template<class TLogic >
void Kaim::MonodirectionalRayCanGoQuery< TLogic >::Advance ( WorkingMemory *  workingMemory)
inlinevirtual

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

It MUST NEVER, under any circumstances, take too long. As a guideline, consider 0.1ms as too long.

It is under the responsibility of this function to update m_processStatus. Obviously, if the query is atomic (i.e. not time-sliced), a 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
workingMemorySandbox memory used to perform queries.

Implements Kaim::IQuery.

template<class TLogic >
void Kaim::MonodirectionalRayCanGoQuery< TLogic >::BindToDatabase ( Database database)
inline

Binds the query with the specified Database, clears all the inputs and outputs and sets all other parameters to their default value (they may be changed by calling the corresponding write accessors.)

Parameters
databaseA pointer to the Database on which the query must be performed.
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.

template<class TLogic >
void Kaim::MonodirectionalRayCanGoQuery< TLogic >::Initialize ( const Vec3f startPos,
const Vec3f destPos 
)
inline

Sets an instance of this class with minimum input requirements.

Clears all the output, and let all other parameters unchanged. They may be changed by calling the corresponding write accessors.

Parameters
startPosSets the value of m_startPos3f.
destPosSets the value of m_destPos3f.
void Kaim::IQuery::Initialize ( )
inlineinherited

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

The query must have been bound to a Database before.

It sets m_processStatus to Kaim::QueryNotStarted. As some query framework components (such as QueryQueue) relies on these members, you cannot call SetUp() unless CanBeInitialized() returns true.

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 the OnDone function of the IOnDone object if provided.

Called automatically by the QueryQueue during the World::Update() (in FlushQueries() step) when this query has been completed.

Not called if this query is canceled.

Note that the member m_onDone is reset to KY_NULL at the end of this function.

template<class TLogic >
void Kaim::MonodirectionalRayCanGoQuery< TLogic >::PerformQuery ( WorkingMemory *  workingMemory = 0)
inline

Performs the query.

Parameters
workingMemorySandbox memory used to perform queries. If let to KY_NULL, the m_database internal WorkingMemory is used.
void Kaim::IQuery::PerformQueryBlocking ( WorkingMemory *  workingMemory = 0)
inherited

Process the query at once whether it is time-sliced or not.

Parameters
workingMemorySandbox memory used to perform queries. If let to KY_NULL, the m_database internal WorkingMemory is used.
template<class TLogic >
void Kaim::MonodirectionalRayCanGoQuery< TLogic >::SetComputeCostMode ( ComputeCostMode  computeCostMode)
inline

Write accessor for m_computeCostMode.

Call this method after BindToDatabase(), during which m_computeCostMode is set to its default value.

template<class TLogic >
void Kaim::MonodirectionalRayCanGoQuery< TLogic >::SetDynamicOutputMode ( DynamicOutputMode  savingMode)
inline

Write accessor for m_dynamicOutputMode.

Call this method after BindToDatabase during which member m_dynamicOutputMode is set to its default value.

template<class TLogic >
void Kaim::MonodirectionalRayCanGoQuery< TLogic >::SetMarginMode ( RayCanGoMarginMode  marginMode)
inline

Write accessor for m_marginMode.

Call this method after BindToDatabase(), during which m_marginMode is set to its default value.

template<class TLogic >
void Kaim::MonodirectionalRayCanGoQuery< TLogic >::SetPositionSpatializationRange ( const PositionSpatializationRange &  positionSpatializationRange)
inline

Write accessor for m_positionSpatializationRange.

Call this method after BindToDatabase(), during which m_positionSpatializationRange is set to its default value.

template<class TLogic >
void Kaim::MonodirectionalRayCanGoQuery< TLogic >::SetQueryDynamicOutput ( QueryDynamicOutput queryDynamicOutput)
inline

Write accessor for m_queryDynamicOutput.

Call this method after Initialize(), during which m_queryDynamicOutput is set to KY_NULL.

template<class TLogic >
void Kaim::MonodirectionalRayCanGoQuery< TLogic >::SetStartTrianglePtr ( const NavTrianglePtr startTrianglePtr)
inline

Set The NavMesh triangle that corresponds to m_startPos3f.

If a valid NavTrianglePtr is specified, this value will be used.

If no value is specified, it will be automatically computed during the query.

Call this method after Initialize(), during which it is cleared.

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

Should be set for queries templated by a traverse logic, useless otherwise.

Member Data Documentation

ComputeCostMode Kaim::BaseRayCanGoQuery::m_computeCostMode
protectedinherited

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.

KyFloat32 Kaim::BaseRayCanGoQuery::m_cost
protectedinherited

Updated during processing to store the cost of the line segment, if enabled by m_computeCostMode.

Database* Kaim::IQuery::m_database
inherited

The database on which the query will be performed. Set in Initialize(), do not directly modify.

Vec3f Kaim::BaseRayCanGoQuery::m_destPos3f
protectedinherited

The ending point of the line segment to be tested.

NavTrianglePtr Kaim::BaseRayCanGoQuery::m_destTrianglePtr
protectedinherited

The NavMesh triangle that corresponds to m_destPos3f. It will be computed automatically during the query.

DynamicOutputMode Kaim::BaseRayCanGoQuery::m_dynamicOutputMode
protectedinherited

Specifies the type of data stored in m_queryDynamicOutput.

QueryStatusInQueue Kaim::IQuery::m_inQueueStatus
inherited

Used by the QueryQueue. Do not modify.

RayCanGoMarginMode Kaim::BaseRayCanGoQuery::m_marginMode
protectedinherited

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

Ptr<IOnDone> Kaim::IQuery::m_onDone
inherited

The optional IOnDone instance to be called. Must be set manually by the user. See IOnDone.

PositionSpatializationRange Kaim::BaseRayCanGoQuery::m_positionSpatializationRange
protectedinherited

The altitude range around the position to use when determining m_startTrianglePtr and m_destTrianglePtr from the m_startPos3f and m_destPos3f.

QueryProcessStatus Kaim::IQuery::m_processStatus
inherited

Modified by the query within Advance().

Do not modify.

Before reading m_processStatus, always ensure IsInAQueryQueue() returns false.

Ptr<QueryDynamicOutput> Kaim::BaseRayCanGoQuery::m_queryDynamicOutput
protectedinherited

A ref-counted Ptr to a QueryDynamicOutput instance, used to store the data encountered during the query process.

You have to first call SetDynamicOutputMode(), after BindToDatabase() that set it to QUERY_SAVE_NOTHING by default and before processing the query, to define the data type you want to gather.

You can keep the Ptr for reuse and reassign it to another query by calling SetQueryDynamicOutput() after the BindToDatabase(), but in this case, be careful: the query may swap the underlying instance when processing if the provided buffer is to short. In this case, it is more sure to always update the Ptr when the query process is over.

QueryQueue* Kaim::IQuery::m_queue
inherited

Updated by the QueryQueue. Do not modify.

RayCanGoQueryResult Kaim::BaseRayCanGoQuery::m_result
protectedinherited

Updated during processing to indicate the result of the query.

Vec3f Kaim::BaseRayCanGoQuery::m_startPos3f
protectedinherited

The starting point of the line segment to be tested.

NavTrianglePtr Kaim::BaseRayCanGoQuery::m_startTrianglePtr
protectedinherited

The NavMesh triangle that corresponds to m_startPos3f. You can set it as an input or retrieve it as an output of the query.

void* Kaim::IQuery::m_traverseLogicUserData
inherited

This userData is typically passed by the Bot.
