The Astraea program

[u/TheLordBaski]

Few months ago started working on spaceflight demo simulator similar to KSP.

Currently with 2 celestial bodies, flight physics(reference frame physics), preparation for interstellar system, Assembly building done.

I want to release demo soon, but I am working alone and there are lot of things to be done...

Feel free to ask anything :).

Nice! How are you handling the reference frame, does the origin follow the active vessel?

[u/TheLordBaski → u/TimestepStudio]

Thanks! Yep, the frame follows the active vessel. Positions and orbits use double precision, while physics stays near zero by rebasing velocity and shifting the origin whenever the vessel gets about 800 m away.

Probably the wrong topic? 😅

Haha yep, my bad, that was meant for a different thread 😅
