Implement a Dialogue Editor and Quest System and integrate it into an RPG project.

"I was worried it would be too centered round the RPG course and couldn’t stand alone and there wasn’t going to be enough detail for it to warrant being an extra course on its own. However I found it's a really good introduction to making custom editors almost irrelevant of quest etc. The original RPG isn’t essential, the skills maybe are but this almost stands alone. The course opens a big door to fancier work in the future and teaches concepts like dragging which are usable in game and in editor. It’s a great example of making the editor work for you not you working round the editor. Hurry and make more of the RPG series!"

- Liz Kimber, Early Access Reviewer

Using Unity 2020.1, we’ll show you how to include two essential game mechanics, dialogue and quests, in your games.

This highly acclaimed series was over 200% funded on Kickstarter, and is designed for intermediate users of Unity. We recommend you take at least the first half of our Complete Unity Developer 2D or 3D, or equivalent, as a prerequisite.

You can use the dialogue and quest systems together or independently in any game or project you build. We’ll be using an RPG as an example. You don't need to have completed the previous parts of the RPG Series (the RPG Core Combat and Inventory Systems courses) but it will give you an advantage if you already have.

The course is project-based as we believe this is the best way to learn Unity and C#. You will not just be learning dry programming concepts, but applying them immediately to a real RPG as you go.

We’ll provide the RPG project created so far in the series so that you can practice integrating to an existing complex project. Every element of the project we touch will be fully explained and no knowledge of the project will be required.

In the course we will be building the following from scratch:

  • A node based dialogue editor window
  • A ScriptableObject based dialogue asset
  • An in game dialogue UI
  • Dialogue triggers and condition to integrate with the gameplay
  • A quest list with multi-step objectives
  • Quest rewards given via the inventory system

In the process of the course we will cover advanced topics such as: IEnumerators, Saving Systems, C# Events, Interfaces and Unity UI.

You will get full lifetime access for a single one-off fee. The creators are qualified and experienced coders and avid gamers, so are able to explain complex concepts clearly, as well as entertain along the way.

You will have access to a course forum where you can discuss topics on a course-wide basis, or down to the individual video. Get plugged into our communities of amazing developers on Facebook (nearly 20k), in our own TA-curated Community (17k views/day), and our student chat group (10k live at any one time).

Dialogues and quests are core to many game genres. So why not join us and get started improving your game development right now?

Sam wrote his first game at 14, hacking together little games in Macromedia Flash during his summer holidays. Not long after, he taught himself C++ followed by Python and web programming. He was hooked.

In 2010 he went to study Computer Science at the University of Cambridge and he's been in Cambridge ever since. That is where he caught the entrepreneurial bug and realised he wouldn't want a traditional job for long. So after a few years working in various jobs to get experience, he quit and started burning through his savings looking for his calling.

At the end of 2015, he was coaching some friends to improve their programming skills. Realising how much he loved it, he started creating online courses and reached out to Ben for help. Fast forward and he's part of the GameDev.tv gang and gets to hang out with our awesome community!
