Code Monster from Crunchzilla

How to Play

Code Monster teaches kids and adults a little about Javascript programming!

It's easy to play. Follow the instructions and do what Code Monster says. If you get stuck, just skip to the next lesson. You can always come back to it later!

Click on the Reset button if you really mess up your code and want to start over on a lesson. Click on the Back button to go back to a previous lesson. You can jump to a specific lesson or back to the beginning using the "Lesson Sections" link.

Code Monster saves what lesson you are on, so feel free to stop at any time and come back later. As long as you come back on the same browser on the same machine, you'll get back to your lesson.

Have fun!

About

Code Monster from Crunchzilla is an interactive tutorial for kids that focuses on action. Code changes immediately yield visible results.

Projects start with simple boxes and colors, rapidly progressing into exciting experiments with simple animation and fractals. Important programming concepts like variables, loops, conditionals, expressions, and functions are introduced by example.

Code Monster is a gentle and fun introduction to programming concepts. It is a first step in learning to program. It is not intended to teach all of computer science and programming.

Code Monster is based in Seattle, WA. It is part of the Crunchzilla suite of game and educational projects developed by Geeky Ventures.

Frequently Asked Questions

What is the c in things like c.save()?

It's a little technical but, if you want to know the details, c is a variable Code Monster creates for you that contains the Canvas' 2D context. The code that creates the variable c, which is hidden, looks like

var c = document.getElementById('pane').getContext('2d');

How can I save my code and use it outside of Code Monster?

Short answer: It's not super easy, but you can copy-and-paste your code and then load that code in an HTML file (either loading a separate Javascript file or inlining the Javascript in your HTML file).

Longer answer: A minimal HTML file that works would look like this:


		<html><body>
		

		<canvas id=pane width=400 height=300></canvas>
		

		<script>
		

		var c = document.getElementById('pane').getContext('2d');
		

		

		// PASTE YOUR CODE HERE
		

		

		</script></body></html>

If you copy that into a file, then copy-and-paste your code into it, then save the file with a filename ending in .html, you should be able to load the file in any web browser.

Is there any other code that is hidden from me?

There is also a bit of hidden code to try to stop animations when you change lessons and the code you write is instrumented to try to prevent infinite loops. You shouldn't need those to run your code outside of Code Monster.

Why aren't you telling me more about the syntax and terminology of Javascript?

There are already a lot of tutorials and textbooks out there that teach Javascript programming by explaining what a variable is, what variable scope is, what the syntax of an if statement looks like, how each of the operators work, and so on. If you want that, there are many choices available, many of which are excellent supplements to Code Monster.

What is hard to find is a tutorial that is fun, immersive, and gets you immediately building cool things. Code Monster skips a lot of the syntax and explanation you can get elsewhere (Google for it when you need it) and instead jumps straight into the fun of what you can do if you learn to code.

Why doesn't this work perfectly on an iPad (or other mobile device)?

Code Monster will load on many mobile devices, might even be a bit playable depending on your device, but it isn't designed for mobile. Why not?

Mostly because it is hard to type on mobile. Writing large amounts on a mobile device is difficult, and it is even worse when what you are trying to write is code and you need to keep looking at other parts of the code. Trying to write large amounts of traditional code on a mobile device is not a good experience.

In part because of that, no one seems to have created a great app yet for learning to code on mobile, but there are good apps out there that teach programming concepts (such as Hopscotch, Move the Turtle, and Cargo-bot).

Can I use Code Monster offline (when not connected to the internet)?

Sure! Code Monster only uses the internet at the very beginning, to load the website, and then never contacts the internet again.

So, for example, you can load Code Monster on a laptop, then go on an airplane or walk to a park where there is no internet connection, open your laptop there, and use Code Monster without the internet. It even still saves your place so you get back to the same lesson when you return! You don’t need an internet connection except at the very beginning when the website loads.
