[Closed] Silly rotation based question?

on bankingSpn changed theState do –spinner that goes from 0 to 180
(
$Cylinder01.rotation.y_rotation = bankingSpn.value
)

It’s fine until it gets to 90 and then goes insane. So when it’s 90.1 that y rotation is 90.101, 90.2 is 89.799 and it just seems all over the place. It’s alright on whole numbers, just not the fractions. Can anyone explain what is going on?

Sounds like your reaching gimbal.

quat / euler | There is a conversion happening… (quaternion has its limits)

$Cylinder01.rotation.y_rotation
-54.9246
$Cylinder01.rotation.controller[2].value
-125.075
(inverse $Cylinder01.rotation) as eulerangles
(eulerAngles -60.2383 -54.9246 180)

That’s amazingly useful, so now I’m using

$Cylinder01.rotation.controller[2].value = bankingSpn.value

And it works perfectly. Also had a look into this Gimbal Lock stuff. x.X

Thanks again!
