Inertial Dampeners aren't working properly

Raptor2213 shared this bug ago

Reported

Fired up the game, and fired up one of the test ships. Turned off inertial dampers so I didn't have to keep holding down the thrust button. Went out a ways and then turned around and came back. Lined it up and hit thrust again. Found my trajectory to be drifting off to the side, so held down forward thrust and turned dampers on - still drifting without correction. In SE1, turning Dampers on while holding down a thrust direction would normalize the remaining thrust.

You can see the ship 'drifting' to the side, even with Dampeners on.

Potential issue with ship momentum calculations

When moving at high speeds towards a direction, if I let the ship slow down using its inertia dampeners while rotating the ship (no input from keyboard), the ship seems to gain speed sideways.

One way to easily replicate this is to fly away straight from starter asteroid in ship with powerful thrusters in one direction but weak in other directions. Then when max spead reached release throttle and turn the ship towards the asteroid. This at least for me gives the ship sideways momentum.

SE2: Thrust Dampeners not functioning properly based on cockpit orientation

Seemingly I've unfortunately discovered that my thrust dampeners do not function properly on my small ship. Whenever I turn my ship while holding W or S to go forward or backward, the left and right (port/starboard) facing thrusters do not dampen the sideways motion UNTIL i take my finger off the W key. I then found if I place a new cockpit but make it facing a new direction degrees, the dampeners then function properly.

See attached video where I enter my fighter and only press W while turning the ship. You'll notice the left and right thrusters are not firing to stop the sideways momentum until i take my hand off the W key. I then place a new cockpit but facing the left and the thruster dampeners function properly as they should.

I have tried this on multiple worlds. Have been able to replicate it on other ships by placing a cockpit block facing sideways and testing the dampening..

Is there anyway to fix this other than having to rebuild my ship in a new orientation?

I have the same bug

Hello Raptor2213,

I suspect that what you experienced might be due to the ship itself rather than Inertial Dampeners. Blue Ship AE-1 which you have used in the video is a big ship and its side thrusters are not strong enough to compensate changing direction in short time on full speed.

Please try the same scenario as in video with Blue Scout N-S1 which is available to subscribe in KeenSWH Steam workshop.

No, you can clearly see that they just aren’t firing. Also, if this was an issue with them taking time to compensate, you’d see the drift slowly getting better. The drift was consistent throughout.

Hello Raptor2213,

Please use the contraption in the save file I've provided. I used it to check for drift on my end. Please record new video from this try.

Seems to not be an issue with small grids. I did another test with a different large ship and this time when I turned dampeners on, it also killed my forward momentum for some reason - this isn't a thing that any small grid does. This issue ONLY appears to be impacting large grids.

Hello Raptor and keen.

i have this problem too. before i make a ship i have to check in what direction i have to build . i use my thruster test world. i have put it in the workshop. ( no mods world)

its as if the cockpit is not the block that determine the direction of the grid.

Hello All,

Thank you Bart Houseman for sharing a World. :) I have reproduced the issue and reported it internally. I have also added this thread to our internal ticket (SE2-25325).

Hey, I had the same issue on my first playthrough of the new Survival. The ship goes upwards even though I am in gravity and not pressing the space bar. Same for downwards, the this is always at a constant up/down speed. Right/left and backward/forward bugs likewise. After reloading the world, the bug sometime disappeares, I attached the save and a Video of it anyways.

Furthermore, as you can hear in the video, the thrusters are playing their fireing sound and they dont have any flame visuals. Not sure if there are already bug reports on this.

But besides this, awesome work with VS2 Keen!

Hello ATalkingRock,

Could you please provide a blueprint of your affected Grid or the Save File where the issue occurs? Is there anything specific you did while building this ship?

Kind Regards,

Hi! Sure i can attach a link to a blueprint. But I can say, even on the small ships on one of the default worlds, that if you place a new cockpit block essentially pointing to the left or right that ships' left and right dampeners dont function similar to what seen in the vide. Its almost like the grids have a pre-set forward direction which unfortunately doesnt coincide with my ship.

Hey! Just following up, any confirmation that ya'll were able to replicate this?

I have the exact same issue. I can replicate it with any ship. It happens once you deactivate dampeners and after that the dampener don't work like tzey are supposed to. Up and down dampening works, just not sideways. It is quite annoying. If there is anything I can do to help let me know.

I ended up fixing it by completely rebuilding the ship from scratch but tested the grid first that the thrusters would work.

I imagine the cause is when we place a cockpit that doesn't align or point in the direction of the grids "invisible front facing direction"

That may be so but that can't be the solution. This bug happens with any grid. The grid in my example video is from the workshop by diggrock. I hope the devs find a solution. Thx for you reply tho

I mean I definitely agree. It's not an efficient solution by any means
