HI, I am new to Phaser and I have been trying to add change from gameState.something to this. something because when I add a scene to my game file the gameState command does not work any more.  
this is what make the command work, const gameState = {}  
but when I add a scene to the game file with the const gameState = {} it is marked as a error and crashes the game. If it is possible I would like to keep the scene becasue it is what makes the button connect to the game

here is the code that does not work

```javascript
class first extends Phaser.Scene {
  constructor() { super("play"); }
function preload() {

this.load.image('cell', './resources/scriptJS/assets/cell.png');
this.load.image('background', './resources/scriptJS/assets/background.jpg');
this.load.spritesheet('spaceP', './resources/scriptJS/assets/spritesheet.png', { frameWidth: 122.4, frameHeight: 136 });
this.load.image('lava', './resources/scriptJS/assets/lava.png');
this.load.spritesheet('tile', './resources/scriptJS/assets/tiles.png', { frameWidth: 128, frameHeight: 128 });
this.load.image('platform', './resources/scriptJS/assets/platform.jpg');

this.load.spritesheet('enemy', './resources/scriptJS/assets/enemy1.png', { frameWidth: 65, frameHeight: 75 });
this.load.spritesheet('enemy1', './resources/scriptJS/assets/enemy1.png', { frameWidth: 65, frameHeight: 75 });
this.load.spritesheet('enemy2', './resources/scriptJS/assets/enemy1.png', { frameWidth: 65, frameHeight: 75 });
this.load.spritesheet('enemy3', './resources/scriptJS/assets/enemy1.png', { frameWidth: 65, frameHeight: 75 });
this.load.spritesheet('enemy4', './resources/scriptJS/assets/enemy1.png', { frameWidth: 65, frameHeight: 75 });
this.load.spritesheet('enemy5', './resources/scriptJS/assets/enemy1.png', { frameWidth: 65, frameHeight: 75 });
this.load.spritesheet('enemy6', './resources/scriptJS/assets/enemy1.png', { frameWidth: 65, frameHeight: 75 });
this.load.spritesheet('enemy7', './resources/scriptJS/assets/enemy1.png', { frameWidth: 65, frameHeight: 75 });
this.load.spritesheet('enemy8', './resources/scriptJS/assets/enemy1.png', { frameWidth: 65, frameHeight: 75 });
this.load.spritesheet('enemy9', './resources/scriptJS/assets/enemy1.png', { frameWidth: 65, frameHeight: 75 });
this.load.spritesheet('enemy10', './resources/scriptJS/assets/enemy1.png', { frameWidth: 65, frameHeight: 75 });

```

so as you can see I am using gameState instead of this. I tried changing all of the gamestate things to this and deleting the const gameState = {} but that still did not work.

any Ideas on how to fix this?

This is the right idea. You also need to rewrite the scene in a class structure, like

```javascript
// Abbreviated
class first extends Phaser.Scene {
  constructor() {}

  preload () {}

  create () {}

  update () {}
}

```

Is this correct

```javascript

When I deleted the super like you said so and changed the gameState to this the game had crashed but the code showed no errors.

You still need `super(…)`, I just left it out because I was showing the class skeleton.

```js
class first extends Phaser.Scene { 
  constructor() {
    super('first');
  }
  // etc.
}

```

You should use either variables, e.g.,

```
let lava = this.physics.add.image(2000, 740, 'lava').setScale(2);

```

or scene properties, e.g.,

```
this.lava = this.physics.add.image(2000, 740, 'lava').setScale(2);

```

but you need to be consistent — `lava` and `this.lava` are different references.

If you never use a value outside of a function, use a variable for it.

I fixed what you said, I have another question when I add a collider do I have to write it like this.physics.add.collider(player, tile); or this.physics.add.collider(this.player, this.tile);

You have to use the reference you’ve already created.

```js
this.player = this.physics.add.sprite(285, 600, 'spaceP').setScale(2.2);

// Correct:
this.player.setGravityY(80);

// Incorrect: `player` is an undeclared variable
player.setCollideWorldBounds(true);

```

Most editors can warn you about undeclared variables, that should help.

I fixed what you told me to fix and everything works except the controls so the player can’t move. I’m guessing that it has to do with the code in the update function.

No error in the console? Can you show the current code?

Look in the browser console and you’ll see

> ReferenceError: Can’t find variable: lavaKILL

from this line:

> [@doodleCubeCoder](#):
>
> this.physics.add.collider(this.player, this.lava, lavaKILL, null, this);

There is no variable `lavaKILL`, but there is a scene method `this.lavaKILL`.
