01:18 <queqiao-> ⟨clayel⟩ regarding https://discord.com/channels/319857228905447436/319857228905447436/1270851642060963891, i think principia having some maneuver making abilities like mechjeb has would be very helpful for qol and bridging the gap between patched conics and principia

01:18 <queqiao-> imo, the hard part is not dealing with the planning frames, but actually making the maneuver (where previously using mechjeb could make a maneuver in a few seconds)

02:39 <queqiao-> ⟨lamont⟩ that is a very easy opinion to have and a much more difficult opinion to put into code

02:41 <queqiao-> ⟨egg⟩ Indeed. This is what it took to do the local optimizer we have: https://github.com/mockingbirdnest/Principia/issues/3681

02:42 <queqiao-> ⟨egg⟩ But really, this is hiding the bulk of the work, which happened because of https://github.com/mockingbirdnest/Principia/issues/3358; note the considerable list of PRs there.

21:27 <queqiao-> ⟨iamgm1000⟩ For downloading principia you just pop in Principia folder into your gamedata right?

21:27 <queqiao-> ⟨iamgm1000⟩ * the

21:34 <raptop> Yes, though note that you may need some additional dependencies. See https://github.com/mockingbirdnest/Principia/wiki/Installing,-reporting-bugs,-and-frequently-asked-questions for details

21:34 <queqiao-> ⟨iamgm1000⟩ Thanks

22:57 <queqiao-> ⟨iamgm1000⟩ I just downloaded principia and orbit lines aren't appearing anymore just the icons

22:59 <queqiao-> ⟨egg⟩ RSS or stock? In stock, that is normal, the world is new so there is no history to show.

22:59 <queqiao-> ⟨iamgm1000⟩ rss

22:59 <queqiao-> ⟨egg⟩ Screenshot?

23:00 <queqiao-> ⟨iamgm1000⟩ https://matrix.mockingbirdnest.com/_matrix/media/r0/download/matrix.mockingbirdnest.com/nszINnnbnWZaYVfOJqFffFyP/Screenshot_2024-08-10_at_00.59.52.png

23:00 <queqiao-> ⟨iamgm1000⟩ For example this is the moon

23:00 <queqiao-> ⟨iamgm1000⟩ It has a bit then just fades away

23:00 <queqiao-> ⟨egg⟩ Yup, that is normal.

23:00 <queqiao-> ⟨egg⟩ If you want more history, you can increase the history length setting.

23:00 <queqiao-> ⟨iamgm1000⟩ Oh...

23:00 <queqiao-> ⟨egg⟩ I suppose you have read https://github.com/mockingbirdnest/Principia/wiki/Concepts?

23:01 <queqiao-> ⟨iamgm1000⟩ I'll have to mess around with it tomorrow and figure everything out

23:01 <queqiao-> ⟨iamgm1000⟩ Ohh I see so now th orbit lines appear

23:02 <queqiao-> ⟨iamgm1000⟩ Thanks

23:02 <queqiao-> ⟨egg⟩ (The default is 7 days, so a quarter of the Moon’s orbit.)

23:03 <queqiao-> ⟨iamgm1000⟩ https://matrix.mockingbirdnest.com/_matrix/media/r0/download/matrix.mockingbirdnest.com/eiqtjcnVQqYlJqRZMGdiBXVa/Screenshot_2024-08-10_at_01.03.08.png

23:03 <queqiao-> ⟨iamgm1000⟩ Yep now I have much much more

23:03 <queqiao-> ⟨egg⟩ Indeed. But I would like to point out that while this is almost entirely useless; in practice you want to switch reference frames if you want to do anything with the Moon. Please, please, read the concepts page.

23:04 <queqiao-> ⟨egg⟩ +pretty,

23:04 <queqiao-> ⟨iamgm1000⟩ Is there also a reason why my game is extremely laggy compared to before principia?

23:04 <queqiao-> ⟨egg⟩ Because you have just asked for a lot of history to be drawn, so we now have to compute and draw a lot of lines on your screen.

23:05 <queqiao-> ⟨egg⟩ Which, as previously mentioned, is pretty, but not very useful.

23:05 <queqiao-> ⟨iamgm1000⟩ I do also have RSS origin

23:06 <queqiao-> ⟨egg⟩ How many bodies?

23:06 <queqiao-> ⟨iamgm1000⟩ I don't have them all currently but around like 60/70 i'm pretty sure

23:06 <queqiao-> ⟨iamgm1000⟩ the full is 180

23:06 <queqiao-> ⟨egg⟩ « Doctor, it hurts when I do this »

23:08 <queqiao-> ⟨egg⟩ (Some of the computational cost increases linearly with the number of celestials, you just tripled that. Some other computations, which are usually ignorable in terms of cost, increase like the square of the number of celestials, you just multiplied that by nine, so maybe they are not so ignorable either.)

23:09 <queqiao-> ⟨iamgm1000⟩ Then well it's understandable why it's laggy

23:11 <queqiao-> ⟨egg⟩ Indeed. Note that if you want to change the set of bodies, you need to make a new save (Principia actually simulates the motion of the whole thing, it cannot have bodies popping in and out of existence). So maybe tone it down to something you can enjoyably play with. Anyway, if you are learning Principia, it is going to be a while before you get to anything beyond the RSS baseline; already you will find that the Moon is a much more...

23:11 <queqiao-> ... interesting place than it used to, both to get to and to be around…

23:13 <queqiao-> ⟨iamgm1000⟩ Yeah, I will tone it down with the celestials considering this is basically unplayable due to lag

23:15 <queqiao-> ⟨iamgm1000⟩ At least for my computer

23:16 <queqiao-> ⟨iamgm1000⟩ While flying the actual craft it's perfectly fine but when I switch to the orbit view (the one in which I provided the screenshots) every input takes like 1 second to register
