# Active Logic

[![Build Status](https://travis-ci.com/active-logic/activelogic-cs.svg?branch=master)](https://travis-ci.com/active-logic/activelogic-cs)

[![codecov](https://codecov.io/gh/active-logic/activelogic-cs/branch/master/graph/badge.svg)](https://codecov.io/gh/active-logic/activelogic-cs)

Easy to use, comprehensive Behavior Tree (BT) library built from the ground up for C# programmers:

- Game logic, game AI (autonomous agents)

- Asynchronous control applications

- No DSL/builder pattern (tight integration)

- Use standalone or borrow the "ticker" from a visual BT solution

=> [Quick-start guide](Doc/QuickStart.md) || [Unity quick-start guide](Doc/QuickStart-Unity.md) || [API reference](Doc/Reference/Overview.md) || [FAQ](Doc/FAQ.md)

## Introduction

Active Logic seamlessly integrates with C#:

```cs

class Duelist : UTask{

    float     health = 100;

    Transform threat;

    // BT selectors and sequences via || and &&

    override public status Step()

        => Attack()

        || Defend()

        || Retreat();

    // Conditionals without 'conditional nodes'

    status Attack() => (threat && health > 25) ?

        Engage(threat) && Cooldown(1.0f)?[ Strike(threat) ]

      : fail(log && $"No threat, or low hp ({health})");

    status Defend() => ...;

    // ...

}

```

Active logic is the first BT library providing tight integration with the host language

(no DSL, no builder pattern, no lambdas or coroutines, no blackboard).

This means better performance (low/no GC), cleaner syntax and the freedom to structure your code as you wish.
