Question Can't make a sprite be disabled

I'm trying to make a black ball become diable/ activate when you press 'e' on it's light.
but it won't disable at all, nor really come back.

here's what it looks like

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. public class light : MonoBehaviour
5. {
6.    public GameObject darkness;
7.     public bool objactiveon = false;
8.     bool enter = false;
9. void start(){
10. }
11. //diappear the darkness
12.   void Update(){
13.     if (Input.GetKey("e") && enter ){
14.       Debug.Log("This is a log message.");
15.              darkness.SetActive(false);}
16.           }
17.   // check if playes in the box
18. void OnTriggerEnter(Collider hit){
19.       if (hit.CompareTag("Player")){
20.           Debug.Log("This is a log message.");
21.          enter = true;
22.       }}
23. void OnTriggerExit(Collider hit){
24.         if (hit.CompareTag("Player")){
25.            Debug.Log("This is a log message.");
26.            enter = false;
27.         }
28.     }
29.   }

here's the code for it
pls give advice

 

Please use code tags: https://forum.unity.com/threads/using-code-tags-properly.143875/

I recommend liberally sprinkling Debug.Log() statements through your code to display information in realtime.

Doing this should help you answer these types of questions:

- is this code even running? which parts are running? how often does it run?
- what are the values of the variables involved? Are they initialized?

Knowing this information will help you reason about the behavior you are seeing.

 

Everything @Kurt-Dekker said is true.

That being said, if your text is an actual copy of your code, then it appears your update is not capitalized. update should be Update.

 

ok, I put the debug logs in and found that update is working and noathing else. I'll go get pics of the related objects in case there's something wrong with them
edit; also the bool isn't working as well

 

figured it out, I didn't say it was a 2D collider in the code
