Hi - the yaw is working fine here. Which version of Oolite are you running?

Which version of Oolite are you running?

And what platform are you running it on?  Windows, Mac or Linux?

It might help if you could post a copy of the Latest.log from the game also.. if you don't know where to find it, once we know what platform you use, we can tell you where it's located.  Post it between 'code' tags, please.. (the little blue <> icon in the post editor window)

I am running this on osx started with version 1.77.1 and attempted 1.76.1 and had the same problem. it may have something to do with it i am not sure but i happened to have a ps3 controller hooked up when it stopped working it was plugged it both well before and after the event.

Ahh... you have Strict Mode enabled, yes? Yaw is not available in Strict Mode.

I'd do a complete fresh install of 1.77.1 too, btw.

I am such an idiot sometimes i cannot thank you enough you saved my sunday 😛

Cool!

That's excellent news.. I love it when problems are easily fixed..

Could you mark the topic as [Solved], please?
