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

• Union – Combine multiple playable areas into a single movement space.
• Subtraction – Exclude forbidden zones from existing playable areas.
• Intersection – Restrict movement to overlapping boundary regions.

The entire system works at runtime and fully supports transform position, rotation and scale, making it easy to integrate into both existing and new projects.

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
• Stylized game development

Designed for Developers

Player Boundary System was designed to be simple, efficient and easy to integrate into existing Unity projects.

Instead of relying on physics constraints or navigation systems, it provides a lightweight runtime solution focused exclusively on restricting player movement inside configurable gameplay areas.

Whether you're building prototypes, indie games, stylized experiences or WebGL projects, Player Boundary System lets you create and combine movement boundaries quickly while keeping your project clean, modular and performant.
