Universe Sandbox 2D

This is a universe simulation inspired by sandbox universe (I don’t actually own that game). It’s main goals is to simulate movement of planets and other astronomical bodys as realistically as possible.

In my version you can create and manipulate all planets simply by clicking on it or dragging it around. Also feel free to simulate everything in real-time (spoiler: it’s quite boring) or speed things up up to 10E9 times. Same goes for visuals: since the universe is pretty big (I think) and planets are rather small you can scale the planets visual appearance.

One of the key features of this project is actually the UI. All hand-coded, the menus allow for (for Greenfoot standards) many advanced runtime controls, like sliders, switches, selections or complete menus. All you see here can easily be reused.


Future objectives:
- Add option to manipulate speed of objects
- Include special and general relativity in physics (time and distance dilation, spacetime)
- Improve collision physics
- Improve objects graphics
