Layer, move, scale and centered AnchorPoint

Hello,

I've got a layer that is moved during my game with the CCMoveTo action.
I can't scale this layer to an anchor point centered of the screen (0.5, 0.5 in world space), regarding is current position.

Does the anchor point is defined in the node space, so do I have to convert the percent couple from world to node space ? I've tried with self.relativeAnchorPoint = YES or NO and self.anchorPoint = ccp(0.5,0.5). Maybe, there is a new method to set the AnchorPoint in pixel coordinate (the anchorPointInPixel that's is now read only in the 0.9 version) ?

Thanks a lot,

C.

Ok, so indeed the anchorPoint is in the node space. So I used layer.contentSize.width/height to calculate the percent couple in the node space.

But the problem is when I change the anchorPoint, my layer is moved on the screen. I imagine this is because he attach to his parent (the scene) with this anchorPoint. I could change his position in the opposite direction at the same time, but as expected, it works but horribly flashes the screen.

What could solve it is to used something like "CCSetAnchorTo" instead of my CCMoveTo action, to both change the position on the world screen and the anchor point in the node space. But nothing like that in the API (look at the CCIntervalAction Class Reference > inherited by).

Any idea :) ?
