Member Function Documentation

void ClearTile	(	int	x,
		int	z
	)

void CreateTileTypesFromGraph

(

)

void CutPoly ( Int3[]  verts, int[]  tris, ref Int3[]  outVertsArr, ref int[]  outTrisArr, out int  outVCount, out int  outTCount, Int3[]  extraShape, Int3  cuttingOffset, Bounds  realBounds, CutMode  mode = CutMode.CutAll | CutMode.CutDual, int  perturbate = 0  )

private

Cuts a piece of navmesh using navmesh cuts.

Note

I am sorry for the really messy code in this method. It really needs to be refactored.

void CutShapeWithTile	(	int	x,
		int	z,
		Int3[]	shape,
		ref Int3[]	verts,
		ref int[]	tris,
		out int	vCount,
		out int	tCount
	)

void DelaunayRefinement ( Int3[]  verts, int[]  tris, ref int  vCount, ref int  tCount, bool  delaunay, bool  colinear, Int3  worldOffset  )

private

Refine a mesh using delaunay refinement.

Loops through all pairs of neighbouring triangles and check if it would be better to flip the diagonal joining them using the delaunay criteria.

Does not require triangles to be clockwise, triangles will be checked for if they are clockwise and made clockwise if not. The resulting mesh will have all triangles clockwise.

void LoadTile	(	TileType	tile,
		int	x,
		int	z,
		int	rotation,
		int	yoffset
	)

Load a tile at tile coordinate x, z.

Parameters

tile	Tile type to load
x	Tile x coordinate (first tile is at (0,0), second at (1,0) etc.. ).
z	Tile z coordinate.
rotation	Rotate tile by 90 degrees * value.
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.

Vector3 Point2D2V3 ( Poly2Tri.TriangulationPoint  p )

private

TileType RegisterTileType	(	Mesh	source,
		Int3	centerOffset,
		int	width = 1,
		int	depth = 1
	)

Register that a tile can be loaded from source.

Parameters

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.
width	width of the tile. In base tiles, not world units.
depth	depth of the tile. In base tiles, not world units.
source	Source mesh, must be readable.

Returns

Identifier for loading that tile type

void ReloadInBounds

(

Bounds

b

)

Reloads all tiles intersecting with the specified bounds.

void ReloadTile	(	int	x,
		int	z
	)

Reload tile at tile coordinate.

The last tile loaded at that position will be reloaded (e.g to account for moved navmesh cut components)

static T [] ShrinkArray< T > ( T[]  arr, int  newLength  )

staticprotected

Returns a new array with at most length newLength.

The array will a copy of all elements of arr.

bool StartBatchLoad

(

)

Start batch loading.

Returns

True if batching wasn't started yet, and thus EndBatchLoad should be called, False if batching was already started by some other part of the code and you should not call EndBatchLoad
