How can i activate a script on a character when entering in a trigger zone ?

Question

Hello,

I'm new to programming so i'm having trouble with a script. I can't get my player activate a script that is on himself when he arrives in a trigger zone. i just want that, when my player arrives in a trigger area, a script that is on my player activates and work when i'm on the area, and when i'm not on that particular area stop. The script is a script that activate a shader (the script with the shader is working when i'm just putting it on my player).

Thank you.

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
  
 public class trigger : MonoBehaviour
 {
 void OnTriggerEnter(Collision other)
 {
      if (other.gameObject.tag == "Player")
      {
          Script Chunky = other.gameObject.GetComponent<Chunky>();
          Chunky.enabled = true;
      }
 }
  
 void OnTriggerExit(Collision other)
 {
      if (other.gameObject.tag == "Player")
      {
          Script Chunky = other.gameObject.GetComponent<Chunky>();
          Chunky.enabled = false;
      }
 }
 }

Hi and welcome, For scripts you don't need "Script" in front, just write the actual script name.

 Chunky.enabled = true

This is correct, however I need to see the starting of your "Chunky" script to see how you start your script.

Thank you, I replaced the "Script" by my script name, that is "trigger", now i've got another error, it's written : Script error: OnTriggerEnter This message parameter has to be of type: Collider The message will be ignored.

and

Script error: OnTriggerExit This message parameter has to be of type: Collider The message will be ignored.

Here is the actual state of my script :

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
  
 public class trigger : MonoBehaviour
 {
 void OnTriggerEnter(Collision other)
 {
      if (other.gameObject.tag == "Player")
      {
          trigger Chunky = other.gameObject.GetComponent<trigger>();
          Chunky.enabled = true;
      }
 }
  
 void OnTriggerExit(Collision other)
 {
      if (other.gameObject.tag == "Player")
      {
          trigger Chunky = other.gameObject.GetComponent<trigger>();
          Chunky.enabled = false;
      }
 }
 }

Here is the script of the "chunky" script :

 using Assets.Pixelation.Example.Scripts;
 using UnityEngine;
 
 namespace Assets.Pixelation.Scripts
 {
     [ExecuteInEditMode]
     [AddComponentMenu("Image Effects/Color Adjustments/Chunky")]
     public class Chunky : ImageEffectBase
     {
         public Texture2D SprTex;
 
         public Color Color = Color.white;
 
         private void OnRenderImage(RenderTexture source, RenderTexture destination)
         {
             float w = Camera.main.pixelWidth;
             float h = Camera.main.pixelHeight;
             Vector2 count = new Vector2(w/SprTex.height, h/SprTex.height);
             Vector2 size = new Vector2(1.0f/count.x, 1.0f/count.y);
             //
             material.SetVector("BlockCount", count);
             material.SetVector("BlockSize", size);
             material.SetColor("_Color", Color);
             material.SetTexture("_SprTex", SprTex);
             Graphics.Blit(source, destination, material);
         }
     }
 }
