Play a sample when an ellipse disappears

Lou93

Hi there,

This is probably something very simple, but I just can't make it work grrrr. So hopefully someone can help me out!

I have a client patch who registrates the mic input. At a certain amount of mic input, there appear ellipses (bubbles) in the server patch. When they 'float' out the screen, I want to play a sample of a popping sound (like the bubble pops when it isn't in sight anymore). But for some reason this isn't working as I would want to.

Scenario 1: I only use "sample1.play" > the sample sounds 1 time when the first bubble disappears. But if other bubbles disappear, the sample does nothing.

Scenario 2: So I thought maybe I should first say "sample1.rewind" and then "sample1.play" > but then, as soon as bubble 1 disappears the sample keeps rewinding itself from the first second so you have this very annoying crackling sound ALL the time.

So I guess I have to find out how I can let the sample play completely untill it's done and THEN let it start over again as soon as another bubble floats out the screen.

Ik tried to explain my problem as clear as I could! Here is the code:

Chrisir

(not tested)

have boolean nowPlaying = false;

when starting the song say

nowPlaying = true; 
sample1.play(); 

then

if (nowPlaying && ! sample1.isPlaying())  {
    sample1.rewind();
    nowPlaying = false; 
}

that should make it possible to rewind only when the song is over

Lou93

When I put it like below, it still doesn't play again when the next bubble goes away unfortunately..

void outOfBox(){
   
   boolean nowPlaying = false;
   
 if (bubbleX < 0){
   sample1.play();
   
   if (nowPlaying && ! sample1.isPlaying())
   sample1.rewind();
   sample1.play();
}
 }

Chrisir

when starting the song say nowPlaying = true;

Chrisir

have this

  boolean nowPlaying = false;

before setup()

Lou93

Like this? That doesn't change a thing (sorry if I'm misunderstanding you, I'm a noob you see..)

 
 void outOfBox(){
   
   boolean nowPlaying = false;
   
 if (bubbleX < 0){
   nowPlaying = true;
   sample1.play();
   
   
   if (nowPlaying && ! sample1.isPlaying()) {
     sample1.rewind();
     nowPlaying = false;
     sample1.play();
     
}
 }
  } 

Lou93

Oh wait

Lou93

With that line before setup it still doesn't replay ..

Chrisir

hm... I should test this someday

but isn't the idea:

• when a bubbles goes away play a sound. Sounds ends.

• Next bubble, next sound (rewind, play).

• when a bubbles goes away play a sound. When the next bubbles goes off while the sound is still playing, stop, rewind, play from start

?

;-)

Chrisir

before setup()

   boolean nowPlaying = false;

then

    void outOfBox(){



     if (bubbleX < 0) {

       if (nowPlaying && ! sample1.isPlaying()) {
         sample1.rewind();
         nowPlaying = false;
         sample1.play();

        } // if
         else ( ! nowPlaying) {
           nowPlaying = true;
           sample1.play();
        } // else 

    } // if
    } // func

Lou93

Yeah that is exactly the idea. But then just with 1 sample.

Am I typing something in the wrong order?

Chrisir

before setup()

boolean nowPlaying = false;

then

void outOfBox(){

   if (bubbleX < 0) {

     sample1.rewind();

     sample1.play();
     } // if
} // func

Chrisir

I don't know

Lou93

when you put .rewind first he's going to keep starting the sample over and over again. Annoying problem! It should be so easy, but for some reason it's not -.-'

Chrisir

when you put .rewind first he's going to keep starting the sample over and over again.

wait, but outOfBox() is called only once, when the bubble is exploding or is it called again and again?

Chrisir

did you try my code from 03:45?

Chrisir

void outOfBox(){



 if (bubbleX < 0) {

   if (nowPlaying && ! sample1.isPlaying()) {
     sample1.rewind();
     nowPlaying = true;
     sample1.play();

    } // if

   else if (nowPlaying && sample1.isPlaying()) {
     sample1.rewind();
     nowPlaying = true;
     sample1.play();

    } // if

     else if ( ! nowPlaying) {
       nowPlaying = true;
       sample1.play();
    } // else 

} // if
} // func

Lou93

outOfBox() is being called again and again. And yes I definitely tried your code from 03:45.

I get this error when I try your last code

else ( ! nowPlaying) {

unexpected token: {

I tried to put '()' after nowPlaying, but that didn't help.

Chrisir

 else if ( ! nowPlaying) {
       nowPlaying = true;
       sample1.play();
    } // else 

Lou93

Aaaah! I swapped a few lines and now it works! :D

Thank you so much!

Chrisir

great !

Chrisir

can you post the code - might be useful for others

;-)

Lou93

Yes of course!

Above void setup()

boolean nowPlaying = false;
   

And then

void outOfBox(){ 
 
 if (bubbleX < 0) {
 
   if (nowPlaying && ! sample1.isPlaying()) {
     nowPlaying = true;
     sample1.play();
 
    } // if
 
   else if (nowPlaying && sample1.isPlaying()) {
     nowPlaying = true;
     sample1.play();
 
    } // if
 
     else if ( ! nowPlaying) {
       nowPlaying = true;
       sample1.rewind();
       sample1.play();
    } // else 
 
} // if

} // func  

Thanks again Chrisir! This made my day ;)

Chrisir

thank you!
