Here’s my code.

```auto
int canvasWidth = 800;
int canvasHeight = 600;
int i=0;
void setup() {

    surface.setResizable(true);
}

void draw() {
  circle(100,100,100);
  i++;
  println(i);
}

void settings() {
  size(canvasWidth, canvasHeight);
}

```

Hello @Nokuraion,

Your _draw()_ is working! Windows 10 and Processing 4.3 used here.

For each cycle of draw() you are:

- drawing a circle with a fixed size and location painting over the last one
- updating _i_ and printing it to the console. This means it is working!

An excellent resource for beginners:

Your code works as is here with Windows 10 Pro and Processing 4.3

Please provide more information:

Operating system?  
Version of Processing?

Does the example in the reference work?
