Ok so running into some frustrations with simple rotating of a kinematic object...

Rotate on Y axis no problem, reported angle goes from 0 to 360 degrees.
Rotate on Z axis and object will rotate completely, but reported angle goes from 0 to 180 before switching to -180 (negative) and then counting back to zero.
Rotate on X axis only goes as far as 89.999 degrees, before getting stuck and rotating the Y and Z axis by 180.

Am I missing something here??? I thought this was working not too long ago but I just went back to version 2021-12-06 and not working there either.

You can use the quaternion commands for getting and making rotations.

I had to overcome same probs with my 3D radar.

BASIC appeared in May 1964. Lightning flashed, the wind roared and the Earth moved.
And nine months later I was born.
So here I am.
I am Basic.
Code is in my genes.

Alternatively don't rely on the angles return by GetObjectAngle. Use your own angles

Would you say that for 2D sprites? I get it now, it is a much better way to handle it. I think you saved tons of work hours for me.

I'm not sure about 2D sprites but I know it's the case for 3D objects/cameras
