LSD

Short for Laser Sea Destruction, this is a library by Adam Bielinski for the programming environment processing. Last update, 04/27/2011.

This library has some features that are a little too far away from Processing's focus group of designers. It follows the idea of making along the lines of creating simple games quickly by finding an example game and modifying everything to fit your needs

Some features are:

Time-based animation

Frame-map loading

Image caching

Tilemaps

Reasonable 2D fixed-timestep physics (This still needs work...)

A simple display list so that sprites are shown in the correct order

An organization framework for simple games

A simple to use keyboard input system

It's still in development and I would only reccomend it for simple games. But soon more!
