This is a follow-up to the GravityGuy with Bounce demo. The logic error that let GravityGuy sink thru the floor has been corrected, and now he can jump. There is some extra "unconnected" code included in the project. If you download the project and connect the extra code, GravityGuy will gain a new ability.
Remember that there are lots of ways to accomplish things in Scratch, there is nothing magical about the way I did things or the variable names. This program is built a bit differently from the previous ones, using more "Broadcasts".
As with the other projects, lots of comments are included that should make it clear how the program works. Feel free to download and use as desired, either to study or to remix.
