Unity Nuggets: How to do "Hit Pause" or "Screen Freeze" in games

[@IndieNuggets]

Sorry there is a mistake at 1:03 . This should be "if (_pendingFreezeDuration > 0 && !_isFrozen)" not less than 0

[@TestMyVidsOut]

Love the style of your content, especially that clarification about WaitForSeconds vs. WaitForSecondsRealtime!

[@joe6949]

Just found your tutorial. Great job explaining things! really helpful

[@CoffeeCupPug]

Very good explanation, thank you for this! :)

[@RoroGames03]

Great Video!! Btw there is an error in the Freezer script in the update function it should be if(_pendingFreezeDuration > 0 && !_isFrozen) you typed < 0

[@KevinDrongowskiSmart]

thanks, that was driving me crazy.

[@Maphis11]

Hi there, thanks for posting!

[@uhhh...]

its can apply on player when get hit from enemy?

[@dungensAreDragons]

I would just call Thread.Sleep(25) instead. One line and does that same thing (even easier as it wont mess up any pause or slo-mo script that handle the Timescale)

[@IndieNuggets]

Cool, but wouldn’t thread sleep block the main thread causing everything to stop. There are generally other time independent stuff going around in games which I don’t wanna stop.
Also I’ve found that threads implementation at os level vary wildly.

indian really talent at software

[@roboeast6580]

How would you handle a pause menu (pausing the game) that doesn't conflict with this? If I paused the game during a hit, I am assuming this would break.

[@IndieNuggets]

For pause you can keep another variable like ‘gamePaused’ and if it’s true don’t simulate the game.
I’m not sure what you mean by game breaking but you can always cancel any hit pauses IF/When the game is paused.

[@paradoxicalenigma6119]

Can you please add a tooltip/caption to correct the "if (_pendingFreezeDuration < 0 && !_isFrozen)" ? It can mess many people up since even though it looks weird we still will follow with the expectation that you know something that we don't.

[@IndieNuggets]

Yeah I'm really sorry about that. Seems TH-cam has deprecated the annotations feature so I couldn't add it at the mistake. For now I've added this in the description and tried putting a card at the top. Thanks

[@paradoxicalenigma6119]

@@IndieNuggets Thanks for that! Sorry for sounding critical, I just really liked your video. Other than that the code works great for me, so thanks for your help!

[@dushyantsingh2624]

Thanx a lot bro!! Awesome

[@mathismeilby]

Hi there - when time freezes, I can still move my character which is giving me some trouble. Can anyone help me fix that?

[@DiscipleKnight1010]

Thank you very much

[@aborayan5268]

Thanks for this tuto, really i like your teacher method but one thing please keep this script editor for you next tutos, the new is not good for screen mobile, thank you again

[@spaxhuxley302]

i'm having problems, the script itself doesn't work and I followed you carefully
code:
public class Friezar : MonoBehaviour {
[Range(0f,1f)]
public float duration = 1f;
bool isFrozen = false;
float pendingFreezeDuration = 0f;
// Update is called once per frame
void Update () {
if (pendingFreezeDuration < 0 && !isFrozen)
{
StartCoroutine(DoFreeze());Debug.Log("frez");
}
}
public void Freeze()
{
pendingFreezeDuration = duration;
}
IEnumerator DoFreeze()
{
isFrozen = true;
var original = Time.timeScale;
Time.timeScale = 0f;
yield return new WaitForSecondsRealtime(duration);
Time.timeScale = original;
pendingFreezeDuration = 0;
isFrozen = false;
}
}

[@IndieNuggets]

In your update method "if" condition the "pendingFreezeDuration" should be greater than zero not less than "if(pendingFreezeDuration>0 && !isFrozen)". :)

[@spaxhuxley302]

thank you

[@headbangstudio2443]

I had same problem, thank you.

[@squali1930]

@@IndieNuggets In your video it says < 0 that's why we made the mistake. Thank you for correcting though.

[@JoeAC5000]

You lost me at 2:05 I don't know how to implement any of that stuff.
