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.

Uses Descriptor Type: DtRailPathControllerDescriptor

Parameters
nameReader writer name of this component.

simManagerThe simulation manager (provides access to terrain, message interface, simulation clock).
descThe component descriptor used to initialize this component.
parentRegistryPointer to the parent reader writer registry (the containing object that reads/writes this object).

Member Function Documentation

DtRailPathController& DtRailPathController::operator= ( const DtRailPathController orig)
private

Not Implemented.

virtual bool DtRailPathController::init ( )
virtual

Initial setup of component after creation.

Reimplemented from DtControllerComponent.

virtual bool DtRailPathController::createPSR ( )
virtual

Creates myProcessState data member, and adds it to our process state repository manager.

Passes in the name and type specified in the component descriptor (if they exist) to the DtVrfProcessStateRepository::createRepository factory method. If name and/or type is not specified, uses the appropriate default strings defined in procSRTypes.h.

virtual void DtRailPathController::preFirstTickInit ( )
virtual

This function can be overridden to initialize a component before it is ticked for the first time.

The implementation for this function is empty. It is called by timedTick if myFirstTick is true.

Reimplemented from DtSimComponent.

static void DtRailPathController::railTaskCallback ( DtSimMessage msg,
void *  usr,
DtSimTaskStatePtr  taskStatePtr 
)
static
virtual DtSimTaskStatePtr DtRailPathController::currentTaskState ( ) const
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.

static void DtRailPathController::taskCompleteReportCallback ( DtSimMessage msg,

virtual void DtRailPathController::processTaskCompleteReport ( DtSimMessage msg)
virtual
static void DtRailPathController::destinationChangedCallback ( const DtVrfObject obj,

)
static
virtual void DtRailPathController::processDestinationChanged ( const 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 ( const DtVrfObject obj,
void *  usr 
)
static

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

virtual void DtRailPathController::processObjectAboutToBeRemoved ( const DtVrfObject obj)
virtual
static void DtRailPathController::setLocationCompleteCallback ( const 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
virtual void DtRailPathController::tick ( )
