title: Creating animated sprites for cocos2d from a single image file without a .plist file
body: <p>I am starting to learn cocos2d and I have the following issue:</p>
  
  <p>I cannot seem to find a way to create sprite frames from a single png sprite file and animate them. I have found a million tutorials about using separate image files or a plist file with the png but I can't find how to do it WITHOUT one (with a regular loop that selects rectangular areas. Any help?</p>
