back click for reset and double click back for back scene

hi I am new
I am in a problem
in my case, I want to click back, button in the android reset scene and with double back, load the first scene

Code (CSharp):

1.     int click = 0;
2.     void Update()
3.     {
4.         if(Input.GetKeyDown(KeyCode.Escape)){
5.             click++;
6.             StartCoroutine(ClickTime());
7.             if (click > 1)
8.             {
9.                 SceneManager.LoadScene(0);
10.                 Debug.Log("exit");
11.             }
12.             else{
13.                 SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex);
14.             }
15.         }
16.        
17.     }
18.  
19.  
20.     IEnumerator ClickTime()
21.     {
22.         yield return new WaitForSeconds(0.5f);
23.         click = 0;
24.     }

this is my code. first scene never happen
please help me

 

You are reloading the current scene (in the "else" clause, lines 12-14) as soon as the first click happens, without waiting to see whether there will be a second click.

If you want to do different things for single-click and double-click, then you can't actually do the first thing on the single-click, you need to wait and do it once enough time has passed that it's no longer possible for that click to count as the first part of a double-click.

 

sorry, I can't get it
Do you mean this is not possible?

 

Re-read antistone's post carefully:

In other words, you cannot act when the first click comes in. You have to say "oh I have been clicked, start a timer... did I get a second click within the time I need, or if not, then just take it away with the first click."

This is the only way that single-click vs double-click can be determined.

The simplest timer is a float you set to zero, then increment by Time.deltaTime each frame, and check against your limit. Obviously you'd need a boolean to indicate that timing has started from the first click.

 

Code (CSharp):

1. int click = 0;
2.     void Update()
3.     {
4.         if(Input.GetKeyDown(KeyCode.Escape)){
5.             click++;
6.             StartCoroutine(ClickTime());
7.             StartCoroutine(backWork());
8.         }
9.     }
10.  
11.     IEnumerator ClickTime()
12.     {
13.         yield return new WaitForSeconds(0.5f);
14.         click = 0;
15.     }
16.     IEnumerator backWork()
17.     {
18.         yield return new WaitForSeconds(0.4f);
19.         if (click > 1)
20.         {
21.             SceneManager.LoadScene(0);
22.             Debug.Log("exit");
23.         }
24.         else{
25.             SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex);
26.             Debug.Log("reset");
27.         }
28.     }

I changed my code to this and working thank you guys
if anybody sees a bug in code or knows a better code I'll glad to share it with me
