Intelligent controlling method of non player characters

Abstract

The invention provides an intelligent controlling method of non player characters (NPC). The method comprises the following steps: after the NPC receives a network packet, position, speed and angle of all NPCs at next moment can be predicted by utilizing a Kalman filtering-based dead reckoning method; predicting actions selected by each NPC according to the prediction result and the last position, speed and angle of each NPC; and broadcasting update information to collaborative NPCs only when the predicted information is not accurate so that each collaborative NPC updates state information. Therefore, by reducing the broadcasting frequency of update information, the pressure of a server during the operation of massively multiplayer online game (MMOG) can be reduced, and transmission delay in the MMOG communication and influence of information packet loss on the NPC collaboration effect can be reduced.

Description

technical field [0001] The invention relates to an intelligent learning technology, in particular to an intelligent control method for a non-player-controlled character (NPC) in a massively multiplayer online game (MMOG). Background technique [0002] With the intelligent development of online games, most online games use artificial intelligence technology. As the core of the game, artificial intelligence can provide more and more realistic game challenges and stimulate players' interest. In addition, artificial intelligence often plays a decisive factor in game playability. Applying artificial intelligence to games will make players feel that the behavior of characters in the game is convincing and reasonable, thereby attracting players and effectively promoting the game. The success of game development. [0003] At present, a heuristic accelerated evaluation Q-learning method (HAE-QL method for short) is proposed, which can be used to make intelligent decisions about the...

AI Technical Summary

Problems solved by technology

[0013] In practical applications, the transmission delay and packet loss problems in MMOG communication are unavoidable, making it sometimes difficult for NPCs to obtain the status information of cooperative NPCs in real time, resulting in the NPC's choice of actions not reflecting the collaboration between NPCs. Sex, that is, it is impossible to obtain better NPC cooperation effects

In addition, in the above-mentioned HAE-QL method, every time each NPC performs an action, it must broadcast state information to its cooperative NPC, so that the historical experience information used by each cooperative NPC to make action decisions is consistent, so as to obtain a better cooperation effect. , in this way, the server needs to process a large amount of data transmission at the same time, obviously this will bring huge computing pressure to the server, resulting in a significant decrease in the performance of the server
