Constructor & Destructor Documentation

TileType	(	Int3[]	sourceVerts,
		int[]	sourceTris,
		Int3	tileSize,
		Int3	centerOffset,
		int	width = 1,
		int	depth = 1
	)

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

Create a new TileType.

First all vertices of the source mesh are offseted by the centerOffset. The source mesh is assumed to be centered (after offsetting). Corners of the tile should be at tileSize*0.5 along all axes. When width or depth is not 1, the tileSize param should not change, but corners of the tile are assumed to lie further out.

Parameters

source	The navmesh as a unity Mesh
width	The number of base tiles this tile type occupies on the x-axis
depth	The number of base tiles this tile type occupies on the z-axis
tileSize	Size of a single tile, the y-coordinate will be ignored.

Member Function Documentation

void Load	(	out Int3[]	verts,
		out int[]	tris,
		int	rotation,
		int	yoffset
	)

Load a tile, result given by the vert and tris array.

Warning

For performance and memory reasons, the returned arrays are internal arrays, so they must not be modified in any way or subsequent calls to Load may give corrupt output. The contents of the verts array is only valid until the next call to Load since different rotations and y offsets can be applied. If you need persistent arrays, please copy the returned ones.

Matrices for rotation.

Each group of 4 elements is a 2x2 matrix. The XZ position is multiplied by this. So

//A rotation by 90 degrees clockwise, second matrix in the array
(5,2) * ((0, 1), (-1, 0)) = (2,-5)
