   this is my sprite init code:
   

   CGSize s = [[CCDirector sharedDirector] winSize];
   mgr = [[CCSpriteSheet spriteSheetWithFile:@"lvl1_anim1024.png" capacity:50] retain];
   pet_shadow = [mgr createSpriteWithRect: CGRectMake(0,755, 97, 15)];
   pet_sprite = [mgr createSpriteWithRect: CGRectMake(0,0, 109, 82)];
   [pet_sprite addChild:pet_shadow z: 0 tag: 0];
   pet_shadow.anchorPoint = ccp(0, 0.3);
   [pet_sprite setPosition: ccp(s.width / 2, s.height / 2 - 80)];
   pet_sprite.scale = 1.0f;
   [mgr addChild: pet_sprite z:0 tag:1];
   [self addChild:mgr];

   I've upload a vid show the problems:
   -the shadow doesnt move with the body.
   -And for some reason theres a second shadow at bottom left of the screen.
   - is there anyway i can render child node first? right now shadow is already render after the body because its the child node.

   THanks.

   regarding the shadow below the pet, try with a negative z. eg:
   

   [pet_sprite addChild:pet_shadow z:-1 tag: 0];

   regarding the shadow not moving... emm.... very strange... it should work... it is working OK on the tests. Please, see the tests and compare your sources with with them (tests/SpriteTest.m) to see if you are doing something different.

   thx Riq, set z =-1 put the shadow underneath the pet, n also get rid of the duplicated shadow.

   I'm gonna do a line to line compare to SpriteTest see if i can hunt down the problem source.

   Hi again, I have found out what the problem is.

   This is how my walk action is composed:
   

   CCAnimate* walk_animate = [CCAnimate actionWithAnimation:walk_animation restoreOriginalFrame:YES];
   CCRepeat* repeat = [CCRepeat actionWithAction:walk_animate times:stepcount];
   CCMoveTo* move = [CCMoveTo actionWithDuration:(stepcount * 0.5) position: pos];
   CCSpawn* walk = [CCSpawn actions:repeat, move, nil];
   walk_action = [[CCSequence actions:scale, walk, nil] retain];

   And the reason is that since shadow has only 1 frame it can't not perform the animate action above, so it just skip thro the entire walk action.

   Is there any way I can work around this?

   ok for anyone who has the same problem. Ive fixed this bug buy change line 4 to this
   CCSpawn* walk = [CCSpawn move, repeat, nil];
   that way the shadow will still perform move action then skip repeat.

   THx Riq
