Member Function Documentation

virtual void Kaim::IQuery::Advance ( WorkingMemory *  workingMemory )

pure virtualinherited

This function is called by the QueryQueue to process one step on the query.

One call to Advance should be short (< 0.1ms as too long). It's Advance() responsibility to update m_processStatus. If the query is atomic, one call to Advance() will fully perform the query and set m_processStatus to QueryDone. If the query is time-sliced, several calls to Advance() will be needed to complete the query. the first call should set m_processStatus to Kaim::QueryInProcess and the last one to Kaim::QueryDone.

Parameters

workingMemory

Sandbox memory used to perform queries.

Implemented in Kaim::DynamicNavMeshQuery, Kaim::SpatializedPointCollectorInAABBQuery< SpatializedPointCollectorFilter >, Kaim::SpatializedPointCollectorInAABBQuery< Kaim::AvoidanceComputerCollectorFilter >, Kaim::SegmentCastQuery< TraverseLogic >, Kaim::SegmentCanGoQuery< TraverseLogic >, Kaim::TriangleFromPosQuery, Kaim::DiskCastQuery< TraverseLogic >, Kaim::MultipleFloorTrianglesFromPosQuery, Kaim::BestGraphVertexPathFinderQuery< VertexFinderLogic >, Kaim::DiskExpansionQuery< TraverseLogic >, Kaim::RayCastOnSegmentQuery< TraverseLogic >, Kaim::CircleArcSplineComputationQuery, Kaim::AStarQuery< TraverseLogic >, Kaim::FindFirstVisiblePositionOnPathQuery< TraverseLogic >, Kaim::TriangleFromPosAndTriangleSeedQuery, Kaim::RayCastFull3dQuery, Kaim::CollisionRayCastQuery, Kaim::RayCastQuery< TraverseLogic >, Kaim::InsidePosFromOutsidePosQuery< TraverseLogic >, Kaim::MoveOnNavMeshQuery< TraverseLogic >, Kaim::NearestBorderHalfEdgeFromPosQuery< TraverseLogic >, Kaim::DiskCanGoQuery< TraverseLogic >, Kaim::RayCanGoOnSegmentQuery< TraverseLogic >, Kaim::DiskCollisionQuery< TraverseLogic >, Kaim::RayCanGoQuery< TraverseLogic >, and Kaim::MonodirectionalRayCanGoQuery< TraverseLogic >.

void Kaim::BaseRayCanGoQuery::BindToDatabase

(

Database *

database

)

Binds the query with database, clears inputs and results, sets the configuration to defaults.

bool Kaim::IQuery::CanBeInitialized ( ) const

inlineinherited

In the case of a query processed in a QueryQueue, this must be tested before initializing the query, to prevent modifying the query during the process.

void* Kaim::IQuery::GetTraverseLogicUserData ( ) const

inlineinherited

Gets m_traverseLogicUserData.

virtual QueryType Kaim::BaseRayCanGoQuery::GetType ( ) const

inlinevirtual

Get query type.

Implements Kaim::IQuery.

void Kaim::BaseRayCanGoQuery::Initialize	(	const Vec3f &	startPos,
		const Vec3f &	destPos
	)

Sets m_startPos3f, m_destPos3f. Clears inputs and results, leaves configuration unchanged.

void Kaim::IQuery::Initialize ( )

inlineinherited

Should be called by the derived class prior to perform the query or to push it in a QueryQueue.

BindToDatabase() must have been called once before. It sets m_processStatus to QueryNotStarted. The query can be pending or in-progress in a query queue, then calling Initialize() is an error. CanBeInitialized() can be called to test this.

bool Kaim::IQuery::IsInAQueryQueue ( ) const

inlineinherited

Returns true if the query is currently registered in a QueryQueue.

If true, you must not push it again in QueryQueue (even the same one). If false, you must not try to cancel it from the QueryQueue.

bool Kaim::IQuery::IsSafeToReadResult ( ) const

inlineinherited

Returns true if the query has been processed, is no longer in a queue, and OnDone (if there is one) has been called.

If true, it's guaranteed to be safe to read the results of this query. Will return false if the Query has been cancelled or has not yet been processed.

void Kaim::IQuery::OnDone ( )

inlineinherited

Calls m_onDone IOnDone::OnDone() if m_onDone is not null.

Called automatically by the QueryQueue during the World::Update() (in the FlushQueries() step) when this query has been completed. OnDone() is not called if the query is canceled. Note that the member m_onDone is reset to nullptr at the end of this function.

KyUInt32 Kaim::IQuery::PerformQueryBlocking ( WorkingMemory *  workingMemory = nullptr )

inherited

Calls Advance() untill the query is done.

Parameters

workingMemory

Sandbox memory used to perform queries. If not set, m_database.GetWorkingMemory() will be used.

Returns

the number of call to Advance() (timesliced iterations) it took to perform the query.

KyResult Kaim::IQuery::SendVisualDebug ( )

inherited

Sends the query to the NavigationLab.

Currently the implementation transform the query using a DisplayList, and the display list is shown only at the frame SendVisualDebug is called.

void Kaim::BaseRayCanGoQuery::SetComputeCostMode ( ComputeCostMode  computeCostMode )

inline

Determines whether or not the query computes the approximate cost of following the line segment.

If set to QUERY_COMPUTE_COST_ALONG_3DAXIS, the cost is calculated and stored in m_cost.

void Kaim::BaseRayCanGoQuery::SetDestTrianglePtr ( const NavTrianglePtr &  destTrianglePtr )

inline

If no m_destTrianglePtr is set, it will be automatically computed from m_destPos3f. Cleared by Initialize().

void Kaim::BaseRayCanGoQuery::SetDynamicOutputMode ( DynamicOutputMode  dynamicOutputMode )

inline

What type of data to collect and store in m_queryDynamicOutput.

Set to QUERY_SAVE_NOTHING in BindToDatabase().

void Kaim::BaseRayCanGoQuery::SetMarginMode ( RayCanGoMarginMode  marginMode )

inline

The margin mode to be used in this query to eventually ensure the ray is not too close to any NavMesh border.

void Kaim::BaseRayCanGoQuery::SetPositionSpatializationRange ( const PositionSpatializationRange &  range )

inline

range to compute trianglePtr from position.

Set to Database::GetPositionSpatializationRange() in BindToDatabase().

void Kaim::BaseRayCanGoQuery::SetQueryDynamicOutput ( QueryDynamicOutput *  queryDynamicOutput )

inline

Will receive and store the dynamic data collected during the query process.

Use SetDynamicOutputMode() to indicate what data to store. You pass an existing QueryDynamicOutput by calling SetQueryDynamicOutput() after Initialize(), but m_queryDynamicOutput can be assigned to a new QueryDynamicOutput instance if the memory is not big enough to hold the collected data. Set to nullptr in Initialize().

void Kaim::BaseRayCanGoQuery::SetStartTrianglePtr ( const NavTrianglePtr &  startTrianglePtr )

inline

If no m_startTrianglePtr is set, it will be automatically computed from m_startPos3f. Cleared by Initialize().

void Kaim::IQuery::SetTraverseLogicUserData ( void *  traverseLogicUserData )

inlineinherited

Sets m_traverseLogicUserData for queries that have a custom TraverseLogic, useless otherwise.
