Rotor collisions are broken since 1.206

NovaEngie shared this bug ago

Reported

Before 1.206, and for years prior, this worked. And it has plenty of visual clearance. It doesn't rotate the full way around and, in fact, the block always stays inside the outside arc so never even gets close. Could you please fix? Because as it is I cannot work around this. Thank you. c770c456c5a19ba3146b9edb9d1a21fa

Fieldwork Update Small Grid Rotor Displacement Clang

Any small grid rotor that is under -0.4 displacement will start to slowly clang.

This clang becomes more intense if there is any block adjacent to the rotor.

All grids with the lowest possible rotor displacement in small grid have basically begun to spin from clang following the Fieldwork Update.

I have been waiting to see if anyone else would report it first, but I guess I have to be the one to mention it.

While this isn't a game breaking bug, it is very annoying for a lot of us that enjoy using small grid subgrids.

The clang can be pacified by having around 5-6 gyroscopes to fight it, but this makes micro-builds relying on rotor displacement completely unusable.

A fix would be greatly appreciated for a lot of us mech builders and other small grid machine makers :D

Small Grid Rotor Displacement capped at -0.02 and -0.08 - as of 1.206.032

Small grid, small rotor displacement -in both standard and advanced rotors- is limited to -0.02 and -0.08 respectively (image attached). And exceeding these values results in clang, and obviously an inability to rotate.

I don't think anyone was at a deficit for rotor parts being relatively collisionless. And I know their updated hitboxes are breaking nearly half my subgrid builds. Thank you for consideration.

Small grid small rotor base and part collide with each other when set to a displacement of -3cm

The small grid, advanced small rotor base, and part collide with each other when set to a displacement of less than -10cm.

All other rotors are fine

Hello Engineer,

Thank you for your report.

Unfortunately, I wasn't able to reproduce the issue on my end. Could you please provide the blueprint or a video showing the issue? This will help us investigate more effectively and pinpoint the cause.

Thank you for your cooperation!

Best regards,

Here you go. This worked flawlessly for years prior to this update.

Thank you!

I was able to reproduce the issue on v206 and reported it into our system. It will be forwarded to our dev team for investigation.

We will change the status of this topic and inform you about its progress here as soon as we have new information.

Kind Regards

Hello Engineer,

It appears the small grid rotor has an offset issue where, if the offset is too low in the negative, it starts clanging out. We will investigate this further.

That said, this blueprint can be fixed simply by resetting the rotor displacement slider (right-click on the slider), after which the panels appear to work as intended without any further changes necessary. This also resolves the slight spin this blueprint has while in 0G.

Best regards,

This is a bit problematic; it can cause unwanted clang and unpredictable physics. Maybe this could be resolved by making the hitbox slightly smaller on the rotor head side?

Thanks for submitting this for fix. That's an odd one, just it suddenly not liking the lowest rotor displacement for no reason. That probably breaks a LOT of creations. I would never have thought it would be the rotor itself; it only made sense to be the tank's hitbox.

At this point. I am glad I have not touched SE1 since the 'Fieldwork' update. Seems like there are too many bugs and or unnecessary changes to the game, which is a shame.

Oh, building tip I discovered while fixing this: I figured out how to build pseudorotors with hinges and round columns. The columns can either be attached to the back of whatever attaches to the hinge so it rotates on the same axis as the hinge as if it were a rotor, or to the main grid so it stays fixed. So it can be made to appear as if it were on a rotor when, in fact, it's on a hinge. It also gives a smoother driving / walking transition between grids than using blast doors. Basically, it lets you have many of the advantages of a rotor in a hinge.

I get -11 to +11 on 1-206-032. Stable at max velocity of 60rpm.

Interesting!

If it's convenient, could you make a display similar to the one attached? At max -11cm, the rotor head should be quite clipped into the stator. I'd be very confused if this is only for a few people.

Yes this bug has caused 90% of my mech builds to be clangy or constantly shake.

How about this? This doesn't show inline but you can download it and view it there. Looks as I expected it to look. Quite a difference between min and max. Even duplicating the =11cm tilt of yours.

Silly question : Is yours powered? Mine is. Might not do displacement out if not powered.

Yes, powered.

Notice how the head of the rotor in both our images stops at the top of the stator instead of clipping into it like it used to (on the standard rotor; advanced gets lower but in my testing is still unstable when rotating). That point it stops at, at the head of the stator (the static block) is -2cm, not the -11cm that it should be capable of going to. Not to mention the clang it causes.

Thanks for verifying! You do have the same issue.

This bug also happens with the small advanced rotor. Here's an example for both rotors https://youtube.com/shorts/6wCNvF-BJcE?si=fy73WRB_ipwOwS6-
