Java Action Interpolate is a specialized Java library designed to integrate with the LightJason multi-agent framework. It provides a suite of interpolation algorithms, including linear, polynomial, and spline methods, enabling agents to transition between states and actions fluidly. The module offers configurable interpolation parameters, hooks into the LightJason action lifecycle, and supports custom data types. By incorporating Java Action Interpolate, developers can eliminate jarring behavior jumps, enhance simulation fidelity, and simplify the implementation of smooth agent movements and decision-driven behaviors within distributed or simulation environments.
