For an explanation on how you can use these scripts in other projects, see inside. You can move the "sun" (or whatever that is) around in the player.
After being inspired by Zro716's project, Galaxy (http://beta.scratch.mit.edu/projects/10035476/), and fiddling around with the code, I decided to try my hand at building an engine from scratch (puns!). Hopefully people will use this to make some amazing projects, and tell me if you do 'cause I want to see them! Ideas for ways to use this: Space flight simulators Particle simulators Solar system generators Atom/electron simulations etc.
