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: "Play around with some of the other actions on your obj_square to make it do more rather than be displayed and print text."

A block of code is set as follows:

if (keyboard_check_pressed(vk_up) && !binding) {
       if (choice <= 0) choice = 2;
       else --choice;
}

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: "At the bottom of the resource tree are the Game Information and Global Game Settings options."
