Member Function Documentation

DtHumanMoveAlongController& DtHumanMoveAlongController::operator= ( const DtHumanMoveAlongController &  orig )

private

Not Implemented.

virtual bool DtHumanMoveAlongController::init ( )

virtual

Init. Call immediately after construction.

Reimplemented from DtControllerComponent.

virtual DtString DtHumanMoveAlongController::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.

Returns

DtHumanMoveAlongControllerType

Implements DtTaskControllerComponent.

virtual void DtHumanMoveAlongController::preFirstTickInit ( )

virtual

If tasked, looks up the route and if it already exists, registers routeChangeCalledback as a vertices changed callback and calls setupDestination.

Otherwise, it adds objectAddedCb as an object added callback.

Reimplemented from DtSimComponent.

virtual void DtHumanMoveAlongController::tick ( )

virtual

If tasked, calls enableAllPorts on myCollisionAvoidancePortGroup, otherwise calls disableAllPorts.

Ticks the parent class, DtSingleTaskControllerComponent. If tasked and dT > 0, it will activate myHumanMovementControlOutputPortGroup and myDestinationOutputPort. If setupDestination() returns true, it calls moveToDestination() and otherwise it prints warning, deactivates all the ports and calls taskComplete().

Reimplemented from DtSimComponent.

static void DtHumanMoveAlongController::moveAlongCallback ( DtSimMessage *  msg, void *  usr  )

static

Instances of this component will register this callback with their own 'this' pointer as user data with the msg executive requesting notification of move-along tasks.

virtual void DtHumanMoveAlongController::processMoveAlongTask ( DtSimMessage *  msg )

virtual

Handle messages to move along a route or assume a move along task from another.

static void DtHumanMoveAlongController::routeChangedCallback ( DtVrfObject *  obj, void *  usr  )

static

Intended to be called only when the route has changed.

Note

Also invalidates the destination vector as the world position has changed.

virtual void DtHumanMoveAlongController::processRouteChanged ( DtVrfObject *  obj )

virtual

virtual void DtHumanMoveAlongController::registerTaskMsgCallbacks ( )

virtual

Overrides this so it can register it's interest in MoveAlong commands.

Reimplemented from DtTaskControllerComponent.

virtual bool DtHumanMoveAlongController::setupRoute ( )

virtual

Look up the route by name, and set myRoute if found.

Looks up the route in the Control Manager. If it does not find the route, it returns false. Otherwise, it sets the myRoute member to point to the object found. setupRoute() then checks the myRouteChanged flag. If myRouteChanged is true, it calls the route object’s resyncRouteState() member function to update the current DtRouteState. setupRoute() then returns true.

virtual bool DtHumanMoveAlongController::setupDestination ( )

virtual

Sets myControlPoint to the position of the route's current vertex.

If setupRoute() returns false, setupControlPoint() calls taskComplete() and returns false. Otherwise, it sets the position of the myControlPoint member variable to the position of myRoute’s current vertex. If myRouteHasChanged is true, setupGoalVector() is called, and myRouteHasChanged is set to false. true is then returned.

virtual double DtHumanMoveAlongController::findDesiredSpeed ( )

virtual

Returns ordered speed of the entity.

virtual void DtHumanMoveAlongController::stop ( )

virtual

Overrides to advance to the next vertex rather then actually stop when a vertex is reached.

Checks to see if the entity is currently moving to the last vertex in the route. If so, DtGroundMoveToControllerComponent::stop() is called. Otherwise, myProcessState->routeState()->next() is called, followed by setupControlPoint() and setupGoalVector().

static void DtHumanMoveAlongController::objectAddedCb ( DtVrfObject *  vrfObject, void *  usr  )

static

Calls processObjectAdded().

static DtSimComponent* DtHumanMoveAlongController::creator ( const DtString &  name, DtVrfObject *  owner, DtSimManager *  simManager, DtComponentDescriptor *  desc = 0, DtReaderWriterRegistry *  parentRegistry = 0  )

Creates and initializes port groups.

Reimplemented from DtSimComponent.

virtual bool DtHumanMoveAlongController::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 DtHumanMoveAlongController::doMoving ( )

virtual

Calls determineGearSetting(), findDesiredSpeed() and findDesiredHeading() and then sets port values based on those results.

virtual double DtHumanMoveAlongController::findDesiredHeading ( )

removes and deletes vertices from the vertex list in process state repository (calls process state repository's emptyRouteVertices()).

virtual void DtHumanMoveAlongController::processObjectAdded ( DtVrfObject *  vrfObject )

protectedvirtual

Checks given vrfObject against the route we're looking for.

