Hm, I seemed to get the flippy derping whether or not my cursor was centered; I tested it several times after hitting the V key to recenter my cursor.

I can't reproduce the jerking anymore but I still notice an issue we had in the past.

If you roll left or right with your cursor in the middle, it's fine.

If you roll left or right with your cursor off center, you get weird results. The best I can describe it, is that it also rolls your cursor around the center point...
That's an old issue though, been there for a while but never reported it.

Verified bug.

Please increase the priority because it has become impossible to maneuver ships around docking arms on stations.

Tested various ship sizes and compositions. Only when using a ship with 8 way symmetry in its thruster layout can you achieve normalcy in behavior.

It seems to be dependent on the spacial coordinates of all thuster points in relation to the center of mass of the ship. Asymmetric builds ie more thrusters in the back then in the nose causes the bacon dance. Negligible to an extend on small ships it is impossible to do aileron rolls with large ships. For some reason it also seems to interfere with mouse movement by forcefully moving the mouse cursor outside of the threshold in the center of the screen. The ship will attempt to aim its nose at the cursor thereby moving in what seems like the movement pattern described in the first post. It also issnt restricted by the normal turning potential factor of the ship causing 500+ meter ships to spasm out of control in said directions.

Still happens whether cursor is centered or not.
Makes the game pretty much unplayable.

Also: it's intriguingly much worse in SP.

Can confirm.

Yes, I can confirm this.

Seems like ever since the Thrust update way back when, ships have been wobbling when rolling. Before that we had silky smooth rolling along the Z axis of the ship that only got slower when the ship size went up. Cores alone would whirl around like in a blender, but larger ships had a nice smooth roll instead of wobbing around and making you feel like you're not in control of the ship.

added config option DEBUG_SHIP_CAM_ON_RCONTROL
this will enable testers to see the debug camera. This is basically the view that the ship is trying to align on.

The bug was that on Roll, the camera was rotating around the forward vector of the ship instead of its own forward vector. this is now fixed.

To test this, make sure that the center of mass is where your view is (e.g. on the core). Else you will have trouble filtering out the movement that is induced by rotating around the center of mass.

Be finally gone, filthy bug

fix should be in 0.199.485

Needs some more testing but the severe issues are gone. It's still possible from time to time where it seems to register a 180° flip but not sure yet how to reproduce that consistently.
