dtComputeTileOffsetFromRotation()

NAVMESH_API void dtComputeTileOffsetFromRotation	(	const dtReal *	position,
		const dtReal *	rotationCenter,
		const dtReal	rotationDeg,
		const dtReal	tileWidth,
		const dtReal	tileHeight,
		int &	deltaX,
		int &	deltaY
	)

Compute XY offset caused by the given rotation

Parameters

[in]	position	Position to rotate. [(x, y, z)]
[in]	rotationCenter	Rotation center. [(x, y, z)]
[in]	rotationDeg	Rotation in degrees.
[in]	tileWidth	Tile width.
[in]	tileHeight	Tile height.
[out]	deltaX	Offset X in tile coordinates.
[out]	deltaY	Offset Y in tile coordinates.

dtNavMeshDataSwapEndian()

NAVMESH_API bool dtNavMeshDataSwapEndian	(	unsigned char *	data,
		const int	dataSize
	)

Swaps endianess of the tile data.

Parameters

[in,out]	data	The tile data array.
[in]	dataSize	The size of the data array.

Warning

This function assumes that the header is in the correct endianess already. Call dtNavMeshHeaderSwapEndian() first on the data if the data is expected to be in wrong endianess to start with. Call dtNavMeshHeaderSwapEndian() after the data has been swapped if converting from native to foreign endianess.

dtNavMeshHeaderSwapEndian()

NAVMESH_API bool dtNavMeshHeaderSwapEndian	(	unsigned char *	data,
		const int	dataSize
	)

Swaps the endianess of the tile data's header (dtMeshHeader).

Parameters

[in,out]	data	The tile data array.
[in]	dataSize	The size of the data array.

dtTransformTileData()

NAVMESH_API bool dtTransformTileData	(	unsigned char *	data,
		const int	dataSize,
		const int	offsetX,
		const int	offsetY,
		const dtReal	tileWidth,
		const dtReal	tileHeight,
		const dtReal	rotationDeg,
		const dtReal	bvQuantFactor
	)

Offset and rotate around center the data in the tile

Parameters

[in,out]	data	Data of the tile mesh. (See: dtCreateNavMeshData)
[in]	dataSize	Data size of the tile mesh.
[in]	offsetX	X offset in tile coordinates.
[in]	offsetY	Y offset in tile coordinates.
[in]	tileWidth	Tile width.
[in]	tileHeight	Tile height.
[in]	rotationDeg	Rotation in degrees.
