title: Parallax Scrolling for the Endless Game background using cocos2D
body: <p>I am newbie programmer in cocos2D.... I wanted to create the Endless Background using the Parallax Scrolling.. I am trying to learn the Parallax but it doesn't update with the time and sprites doesn't keep on rotating from top to bottom! The snippet i tried is as below</p>
  
  <pre><code>-(id) init 
  {
      if((self = [super init])) 
      {        
          CGSize wSize = [CCDirector sharedDirector].winSize;
          self.isTouchEnabled = YES;
          CGPoint topOffset = CGPointMake(wSize.width, 0); 
          CGPoint midOffset = CGPointMake(wSize.width/2,0);
          CGPoint downOffset = CGPointZero;        
          CCSprite *para1 = [CCSprite spriteWithFile:@"Default.png"];
          CCSprite *para2 = [CCSprite spriteWithFile:@"Icon.png"];
          CCSprite *para3 = [CCSprite spriteWithFile:@"Default.png"];
          CCSprite *para4 = [CCSprite spriteWithFile:@"Icon.png"];
  
          paraNode = [CCParallaxNode node];
          [paraNode addChild:para1 z:1 parallaxRatio:CGPointMake(0.5f, 0)
          positionOffset:topOffset];
          [paraNode addChild:para2 z:2 parallaxRatio:CGPointMake(1, 0) positionOffset:topOffset];
          [paraNode addChild:para3 z:4 parallaxRatio:CGPointMake(2, 0) positionOffset:midOffset];
          [paraNode addChild:para4 z:3 parallaxRatio:CGPointMake(3, 0) positionOffset:downOffset];
          [self addChild:paraNode z:0 ];
          [self scheduleUpdate];
       }
       return self;
  }
  
  -(void) update : (ccTime) dt
  {   
  //Need to move the Parallax Node with the repetition of the background
  }
  </code></pre>
  
  <p>This is the Implementation file... I am stuck here for moving the contiunous moving of the background in the Horizontal or Portrait mode.</p>
  
  <p>Thanks for the Help in Advance</p>
