pls repair above code posting,

- by using in processing IDE [ctrl][t]
- and here at the forum editor use for code the

```auto
</> code tag

```

* * *

so it might look like

```auto
void setup() {
  size(500, 500);
}

void draw() {
  my_background();
  my_mushroom();
}

void my_background() { //BACKGROUND GRADIENT START
  int r=0, g=0, b=0;
  for (int i = 0; i< height; i++) {
    stroke(r, i, b);
    line(0, i, width, i);
  }
} //BACKGROUND GRADIENT END

void my_mushroom() {
  fill(#4d3300); //dirt floor
  rect(-1, 360, 500, 500);
  fill(#ffffe6); //mushroom stalk
  noStroke();
  rect(225, 120, 50, 330);
  ellipse(250, 450, 50, 10);
  fill(#c2c2a3); //mushroom head
  bezier(180, 270, 210, -50, 290, -50, 320, 270);
}

```

* * *

ok to your question,  
the head of the mushroom is your

```auto
bezier(180,270,210,-50,290,-50,320,270);

```

if you know already that the idea is to make that variable,  
how you can draw that hard coded?  
a very variable version would use

```auto
int mx, my, mw, mh;

```

like for the outer rectangle of the head.  
after you have that running we talk about the animation.

? is it your idea to use  
[https://processing.org/reference/bezier\_.html](https://processing.org/reference/bezier_.html)  
for the head?
