Newb scoping issues

Phaser 3
1

Hey guys, I am working with a tutorial and I want to understand how the sprites are scoped to the Game.

In the create function() I define:
this.car = game.add.sprite(0, 0, ‘car’);

then in the update function() I want to set the visibility based on some logic:
game.paused = true;
this.car.visible = false;

I get a Type Error
TypeError: undefined is not an object (evaluating ‘this.car.visible = false’)

Thanks for the help in advance!

Hello @pmullady

If you are new to Phaser 3 you might want to go through this official tutorial.

If you define the car sprite, you should use the following syntax:

this.car = this.add.sprite(0,0,'car');

I believe you have preloaded your car sprite in the preload() function as follows?

this.load.image('car', './path to your sprite');

To set the Visibility you have to use .setVisible(false)

Hope this helps.

yes, thanks!
I think I may be mixing up code from older Phaser 2 and newer Phaser 3 examples.

Thanks for the quick response! I got it now.

In general in Phaser 3, you should never need to touch the game object. Everything should go through the this reference in the scene.
