RecastNavigation for Unity

Unity Engine Plugin for RecastNavigation

This project is a modified version of RecastNavigation. It maintains all the original functionality while adding a plugin that allows direct NavMesh generation within the Unity engine.

• Original: https://github.com/recastnavigation/recastnavigation
• License: Follows the original author's ZLib license.

• Developed a native plugin that enables direct NavMesh generation within the Unity engine
• Unity script integration through C# wrapper classes
• NavMesh generation and visualization tools for Unity editor

This project was developed for use in the following architecture:

• Client: Built with Unity engine
• Server: C++ based server
• Pathfinding: NavMesh-based pathfinding calculations performed on the server

Clients and servers can share the same NavMesh data to ensure consistent pathfinding results.
