Development of a video game using multi-agent modelling

Abstract

The last decade has seen Artificial Intelligence (AI) seep into the game development industry, Artificial intelligence is used in video games to create believable characters that challenge the player and enrich the playing experience. The adventure genre is one of the types of games where it is fundamental to have non-player characters with the ability to perceive the environment, detect some of the player character’s actions and react to them with astute strategies. The goal of this project was to develop a game with enemy characters that would cooperate to defeat the player. In the final game, the enemies patrol the game’s world trying to locate the player character. The findings of an enemy are immediately communicated to the rest of agents, and the player character is chased and attacked by the enemies after being spotted. Agents pursue the player character and use close combat moves. The 3d game objects was developed with the Blender software, The game was developed with the Unreal Engine 4 game engine. The reasoning and decision making of enemies was modelled using behaviour trees. The implemented system makes agents capable of perceiving visual and auditory stimuli and communicating information to other agents, who compare it with their own knowledge to take independent decisions. The whole set of enemies form an artificial intelligence-based multi-agent system and cooperate to achieve the shared goal of defeating the player in the shortest time possible. The ability of the numerous enemies to spot the player character and detect sounds of players.Unlike them, player try struggle to out of the perception system, and Avoid contact with them.
