   Added The AtlasSpriteTest header and implementation files to a sample project to test them out (wrong way?). But I get compile errors because things like vectexZ and anchorPoint and a bunch of other stuff are not in the AtlasSprite and AtlasSpriteManager. I checked both 0.7.3 and 0.8beta and, sure enough, they aren't. What am I doing wrong?

   I think anchorPoint is a property of cocosNodes, that is why you can't find it in neither of those classes

   I can't seem to find it there either, in any case, I didn't modify anything, so whether I found it or not, I figured it should compile.

   Seems like the issue is that the tests use the latest revision of the framework. Is there an easy way to keep my framework up-to-date or is there somewhere I can get the AtlasSpriteTest version that would work for one of the release version frameworks?

   well anchorPoint is from 0.8 so you will not find it in 0.73.
   What errors are you getting exactly?

   sorry for the late response,
   for example for this;
   for(int i=5;i<11;i++) {
   AtlasSprite *sprite = [AtlasSprite spriteWithRect:CGRectMake(85*1, 121*0, 85, 121) spriteManager: mgr];
   sprite.position = ccp( 50 + i*40, s.height/2);
   sprite.vertexZ = 10 + (10-i)*40;
   [mgr addChild:sprite z:0];
   }

   I get "request for member vectorZ in something not a structure or union
   same for error for other members as well

   try this instead:

   [sprite setVertexZ:100];

   This can be found here:

   before I try anything, I just want to know why it's like that in the tests?
   I got it from here;

   well i tried with both ways and it works ok for me, maybe you are missing something... are you sure you are using the latest version?

    Unfortunately now I'm not sure how to get it up and running. I added AtlasDemo layer to a Scene but it just crashes when I run it

    Edit: nevermind, I see it has like its own App Delagate

    Okay, so now I need some advice on real world usage. If I'm like making bullets firing from a fighter plane, I'm guessing its a good idea to use an AtlasSpriteManager. The issue is that there's going to be a lot of being fired at a given level. So What's the best way to handle this? Should I just let the Manager accumulate all the sprites without clearing?

    I think yes, you should have an NSArray with x AtlasSprites, and fire them accordingly.

    In my game i allocate on init 30 AtlasSprites and then i make them appear when the time is right.

    Or you could add them to your scene on the fly, but it will consume more CPU time if they are a lot.

    so you think I should just create like a fixed amount per vehicle and recycle them?
