unity object rotation script code example

Example 1: unity how to change rotation

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

Example 2: rotation unity script 2d

transform.Rotate(Vector3(0, 0, 50));
//instead of :
transform.eulerAngles = new Vector3 (0, 0, 50);
//or like you said
transform.eulerAngles = Vector3.forward * 50;
