Question Beginner problem Blink ability cooldown Help Needed

I'm adding a tracer like blink ability and I've tried to add a cooldown to the ability but I can't figure it our, any help would be appreciated
here's the code

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4.  
5. public class Blink : MonoBehaviour
6. {
7.     public float BlinkRefreshTime = 5.0f;
8.     public float distance = 5.0f;
9.     void Start()
10.     {
11.        
12.     }
13.  
14.  
15.     void Update()
16.     {
17.         if (Input.GetAxis("Blinke")!=0)
18.         {
19.             BlinkForward();
20.         }
21.     }
22.     public void BlinkForward()
23.     {
24.        
25.         RaycastHit hit;
26.         Vector3 destination = transform.position + transform.forward * distance;
27.        
28.         if (Physics.Linecast(transform.position, destination, out hit))
29.         {
30.             destination = transform.position + transform.forward * (hit.distance - 1f);
31.            
32.         }
33.  
34.         if (Physics.Raycast(destination, -Vector3.up, out hit))
35.         {
36.             destination = hit.point;
37.             destination.y = 0.5f;
38.             transform.position = destination;
39.            
40.         }
41.        
42.     }
43. }
44.  

if you need anything else, please, just ask.

 

Code (CSharp):

1. public float timeOfLastBlink;

When blinking:

Code (CSharp):

1. timeOfLastBlink = Time.time;

To check if you can blink again:

Code (CSharp):

1. if (Time.time > timeOfLastBlink + BlinkRefreshTime)

 

so now using this code where can I change the amount of time it will take to have the ability cool down?

 

Nevermind I'm so stupid, I just looked and figured it out

 

thanks for helping me out man, it helped a lot

 

That's the "BlinkRefreshTime" variable.
