[SOLVED] If no collision for some time do something...

How can I write if statement to do something but only if there is no collision with object for some time?

 

1. Whenever there is collision vartime = 0
2. each cycle vartime = +whatever increment
3. if vartime > whatever threshold then dosomething™, possibly reset vartime or whatever is needed

 

I tried like this:

Code (CSharp):

1. ...
2. private bool keepTiming = true;
3. private float timer = 3f;
4. ...
5. void Update()
6.     {
7. ...
8.        if(keepTiming)
9.        {
10.            timer += Time.deltaTime;
11.        }
12.        if(timer <= 0)
13.        {
14.            collisionCount = 0;
15.        }
16. ...
17. void OnTriggerEnter2D(Collider2D collision)
18.    {
19.        if(collision.CompareTag("Enemy"))
20.        {
21.            keepTiming = false;
22.        }
23. ...
24.  

but it doesn't work. Anyone knows why?

 

You're close... but as @neoshaman said above, actually set the time to zero in your collision.

Also, start the timer at zero.

Then ALWAYS count it up in update, regardless of any flags.

Finally, the only check will be if the timer is above your threshhold, do something.

 

I needed to stop it if enemy spawn in room. It's working perfect now

Code (CSharp):

1. ...
2. void Update()
3.     {
4. ...
5. if(keepTiming)
6.        {
7.            timer += Time.deltaTime;
8.            roomTimer.text = "ROOM TIMER: " + Mathf.Round(timer * 100f) / 100f;
9.        }
10.        if(timer >= 0.05)
11.        {
12.            collisionCount = 0;
13.            playerWasInRoom = true;
14.            keepTiming = false;
15.        }
16. ...
17. void OnTriggerEnter2D(Collider2D collision)
18.    {
19.        if(collision.CompareTag("Enemy"))
20.        {
21.            keepTiming = false;
22.        }
23.        if(collision.CompareTag("Player"))
24.        {
25.            playerInRoom = true;
26.            timer = 0;
27.        }
28.    }
29. ...

Thanks :]
