Station Anchor

[juliangiebel]

About the PR

This PR adds the station anchor. A machine that prevents grids from moving if active.
There is a version that doesn't use power and is indestructible

This PR also abstracts out the charging functionality and ui of the gravity generator into the PowerChargeSystem

Why / Balance

Putting this on the trade station prevents players from moving the trade station

Technical details

Sets grids to static when active

Media

• I have added screenshots/videos to this PR showcasing its changes ingame, or this PR does not require an ingame showcase

Breaking changes

TODO:

Setting the grid to static prevents it from showing up on the shuttle console and it prevents the arrivals shuttle from docking.

Changelog

• add: Adds the station anchor. It anchors stations in space and prevents them from moving.

I thought about this solution for players moving trade station to the main station but...
They can still move the main station to the trade station. And we don't want to anchor the main station.

I came up with the idea that the relative position between trade station and main station should be maintained (ideally via a soft tether). The lore explanation is that main station + trade station use the joint center mass to maintain orbit, which is why they are artificially kept an equal vector from each other.

I mean this is fine as a feature and works as a stopgap solution (it's more difficult to move the main station to the trade station than the other way around) but the underlying problem remains unsolved.

station anchor is being worked on lol

I don't understand. Can you elaborate? What station anchor? The one in this draft? I can see that so I'm commenting on it. If you mean another one then please point me in the right direction.

why did i think this was a comment for another pr

[juliangiebel]

The main station should also be anchored.
Also please move discussions about this to discord or github discussions

We want to anchor the station.

[LordCarve]

We want to anchor the station.

Got it.
I don't think this is an ideal decision, but it also outright solves a lot of problems and complexities so it's probably the smart decision. I'm perfectly fine with it. I was just under the impression that we didn't want to anchor the main station.
Thanks for clarifying!

If possible, please make a shuttle anchor aswell, so that for example nukies can park their shuttle and not be afraid of it floating away.

The sprite looks really cool, but is there reason why the anchor is separate from the gravity generator? Anchoring seems like a reasonable side effect of gravity manipulation, and it would save mappers having to include another structure (that needs to be protected with restricted access?)

Also, making the grid static seems to be causing you some issues, based on your todo list. You can't just increase the mass of the grid to some ludicrously high number, or change its max velocity, rate of acceleration, or friction coefficient, to dampen movement to be effectively zero?

probably because shuttles use gravity generators too

The shuttle console and docking issues appear to be fixed. @juliangiebel let me know if there were other bugs that you encountered. Otherwise, this is ready for review.

Test failure is legit
