Question by youshaa_murhij · Feb 17, 2019 at 06:33 PM · rotationquaternioneuleranglesjoints

Rotation Problem on X Axis over 90 and -90 degrees!

I am using this code below to rotate a joint around x axis from -120 to 120 degrees and everything is working fine from -90 to 90 degrees but if the rotation angle is over 90 or under -90 the joint starts an infinite rotation ...maybe I should change the other axis rotation values ,too ?! I am using this way on Z and Y axis and everything is good.

 if (transform.localEulerAngles.x > 180)
             {
                 ACT = transform.localEulerAngles.x - 360;
             }
             else
             {
                 ACT = transform.localEulerAngles.x;
             }
             d_theta2 = theta_2 - ACT;
             Quaternion originalRot = transform.rotation;
             transform.rotation = originalRot * Quaternion.AngleAxis((float)d_theta2, Vector3.left);
