I see that have now a method on proj.mac that do it.
But when i go to full screen 1024x768, the sprites was stretched.
How i can solve it?
static cocos2d::Size designResolutionSize = cocos2d::Size(1024, 768);
eglView->setDesignResolutionSize(designResolutionSize.width, designResolutionSize.height, ResolutionPolicy::SHOW_ALL);
On 1024x768 windowed mode, it is OK, but on fullscreen it stretched the image.
Thanks for any help.
