AgentSpeak is an open-source Java-based implementation of the AgentSpeak(L) programming language, designed to facilitate the creation and management of BDI (Belief-Desire-Intention) autonomous agents. It features a runtime environment that parses AgentSpeak(L) code, maintains agents’ belief bases, triggers events, and selects and executes plans based on current beliefs and goals. The interpreter supports concurrent agent execution, dynamic plan updates, and customizable semantics. With a modular architecture, programmers can extend core components such as plan selection and belief revision. AgentSpeak enables developers in academia and industry to prototype, simulate, and deploy intelligent agents in simulations, IoT systems, and multi-agent scenarios.

APLib is designed to simplify the development of AI-driven autonomous agents within gaming and simulation environments. Utilizing a Belief-Desire-Intention (BDI) inspired architecture, it offers modular components for perception, decision-making, and action execution. Developers define agent beliefs, goals, and behaviors via intuitive APIs and behavior trees. APLib agents can interpret game state through customizable sensors, formulate plans using built-in planners, and interact with the environment via actuators. The library supports integration with Unity, Unreal, and pure Java environments, facilitating automated testing, AI research, and simulations. It promotes reuse of behavior modules, rapid prototyping, and robust QA workflows by automating repetitive test scenarios and simulating complex player behaviors without manual intervention.
