Excerpt of article text...
Introduction
This is the third (and final) article about designing and building a networked version of TanGram, a game in which players drag around polygonal shapes and arrange them to make pictures. As you may recall from the two previous articles, I have been adding networked play to the original TanGram application that we built over six earlier articles in this column. In this article I will wrap up TanGram once and for all by implementing the ability to automatically gather up and display a list of all the players in a TanGram network group. This is functionality we would get for free if we used the AutoDiscovery class, but I decided to use EasyUDPSocket and not the AutoDiscovery class to implement TanGram's networking. So if we want a group list, we will have to write it ourselves.
Another feature I intend to implement in this article is the ability to whisper to individual players. Whispers are messages to a single player that are not seen by the entire group. It turns out to be quite simple to add such a feature, as we will see.
