I discover the problem.
When I get the width size of the CCSprite bloco, I get the size of the entire spritesheet, an not only the internal sprite that I want.
I use the following code:
bloco->setPosition(CCPointMake(bloco->getTexture()~~>getContentSize.width/2 + ,
bloco~~>getTexture()->getContentSize().height/2 + (iposY * HEIGHT_DISTANCE)+HEIGHT_BASE));
The upper case variables are constants that I have in my game.
It’s possible to get the width and height for an internal sprite in the spritesheet?
