Detailed Description

DtRailPathController is a controller that models movement along a generated path for an entity making use of any feature data or routes of the type specified in the path metric.

End User Description: This task controller component responds to path movement tasks by calculating the best path from the current position to the destination using it's rail path planner. It first determines if using feature data or routes is worth the effort or if the entity should just take the direct route. If the former, it finds the entry point and exit point onto and off of the network of feature data/routes and the calculates the most efficent route on the network between the entry point and exit point.

Once the path is calculated, a move location task is issued to the entity to move it using it's normal movement system to the entry point onto the network. Once on the network this controller will deactivate the entity's normal movment system and activate it's rail movement system. Then a rail move along subtask is issued to the DtRailMovementController to allow the entity to efficently move along the generated rail path without the weaving motion symtopmatic of the default move controllers. Once the subtask completes, this controller deactivates the rail system and reactivates the default movement system. If a task was planned to a named object, and that object changes location during the run of this task, the original path will be removed, and a new path will be planned.

Note
The entity will remain in place while it is planning a path. If the terrain is complex, the distance to the destination is large, or there is not much available processor this may be a lengthy process.

This component can be configured though its descriptor, the DtRailPathControllerDescriptor. See this class for information on altering the path planning parameters in the OPE file.

This component maintains its internal state in a DtRailPathControllerPSR.

virtual
Returns
Current execution state of the task. At the base class level, returns 0. Derived classes that have tasks with DtTaskState (data associated with execution of the task) may return a new DtTaskState instance, filled out with the appropriate information about the current task execution state. Task controllers that do not need to return task state do not need to override this function.

Reimplemented from DtSingleTaskControllerComponent.

virtual const char* DtRailPathController::type ( ) const
virtual

Returns a string identifies the class type of component.

Type values are defined in compTypes.h. DtSimComponent creation functions are registered with the DtSimComponentFactory using the type values as the key. Warning: this function should always return the same pointer and it should be valid forever. This means the data should be static.

Returns
DtRailPathControllerType

Implements DtTaskControllerComponent.

virtual void DtRailPathController::registerTaskMsgCallbacks ( )
virtual

Overridden to register interest in move to messages.

Reimplemented from DtTaskControllerComponent.

virtual
static void DtRailPathController::destinationChangedCallback ( DtVrfObject obj,

)
static
virtual void DtRailPathController::processDestinationChanged ( DtVrfObject obj)
virtual

Ensures that the destination stored in the ProcessStateRepository is consistent with the location of the destination control point.

Intended to be called only when the position of the control point has changed.

Note
Also invalidates the destination vector as the world position has changed.
static void DtRailPathController::objectAboutToBeRemovedCallback ( DtVrfObject obj,
void *  usr 
)
static

If the object being removed is the current destination, then the task is abandoned.

virtual void DtRailPathController::processObjectAboutToBeRemoved ( DtVrfObject obj)
virtual

If the object being removed is the current destination, then the task is abandoned.

static void DtRailPathController::setLocationCompleteCallback ( DtVrfObject ,
void *  usr 
)
static

Aborts any running path planning, or stops any move along subtask that has been started.

Restarts path planning using entity's new position.

virtual void DtRailPathController::processSetLocationComplete ( )
virtual

Aborts any running path planning, or stops any move along subtask that has been started.

Restarts path planning using entity's new position.

virtual void DtRailPathController::tick ( )

Main processing for component.

Uses the rail segment's first point as the start.

virtual bool DtRailPathController::isEntityOnRoad ( DtRailSegment railSegment) const
protectedvirtual

Uses the rail segment's first point as the start to determine if entity is on the road.

double DtRailPathController::maxSearchRadius ( const DtVector start,

virtual void DtRailPathController::registerDestinationChangedCallback ( )
protectedvirtual

Registers a vertices changed callback with the destination object named in the PSR.

Registers for a setLocation message.

virtual void DtRailPathController::unregisterDestinationChangedCallback ( )
protectedvirtual

Unregisters a vertices changed callback from the destination object named in the PSR.

virtual DtVrfObject* DtRailPathController::publishDebugPath ( DtRailSegmentList )
protectedvirtual

Creates a new VRF Object corresponding to the path generated by the path planner.

Returns the VrfObject pointer to the new route object. Used to visualize the generated path.

virtual void DtRailPathController::removeDebugPath ( )
protectedvirtual

Removes the VrfObject corresponding to the path that was published and whose name is stored in myPathName.

virtual bool DtRailPathController::setupPathToDestination ( const DtVector start,
const DtVector end 
)
protectedvirtual

uses the DtRailPathPlanner to calculate a path from start to end.

virtual void DtRailPathController::clearTask ( )
protectedvirtual

Overridden from DtTaskControllerComponent to clean up the path calculating thread, remove any generated path objects, and stop any subtasks if the current task is aborted.

Reimplemented from DtSingleTaskControllerComponent.

(const DtString&,DtVrfObject*,DtSimManager*,

Parameters
nameReader writer name of this component.
ownerThe DtVrfObject that owns this component
simManagerThe simulation manager (provides access to terrain, message interface, simulation clock).
