Realistic orbital physics?

Is it possible to make working orbit physics like in orbiter or kerbal space program?

Yes, there are some functions in GD that allows to put an object at a specific distance of another object or position in a specific angle.

So, the tools to visually implement orbital realistic physics are there but you have to do the math:

I’ll see if I have Gravicannon laying around anymore.

//edit: It’s here: dl.dropboxusercontent.com/u/210143/gcannon.rar but you’ll need to fix it. Somehow it got broken (probably because it was made with GD 2.xx), culprit seems to be function events.
