SMARTS
Simple Machine Artificial Reasoning Tree Structure
Do you want to know more? SMARTS is an implementation of behavior trees, a method for creating artificial intelligence for games first employed in HALO.
During the fall semester of 2009, three students from the Game and Engine Development course at Aalborg Univesity set out to find out new things about the game AI technique known as behavior trees. The framework here is the result of the first part of this work. It includes:
- SMARTS Designer
- The tool used to create behavior trees in a visual manner.
- SMARTS Library
- The core of the behavior tree system, and that which allows for calculations to be made on the behavior trees created using SMARTS Designer.
- SMARTS Test Bed
- A game based around the concepts originally developed by Namco for Pac-Man™, in which all opponents (and optionally the player's character) are controlled by behavior trees.
- Gluon plugins
- A preliminary implementation of a set of plugins for the Gluon game development system.

SMARTS source code (451KB)
This is the package containing the library, tool and test bed which was developed through so far four months of hard work. It contains the source code for the project, and is in fact a git clone of the repository on the 18th of December, 2009. Should you wish to download a binary version, there are two versions supplied below.
Requirements:
- Qt 4.5 or later
- Windows, MacOS X and Linux are tested platforms, but the software should run on any platform supported by Qt.
- If you wish to compile the Gluon plugins, libgluon is required
