Hi,
I want to set some code I found to make random stars, but I want to change it so I can control # of spikes and radius with number boxes,

but I havent understand how to accomplish this,
here is the code, Thank you:
 

1. // analizando programa star,
   // donde llama a las classes?
   
   Star star; //
   import controlP5.*;
   
   ControlP5 controlP5;
   
   Textlabel myTextlabelA;
   Textlabel myTextlabelB;
   
   int a = 8;
   
   public int numberboxValue = 10;
   
   void setup() {
     size(800,600);
     //frameRate(30);
     controlP5 = new ControlP5(this);
     controlP5.setControlFont(new ControlFont(createFont("Georgia",20), 20));
   
     myTextlabelA = controlP5.addTextlabel("label","ISHTAR",10,250);
     myTextlabelA.setColorValue(0xffcccccc);
     myTextlabelB = controlP5.addTextlabel("label","IX",20,-250);
     //myTextlabelB = new Textlabel(this,"a single textlabel big stuff.",20,20,400,200);
   
     controlP5.addNumberbox("numberboxValue",0,20,50,80,14);
   
     smooth();
     star = new Star();
   
   }
   
   
   
   void draw() {
     //background(0);
     //myTextlabelB.draw(this);
     fadeToBlack();
     star.draw();
   }
   
   // EMPIEXA kkkkkkkkkkkkkkkkkkkk
   
    
   
   void fadeToBlack(){
     // fade away
     fill(0,0,0, 30);
     noStroke();
     translate(0,0); //centrar??
     rect(0,0,width,height);
   }
    
    
   // ================================================================ separador para las clases?
    
    
   class Star //class 1 notar la mayuscula,
   {
     // define variables, propiedades
     float phase = 0;
     float r1=0, r2=0;
     int spikes=0;
     Point[] points;
      
     Star(){ //constructor, mismo nombre que la clase, no inizialisa pues no hay variables?
       setProps(); //metodo?? cual funcion??
     }
      
     public void draw(){ //porque con nombre draw??
        
       translate(width/2, height/2);
       noStroke();
       //strokeWeight(.5);
       //stroke(255,255,255);
       //noFill();
       fill(255,255,255, 50);
        
      // r1 = 200;
      // r2 = 60;
      // r1 = height * cos(phase);
       //r2 = height/5 * cos(phase);
       phase += .1;
        //r1 = ((width/2) - mouseX) / 10;
        calcPoly();
        render();
        if(frameCount % 60 == 0) setProps();
     }
      
     private void setProps(){
       //spikes = int(random(174))+6;//getNumSpikes();
       spikes = getto();
