   AtlasSpriteManager question for newbie to cocos2d iPhone, we are adding an AtlasSpriteManager, and want to know once we have added a sprite using the following code:

   [mgr addChild:sprite z:1];

   how do we change the frame to a different frame using our own animation code as we cant use cocos2d for this.

   The reason we ask is we have 16 frames of animation on a singe .png file which we will load with AtlasSpriteManager, but we want our pmgr addChild:sprite z:1]; to be able to show any of these 16 frames as we need

   Thanks for any help, much appreciated

   I prefer to use [sprite setDisplayFrame:1]; etc. but this is not working for atlassprites, any ideas please?

   we use [animation addFrameWithRect: CGRectMake etc] to add each frame so can we not use [sprite setDisplayFrame:1]; etc. to show the frames we added?

   As right now it always says invalid frame

   There's a related discussion here : http://www.cocos2d-iphone.org/forum/topic/1648

   The setDisplayFrame method of the AtlasSprite class expects an AtlasSpriteFrame as a parameter. You may want to use this method instead : setDisplayFrame:index:

   Because setDisplayFrame takes an AtlasSpriteFrame object as a parameter and you're passing an int ?

    Ah :( well yes I have tried with AtlasSpriteFrame but not the best way of doing, can we not set frame numbers when we load images and also allow setDisplayFrame to work as makes sense

    But thanks

    Passing the wrong data type to the function simply because you wish it worked a differentt way doesn't magically add the feature you want.

    You could always make an array of AtlasSpriteFrames and then reference an index number of your array.

    I understand that but was wondering if it was planned to add such feature to cocos2d to save having arrays in our applications for this, as it makes sense to include the facility to set the frame by index
