HTML5 - Programming Assignment #1

For this assignment you’ll be combining examples 13 and 14 from the book into a tech demo (still not actually a game).

While they are both good examples that demonstrate some of the basic features of the <canvas> element and its 2d context, they suffer from a few deficincies. Fix these as you rewrite and combine them. Do as you see fit, you’ll be expanding on these examples for the second homework (HTML5 - Programming Assignment #2), so better to code well now than suffer through bad code later.

Use FLOSS development practices while working on this. From the start, keep your code in a git repository linked to github. “Commit early and commit often.” You’ll need to create a new repository on github for this.

As far as combining the examples goes, your demo will need to feature the ability to:

  • Place and destroy buildings.

As far as fixing up deficiencies, you need to:

  • Move all javascript out of the <script> tags and into its own .js files. Your main page can still have one or two javascript make calls to initialize your demo.
  • Convert the code from a half-procedural/half-object-oriented pattern to be fully object-oriented. You should have differenet objects here and not just cram everything into the Game object from example 14.
  • Replace the event handling and listening with jQuery.
  • Replace the style attribute manipulation on DOM elements outside the <canvas> element also with jQuery.
    • For example, the lines where they set className = null and use .setAttribute(...) are so five years ago.

Deliverable

Write a blog post explaining what changes you made and why you made them.

Simply include a link to your github repository for proof of your work.

Optional - use a framework

You may, if you like, move ahead and use a javascript game framework instead of jQuery and the examples from the book. Your project will need to have the same functionality as if it were composed of the two examples, but this will require a larger rewrite (although with much cleaner, denser code). Definitely make note of this in your blogpost if you choose this route.

Here are some examples of frameworks you could use:
