Conventions

In this book, you will find a number of text styles that distinguish between different kinds of information. Here are some examples of these styles and an explanation of their meaning.

Code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles are shown as follows: "We will then create the _sprite1 and _sprite2 variables. In spriteWithImageNames, we will pass the filename variable that will hold the string of the filename."

A block of code is set as follows:

#import "CCSprite.h"

@interface ParallaxSprite :CCSprite{

  CGSize _winSize;
  CGPoint _center;
  CCSprite *_sprite1, *_sprite2;
  float _speed;
}


-(id)initWithFilename:(NSString *)filename Speed:(float)speed;
-(void)update:(CCTime)delta;

@end

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

#import "Hero.h"
#import "ParallaxSprite.h"

@interface MainScene :CCNode{

CGSizewinSize;
    Hero* hero;
ParallaxSprite* pSprite;

}

Any command-line input or output is written as follows:

./install.sh -i

New terms and important words are shown in bold. Words that you see on the screen, for example, in menus or dialog boxes, appear in the text like this: "Next, we will give it a class name. We will select CCSprite as Subclass of and Objective–C as Language."

Note

Warnings or important notes appear in a box like this.
