Hello Boss :)

I didn't reach Mike, so I thought I may ask you.
I never did something with spritesheets before, so I'd like to ask you how I should extract the bullets from the spritesheet. Should I count the pixels and then put them in a sprite array or what?

Thank you for the answer

Hello :)

I have a question about how I could access the player who shot the asteroid from Asteroid.js (hit function). Is there something I can do over app.?

Thank you

I have loaded the sounds using this.loadSounds() in App.js but when I go to call this.playSound("shoot"); in Player.js I get the following console error

TypeError: this.playSound is not a function

Hi I'm having trouble getting the coins to animate (and your subreddit has been archived so I can't comment there).

I'm assuming I have to update the sprite in the step function, here's what I've got so far...

var new_sprite = [];
var index = this.sprites.indexOf(this.sprite);

if (index+1 <= this.sprites.length) {
  new_sprite = this.sprites[index+1];
} else {
  new_sprite = this.sprites[0];
}

This didn't work, I have also tried the following:

var sprite_index = this.sprites.indexOf(this.sprite);
this.sprite = (sprite_index+1 <= this.sprites.length) ? this.sprites[sprite_index+1] : this.sprites[0];

I use this.sprite in a drawReqion call in my render function.

Both methods give me the following error:

CanvasQuery.js:438 Uncaught TypeError: Cannot read property '0' of undefined

Any tips on how to do this? you're playground.js docs talk about using an Atlas, but that doesn't seem relevant to this example.
