Tools for working with [Unity's
NavMeshComponents](https://github.com/Unity-Technologies/NavMeshComponents) and
generating navmesh: link generation, mesh cleanup, etc
Default NavMesh Generation | Using NavLinkGenerator's Bake Links and Interior Volumes
:-------------------------: | :-------------------------:
 | 
 | 
## NavLinkGenerator
NavLinkGenerator is an asset for generating
[NavMeshLinks](https://docs.unity3d.com/Manual/class-NavMeshLink.html) across
gaps in your navmesh. It also serves as the central hub for navgen.
NavLinkGenerator is a ScriptableObject -- so you need to create one to start
using it (Assets > Create > Navigation > NavLinkGenerator). The asset contains
settings and buttons for generating links.
# NavNonWalkableCollection
The "Create Interior Volumes" button in NavLinkGenerator creates a
NavNonWalkableCollection which tracks the volumes so they can be rebuilt.
Remove a volume from this component's list to prevent it from being modified.
# NavMeshAreas
You can assign enum values from `UnityEngine.AI.NavMeshAreas` to NavMeshAgent's
AreaMask and `UnityEngine.AI.NavMeshAreaIndex` to area indexes in
NavMeshSurface, NavMeshLink, NavMeshModifierVolume, etc. These enums are
automatically updated from the areas defined in Navigation (Window > AI >
Navigation).
[NavMeshAreas generates two enums
](https://github.com/idbrii/unity-navgen/blob/16d4ba6c16228d7f7b9fe7a91ff8b8a837ba842c/Runtime/NavMeshAreas/NavMeshAreas.cs#L19-L32)
that look something like this:
```cs
// NavMeshAgent uses AreaMask.
[Flags]
public enum NavMeshAreas
{
None = 0,
Walkable = 1, NotWalkable = 2, Jump = 4, Climb = 8, Blocked = 16, Hole = 32, Edge = 64, Fall = 128, New1 = 256, Stuff = 512,
All = ~0,
}
// NavMeshSurface, NavMeshLink, NavMeshModifierVolume, etc. use indexes.
public enum NavMeshAreaIndex
{
Walkable = 0, NotWalkable = 1, Jump = 2, Climb = 3, Blocked = 4, Hole = 5, Edge = 6, Fall = 7, New1 = 8, Stuff = 9,
}
```
# Example
See the [example branch](https://github.com/idbrii/unity-navgen/tree/example) for a demonstration project.
# Installation
1. Install Unity [NavMeshComponents](https://github.com/Unity-Technologies/NavMeshComponents.git) from github.
2. Copy the code to your project or add a dependency to your manifest.json to install as a package:
"com.github.idbrii.unity-navgen": "https://github.com/idbrii/unity-navgen.git#latest-release",
# Alternatives
