What Will I Learn?
  • quickly test a game idea without writing a line of code
  • make a complete 3D game prototype using the Unity game engine and a 3D modelling app like Maya
  • learn about creating AI, game levels and how to run play tests
View Curriculum
  • You'll need the free Unity game engine installed on your machine
  • You'll also need a 3D modelling app. We recommend Maya LT, Silo or 3D Cheetah, but any 3D app will do, even Blender if you know what you're doing!
  • Knowing about the basics of Playmaker is a plus but not required. Check out Hutong Games' YouTube channel to get up and running quickly

Veteran game designer Christopher Orth takes you through every step of building your own first-person 3D game from scratch: from writing a game design document to whiteboxing a level the way AAA game companies do it and implementing game systems with basic AI - all without coding!

You'll be using the super-popular (and free!) Unity game engine together with the visual scripting tool Playmaker and the 3D modelling app of your choice to build an interactive first-person game level. Therefore, the people who'll get most out of it are those who already have some working knowledge of 3D modelling and have dabbled with Unity and Playmaker before a little and want to take their skills further. However, even absolute beginners can complete the course successfully.

You get:

  • More than 10 hours of high-quality lectures
  • 3 hours of bonus video content: whitebox reviews and time-lapsed speed-modelling of hours of game level development
  • free access to the student version of the awesome Playmaker Unity plugin
  • downloadable exercise files to follow along (utility textures, 3D models, ready-made health systems, etc)
  • Everything you need to make your very own 3D first-person game prototype!

Important note re Unity 5

The free student version of Playmaker is not currently compatible with Unity 5's new UI (user interface) system, so the Playmaker component (which is the majority of the class content) is done with Unity 4.3. We therefore recommend you use an earlier version of Unity to work with this course which you can get from the Unity Download archive, as it's possible to have more than one version of Unity installed on your computer.

The principles of what you're learning in terms of how Unity and Playmaker work are almost exactly the same between Unity 4 and 5 - it's just the mechanics that are slightly different with the new UI.

We plan on updating the course to Unity 5 as soon as Playmaker updates its plugin as well, so rest assured that if you're buying this course, we'll keep it updated for the future.

Who is the target audience?
  • This course is meant for beginners of all ages who preferably have already watched a few Unity tutorials and know the basics of getting around.
  • We have had students aged 10 all the way to people in their fifties take this course and have had rave reviews from our students
  • Die-hard programmers who don't like using visual scripting tools like Playmaker should probably look elsewhere

There is no right or wrong modelling app. While Christopher uses Maya and Silo here, there is absolutely no reason why you couldn't use Blender for example. However, neither of us are familiar enough with Blender to help you out, so just keep in mind that you may need to find help outside of this course should you choose to go down that path.

This is for non-commercial purposes only!

IMPORTANT: There's currently a bug in Unity 5 that prevents this action from working correctly!

Stay with Unity 4.6 if you can.

If you're on Unity 5+, you can try to use the custom action in this thread on the Playmaker forums:


Follow the instructions in this thread. The action needs to be added to the 'Actions' folder in your Unity project's 'Playmaker' folder. This only works for non-free licences! The limitation of the free version above is that it doesn not accept custom actions (like this one).

I have been teaching for over 12 years and set up indie game school in early 2014 to learn how to make games. I have enlisted the help of veterans of the game development industry to create fantastic courses around everything gamedev for anyone, using free or cheap tools.

Teaching has always been part of my life, because it’s so important to share what you learn. These days I mostly call myself a Game Designer, having worked on many high-profile titles launched on Playstation consoles, PC, and portable devices. But I’ve also worked as an Instructor, Team Leader, Technical Artist, Web Designer, Musician and Sound Designer. My own passion for learning has lead me to many avenues of contribution in this array of fun and fascinating fields.
