Demos & examples. Luca Masini's Weblog. A Comet implementation for Google Web Toolkit These days there are two hot technologies in Web community: With the first we can write JavaScript application in Java, with a rock solid support for an event system and a rendering engine that make live our web interfaces, the last is a new word for an old technology, where we use a persistent socket created from the client to push data from the server, all done in a "pure" web application.
So I decided to put the two together and let GWT receive events from a mainstream server, and the result is what I'm going to describe. The StreamingServiceFactory class This is the only class that the user (I mean the GWT client) has to cope with. It has only three public methods, one to get a pointer to the singleton instance (getInstance), another to subscribe to an event queue (subScribeToEvent), and the last one, of course, to send events to a queue (sendMessage). Let see how to use it: ssf.subScribeToEvent("chat", new ChatCallback("chat")); MultiPlayer AJAX game with GWT ? - Google Web Toolkit. GWT Simcity like game - Google Web Toolkit. How do I make a browser game. CSCI N451 Game Programming. Section Information Greeting I'm excited to be working with you on this fascinating topic. Game development is a hot topic right now, but far few people understand what makes game development a unique form of programming.
In this class we'll take a high-level look at the strategies, algorithms, and techniques of game development. Flash handles low-end processes automatically, allowing us to quickly talk about higher-level game design concepts.
