Basic Jumping Demo I did in about 30 minutes. Helpful for n00bs. Thanks to X_MEN for some of the source I got from a topic someone posted.

You can use this to learn basic techniques of gravity and whatnot. It's probably good for the usual topic's about gravity in 2d and how to make them jump. I got alittle help from a topic about it posted by db programmer 12, and X_MEN. Well enjoy.

Peace Out -
