Solar System Simulator Game

Hello,

I have uploaded the code for my Solar System Simulator Game in GitHub as a small open source project.
I hope somebody finds it useful.

Hey Sotos,

Looks really great! Just wondering, did you also upload a .exe? My physics teachers loves this kind of stuff and I would like to show him this. I would need a .exe to run it at school.

Well done.

 

Hello,

there is no .exe but you can compile the project by yourself and build the executable.

 

Okay, no problem. Nice job anyway

 

This is really nice! Thanks for sharing. Beautiful music as well.

I'm trying to learn how to calculate realistic planetary positions based on time, but I'm not very good with maths so I'm looking for inspiration on the internet. This is the best Unity project for realistic orbit calculations I've seen so far, as it uses Kepler orbital mechanics, which seems like the best balance between accuracy and speed.

If I'm not mistaken, you don't seem to render orbital inclination (the angle of the orbital plane, or in other words the position of the planets on the Y-axis). Do you think this would be tricky to add? I was thinking of maybe using built-in Unity rotation for this, but not sure it would work with elliptical orbits.

Thanks again for sharing, and good luck with everything.

 

Hello,

> Do you think this would be tricky to add?

Not at all, it is just a rotation matrix:

RotationMatrix[phi, theta, psi] = Transpose[ RotationMatrix[psi, {0, 0, z}].RotationMatrix[theta, {x, 0, 0}].RotationMatrix[phi, {0, 0, z}]]; in pseudocode

where phi, theta, psi are the 3 orbital paramaters, longtitude of ascending node, inclination and argument of periapsis. You just have to be careful with the conventions. The reason that I didn't add inclination is that would make it difficult to complete the goals.

In case you didn't notice I have uploaded the code in GitHub.

 

Thanks, I'll look into that! Ah, yes, I can imagine another dimension would make it way too hard to play. Those NASA guys have pretty impressive aiming.
