SkookumScript's origin story

By Conan Reis, SkookumScript creator and Agog Labs CEO

I first used a game-centric scripting language at Electronic Arts Canada in the early 1990s, when it was still small enough to know most people by name. Although that language, Xyzzy (pronounced “cheezy”), was fairly primitive, using it was a great experience and I quickly realized that scripting languages are the best way to create gameplay logic and make the game development process more satisfying and fun.

When I started developing my own video game projects, I found no programming language available that truly met many key needs of game development. Yes, you can make a game without a dedicated language – but any self-respecting craftsman knows you should use the right tools for the job. Making fantastically great games is my goal, so rather than use something sub-optimal, I embarked on a decades-long journey that would culminate in the creation of SkookumScript.

Ergo

I started work on my first game scripting language, Ergo, in 1995. Ergo was funded in part through a $105K grant from the BC Science Council (now known as the BC Innovation Council). It was a powerful and compact distributed programming language with a syntax that fit on a single page. It enabled you to write one program and have it run on several networked computers. When it required greater processing power, it would add additional computers to distribute the load and get faster results. This was over a decade before the term cloud computing was popularized around 2006.

I have been building and evolving game scripting languages ever since. SkookumScript has some concepts from Ergo in its DNA – particularly closures and the ability to transfer hunks of code across networks.

ChewieScript

In 2001 I started a multi-year stint at LucasArts Entertainment, who hired me to create the successor to the venerable SCUMM scripting language. Initially called “Son of SCUMM”, my new language ChewieScript (named after the iconic Star Wars engineer Chewbacca) was designed for practicality, performance and scalability.

Observing ChewieScript being used to develop Star Wars: Bounty Hunter taught me a great deal about what works and what leads to bugs, especially in a team setting. Several features I thought were great in theory turned out not to be, well, not-so-great in practise. So, based on the team’s feedback, I refined those features until they really were great – which is to say, conducive to both great gameplay for the player and optimal workflow for the development team.

This firmly instilled the ethos of “eating your own dog food” in my development of tools and tech – which is why reusability has long been one of my major priorities. Over the years I have worked at various video game companies, I licensed my language tech and accompanying application program interfaces (APIs) to each company, allowing me to keep ownership of (and build on) the tech rather than abandon it at the end of each game project. As a result, some of ChewieScript’s DNA lives on in SkookumScript today.

SkookumScript

Work on SkookumScript officially began in July 2004. SkookumScript is “right” and “real”, in that it evolved and continues to be enhanced during the development of actual shipping games for over a decade. I never cluttered things up by adding unnecessary features—we were shipping a game and did not have time to be “Architecture Astronauts”. However, SkookumScript does have the bits that were not initially planned for but ended up being needed at the eleventh hour—because in the end we did ship.

It is my firm belief that all successful languages are grown and not merely designed from first principles.

Gameplay tools are often developed while they are in active use developing a game title, but just when they are getting really good and useful, the game ships and the tools are discarded, and then rebuilt from scratch for the next title. SkookumScript was designed to render this wasteful practice obsolete.

Being present at all phases of a project has enabled SkookumScript to painlessly scale to a project’s size. It works well both in the starting phases of a project with few people and many unknowns, and during finaling when there are many people who require stability, performance and predictability. SkookumScript has had the time to evolve and become lean, efficient, practible, scalable, maintainable, and reliable—the good parts have been made great, while any painful bits have been pruned out.

Agog Labs Inc. was incorporated in October 2013 by wrapping a company around SkookumScript and the goal to get it in the hands of the entire game development industry and beyond.

Good software takes ten years.

SkookumScript will save you time, money and brain cells, and help you make your great games even greater. It is my gameplay tool of choice (big surprise there!), and many others who have used it think so too.

SkookumScript is, in a word, skookum. Which is Canadian for “awesome”.
