Destroying an object by pressing a key

Hey, everyone!
My problem is very simple: I want for the user to delete a certain object he collides with.
The thing is: Input.GetKey (or its variations) work properly only in Update(), while Destroy(other.gameObject) in this case works properly only in OnTriggerEnter (or its variations).

Here is how I tried to make it work:

Code (CSharp):

1.  void Update()
2.     {
3.         if (GameController.geophoneCount < 3 && (Input.GetKeyDown(KeyCode.G)))  
4.         {
5.             wasDestroy = true;
6.         }
7.     }
8.  
9. void OnTriggerEnter(Collider other)
10.     {
11.        if (wasDestroy)
12.         {
13.             Destroy(other.gameObject);
14.         }
15.  
16.     }

The other strategy I thought was simply creating a Public GameObject in the script and destroying it, which would solve this specific problem, since I only want to destroy the one object, but then, what would happen if I wanted to destroy a thousand different ones?

Is there any way to do it? Thanks.

 

Let's say if only your player can collide with this game object, it's not very complicated. You can set a bool on the script when the player enters the trigger, and set it false upon exit. Now, if that bool is true and the key is down, you can destroy the game object.
Such a script would be on the object you wish to destroy.

I hope that helps

 

You mean by OnTriggerEnter and OnTriggerExit, I did try that one of the times but there was a problem with it.
I'll try again with a different logic and see if maybe it works.
In case it does I'll just post the script in here as an answer.
Thanks for the suggestion, man.
