# NavMeshPlus
|
|
|
|
NavMesh building components provide you with ability to create navigation meshes that are generated automatically from your Scene
|
|
geometry, which allows characters to move intelligently around the game world.

# Unity 2D Pathfinding
|
|
|
|
This repo is a proof of concept of Unity NavMesh and Pathfinding in 2D. It is explores NavMeshComponents capabilities. [[link]](https://docs.unity3d.com/Manual/class-NavMeshSurface.html)
|
|
|
|
## Wiki [[here]](https://github.com/h8man/NavMeshPlus/wiki)
|
|
|
|
See [how-to](https://github.com/h8man/NavMeshPlus/wiki/HOW-TO) for full tutorial
|
|
|
|
## Setup
|
|
|
|
You can use this in two different ways: downloading this repository or adding it to your project's Package Manager manifest.
|
|
Alternatively, you can pick scripts and place in your project's `Assets` folder.
|
|
|
|
### Variant 1. Download
|
|
Download or clone this repository into your project in the folder `Packages/com.h8man.2d.navmeshplus`.
|
|
|
|
### Variant 2. Package Manager Manifest
|
|
[Git](https://git-scm.com/) must be installed and added to your path.
|
|
|
|
The following line needs to be added to your `Packages/manifest.json` file in your Unity Project under the `dependencies` section:
|
|
|
|
```
|
|
"com.h8man.2d.navmeshplus": "https://github.com/h8man/NavMeshPlus.git#master"
|
|
```
|
|

## 2D NavMesh
|
|
|
|
In repo you will find implementation of NavMeshSurface2d for tilemap top down games.
|
|
|
|
To use it in your project:
|
|
|
|
1. Copy repo into your Asset folder
|
|
2. Create Empty Object in scene root and rotated respectively to Tilemap (x-90;y0;z0)
|
|
3. Add NavMeshSurface2d component to Empty Object
|
|
4. Add Tilemap with NavMeshModifier component, override the area.
|
|
5. In NavMeshSurface2d hit Bake.
|
|
|
|
How does it works:
|
|
|
|
1. It uses https://docs.unity3d.com/Manual/class-NavMeshSurface.html as base implementation.
|
|
2. Implements world bound calculation.
|
|
3. Implements source collector of tiles, sprites and 2d colliders
|
|
4. Creates walkable mesh box from world bounds.
|
|
5. Convert tiles, sprites and 2d colliders to sources as NavMeshBuilder would do.
