eulerAngles 0-360 Limit Problem

Questions & Answers

Hi,
I am working on an editor script, whenever the user changes an objects rotation, I store the rotation value in a variable. I know I shouldn’t read from Quaternion.eulerAngles but do I have any other option? When an angle is -10 eulerAngles returns it as 350 and I need store it as -10. What should I do?

I solved my problem by doing some math to extract the angles from Quaternion through a custom function. You can google and find the equations needed.

This is what standard asset MouseLook uses :

Quaternion ClampRotationAroundXAxis
(Quaternion q, float minAngle, float maxAngle)
{
    q.x /= q.w;
    q.y /= q.w;
    q.z /= q.w;
    q.w = 1.0f;

    float angleX = 2.0f * Mathf.Rad2Deg * Mathf.Atan(q.x);

    angleX = Mathf.Clamp(angleX, minAngle, maxAngle);

    q.x = Mathf.Tan(0.5f * Mathf.Deg2Rad * angleX);

    return q;
}
