[HELP] ellipses not drawing, things not working...why?

Okay, so I've been trying to generate branches of balls with this code. I've been trying different aproaches since 3 days ago and things do not work for some reason. Please If anyone could take a look I would be very grateful.

`ArrayList galhos = new ArrayList();
float raio_in;
int max_iteracoes = 100;
int it = 0;

void setup(){
size(600,600);
background(170);
raio_in = width/30;
PVector primeira_pos_mae = new PVector(width/2,0);
PVector primeiro_aponta = new PVector(0,raio_in*1,2);
galhos.add(new bgalho(primeira_pos_mae, primeiro_aponta, raio_in, 1)); //EN: generates the first one;

//EN: Debugging to see if its working
noStroke();
fill(255);
ellipse(galhos.get(0).pos.x, galhos.get(0).pos.y, 2*raio_in, 2*raio_in);
println(galhos.get(0).pos);
}

void draw(){

//EN: shows every object
for(int j=0; j 98){
PVector aponta2 = new PVector();
aponta2 = aponta.copy();
aponta2.rotate(random(PI/2-PI/6, PI/2+PI/6));
galhos.add(new bgalho(pos, aponta2, novo_raio, nova_ger));

//EN: debugging to see if it is actually working:
println("lucky!");
stroke(255);
line(pos.x, pos.y, pos.x +aponta.x, pos.y +aponta.y);
}

//depois de proliferar/crescer é mãe
//EN: after it proliferates/grows it becomes a "mother" and no longer does this.
mae = true;
it++;
}

void mostra(){ //EN: show function
noStroke();
fill(0, 255-geracao);
ellipse(pos.x, pos.y, 2*raio, 2*raio);
}

}`
