rotate only on y axis unity code example

Example 1: how to rotate object in unity only on one axis

// If you want the obj to rotate on only one axis do this

// Create vector3
Vector3 target_position = new Vector3(transform.position.x,
                                                target.position.y,
                                                transform.position.z);
// give the target_position to transform.LookAt

transform.LookAt(target_position);

Example 2: look rotation only on y axis in unity

Vector3 relativePos = target.position - transform.position;          Quaternion LookAtRotation = Quaternion.LookRotation( relativePos );            Quaternion LookAtRotationOnly_Y = Quaternion.Euler(transform.rotation.eulerAngles.x, LookAtRotation.eulerAngles.y, transform.rotation.eulerAngles.z);            transform.rotation = LookAtRotationOnly_Y;
