Scaling a CocosNode from the center (0.8.2)

Hi all, I'm using 0.8.2.

I've created a CocosNode:

_gameBoard = [CocosNode node];

Then added that node to the scene:

[self addChild:_gameBoard];

After this, I've added a number of child sprites to _gameBoard.

My main issue is that when I use _gameBoard.scale = 0.5f; the scale effect occurs from bottom-left of the iphone screen. I need to scale from the middle of the _gameBoard.

I've tried:

[_gameBoard setAnchorPoint:ccp(0.5f, 0.5f)];

With no success.

Any ideas guys?

Many thanks!

I thought I might have answered my own question but alas, setting [_gameBoard setAnchorPoint:ccp(0.5f, 0.5f)]; AFTER I have added children to the _gameBoard still makes no difference :o(

OK, I've definitely answered it myself this time... for anyone else having problems:

You need to define the width and height of the CocosNode even if you add child objects to it before the scale will work properly with setAnchorPoint.

To do this, use the setContentSize method.

Thanks.

Yes, a CocosNode by default has a contentSize of (0,0).
