J2me Games General Graphics Effects Library Implementation And Optimization

By the rapid development of information technology, mobile phones are widely used and mobile games have become important entertainment to the modern people especially the youth. The mobile games has reached a very large market around the world and the amount of the game developers and companies grown up. Many good games have been published. But behind the large amount of games, the develop is facing great problems by the limit of the handset's performance and the J2ME platform. The worst part of develop is that the handsets is too slow to perform satisfying effects when drawing too much things. The low speed is destroying consumers'game experience.The graphic effects library is a technique used when developing a mobile game, it is developed recording to certain kind of game and provides nice 2D graphics effects with acceptable painting speed. Developing a graphics effect library is quite necessary when developing a game, especially when developing a Control Game (like car racing,flying,shooting games etc). By this technique we can implement nice effects in game with acceptable speed after optimization. The graphic effects library can help the game developers to improve the quality of mobile game and provide a nice game experience to consumers. This article will focus on this point.This thesis analyzed the shortcoming part of current mobile game developing and the needs in graphic effects, improved the image sprite system provided by J2ME, discussed and optimized current develop techniques and build a graphic effects library based on the improvement. This effects library implements effects on different kinds of games, particle systems and improved image sprite engine. At the end this thesis discussed the optimization design of the library and proves the achievement of this article by test and compare.
