NavmeshAdd Class Reference

Adds new geometry to a recast graph. More...

Detailed Description

Adds new geometry to a recast graph.

This component will add new geometry to a recast graph similar to how a NavmeshCut component removes it.

There are quite a few limitations to this component though. This navmesh geometry will not be connected to the rest of the navmesh in the same tile unless very exactly positioned so that the triangles line up exactly. It will be connected to neighbouring tiles if positioned so that it lines up with the tile border.

This component has a few very specific use-cases. For example if you have a tiled recast graph this component could be used to add bridges in that world. You would create a NavmeshCut object cutting out a hole for the bridge. then add a NavmeshAdd object which fills that space. Make sure NavmeshCut.CutsAddedGeom is disabled on the NavmeshCut, otherwise it will cut away the NavmeshAdd object. Then you can add links between the added geometry and the rest of the world, preferably using NodeLink3.

Mesh mesh

Custom mesh to use.

The contour(s) of the mesh will be extracted. If you get the "max perturbations" error when cutting with this, check the normals on the mesh. They should all point in the same direction. Try flipping them if that does not help.

float meshScale = 1
Vector2 rectangleSize = new Vector2(1, 1)

Size of the rectangle.

Transform tr

cached transform component

int [] tris

Cached triangles.

MeshType type
bool useRotation

Includes rotation in calculations.

This is slower since a lot more matrix multiplications are needed but gives more flexibility.

Vector3 [] verts

Cached vertices.
