The research integrates RL into the NPC behaviourto allow for the more realistic, dynamic interactions and responsive behaviourthat today's gaming environments require. We will review state-of-the-art RL algorithms and validate improvements implemented in our own RL model within a sandbox game environment into NPC decision-making and player engagement. According to our results, RL makes NPCs adaptive, tactically deep, and realistic while the classical ones fail. The study provides rigorous methodology and analysis to demonstrate the feasibility and advantages of using RL for the design of a new generation of games. Keywords:NPC,Video Game, RL Algorithms, Game Environment.
