changing the rotation of an object with script Unity code example

Example 1: how to get rotation of object in unity c#

float angleX = myTransformGO.rotation.eulerAngles.x;  
float angleY = myTransformGO.rotation.eulerAngles.y; 
float angleZ = myTransformGO.rotation.eulerAngles.z;

Example 2: how to chagne rotation in unity

transform.eulerAngles = new Vector3(0f, 180f, 0f); // rotates 180 degrees
