A finished pixel avatar game: a pixel-art character on a colored stage, catching icons drawn from arrays.

Badge requirements: the 5 steps

  1. 1Create an avatarPlan itAn avatar is the character that stands for the player in a game. Design yours as pixel art: a small grid where every square is one color.
  2. 2Use arrays to create imagesIn GlassboxComputers store pictures as lists of numbers or letters. Put your avatar into code: an array of 8 rows, one letter for each pixel.
  3. 3Write an array for an iconIn GlassboxNow write an array from nothing: an icon for something your avatar collects, like a coin, a heart, a seed or a water drop.
  4. 4Develop a game scenarioIn GlassboxEvery game has a scenario: who the player is, where they are, what they try to do and what makes it hard. Write yours, then make your avatar move.
  5. 5Play your gameIn GlassboxMake it a game: when your avatar touches the icon, score a point and send the icon somewhere new. Then play it, and watch someone else play it.
Glassbox: blocks on the left, the art.js file as blocks in the middle with the avatar's 8 rows, the game on the right.
Each step shows how Glassbox works, then opens it with a checklist that ticks as the work gets done.

Work on a computer. The apps need a keyboard and a bigger screen than a phone: a laptop, desktop or Chromebook. You can pay here and open the emailed link on the computer.
