unity clamp rotation using quaternion code example

Example 1: unity clamp rotation

float rotationX = 0;
float rotationY = 0;
// you might also have some rotation speed variable
void Update() {
   rotationX += Input.GetAxis("Vertical") * Time.deltaTime;
   rotationX = Mathf.Clamp(rotationX, minRotationX, maxRotationX);
   rotationY += Input.GetAxis("Horizontal" * Time.deltaTime;
   transform.rotation = Quaternion.Euler(rotationX, rotationY, 0);
 }

Example 2: unity rotation to quaternion

using UnityEngine;public class Example : MonoBehaviour
{
    void Start()
    {
        // A rotation 30 degrees around the y-axis
        Quaternion rotation = Quaternion.Euler(0, 30, 0);
    }
}
