These functions are used by IQuery::SendVisualDebug() and also used by the NavigationLab to request remote execution: using VisualDebugClient::Send(IQuery*) to ask for a query to be executed using VisualDebugServer::Send(IQuery*) to send back the query result.
Queries that can be visual debug override these 3 functions.
By convenience, such queries provide a static function with the following signature: /code static Ptr<BaseBlobHandler> CreateStaticQueryBlobHandler(); /endcode

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
-
| workingMemory | Sandbox memory used to perform queries. |
Implements Kaim::IQuery.
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
-
| database | A 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.
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
-
| startPos | Sets the value of #m_startPos3f. |
| normalizedDir2d | Sets the value of #m_normalizedDir2d. |
| maxDist | Sets the value of #m_moveDistance. |
| 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.
Performs the query.
- Parameters
-
| workingMemory | Sandbox 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
-
| workingMemory | Sandbox memory used to perform queries. If let to KY_NULL, the m_database internal WorkingMemory is used. |
Set the minimal distance the arrival position should be from any NavMesh border.
Call this method after BindToDatabase(), during which #m_distanceToBoundary is set to its default value.
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.
| Vec3f Kaim::BaseMoveOnNavMeshQuery::m_arrivalPos3f |
|
protectedinherited |
Updated during processing to indicate the final position of the ray at the end of the cast.
- If no collision was detected, the result is the triangle arrived at by traversing the NavMesh in the direction of #m_normalizedDir2d.
- If a collision is detected, the result is derived from the collision point by backtracking along the orientation of #m_normalizedDir2d. This ensures #m_arrivalPos3f will be inside the boundaries of the NavMesh.
The database on which the query will be performed. Set in Initialize(), do not directly modify.
| KyFloat32 Kaim::BaseMoveOnNavMeshQuery::m_distanceToBoundary |
|
protectedinherited |
The minimal distance to NavMesh boundary the resulting position should be.
When the movement hits a boundary, we move back the final position so that it is at #m_distanceToBoundary meters from this boundary.
| KyFloat32 Kaim::BaseMoveOnNavMeshQuery::m_moveDistance |
|
protectedinherited |
Determines the maximum distance the disk will travel.
If this distance is too far from the starting point (approximately 32 times the length of a NavData cell), running the query can result in an integer overflow during calculation.
| Vec2f Kaim::BaseMoveOnNavMeshQuery::m_normalizedDir2d |
|
protectedinherited |
A normalized vector representing the direction the ray is cast.
| Ptr<IOnDone> Kaim::IQuery::m_onDone |
|
inherited |
The optional IOnDone instance to be called. Must be set manually by the user. See IOnDone.
Modified by the query within Advance().
Do not modify.
Before reading m_processStatus, always ensure IsInAQueryQueue() returns false.
Updated during processing to indicate the result of the query.
| Vec3f Kaim::BaseMoveOnNavMeshQuery::m_startPos3f |
|
protectedinherited |
The starting point of the line segment being tested.
The NavMesh triangle corresponding to #m_startPos3f. It can be an input, or it can be retrieved as an output of the query.
| void* Kaim::IQuery::m_traverseLogicUserData |
|
inherited |
This userData is typically passed by the Bot.
| bool Kaim::BaseMoveOnNavMeshQuery::m_visualDebugActivated |
|
inherited |
When toggle on, the query will send visual debug information.
