Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “One of the Godot Engine’s Network API core features is the ENetMultiplayerPeer class.”

A block of code is set as follows:

func _process(delta):
    server.poll()
    if server.is_connection_available():
        var peer = server.take_connection()
        var message = JSON.parse_string(peer.get_var())
        if "authenticate_credentials" in message:
            authenticate_player(peer, message)
        elif "get_authentication_token" in message:
            get_authentication_token(peer, message)

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “From there, we first need a server. So, choose one instance and press the ServerButton.”
