In　this　paper,　we　present　a　method　based　on　large　language　models　for　murder　mystery　game　scriptwriting,　which　not　only　helps　ordinary　user＇s　one-click　generation　of　ideas　into　a　complete　work,　but　also　helps　professional　scriptwriters　to　improve　the　efficiency　of　creation.　The　main　idea　of　this　paper　is　to　develop　prompt　engineering　to　communicate　with　the　large　language　model,　so　that　the　model　can　accurately　generate　the　required　content　according　to　the　user＇s　thread,　and　improve　the　quality　of　the　output　scripts.　Through　the　effective　combination　of　AI　and　human　thinkings,　the　paper　explores　the　potential　application　prospects　of　AI　in　murder　mystery　game　script　generation　and　expression　with　a　new　perspective　and　means.　©　2024　IEEE.
