If the entity is tasked and the route exists, a vertices changed callback is added to it.

Otherwise, an object added callback is added for objectAddedCb.

Reimplemented from DtSimComponent.

virtual void DtAggregatedMoveAlongController::tick ( )
virtual

This components simulation tick.

Reimplemented from DtSimComponent.

static void DtAggregatedMoveAlongController::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 DtAggregatedMoveAlongController::processRouteChanged ( DtVrfObject obj)
virtual
virtual void DtAggregatedMoveAlongController::registerTaskMsgCallbacks ( )
virtual

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

Reimplemented from DtTaskControllerComponent.

static void DtAggregatedMoveAlongController::moveAlongCallback ( DtSimMessage msg,
void *  usr,
DtSimTaskStatePtr  taskStatePtr 
)
static
virtual bool DtAggregatedMoveAlongController::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 DtAggregatedMoveAlongController::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 DtAggregatedMoveAlongController::findDesiredSpeed ( )
virtual

Returns ordered speed of the entity.

virtual void DtAggregatedMoveAlongController::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().

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 DtAggregatedMoveAlongController::clearTask ( )
protectedvirtual

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

Reimplemented from DtSingleTaskControllerComponent.

virtual void DtAggregatedMoveAlongController::moveToDestination ( )
protectedvirtual

Attempts to move to the destination location. Override to provide movement functionality.

virtual void DtAggregatedMoveAlongController::invalidateDestinationVector ( ) const
protectedvirtual

Tells the component that any cached destination vector should be recalculated.

virtual double DtAggregatedMoveAlongController::distanceToDestination ( ) const
protectedvirtual
virtual bool DtAggregatedMoveAlongController::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 DtAggregatedMoveAlongController::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 DtAggregatedMoveAlongController::getDestination ( DtVector destination)
protectedvirtual

getDestination()

Parameters
destinationthe 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& DtAggregatedMoveAlongController::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.
See Also
setupDestinationVector
virtual void DtAggregatedMoveAlongController::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 DtAggregatedMoveAlongController::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 DtAggregatedMoveAlongController::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 DtAggregatedMoveAlongController::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 DtAggregatedMoveAlongController::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 DtAggregatedMoveAlongController::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 DtAggregatedMoveAlongController::getCurrentRouteSegment ( DtVector routeSegmentStart,
DtVector routeSegmentEnd 
) const
protectedvirtual
Returns
True if we are currently moving along a route segment, false otherwise.
Parameters
routeSegmentStartStarting point of route segment in local coordinates.
routeSegmentEndEnd point of route segment in local coordinates.
DtSimTaskStatePtr DtAggregatedMoveAlongController::currentTaskState ( ) const
protectedvirtual
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.
