I'd like my object to be active only when space key is NOT pressed

Question

Hi, I'm new to Unity and Unity Forums, and I'd like to make my GameObject, called "trou" and well dragged in my inspector, disappear when the space bar is pressed.

But when I run the scene, I press space bar once and my object disappears forever, without being set to active when I unpress the key.

I'm on MacOS, with Visual Studio and Unity 19.4.20f1

I don't know why but I can't create any project with 20 versions, it just creates empty folders.

Thank you for helping me ^^

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class DisplayNone : MonoBehaviour
 {
 
     public GameObject trou;
     // Start is called before the first frame update
     void Start()
     {
     }
 
     // Update is called once per frame
     void Update()
     {
         if (Input.GetKey(KeyCode.Space))
         {
             trou.SetActive(false);
         }
         if (Input.GetKey(KeyCode.Space) == false)
         {
             trou.SetActive(true);
         }
     }
 }

Could it be that you added this code as a component of the same object you are referencing ?

Keep in mind that an inactive gameObject stops executing it's code (since it's not "there" anymore).

I'd recommend creating an object "manager" (or whatever) which will have this code as its component, and then activate and deactivate a different object (cube for example) in the escene.

Bonus Track: Minor recommendations on the update Code

1) Use if-else if you want to check the opposite:

      if (Input.GetKey(KeyCode.Space))
      {
          trou.SetActive(false);
      }
      else
      {
          trou.SetActive(true);
      }

2) Unify it in a single sentence (if it doesn't get too confusing for you):

      trou.SetActive(!Input.GetKey(KeyCode.Space));
