Research On NPC Mapping Library Design Based On Player Preference

With the development of Internet technology,the game industry has been at its peak in recent years.In 2019,the revenue of the domestic game industry reached233.03 billion yuan,an increase of 8.7% over the same period in 2018.As the core of the game,game characters can be divided into Player-Controlled characters(PCC)and Non-player-Controlled characters(NPC).Players can customize many controllable characters by themselves in many games.However,for some players,they lack patience while trying to be personalized,and the high degree of customization also leads to the problem of data flooding.there is not much attention or research on NPC that play an important role in the game.If we can build personalized NPC according to the character and preference of players,so that players can have empathy and intimacy in the game,it is of great significance to improve the game's playability and protect the loss rate of players.The research of this paper consists of four steps.The first step is based on two theories.Keirsey's personality temperament theory establishes personality correlation between players and NPC and Csikszentmihalyi's flow theory guides the practice of model.The second step will analyze some NPC cases at home and abroad to carry out multi-dimensional division.Then,according to the results of the analysis,a questionnaire will be designed to collect the preferences of players of different temperaments,which will become a "gene molecule".Finally,the concept of "NPC mapping library" is put forward,and the conceptual model will be built according to the research results.It is concluded that "NPC mapping library" consists of three levels.Preparation level--classification of style and appearance,which is divided into cartoon and realistic style.Cartoon is the abstraction of the virtual world,while realism is the restoration of the real world.The appearance is summarized as humanoid and anthropomorphic,and will be further subdivided.Decision layer--the character determines the appearance.The players of four temperament types are investigated to obtain their different preferences in terms of character appearances,color systems and style elements.Different appearances will correspond to different characters according to their preferences.Auxiliary layer--language expression and action,which will systematically establish a relationship between language,expression,action and NPC personality.Finally,"NPC mapping library" is applied to the game scene from the application level.It is transformed into a module in the game so as to increase the players' experience in the way of rewarding mechanism and competition mechanism,which will provide ideas for NPC mapping library's transformation from concept to practice.
