Question How to stop game for a few seconds?

Hey, I don't know anything about game development and I started to watch 'How to do snake game in Unity' video on youtube and I want to do some modifications to my project to learn development.

In this tutorial, if snake will get trigger with obstacles, game will reset and snake is restarting at the initial position immediately. I want to add some audio when the snake is dying, so I want to add a few seconds long cooldown to recreate the snake at the initial position after dying.

Here is the code :

private void ResetState()
{
for (int i = 1; i < _segments.Count; i++)
{
Destroy(_segments.gameObject);
}
_segments.Clear();
_segments.Add(this.transform); //I want this code wait for a few seconds//
this.transform.position = Vector3.zero;
}

Thanks already for your help, if you explain "Why did you write that code?", "What would this code do?" it will help me more.

Sorry for bad grammar.

 

Best way to do this is to use Coroutines https://docs.unity3d.com/Manual/Coroutines.html.
Your reset fonction should be like this.

Code (CSharp):

1. private IEnumerator ResetState()

And you call it like that.

Code (CSharp):

1. StartCoroutine(ResetState());

This way you can wait inside your coroutine by using

Code (CSharp):

1. yield return new WaitForSeconds(1f);

 

As @LilFire points out, the general purpose go-to is a coroutine.

To avoid sprinkling tons of micro coroutines around, I like to use this construct:

I use my CallAfterDelay class for delayed action.

See usage notes at bottom below gist code.

 

Nice!
