Conventions

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

Code words in text folder names, filenames, file extensions, pathnames, dummy URLs, and user input are shown as follows: "In order to add accelerometer support to our game, we are first going to add the following method declaration to our HelloWorldScene.h header file."

A block of code is set as follows:

void HelloWorld::movePlayerByTouch(Touch* touch, Event* event)
{
  Vec2 touchLocation = touch->getLocation();
  if(_sprPlayer->getBoundingBox().containsPoint(touchLocation)){
    movePlayerIfPossible(touchLocation.x);
  }
}

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

   Size screenSize = glview->getFrameSize();
   Size designSize(768, 1280);
   std::vector<std::string> searchPaths;   
   searchPaths.push_back("sounds");

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

cocos new MyGame -p com.your_company.mygame -l cpp -d NEW_PROJECTS_DIR

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: "Clicking on the Next button moves you to the next screen."
