My sketch has a smoth function , it works , but there is something , i think is related to the draw function , that makes the shapes look not smooth , altough the line look smooth.

Im new here , i guess what i've told you doesnt really helps you to know where is my problem.

But has everything is code , and i dont know where is the problem i dont know where to poiny you the problem.

How do you explain whats the problem when you have a question ?

Here's the code :

Code:

// setup , configuracion
void setup (){
  background (234,10,98);//fondo rojo
  size(300,300);//tamaño ventana
  smooth();//suvizado
  frameRate (30 );
  cursor(CROSS);
}
void draw(){
  if (keyPressed == true )background(234,10,98); // borrar todo	 
   fill(234,10,98,20);//fade
  noStroke();
   rect(0,0,width,height);
  if(mouseX > width/2){
    strokeWeight(20);
    stroke(#27FF00 ,50);//linea verde
  }
  else
  {
    strokeWeight(20);
    stroke(#E4FF00,50);// linea amarillo
  }
  if(mouseX !=0 && mouseY != 0){//si mouse x e y  no es 0
    line ( width/2,height/2,mouseX,mouseY);// dibujalo
  }
     fill(255);
if(mouseX > width/2){
    strokeWeight(20);
    stroke(#27FF00 );//borde verde de las formas
  }
  else
  {
    strokeWeight(20);
    stroke(#E4FF00);// borde amarillo de las formas
  }     

    

rect(width/4,height/4,width/2,height/2);
ellipse(width/2,230,100,100);
ellipse(width/2,height/5,50,50);
 
}
