#include <navgraphblobbuilder.h>

Class Description

This class allows you to build a NavGraph, which you can then add to the NavData for a sector.

This class is typically used in a custom post-processing phase after generating the NavMesh for a terrain.

Examples:: gamekit/Tutorial_CrowdDispersion.cpp, Tutorial_Generation_postProcess.cpp, and Tutorial_NavTag.cpp.

Deprecated ExclusiveNavTag
The term 'ExclusiveNavTag' was confusing or ambiguous, it is not exclusive as in DynamicNavTag::IsExclusive(). It means a uniquely used NavTag in the NavGraph, no other edge or vertex is expected to use this NavTag. Please use the Add*WithUnsharedNavTag functions instead.

		KyUInt32	endVertexIdx,
		KyUInt32	navTagIdx
	)

Adds a bidirectional edge that connects the specified vertices.

NOTE: this function will create two mono-directional edges. One from startVertexIdx to endVertexIdx and One from endVertexIdx to startVertexIdx the edge will be associated to the NavTag that is not supposed to be associated to other vertices or edges

Parameters

startVertexIdx	The index of the starting vertex for the edge, which was returned by AddVertex().
endVertexIdx	The index of the ending vertex for the edge, which was returned by AddVertex().
navTagIdx	The associated navTag index that has already been added to Graph

void Kaim::NavGraphBlobBuilder::AddBidirectionalEdgeWithoutNavTag	(	KyUInt32	startVertexIdx,
		KyUInt32	endVertexIdx
	)

No navTag will be associated to this edge.

Parameters

startVertexIdx	The index of the starting vertex for the edge, which was returned by AddVertex().

Note that the edge is mono-directional, from the startVertex to the endVertex. If you want your characters to be able to plan paths that go between the two vertices in either direction, you must add a second edge from the endVertex to the startVertex, or use AddBidirectionalEdgeWithoutNavTag() instead. the edge will be associated to the NavTag that is not supposed to be associated to other vertices or edges

Parameters

NavGraphBlob * Kaim::BaseBlobBuilder< NavGraphBlob >::Build ( BlobHandler< NavGraphBlob > & blobHandler )

inherited

This method:

Calls DoBuild() in COUNT mode to determine the amount of memory needed for the blob to be built.

Allocates the amount of memory in the specified BlobHandler.
Calls DoBuild() again, in WRITE mode, to actually build the blob in the buffer allocated by the BlobHandler.

Examples:: gamekit/Tutorial_CrowdDispersion.cpp, and Tutorial_NavTag.cpp.

void Kaim::BaseBlobBuilder< NavGraphBlob >::BuildFlatBlob ( NavGraphBlob & blob )

inherited

Simple way to use DoBuild in case of flat blob (that is, a blob that does not have a BlobArray or BlobRef)

void Kaim::BaseBlobBuilder< NavGraphBlob >::DoAllocAndBuildReferencedBlob	(	BlobBuffer *	blobBuffer,

virtual void Kaim::NavGraphBlobBuilder::DoBuild ( )

privatevirtual

Implement this function in any class that derives from BaseBlobBuilder.

Its responsibility is to set the data for each class member maintained by m_blob. In your implementation, use one of the macros sets supplied for this purpose:

BLOB_SET, sets the value of a single class member of m_blob.
BLOB_ARRAY and BLOB_ARRAY_COPY, sets up BlobArray members of m_blob.
BLOB_STRING, copies a string into a char* class member of m_blob.
BLOB_BUILD, recursively builds class members of m_blob that need to be built by their own BaseBlobBuilder class.

Implements Kaim::BaseBlobBuilder< NavGraphBlob >.

void Kaim::BaseBlobBuilder< NavGraphBlob >::DoBuildAllocatedBlob	(	BlobBuffer *	blobBuffer,
		NavGraphBlob *	blob
	)

inherited

For internal use. Use BLOB_BUILD instead.

BlobBuffer* Kaim::BaseBlobBuilder< NavGraphBlob >::GetBlobBufferToBuildThis ( )

inlineinherited

For internal use. Check if m_buildingPart == BUILDING_SHALLOW_PART and return this.

bool Kaim::BaseBlobBuilder< NavGraphBlob >::IsWriteMode ( )

inlineinherited

Indicates whether the builder is operating in COUNT mode or in WRITE mode.

This can be used in implementations of DoBuild().

void Kaim::NavGraphBlobBuilder::SetName ( const char * graphName )
