Im workingon a P5.js sketch…

Instead of creating objects with a constructor function, and then using the new keyword.

I want to use a factory function.

It seems to work fine, and renders correclty when using for example this code:

```auto
 stroke(255,0,0)
 ellipse(speed, 10, 10, 10)

```

But at the moment i try to use `fill(255)` , i get an error saying fill is not a function?

How is it possible that only this function from p5 is not being recognized but others yes?

Here is a codepen: [https://codepen.io/giorgiomartini/pen/VVKMKg?editors=0011](https://codepen.io/giorgiomartini/pen/VVKMKg?editors=0011)

Code:

```auto
function setup () {
  createCanvas(300,500)
  background(3)
  bola = createCircle(circleOpts)
}

const circleOpts = {
  fill: 255,
  x: 0,
  y: 0,
  maxRadius: 10,
}

const createCircle = ({fill = 255, x = 10, y = 10, maxRadius = 20}) => {
 let speed = 0
 return {
   display() {
     noStroke()
     background(2)
     stroke(255,0,0)
     // if you remove this next line it works!
     fill(255)
     ellipse(speed, 10, 30, 30)
   }
 }
} 

let bola

function draw () {
   bola.display()
}

```

You have fill in the factory definition and fill as a function from p5.js. Rename the first one and your code will work.
