Conventions

You will also 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: "For background music volume, you must use setBackgroundMusicVolume."

A block of code is set as follows:

CCScene* GameLayer::scene()
{
   // 'scene' is an autorelease object
   CCScene *scene = CCScene::create();
    
   GameLayer *layer = GameLayer::create();

   scene->addChild(layer);

   return scene;
}

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

//add score display
_player1ScoreLabel = CCLabelTTF::create("0", "Arial", 60);
_player1ScoreLabel->setRotation(90);
this->addChild(_player1ScoreLabel);

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

sudo ./install-templates-xcode.sh -u

New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "In the dialog box select cocos2d-x under the iOS menu and choose the cocos2dx template."
