Hi,

I have installed processing 2.0 beta1.

I have copied the toxiclibs library and I get an error:

The package"processing.xml" does not exist. You might be missing a library.

I attached, the sript...

Thanks.

There are two class --> Ball, Shapes

1. import toxi.geom.*;
   import toxi.color.*;
   
   float MAX_SPEED;
   float GRAVITY = 0.3;
   float RESTITUTION = 0.05;
   float JITTER = 0.2;
   float MAX_SPEED = 40;
   
   List<Ball> balls = new ArrayList<Ball>();
   
   void setup() {
     size(680, 382);
     ellipseMode(RADIUS);
     rectMode(RADIUS);
     initBalls();
   }
   
   void draw() {
     background(224);
     noStroke();
     for(int i=0; i<balls.size(); i++){
      balls.get(i).update();
      balss.get(i).draw();
     }
   }
   
   void initBalls() {
    float rnd=random(1);
   if(rnd<0.33){
    balls.add(new Dot());
   }else if (rnd<0.66){
     balls.add(new Square());
    
   } else{
     balls.add(new Heart());
   }
   }
   
   void keyPressed(){
    if(key=='r'){
     initBalls();
    
    }
   if(key=='x' && balls.size()>0){
    balls.remove(0);
   }
    
   }
2. abstract class Ball {

       radius = random(0.25,1)*MAX_RADIUS;
       col=TColor.newRandom();
     }
    
     void update(){
      vel.y+=GRAVITY;
     pos.addSelf(vel);
    if(pos.x<radius){
     pos.x=radius;
     vel.x*=-1;

      vel.scaleSelf(1-RESTITUTION,-(1-RESTITUTION));
      vel.x*=1+random(-1,1)*JITTER;
    }
      
     }
    abstract void draw();
    
   }
3. class Dot extends Ball{
     void draw(){
      fill(col.toARG());
      ellipse(pos.x,pos.y,radius,radius);
     }
    
   }

    }
    
   }
   
   class Heart extends Ball {
    
    Heart(){
      super();
      col=TColor.RED.getAnalog(20,0.5);
    }
    
    
    void draw(){
      Spline2D s = new Spline2D();
      s.add(new Vec2D (0,-0.5));
      s.add(new Vec2D (-0.5,-1));
      s.add(new Vec2D (-1,-0.5));
      s.add(new Vec2D (-0.35,0.35));
      s.add(new Vec2D (0,1));
      List<Vec2D>points=s.computeVertices(8);
      pushMatrix();
      translate(pos.x,pos.y);
      scale(radius);
      fill(col.toARGB());
      beginShape();
      for(int i=0; i<points.size();i++){
        Vec2D p = points.get(i);
        vertex(p.x,p.y);
      }
      for(int i = points.size()-1; i>=0; i=i-1){
        Vec2D p = points.get(i);
        vertex(-p.x,p.y);
           }
           endShape();
           popMatrix();
