Abstract : This paper discusses the development of the city generation system known as the City Generator Unity, which generates real-time city environments within the Unity game engine using graph-based algorithms and seed-based city generation techniques. This paper outlines the system architecture and implementation of the system within gaming and virtual simulation environments. Performance measures indicate the effective creation of cities with expansive road infrastructure and multiple construction sites within real-time frames. Parameters such as seed values are also made accessible within the system, which are necessary for the customization of the system’s modular design, creating a consistent yet varied natural environment within the cityscapes of each city. This work contributes to the development of procedural content generation techniques by creating city layouts within the game engine [1][2].
