Hi, I have a question about sound buttion of this code.

I want it to start sound if I click the button and the sound will repeat until I click the button again (If I click the button again, then it has to stop)

I've tried this code if I click the button the sound keeps coming out even though I pressed it again.

How do i have to change?

my code:

1. 
   
2. import controlP5.*;
   import ddf.minim.*;
3. //Minim declaration
   Minim minim;
   AudioPlayer player;
4. ControlP5 cp5;
5. int myColor = color(0);
6. 
   void setup() {
     size(1024,768);
     cp5 = new ControlP5(this);
      minim = new Minim(this);
     
     // replace the default controlP5 button with an image.
     // button.setImages(defaultImage, rolloverImage, pressedImage);
     // use button.updateSize() to adjust the size of the button and
     // resize to the dimensions of the defaultImage
    
     cp5.addButton("buttonA")
        .setPosition(175,575)
        .setImages(loadImage("Arrow-Left.png"), loadImage("Arrow-Right.png"), loadImage("Refresh.png"))
        .updateSize();
       
         cp5.addButton("buttonB")
        .setPosition(275,575)
        .setImages(loadImage("Arrow-Left.png"), loadImage("Arrow-Right.png"), loadImage("Refresh.png"))
        .updateSize();
       
         cp5.addButton("buttonC")
        .setPosition(375,575)
        .setImages(loadImage("Arrow-Left.png"), loadImage("Arrow-Right.png"), loadImage("Refresh.png"))
        .updateSize();
       
         cp5.addButton("buttonD")
        .setPosition(475,575)
        .setImages(loadImage("Arrow-Left.png"), loadImage("Arrow-Right.png"), loadImage("Refresh.png"))
        .updateSize();
       
        cp5.addButton("buttonE")
        .setPosition(575,575)
        .setImages(loadImage("Arrow-Left.png"), loadImage("Arrow-Right.png"), loadImage("Refresh.png"))
        .updateSize();
       
        cp5.addButton("buttonF")
        .setPosition(675,575)
        .setImages(loadImage("Arrow-Left.png"), loadImage("Arrow-Right.png"), loadImage("Refresh.png"))
        .updateSize();
       
        cp5.addButton("buttonG")
        .setPosition(775,575)
        .setImages(loadImage("Arrow-Left.png"), loadImage("Arrow-Right.png"), loadImage("Refresh.png"))
        .updateSize();
   }
7. void draw() {
     background(myColor);
   }
8. public void controlEvent(ControlEvent theEvent) {
     println(theEvent.getController().getName());
     String buttonName = theEvent.getController().getName();
    
     //load the file depends on button
     if(buttonName == "buttonA"){
        player = minim.loadFile("1vol.wav");
     }else if(buttonName == "buttonB"){
         player = minim.loadFile("2vol.wav");
     }
     //play
     player.play();   
   }
9. // function buttonA will receive changes from
   // controller with name buttonA
   public void buttonA(int theValue) {
     println("a button event from buttonA: "+theValue);
     myColor = color(20);
   }
10. public void buttonB(int theValue) {
      println("a button event from buttonB: "+theValue);
      myColor = color(50);
    }
11. public void buttonC(int theValue) {
      println("a button event from buttonC: "+theValue);
      myColor = color(80);
    }
12. public void buttonD(int theValue) {
      println("a button event from buttonD: "+theValue);
      myColor = color(120);
    }
13. public void buttonE(int theValue) {
      println("a button event from buttonE: "+theValue);
      myColor = color(160);
    }
14. public void buttonF(int theValue) {
      println("a button event from buttonF: "+theValue);
      myColor = color(210);
    }
15. public void buttonG(int theValue) {
      println("a button event from buttonG: "+theValue);
      myColor = color(250);
    }
