  <p>but i am getting this warning again and again and no sprite shows up on the screen
  original Width/Height not found on the CCSpriteFrame. AnchorPoint won't work as expected. Regenerate the .plist
  i tried resizing and untrimming but the erro persists...i cannot figure out the problem?? heres my code</p>
  
  <pre><code>[[CCSpriteFrameCache sharedSpriteFrameCache] addSpriteFramesWithFile:@"hentry.plist"];        
  
      CCSpriteBatchNode *spriteSheet = [CCSpriteBatchNode batchNodeWithFile:@"hentry.png"];
      [self addChild:spriteSheet];
  
      // Load up the frames of our animation
      NSMutableArray *walkAnimFrames = [NSMutableArray array];
      for(int i = 2; i &lt;= 3; ++i) {
          [walkAnimFrames addObject:[[CCSpriteFrameCache sharedSpriteFrameCache] spriteFrameByName:[NSString stringWithFormat:@"%d.png", i]]];
      }
      CCAnimation *walkAnim = [CCAnimation animationWithFrames:walkAnimFrames delay:0.1f];
  
      // Create a sprite
      CGSize winSize = [CCDirector sharedDirector].winSize;
      self.bear = [CCSprite spriteWithSpriteFrameName:@"2.png"];
      _bear.position = ccp(winSize.width/2, winSize.height/2);
      self.walkAction = [CCRepeatForever actionWithAction:[CCAnimate actionWithAnimation:walkAnim restoreOriginalFrame:NO]];
      [_bear runAction:_walkAction];
      [spriteSheet addChild:_bear];
