Class TileHandler

Public

Utility class for updating tiles of navmesh/recast graphs.

Primarily used by the TileHandlerHelper for navmesh cutting.

Most operations that this class does are asynchronous. They will be added as work items to the AstarPath class and executed when the pathfinding threads have finished calculating their current paths.

CutAll= 1	Cut holes in the navmesh.
CutDual= 2	Cut the navmesh but do not remove the interior of the cuts.
CutExtra= 4	Also cut using the extra shape that was provided.

Int3[]	clipIn	Input vertices
Int3[]	clipOut	Output vertices. This buffer must be large enough to contain all output vertices.
Int2	size	The clipping rectangle has one corner at the origin and one at this position in XZ space.

Int3[]	verts	Vertices that are going to be cut. Should be in graph space.
int []	tris	Triangles describing a mesh using the vertices.
Int3[]	extraShape	If supplied the resulting mesh will be the intersection of the input mesh and this mesh.
GraphTransform	graphTransform	Transform mapping graph space to world space.
IntRect	tiles	Tiles in the recast graph which the mesh covers.
CutMode	mode=CutMode.CutAll\|CutMode.CutDual
int	perturbate=-1	Move navmesh cuts around randomly a bit, the larger the value the more they are moved around. Used to prevent edge cases that can cause the clipping to fail.

TileType	tile	Tile type to load
int	x	Tile x coordinate (first tile is at (0,0), second at (1,0) etc.. ).
int	z	Tile z coordinate.
int	rotation	Rotate tile by 90 degrees * value.
int	yoffset	Offset Y coordinates by this amount. In Int3 space, so if you have a world space offset, multiply by Int3.Precision and round to the nearest integer before calling this function.

Mesh	source	Source mesh, must be readable.
Int3	centerOffset	Assumes that the mesh has its pivot point at the center of the tile. If it has not, you can supply a non-zero centerOffset to offset all vertices.
int	width=1	width of the tile. In base tiles, not world units.
int	depth=1	depth of the tile. In base tiles, not world units.

Int3[]	vertices
int []	triangles
List<Int3>	outVertices
List<int>	outTriangles

List<IntPoint>	poly
List<int>	intersectingCutIndices
List<Cut>	cuts
Pathfinding.ClipperLib.PolyTree	result

List<NavmeshCut>	navmeshCuts
GraphTransform	transform
IntRect	cutSpaceBounds
int	perturbate
bool	anyNavmeshAdds

Poly2Tri.Polygon	polygon
