Hi,

I’m searching to make a static class of an object.

No problem with a simple sprite :

```
class Arcade extends Phaser.Physics.Arcade.Sprite {
	constructor(scene, x, y, texture) {
		super(scene, x, y, texture)
		scene.add.existing(this)
		scene.physics.add.existing(this)
	}
} 

```

but for a static object like :  
`atari = this.physics.add.staticImage(400, 300, 'atari');`

this code don’t woks :

```
class Static extends Phaser.Physics.Arcade.StaticImage {
	constructor(scene, x, y, texture) {
		super(scene, x, y, texture)
		scene.add.existing(this)
		scene.physics.add.existing(this)
	}
} 

```

How do you do to create a class with a static Image ?

Thanks

Hi @espace,  
The **existing** method of `Arcade.Factory` has an optional second param **isStatic** for this purpose.  
More info in the [docs](https://photonstorm.github.io/phaser3-docs/Phaser.Physics.Arcade.Factory.html#existing__anchor)

Regards.

Sorry but i don’t understand, i try this :

```
class Static extends Phaser.Physics.Arcade.Factory {
	constructor(scene, x, y, texture) {
		super(scene, x, y, texture)
		this.isStatic = true
		scene.add.existing(this)
		scene.physics.add.existing(this)
	}
}

```

but it doens’t works.

Don’t worry @espace .  
The `Arcade.Factory` object is the same as the [add](https://photonstorm.github.io/phaser3-docs/Phaser.Physics.Arcade.ArcadePhysics.html#add__anchor) property of the physics plugin.  
In a nutshell, what I wanted to say was this:

```javascript
scene.physics.add.existing(this, true) // Adds static body
scene.physics.add.existing(this, false) // Adds dynamic body (default)

```

Regards.
