viewport alloc] initWithRect:CGRectMake(3, 0, dialog.contentSize.width-12, dialog.contentSize.height-5)];
[cn addChild:scroller];
[scroller release];
[coverLayer addChild:dialog z:1];
This allows me to put a modal on a layer, put a CCScrollLayer and make sure that the contents do not spill over the internals of the modal sprite I have made (this is why the width configuration looks a bit odd).
Thanks.
Hi stackoverflow community!
How do you detect a children sprite collision with a parent sprite in cocos2d?
Currently I have my codes like this:
CGSize screenSize = [[CCDirector sharedDirector]winSize];
parentJumper = [CCSprite spriteWithFile:#"inviBtn.png"];
jumper = [CCSprite spriteWithFile:#"jumperRight.png"];
plat = [[Platform alloc]init];
plat = [Platform spriteWithFile:#"platformBlack.png"];
plat.position = ccp(160,100);
[[UIAccelerometer sharedAccelerometer] setUpdateInterval:(1.0/60)];
jumper.anchorPoint = ccp(0.5, 0);
jumper.position = ccp(0, 20);
parentJumper.position = ccp(screenSize.width/2, 0);
[self addChild:plat];
[self addChild:parentJumper];
[parentJumper addChild:jumper];
Now how do I detect the collision between "jumper" & "plat"?
Thanks for your help!
Usually you can check collision like this:
if(CGRectIntersectsRect([jumper boundingBox], [plat boundingBox])) {
//Handle collision<br>
}
