starting steps for beginners

1st - Download DizzyAGE

Download the latest development tools and the documentation books,
from the DizzyAGE website.
You'll need the file and the three books, in chm format.

Now, if you feel like starting with a detailed tutorial, I'd recommend Jamie's "Make Your Own Dizzy Games" which you can get from the techincal articles section. If you're more into video tutorials, Jamie has a few of those too, on the videos page. Or you could start slow, by going through the whole documentation, books and so.

2nd - Read the books

Start with The GS9 Book.
This is a programming manual that presents the GS9 scripting language, used in all DizzyAGE games. Don't worry, no prior programming knowledge is required, and this book will take you from the very beginning. The book also provides a small console application, for testing the presented examples. If you never programmed before, take it easy and don't be too hard on yourself. You can always return to this book when you need it. If you already have experience with programming languages, especially C/C++, you will get through pretty quick.

Move to The Editor Book.
It presents the map editor and it teaches you how to use it to create the game map. This book also introduces you to some basic notions of DizzyAGE games, like tiles, brushes and properties.

Finally, read the The DizzyAGE Book.
This book requires you to have read the other too and gained both scripting and map editing knowledge. It's a practical guide that presents the components of DizzyAGE games and teaches you how to implement the most common puzzles, found in Dizzy games. The chm version also provides index search for functions and commands used in games.

If for some reason, you can't open the chm books, the documenation can also be read online.
The html versions use java script, so make sure you have it enabled in your web browser.

3rd - Check the demo game

Download and check the small demo game, Dizzy and the Mushroom Pie. Compare it's scripts to the default template and find out how various puzzles have been implemented. It's nothing too fancy, but you'll see how a few simple techniques are used together, in a small and funny game. Later you can unpack other people's games too and see how they implemented their puzzles.

4rd - Articles, forums and help

Whenever you need help, don't hesitate to ask for it!
There is a series of How To? articles. They provide answers to a lot qestions and I hope to extend them in the future. For advanced users, there are a few technical demos, presenting implementations of tricky features. You can ask for help or advice on the DizzyAGE support page, or in the community forums.

5th - Your own game

It's time to start working on your own game!
Go for something small at first and make sure you manage to finish it.
When ready, test it well and submit it to the DizzyAGE website, to be listed on the games page.
Other Dizzy fans will be happy to play it, and fans always provide good feedback, that could improve your games in the future.

Good luck!
