Inertial dampeners cant cope with multiple grids/subgrids.

Isaac Fry shared this bug 16 months ago
Considered

Any craft with the capacity to keep itself in place has the following issue:

Attaching a subgrid via rotor or piston, or any grid via landing gear or connector will cause the main craft to slowly sink or tilt until it falls from the sky.

I have linked a blueprint that shows this with a rotor at the bottom of the post. If you sit the camera very close to the arm on the rotor you can see it slowly dropping. Eventually the craft will tilt too much and fall. You can replace the rotor with a piston with a few blocks on or a landing gear with blocks on. The problem is the same. Attaching a landing gear to one side of the craft can sometimes cause it to even tilt in the wrong direction.

I have also observed the craft continue to tilt slowly even after deleting the rotor or piston. Which may be another issue entirely.


I used a lot of words but essentially: Any craft with rotors or pistons or docking craft cannot remain in a gravity field without eventually crashing.

I would like to clarify that despite a note in the patch notes saying this was fixed, it is not as of 1.187.2

I can see no difference.

I have the same. If I connect, clamp, or otherwise dock a ship into my landing bay, the entire ship grid will slowly list in that direction. I've also noticed that my ship grid, for some reason, keeps moving even when it should be stationary. I often get small grid tremors that end up randomly destroying the landing gear of smaller clamped ships.

Small Hydrogen ship with enough thrust and full tanks - roughly 26t weight.

I attached two solar panels on rotors (thus about 1t more with 2x rotor head, few armor blocks and 2x solar panel)..


Ship with enabled inertial dampeners can't keep altitude by itself despite having full hydrogen tanks and 6 small hydrogen thrusters in right direction (that should be enough for almost 50t).

It would be nice if they fixed this, Perhaps via adding a system that requires you to use your noggin to build ships, You have a thruster on the right of a mass centerpoint, Your ship will veer to the left, and vice versa, up down, left right, back forth.

That would add some much needed depth to this game, Note: rather then needing people to place thrusters perfectly, it would simply throttle down a thuster that would otherwise cause the craft to veer, Meaning, Newbies could still build ships, and they would work (as long as they have at least two thrusters on all sides, and or perfectly balanced their ship) But, It would be more efficient for older players to build ships with mass and center points in mind.


As i said, This is an opportunity to add more depth to the game.

Hello,

I wasn't able to reproduce it with attached blueprint. Could you provide video and confirm it still happens?

Thank you.

Getting video could be hard. I just checked again and its still happening.

Are you sure you got close enough to see it moving? It's very slow. Fly as close as you can, hold the camera still and you can see it slowly move down the screen. Add more heavy blocks to the end of the arm and it will speed up.

If you still can't see it I could try and get video.

I checked it again and I can see small movement, so we created a ticket for it and some programmer will have to look at it. From what I heard it seems to be a problem with Havoc constrains and the fix probably won't be as easy as it seems it could be.

We will inform you here once we have more information.

Thanks! That's all I could reasonably hope for.

I also noticed that the rotation movement can be stopped by overriding gyroscope. Just changing "override gyroscope" checkbox effectively stopped the grid provided above. I know it is not definitive solution, but it could help with parking of this kind of vehicles in gravity until it will be solved.

Still an issue in 1.188.1


Mass attached to a rotor/adv rotor is not compensated for and ship in atmosphere cannot maintain hover on any axis. :[

Still an issue in 1.189.041

see linked workshop blueprint. with the 'guided bombs' hanging on rotors under the wings the damn thing cannot stay aloft. As soon as the bombs are released (detach rotor command set up in upper cockpit) it can hover just fine.

I have the same issue with a ship that has another ship connected via a connector

Still an issue. I worked around it using the Gravity Aligner script, but it's very annoying.

Same issue here :(

This makes a Tug completely impossible since the rate of falling is based on the ratio of mass between the two grids.

Why is this still an issue almost a year after being posted? Extremely aggravating.

Have this bug as well. I added some engines to the second grid past the rotor and that helped some but not 100% fixed.

I've noticed this happening whenever I add or remove a block from a grid. I built a miner awhile back and it hovered just fine but when I ground a block down and it disappeared, the back would tilt a bit, add a block and the same thing happens. And eventually the ship tilted too much and crashed.
