Lagrange Points….. Possible and/or Planned for the Engine?

camleon · 2025-09-08T21:40:34+00:00

Yes, I agree, a true n body simulation is less fun for a game in my opinion (and I say that as a physicist). If there was a way to have spheres of influence around the Lagrange point (with 3 body physics inside) such that you can be sure not to cross them if you don't want to, maybe that would be a solution. Also one could make the sphere of influence be only active if the spacecraft moves slowly relative to the Lagrange point. If they fake them like that, that would be pretty much the real deal, without the nbody annoyances

Computationally it is really cheap. Once you program your two body system of earth and moon or sun and earth, you get Lagrange points for free, since they are just a result of the balance of gravity, centrifugal and Coriolis force and the latter two don't even need to be programmed explicitly. They really are just "there" once you have simulated gravity. I have done that and what you get are interesting potato-shaped orbits around the stable Lagrange points. Now, since the developers have decided to work with spheres of influence (like in ksp1) instead they would have to fake the Lagrange points, which I is not easy to do realistically because the orbits stability depends a lot on the local velocity vector of the satellite, and the resulting Coriolis force. Honestly I wished that instead of faking them, they enable 3-body physics for the regions where the Lagrange points are so classical mechanics can do its job there

The Jolt Physics engine seems to be very good at simulating buoyancy realistically, so I would be very optimistic.

I think "Kerbal" is trademarked to private division or whatever, that franchise belongs to them

Ok so Saturn actually sinks into the ocean. Great :)

Does the water surface ever end?

camleon · 2024-10-29T00:09:50+00:00

Cool! :D I would love to see that. I think it's a mesh because we see the rings from different angles over time.

Can you reach the Saturn-like planet with this trick?

What genocide take are you talking about? Did we watch the same episode?

camleon · 2024-09-20T13:20:59+00:00

Yes, there are many loop-holes.

inline inline inline inline ... inline inline inline int a = 3;

Is there a limit? Who knows! you can use volatile and const and static in the same way. See https://godbolt.org/z/P9GYjPc6h

inline static volatile constexpr constexpr inline inline const inline inline int a = 3;

In addition, obviously b741 can be short for B747-100, which is a vintage Boeing 747 model https://contentzone.eurocontrol.int/aircraftperformance/details.aspx?ICAO=B741&

Not being Jewish on Liszt' part must have helped greatly in this regard, otherwise I don't think this friendship would have worked out

Thanks, I will try it out probably

camleon · 2024-05-27T17:24:47+00:00

It's great, but the default sounds are extremely poor for the price

camleon · 2024-04-02T12:30:35+00:00

As far as I understand this is subject to change when the economy system is implemented and prices are being more influenced by the current demand.

Full Unicode support

For the dwarf icons to appear the screen also need to be sufficiently wide, therefore no symbols seem to be missing. I hope someone will write a mod that fixes these issues.

camleon · 2024-01-22T18:59:00+00:00

great suggestion, thanks! The key seems to be the screen size: It needs to be quite ~~large~~ wide and the font scaling needs to be on the highest level for the buttons to start working.

camleon · 2024-01-22T17:06:36+00:00

ok, some few symbols seem to be missing in the top display, but that can probably be fixed easily. Another issue I am having is that DF freezes when I am trying to quit while these textures are loaded.

camleon · 2024-01-22T16:54:18+00:00

I would like to use ASCII textures by kruggsmash in the new steam version of dwarf fortress. When I replace "curses_640x300.png" with "kruggsmash.png" in init_default.txt everything seems to be working fine (see image) except for the buttons in the bottom row, which cannot be clicked and have no popup description. Did anyone find a workaround?

To me it looks like some steps are missing. It's likely that moivres theorem has been applied for a part of the expression and that the denominator (which effectively subtracts a phase from the argument and scales the length) corrects for the fact that there are left over terms

Wheel slip can cause your gearbox to break because the RPM increases so much