If it is ours, registers a vertices-changed callback on the object. This way we can detect if the route changes while we're trying to follow it.

virtual void DtHumanMoveAlongController::clearTask ( )

protectedvirtual

Override to clear route name and route state data stored in myProcessState.

Reimplemented from DtSingleTaskControllerComponent.

virtual void DtHumanMoveAlongController::moveToDestination ( )

virtual double DtHumanMoveAlongController::distanceToDestination ( ) const

protectedvirtual

virtual bool DtHumanMoveAlongController::atDestination ( )

protectedvirtual

Are we within the at-distance parameter to the destination? If the myDistanceSquared member calculated in tick() is less than or equal to the square of the value provided in the at-distance parameter of the DtGroundMoveToDescriptor, atDestination() sets myAtDestination to true.

If the myDistanceSquared !<= at-distance, atDestination() sets myAtDestination to false. myAtDestination is returned to the calling function.

virtual bool DtHumanMoveAlongController::passedDestination ( )

protectedvirtual

Determines if the entity will pass the destination to which it is moving this frame if it continues at its current velocity and acceleration.

It dead-reckons its position. It calculates the vector that points from the entity to the destination It finds the dot product between this vector and destination vector, If that dot product is greater than 0.0, the entity will pass the destinationthis tick if it does not stop. myPassedDestination is set, and the value is returned to the calling function.

virtual bool DtHumanMoveAlongController::getDestination ( DtVector &  destination )

protectedvirtual

getDestination()

Parameters

destination

the position this object is trying to drive to in local coordinates.

Returns

true if it has a valid destination () or false if it is unable to determine it's destination.

Note

Used by other areas of the simulation to determine where this object is going. (Information)

virtual const DtVector& DtHumanMoveAlongController::destinationVector ( ) const

protectedvirtual

Returns the current destination vector for the entity.

Note

if the destination vector is currently invalidated, it recalculates it and sets it to valid.

virtual void DtHumanMoveAlongController::setupDestinationVector ( ) const

protectedvirtual

Sets up a vector from the current destination location to the entity's location to use in determining when/if the entity has passed its destination location.

This is done by subtracting the DtVector representing the destination's position from the one representing the entity’s position.

Note

Users should not use this function directly,and should instead use the invalidateDestinationVector and destinationVector functions. Should be a protected or even private function, but was left public to maintain the interface.

virtual double DtHumanMoveAlongController::atDistance ( ) const

protectedvirtual

Maximum distance at which entity is considered to be 'at' a route vertex.

Returns value stored in descriptor (if it exists), otherwise returns 1.0.

Returns

Returns maximum distance in meters from route vertex that entity is considered to be 'at' the vertex.

virtual bool DtHumanMoveAlongController::stayOnRoute ( ) const

protectedvirtual

If true, will attempt to closely follow route segments as it moves along a route.

If false, will only attempt to reach each waypoint in turn as it moves along the route.

Returns

Flag indicating whether or entity will attempt to closely follow route segments.

virtual double DtHumanMoveAlongController::minCorrectionDistance ( ) const

protectedvirtual

Maximum distance at which entity is considered to be 'at' a route vertex.

Returns

Minimum distance from route that entity will attempt to correct heading to stay on route segment. If entity is within this distance from route segment, it will move directly toward the next waypoint. In meters.

virtual double DtHumanMoveAlongController::maxCorrectionDistance ( ) const

protectedvirtual

Returns

Maximum distance from route that entity will attempt to correct heading to stay on route segment. If entity is within the min-correction-distance and max-correction-distance from the route segment, it will correct its heading toward the next waypoint in such a way that it 'pulls' the entity closer to the route as it travels. If distance from route segment is greater than this threshold, it will move directly toward the next waypoint. In meters.

virtual double DtHumanMoveAlongController::maxCorrectionAngle ( ) const

protectedvirtual

Returns

Maximum absolute angular corrections entity will make to attempt to move the entity closer to the route segment. In radians. Default is ~45 degrees.

virtual bool DtHumanMoveAlongController::getCurrentRouteSegment ( DtVector &  routeSegmentStart, DtVector &  routeSegmentEnd  ) const

protectedvirtual

Returns

True if we are currently moving along a route segment, false otherwise.

Parameters

routeSegmentStart	Starting point of route segment in local coordinates.
routeSegmentEnd	End point of route segment in local coordinates.
