In　games,　players　are　not　always　interested　in　giving　non-player　characters　of　human-level　intellect.　Usually,　game　producers　write　codes　to　control　non-human　creatures　such　as　dragons,　robots,　or　even　rodents.　Artificial　Intelligence　(AI)　in　game　programming　needs　further　study　to　solve　fairly　complex　problems.　However,　if　a　Non-People　Character　(NPC)　is　used　for　attempting　to　have　different　personalities　and　unusual　appearances　with　emotions,　fear,　and　disposition,　the　effect　of　entertainment　and　the　variety　of　game　content　is　expected　to　be　much　stronger.　At　present,　the　artificial　intelligence　interest　level　in　the　game　industry　is　relatively　low　owing　to　restrictions　of　existing　level,　hardware　resources.　But　recently,　game　developers,　producers　and　managers　reckon　artificial　intelligence　application　as　one　of　the　important　factors　for　game　programming.　This　study　analyses　the　behavioral　course　of　NPC　applied　genetic　Artificial　Intelligence　Method　to　maintain　the　players’　interest　and　provide　the　way　to　enhance　their　interest.　It　demonstrates　designed　and　realized　game　NPC　behavioral　course　is　used　properly　in　the　game　map.　©　2015　Taylor　&　Francis　Group,　London.
