Why does values of eulerAngles not match Rotate transform?

Questions & Answers
1

I have code where I'm rotating a part of an airplane like this:

rAileron.transform.Rotate(-5.0, 0.0, 0.0); print(rAileron.transform.eulerAngles.x);

and I get printed values like this:

278.6123 282.1982 286.5277 291.149

However, when I rotate the other way, +5, the eulerAngles.x values are still increasing like when I rotated -5:

rAileron.transform.Rotate(5.0, 0.0, 0.0); print(rAileron.transform.eulerAngles.x);

which prints:

278.6123 282.1981 286.5276 291.1488

What am I missing here? The part rotates correctly visually, but the values don't add up for me.

It could be because the Rotate function, as you're using it, rotates around the aileron GameObject's local X coordinate, but the eulerAngle values that you're reading out shows the rotation values relative to the world axes.

However, it's best to avoid using eulerAngles altogether wherever possible - and particularly the case of reading the euler values back out and expecting to do anything useful with them is a recipe for disaster!
