title: How would one use Cocos2d to create a game like this
body: <p><a href="http://itunes.apple.com/us/app/angry-birds/id343200656?mt=8&amp;ign-mpt=uo%3D6" rel="nofollow noreferrer">http://itunes.apple.com/us/app/angry-birds/id343200656?mt=8&amp;ign-mpt=uo%3D6</a></p>
  
  <p>So I am getting started with this all game dev thing on iphone and I decided that I will start playing with Cocos2d as my starting engine. </p>
  
  <p>Now just so i have a goal in mind, I picked angry birds as my initial target of what sort of game play would I like to learn to build. This is <em>not</em> going to be a market release game. This is <strong>totally</strong> going to be learning purposes only.</p>
  
  <p>So to start off my question is:</p>
  
  <ul>
  <li>Would something like this be achievable using Cocos2d?</li>
  <li>How would I go about building the physics for this?</li>
  <li>How can one do a screen scroll like the way they do in cocos2d? (any example code would be great)</li>
  </ul>
  
  <p>This is just to start off. If you have any particular questions please do add to this question.</p>

  <p>Few more things that I am wondering about:</p>
  
  <ul>
  <li>animated sprites. How does one create that? Is that a Cocos2d feature or i can use UIImageView?</li>
  <li>drag and drop support. How do they detect that I am dragging the bird? </li>
  <li>More of a graphics question: how do they animate the "band stretch" effect?</li>
  </ul>
  
  <p>cheers</p>

  <p><strong>Progress</strong></p>
  
  <p>So i have been able to setup a world in Cocos2d along with box2d and now i have a few blocks that collide and simulate physics. Now I am having issues that I think can be resolved by further hints/help/tutorials.</p>
  
  <ol>
  <li><p>How do I make a sprite move in an arc? Like when u throw the bird it moves along a curve. How can I calculate that? where does that logic go? (built-in or needs to be coded?)</p></li>
  <li><p>How do I create a world (maps) where certain blocks are static and certain are breakable? Should I look into SVG support in cocos2d? </p></li>
  <li><p>How do I simulate collision like they do in angrybirds? </p></li>
  </ol>
  
  <p>cheers.</p>
