NavMesh Eraser
Features of NavMesh Eraser
NavMesh Eraseris designed to simplify the process of selectively removing or excluding specific areas from Unity’s NavMesh directly within the Scene View. This tool offers granular control over navigation zones, enhancing the ability to create complex and tailored navigation environments. Below are the main features of the tool:
Intuitive Area Exclusion with Brush Tool NavMesh Eraser allows users to exclude specific areas from the NavMesh using a straightforward brush interface. Users can control brush size, preview the area in real-time, and toggle “Paint Mode” on and off to mark areas as non-walkable. The tool also includes an “Erase Mode” that removes exclusion zones, allowing users to quickly edit the NavMesh without affecting other elements in the scene.
Configurable NavMesh Modifier Volumes Each excluded area is represented by a NavMesh Modifier Volume, which provides essential customization options. Users can adjust the volume’s size and center, set the area type to “Not Walkable,” and specify which agents are impacted by the exclusion. This configuration ensures each excluded area serves the exact needs of the navigation setup, enabling complex, multi-agent navigation control.
Organized Scene Management and Undo Support Excluded areas are automatically organized under a parent GameObject in the hierarchy, streamlining scene management. Furthermore, all exclusion and removal actions are registered with Unity’s undo system, allowing users to easily revert changes if needed. This functionality ensures a clean and editable scene without unnecessary clutter.
Why and How NavMesh Eraser Was Created
NavMesh Eraser was developed to give Unity developers an efficient and precise tool for managing non-walkable areas in navigation setups. Traditional methods for excluding zones from a NavMesh can be rigid and time-intensive, requiring multiple adjustments to geometry or baking parameters. NavMesh Eraser introduces a visual, real-time solution, enabling developers to paint non-walkable areas directly within the Scene View.
The design of NavMesh Eraser emphasizes flexibility, accuracy, and real-time visual feedback:
Real-Time Scene View Interaction: By integrating with Unity’s Scene View and providing a brush tool, NavMesh Eraser allows developers to visually mark areas as non-walkable. This interaction ensures precision and helps prevent navigation inconsistencies in real time.
Enhanced Control with Modifier Volumes: Each excluded area is fully configurable, offering control over which agents are affected and the specific properties of each exclusion zone. This modular approach makes NavMesh Eraser adaptable for diverse project needs, including multi-agent setups and complex navigation paths.
In summary, NavMesh Eraser provides a streamlined workflow for creating nuanced navigation setups in Unity. By reducing the time and effort needed to configure non-walkable areas, it enables developers to focus on designing responsive, engaging environments without repeated adjustments.
