Flash Multiplayer Virtual Worlds

Overview of this book

Flash virtual worlds are some of the most exciting—and profitable—online business being built today. Using Flash, developers can build interactive environments where users can interact with the virtual world and one another, compete, and have fun. Creating a playful environment on an electronic network presents unique challenges as you combine a fun, upbeat frontend with some serious and complex server logic. This handy book assists you in building amazing virtual worlds in no time by implementing ActionScripts in a Flash IDE. With this book in hand, you will build virtual worlds that have avatars walking around and interacting with non playing characters, completing challenging quests, and allowing users to link with real-world friends. The fun begins with first exploring existing virtual world games such as Club Penguin, Mole, Dofus, and World of Warcraft. We will then design our virtual environment. Then we will create avatars and move the avatars in the virtual world. We will add some triggers to add amusement and life to the virtual world. We will allow the avatars to interact with other players and create a buddy list for each user. Then we will integrate buildings and other environment to the virtual world. We will also let the players interact with non-player characters to complete some tasks. Finally, we move on to add interesting quests to the virtual world, which need to be accomplished by the player to gear up to the next level of the game. This example-rich, hands-on guide sequentially develops a multiplayer virtual world—the platform, the environment, quests, avatars, non-playing characters, and interaction between them.

Saving the position for next time


In a virtual world that has a big map, we need to save the current position of the avatar so that we can resume the position next time when we log in again. We can access the database by using server-side extension.

Creating an avatar database table

There are several ways to perform the MySQL tasks. One easy way is to use the PhpMyAdmin, which is a web-based MySQL admin panel provided by the web server bundles.

Windows users can launch the PhpMyAdmin from the taskbar Wamp2 | phpMyAdmin.

For Mac OSX:

  1. 1. Launch MAMP.

  2. 2. Go to http://localhost/MAMP in the web browser.

  3. 3. Click on the PhpMyAdmin link.

Linux users can go to http://localhost/path_to_phpMyAdmin in the web browser.

It is optional to create a database before creating our first table. This database will hold all the tables of our virtual world. We create a database name flash_virtual_world. In the newly created database, we create a new table named avatar with seven fields in PhpMyAdmin.

We are going to...
