Am I correct that grid based effects can only be apply to the whole scene?
Is there a way to apply a grid based effect to a child node or some sprite which only occupy a small area of the screen?
I’ve been read this thread
// inside application:didFinishLaunchingWithOptions:
EAGLView *glView = [EAGLView viewWithFrame:[window bounds] pixelFormat:kEAGLColorFormatRGBA8 depthFormat:GL_DEPTH_COMPONENT16_OES];
How can i implement this code in Cocos2d-x?
