Research Supports Voice Commands Non-Player Character Intelligent Decision Making Model

The past two decades, with the rapid development of computer hardware and software levels, electronic games technology also has been greatly enhanced. The game’s AI begin and graphics, sound, human-computer interaction as game design has become a particularly important part, In the third-person shooter (Third-Person Shooter, TPS), if the non-intelligent human players (Non-Player Character, NPC) can access information in the game environment, sense changes in the surrounding environment, and make a reasonable decision-making behavior and responses, and the players collaboration or confrontation, can greatly enhance the player’s gaming experience.In the traditional third-person shooter TPS, often there will be more non-human players NPC exists inside the game scene, but between the NPC often acted alone and without cooperation among agents, which is not realistic Happening. Further, in the conventional TPS game, between the players and the NPC Player nor an explicit exchange and cooperation; Players Player in general just a participant, not the commander, it can not be an explicit way command of one’s own NPC actions, so as to achieve more effective cooperation.To solve these problems, this paper TPS game in the multi-agent decision model a study, carried out the following two things:(1) based on the "behavior tree" method, to study the behavior of the decision-making model TPS-game multi-agent, to achieve between the NPC, and the NPC decision and concerted practices between players. (2) Construction of a voice-based control behavior of the game, players can publish voice commands to achieve the game’s NPC team and player avatars controlled. This control can better support collaboration with the NPC in the game and the players; players also can reflect its role as the commander; on the other hand, for the mobile platform game, it is difficult through the mouse and keyboard to enter a large amount of control information, and this voice control will have certain advantages.This work is a game between multi-agent collaborative decision-making and behavior between man and NPC interaction and improvement of thinking, intelligent decision support voice commands models constructed for TPS game, especially in the mobile phone game artificial intelligence and TPS interaction design has a certain reference value. Through the game, experiment and application testing to verify the effectiveness of voice commands to control intelligent decision model. Test results show that the decision-making model, NPC in the game can take reasonable intelligent behavior; while players Player release voice command can be accurately interpreted and executed. Overall AI is stable, speed is good.
