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. |

| 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::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.
| 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. |
| void Kaim::IQuery::SetTraverseLogicUserData |
( |
void * |
traverseLogicUserData | ) |
|
|
inlineinherited |
Should be set for queries templated by a traverse logic, useless otherwise.
| Vec3f Kaim::BaseDiskCastQuery::m_arrivalPos3f |
|
protected |
Updated during processing to indicate the final position of the disk at the end of the cast:
Updated during processing to indicate the NavMesh triangle that corresponds to m_arrivalPos3f.
The imprecision of floating-point calculations may render this triangle invalid after moving m_arrivalPos3f back from the point of collision.
Updated during processing to indicate the triangle edge the disk collided with (if a collision is detected).
| Vec3f Kaim::BaseDiskCastQuery::m_collisionPos3f |
|
protected |
Updated during processing to indicate the position of the collision point between the disk and the NavMesh border (if a collision has been detected).
The database on which the query will be performed. Set in Initialize(), do not directly modify.
The maximum distance the disk will travel.
| Vec2f Kaim::BaseDiskCastQuery::m_normalizedDir2d |
|
protected |
A normalized vector representing the direction in which the disk 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.
| PositionSpatializationRange Kaim::BaseDiskCastQuery::m_positionSpatializationRange |
|
protected |
Modified by the query within Advance().
Do not modify.
Before reading m_processStatus, always ensure IsInAQueryQueue() returns false.
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.
An element from the DiskCanGoQueryType enumeration that indicates if a degraded query should be run when the the starting point lies within the NavMesh but the radius collides with the border of the NavMesh.
Updated during processing to indicate the result of the query.
| KyFloat32 Kaim::BaseDiskCastQuery::m_safetyDist |
|
protected |
When a collision is detected, the collision point is moved back along m_normalizedDir2d by this distance, to ensure that the final arrival position will lie within the valid area of the NavMesh.
| Vec3f Kaim::BaseDiskCastQuery::m_startPos3f |
|
protected |
The start position of the disk.
The NavMesh triangle that corresponds to m_startPos3f. Can be set as an input, or retrieved as an output of the query.
| void* Kaim::IQuery::m_traverseLogicUserData |
|
inherited |
This userData is typically passed by the Bot.
