hello,
i'm using reacTIVision to activate playing different songs. i got it to successfully play 1 song when it reads the fiducial marker, and i can interrupt the song with another song when i change it to a different marker, which plays but i also get an error. is it in the placement of my stop and plays? i would like to be able to add more songs later as well for the specific markers in the code. thanks!


here's my code:


import tuio.*;
TuioClient tuioClient;

//IMPORT MINIM LIBRARY
import ddf.minim.*;

//AUDIO VARIABLES
Minim minim;
AudioPlayer player;

//Minim minim2;
AudioPlayer player2;


float cursor_size = 15;
float object_size = 60;
float table_size = 760;
float scale_factor = 1;
PFont font;

void setup(){
 size(600,400);
 noStroke();
 fill(0);
 
//LOAD SWEET TUNES
  minim = new Minim(this);
   // load a file, give the AudioPlayer buffers that are 2048 samples long
 player = minim.loadFile("thismustbetheplace(naive melody).mp3", 2048);
 player2 = minim.loadFile("AbsolutelyCuckoo.mp3", 2048);
 
 loop();

 //fonts
 hint(ENABLE_NATIVE_FONTS);
 font = createFont("Arial", 18);
 scale_factor = height/table_size;

 tuioClient  = new TuioClient(this);
}

void draw(){
 background(255);
 textFont(font,18*scale_factor);
 float obj_size = object_size*scale_factor;
 float cur_size = cursor_size*scale_factor;

 //GET TUIO OBJECTS
 TuioObject[] tuioObjectList = tuioClient.getTuioObjects();
 for (int i=0; i<tuioObjectList.length; i++) {
   TuioObject tobj = tuioObjectList[i];  
   stroke(0);
   fill(0);
   text(""+tobj.getFiducialID(), tobj.getScreenX(width), tobj.getScreenY(height));
   

   if (tobj.getFiducialID()==0){
     fill(255, 0, 0 );
     rect(0,0, 50, 50);
     
  // play the file/////////////////////////////
    player.play();
 
   }
   
   else
     if (tobj.getFiducialID()==106){
     fill(0, 100);
     rect(40,40, 100, 100);  

  //play another file///////////////////////////////
     player2.play();
     stop();
     
     
   }
   else
     if (tobj.getFiducialID()==87){
     fill(0);

   else
     if (tobj.getFiducialID()==98){
     fill(#cccfff);
     rect(40,40, 100, 100);
   }


 }

 //GET TUIO CURORS
 TuioCursor[] tuioCursorList = tuioClient.getTuioCursors();
 for (int i=0;i<tuioCursorList.length;i++) {
   TuioCursor tcur = tuioCursorList[i];
   TuioPoint[] pointList = tcur.getPath();
   if (pointList.length > 0) {
     stroke(0,0,255);
     TuioPoint start_point = pointList[0];
     for (int j=0;j<pointList.length;j++) {
       TuioPoint end_point = pointList[j];
       // line(start_point.getScreenX(width),start_point.getScreenY(height),end_point.getS
creenX(width),end_point.getScreenY(height));
       start_point = end_point;
     }
     stroke(192,192,192);
     fill(192,192,192);
     ellipse( tcur.getScreenX(width), tcur.getScreenY(height),cur_size,cur_size);
     fill(0);
     text(""+ tcur.getFingerID(),  tcur.getScreenX(width)-5,  tcur.getScreenY(height)+5);
