delay or waiting?

Question

Hi, i'm trying to write up a script that plays an animation when a key is pressed on the screen, and immediately after moves the camera to another location. but i've encountered a problem where the animation will play after the key is pressed and the camera will move at the same time so before the animation even got through the first frame i no longer see it. is there a type of delay or wait method that can allow me to wait 1 second after so i can make the animation visible before moving the camera?

below is the function i've set up for it.

 public void Anime(){
         Instantiate(explosion, touchpos, Quaternion.identity); //explosion animation
         hit.transform.SendMessage("HideMe"); //disable renderer for object
         Instantiate(shatter, hit.transform.position, Quaternion.identity); //shattering animation of object
         //delay script here ??
         MoveCamera();
         hit.transform.SendMessage("ShowMe"); //re-enable render for object
     }

Make it a Coroutine, and then use WaitForSeconds as described in that doc page. Note in C# you'll need to call this function using StartCoroutine(Anime()) instead of a regular function call.

I've never used Coroutine before so im not sure if im doing it correctly, i've got this function that'd wait for 1 second

IEnumerator WaitOneSecond() { yield return new WaitForSeconds(1); }

then i call it in my function with StartCoroutine( WaitOneSecond() ); ? because when i did it this way it didnt delay at all

@wolfram means that you make your whole function an IEnumerator and start Anime using StartCoroutine, then you insert yield return new WaitForSeconds(1); where you have the comment in your code.

oooh okay i got it now, thank you very much. i changed the function into an IEumerator and used StartCoroutine(Anime()); to start it then i realize i needed the line of code that changes camera view to be in the function as well which was causing me the problem.

Ah, sorry I didn't get back to you. Thanks @whydoidoit :-) Also, I wrote "Awake" ins$$anonymous$$d of "Anime"...must have been a reflex...

The idea is, if you use StartCoroutine(...) somewhere, it launches a function which runs separately from the rest of your code, your normal code will continue immediately, directly after the line StartCoroutine(...). Within the coroutine, you can place "yield" statements, to wait for a single frame, or to wait for several seconds, and so on.

for anyone in the future that come across this: my problem was that i assumed that i can have the below script as a function i can call up whenever i needed to have a 1 second delay in my coding.

 IEnumerator WaitOneSecond() { 
     yield return new WaitForSeconds(1); 
 }

like something like this was what i assumed it to be

 void Update() {
     //do some stuff
     StartCoroutine(WaitOneSecond()); //delay for a second
     //continue do some other stuff
 }

But this is incorrect. in the end i had something like this that worked

 IEnumerator AnimeNwait(){    
     Instantiate(explosion, touchpos, Quaternion.identity);
     
     hit.transform.SendMessage("HideMe"); //disable renderer
     Instantiate(shatter, hit.transform.position, Quaternion.identity);
     
      yield return new WaitForSeconds(0.8f);
     _MainMenuCameraShift.SettingisClicked = true;
      yield return new WaitForSeconds(0.8f);
     hit.transform.SendMessage("ShowMe");
 }

and i called this coroutine with StartCoroutine(AnimeNWait()); in the script when needed

$$anonymous$$rHasuu - Hello.

You wrote: something like this was what i assumed it to be void Update() { do some StartCoroutine(WaitOneSecond()); //delay for a second continue do some other stuff

Can you PLEASE show your solution nor from your code but just like you showed as it doesnt work.

Its some kind of a conspiracy. Everybody talking about starting coroutine but nobody show where should be my void update in all of this.

The one has nothing to do with the other. Anything in Update() will be executed each frame, immediately. Anything in a Coroutine will be executed according to its yield commands.

So putting a StartCoroutine() into Update() would launch a new instance of that coroutine every frame, which is almost certainly not what you want. Ever.

Ins$$anonymous$$d, start your Coroutine once, wherever (for example in Start()). If you then feel the need to do something every frame in that coroutine, use a loop with a "yield return 1;" in it.
