JasonEnvironments delivers a collection of environment modules designed specifically for the Jason multi-agent system. Each module exposes a standardized interface so agents can perceive, act, and interact within diverse scenarios like pursuit-evasion, resource foraging, and cooperative tasks. The library is easy to integrate into existing Jason projects: just include the JAR, configure the desired environment in your agent architecture file, and launch the simulation. Developers can also extend or customize parameters and rules to tailor the environment to their research or educational needs.
