Godot Games Engine

I recently looked back to some of the old projects I worked on using Flash back in 1999 to 2003 or so. Some of those projects involved games development and generative art. I enjoyed programming in ActionScript 2 and 3 - and I enjoyed the creativity and freedom that Flash gave me for creating fun things.

I wanted to find something similar to Flash for creating some games and interactive experiences. Ideally it would be cross platform - and I stumbled across Godot Engine . As it's Open Source (MIT Licence - so actually Free Software) - a huge plus!

The UI for Godot is great, and the scripting language (GDScript) seems neat - it's python like. If you don't like that you can use C# and you can also extend it with other languages such as C++ and Go.

As a programmer, I wanted to first checkout the scripting language - and see what it was like. So, as I often do, I decided to write a simple 2d Cellular automata (See code below). From opening up the Editor for the first time, doing a spot of reading about how to set up a Scene and use it's Node system, it took me about 30 minutes to write a simple 2d Cellular automata. The built in IDE is great, with code highlighting, code suggestions and also a comprehensive debugging tool.

Agreed. Godot is pretty cool.
