Method for learning non-player character combat strategies on basis of deep Q-learning networks

Abstract

The invention discloses a method for learning non-player character combat strategies on the basis of deep Q-learning networks. The method for learning the non-player character combat strategies on thebasis of the deep Q-learning networks has the advantages that the locations, skill cooling time and control states of learning non-player characters and locations, skill cooling time and control states of sparring characters are used as input states, all skills of the learning non-player characters are used as output action sets, the deep Q-learning networks are used as learning algorithms, bloodvolume difference information of the characters of two parties is used as reward for the deep Q-learning networks, the minimum time difference errors are used as targets, back propagation computationis carried out, and hidden layer weight coefficients and output layer weight coefficients of deep neural networks can be updated; the non-player character combat strategies can be automatically generated by the aid of the method, accordingly, the efficiency and the flexibility can be improved, the battle capacity can be reinforced, and the challenging and the interestingness of games can be obviously enhanced.

Description

technical field [0001] The invention relates to a method for learning game combat strategies, which belongs to the field of machine learning, and in particular to a method for learning combat strategies of non-player characters based on a deep Q-learning network. Background technique [0002] The combat strategy of non-player characters (Non-player character, NPC) in the game is a very important part of the game experience, especially in fighting games. The quality of the combat strategy directly affects the overall evaluation and sales of the entire game. A good combat strategy includes reasonable positioning, instant response to key skills, knowing how to use some skills to restrain enemy units, etc. [0003] For the combat strategies of non-player characters in the game, the behavior tree is used to write fixed responses to each state. The problems with this method are: first, it is difficult to guarantee the pros and cons of the response actions, which can only be done ...

AI Technical Summary

Problems solved by technology

[0003] For the combat strategies of non-player characters in the game, the behavior tree is used to write fixed responses to each state. The problems with this method are: first, it is difficult to guarantee the pros and cons of the response actions, which can only be done artificially. Judging its pros and cons; secondly, the efficiency is low, and it takes a lot of time and energy to design these responses; finally, the flexibility is poor, and it cannot respond differently to the playe
