Third gen. behavior trees, only for C# programmers.

Active Logic redefines game AI, real time and turn based control.

Where other BT libraries reinvent wheels at every turn, AL gives you... C#.

Not one library integrates as tightly with our favorite OOP language, and as a result AL produces logic that's incredibly concise, readable and accurate.

Say goodbye to lambdas, co-routines, 'conditional nodes' and other nonsense:

- Robust, type safe support for inline sequences and selectors via conditional operators and more.
- Full support for BT style decorators: need a cool-down or timer? One function call, no explicit "book-keeping".

Active logic is perhaps the most comprehensive BT library out there. Where other libraries force a choice between stateful and stateless control, AL does both; and if you need mutable trees, that is also supported.

Comprehensive Unity integration includes a visual debugger with logging, soft breakpoints and visual history.

Designed for high performance:

- 'status' is a tiny struct that lives on the stack
- Low/no GC (stateless core)
- Optimized builds (strip logging calls)

Fully documented, unit tested and fitted with an example showing effective uses in game AIs, user input and game managers.
