How can I make this script work ?

I wanted to create a script to make the camera move after we entered in a box collider. However I'm not very good in programming and I tried to follow another script but it doesn't work, Can somebody help me ? Here is the script. For information, the debug.log doesn't work. Thanks for answering !

using System.Collections; using System.Collections.Generic; using UnityEngine;

public class CameraShake : MonoBehaviour { private bool isShaking = false;

 private float baseX, baseY;
 private float intensity =0.1f;
 private int shakes = 0;


 void OnTriggerEnter2D (Collider2D other) {

     if (other.gameObject.tag == "Player") {
         isShaking = true;
         Debug.Log ("hello");
     }
 }
 void Start ()
 {
     baseX = transform.position.x;
     baseY = transform.position.y;


 }
     
     
     void UpDate () {
     if (isShaking = true) {
         float randomShakeX = Random.Range (-intensity, intensity);
         float randomShakeY = Random.Range (-intensity, intensity);

         transform.position = new Vector2 (baseX + randomShakeX, baseY + randomShakeY);

         shakes--;
     }
         if(shakes<=0)
         {
             isShaking = false;
             transform.position = new Vector2(baseX, baseY);
         }
     }
     


 public void MinorShake(float in_intensity)
 {
     isShaking = true;
     shakes = 10;
     intensity = in_intensity;
 }

 public void LongShake(float in_intensity)
 {
     isShaking = true;
     shakes = 100;
     intensity = in_intensity;
 }

}
