Player Boundary System

Player Boundary System is a lightweight and modular Unity toolkit that allows you to restrict player movement inside configurable gameplay areas without relying on colliders, invisible walls or complex navigation systems. Create circular or rectangular movement boundaries and combine them using powerful composite operations to build sophisticated playable spaces with minimal setup. Composite Operations include Union to combine multiple playable areas into a single movement space, Subtraction to exclude forbidden zones from existing playable areas, and Intersection to restrict movement to overlapping boundary regions. The entire system works at runtime and fully supports transform position, rotation and scale. Perfect for arena-based games, puzzle and exploration games, open world gameplay restrictions, safe zones and forbidden areas, prototype environments, CharacterController-based projects, lightweight gameplay systems, WebGL builds, and stylized game development. Core features include circular and rectangular movement boundaries, composite boundary operations, lightweight runtime movement restriction, compatibility with CharacterController, Rigidbody and transform-based movement, runtime boundary visualization, scene Gizmo visualization, optional fall detection with Unity Events, custom inspectors for fast setup, full support for rotated and scaled transforms, and modular extensible architecture.
