Three-dimensional games are an indispensable tool in education and cultural transmission, offering users immersive experiences that facilitate learning through engagement and direct experience. The aim of this study was to design and implement an advanced cutscene sequencer in Unity 3D, targeted at educational and cultural games, to assist game developers in producing cinematic interludes, which are a key narrative element in games. The project methodology encompassed a detailed process of planning, design, and implementation. This involved the comprehensive use of various tools, including Unity 3D for game development, C# for scripting, Visual Studio for integrated development, Git for version control, Blender for 3D modeling, Substance Painter for texturing, and Audacity for audio editing. These tools collectively facilitated the development of a robust cutscene sequencer system designed to create engaging and dynamic narrative scenes. The project’s results indicate that the use of an advanced sequencer can significantly impact the efficiency and creativity of the game and educational material creation process, offering developers the opportunity to explore practically unlimited viewing perspectives. This tool enables the creation of rich and diverse visual experiences, which is crucial for engaging and educating players.
