Unity - Clamp Rotation between arbitrary angles

Question

I have a task where I have to clamp an angle between other two angle.

The catch is that the limits can be >360 or <0

(ex. [-4

Answer 1

OK, so I found the solution which clamps the angle correctly in all cases,

Brought to you by Quaternion.Angle() I present :

Quaternion inputAngle = Quaternion.identity;
            if (Character.IsFacingRight)
                inputAngle = Quaternion.FromToRotation(forwardVector, playerInput);
            else
                inputAngle = Quaternion.FromToRotation(playerInput, forwardVector);
            Quaternion minAngle = Quaternion.Euler(0F, 0F, addedForce.force.angle);
            Quaternion angleRange = Quaternion.Euler(0F, 0F, addedForce.force.angleRange);
            Quaternion maxAngle = angleRange * minAngle;

            float roll = (float)Math.Atan2(2.0 * (inputAngle.x * inputAngle.y + inputAngle.w * inputAngle.z), inputAngle.w * inputAngle.w + inputAngle.x * inputAngle.x - inputAngle.y * inputAngle.y - inputAngle.z * inputAngle.z);
            float correctedRotation = roll / Mathf.PI * 180F;

            float minAngleF = minAngle.eulerAngles.z;
            float maxAngleF = maxAngle.eulerAngles.z;

            if (correctedRotation < 0) correctedRotation += 360;

            if (maxAngleF < 0) maxAngleF += 360;

            if (minAngleF < 0) minAngleF += 360;
            if (minAngleF > maxAngleF) minAngleF -= 360;

            if (correctedRotation < minAngleF || correctedRotation > maxAngleF)
            {
                float rotationToMax = Quaternion.Angle(Quaternion.Euler(0F, 0F, correctedRotation), Quaternion.Euler(0F, 0F, maxAngleF));
                float rotationToMin = Quaternion.Angle(Quaternion.Euler(0F, 0F, correctedRotation), Quaternion.Euler(0F, 0F, minAngleF));
                if (Mathf.Abs(rotationToMax) < Mathf.Abs(rotationToMin))
                    correctedRotation = maxAngleF;
                else
                    correctedRotation = minAngleF;
            }
            Quaternion endAngle = Quaternion.Euler(0F, 0F, correctedRotation);
