   I'm having some trouble trying to make a sprite appear to be standing on a layer of a TMX map.
   Once the z order I give the sprite is higher then the bottom layer of my .tmx map, it always appears on top of my all my layers.
   I want it to appear to be standing on layer 1 but under the higher layers.
   Here is my code:

   CCTMXTiledMap *map = [CCTMXTiledMap tiledMapWithTMXFile:@"testmap4.tmx"];
   [self addChild:map];

   //
   [map reorderChild:[map layerNamed:@"Layer 0"] z:1];
   [map reorderChild:[map layerNamed:@"Layer 1"] z:2];
   //Adding a player sprite
   CCSprite *player = [CCSprite spriteWithFile:@"h1.png" rect:CGRectMake(0, 0, 24, 48)];
   player.position = ccp(240, 160);
   [self addChild:player z:3];
   [map reorderChild:[map layerNamed:@"Layer 2"] z:4];
   [map reorderChild:[map layerNamed:@"Layer 3"] z:5];
   [map reorderChild:[map layerNamed:@"Layer 4"] z:6];

   The sprite looks like it's on z:7 or higher all the time.

   Have you tried adding it as a child of the map instead of a child of the map container?

   How would I go about doing that?
   [map addChild:player]; ?

   @Neo-Dragon: See the TMX examples from SVN trunk. It includes 2 examples that show how to do it.

   Which one? I was thinking it might have been the read/write test in the TileMapTest.m, but can't see anything to do with placing a sprite to appear to be on a layer <as in map layer) z ordering.
   I can mess around with the z ordering of the layers of the map. It's just the sprite won't layer in lol.
   Having another look could it be part of the TMXOrthoTest2?
   I wish there were some noob friendly comments in the examples ha.

   But yeah, still stuck.
   Any help?

   Try what you posted before : [map addChild:player];

   You can see an example inside TileMapTest.m in the current trunk source:

   http://code.google.com/p/cocos2d-iphone/source/browse/trunk/tests/TileMapTest.m

   Check line 854 or 920 for a couple examples ( TMXIsoZorder and TMXOrthoZorder respectively ).

   Hmm. Got it working using:
   //Adding a player sprite
   CCSprite *player = [CCSprite spriteWithFile:@"h1.png" rect:CGRectMake(0, 0, 24, 48)];
   player.position = ccp(240, 160);
   [map addChild:player z:3];
   [player retain];

   The thing I don't understand is I had to place the code the end of the rest of my test map code.
   For testing, I have a few extra things like setting the opacity of a layer or editing some tiles using GID. If I added the [map addChild:player]; it would cause the game to crash (force close).
   Why is that?
