DtGroundMoveToDestinationControllerComponent is a controller that provides a kinematics-based model of an automotive system that converts throttle, brake, and steering into orientation, acceleration, velocity, and position.
End User Description: It moves the entity of which it is a part towards a user-specified (or other controller specified) destination. Uses Descriptor Type: DtGroundMoveToDescriptor

| DtComponentDescriptor * | desc = 0, |

(const DtString&,DtVrfObject*,DtSimManager*,
| name | Reader writer name of this component. |
| owner | The DtVrfObject that owns this component |
| simManager | The simulation manager (provides access to terrain, message interface, simulation clock). |

Looks at the value on myCollisionAvoidancePort, and if there is a value and the destination point is within the bounding volume of the collision object, setDestinationIsInsideObstruction(true) is called.
If setupDestination() returns true, then moveToDestination() is called, otherwise an error is printed.

|
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.

| destination | the position this object is trying to drive to in local coordinates. |
|
virtual |
Returns the current destination vector for the entity.
|
virtual |
Determines how fast we should go.
If the myNearDestination member variable is true (set by nearDestination()), the desired speed is the value of the approachSpeed parameter in the DtGroundMoveToDescriptor. If the entity is in reverse gear, then that approach speed is negated. If myNearDestination is false, then the entity�s ordered speed is returned.
Reimplemented in DtGroundMoveAlongControllerComponent, and DtGroundFollowEntityController.
|
virtual |
Determines the desired heading in the following manner: If the myNearDestination member variable is true (set by nearDestination()), the desired heading is in the opposite direction as the destination vector (described in setupDestinationVector()).
If the myNearDestination member variable is false, it calls headingAngleTo() to find the heading from the entity to the destination. In either case, if the current gear is DtAutoGearReverse, PI is added to heading before it is returned.
Reimplemented in DtGroundFollowEntityController.
|
virtual |
Sets myProcessState->myCurrentGear to DtAutoGearReverse or DtAutoGearForward based on sign of orderedSpeed().
If ordered speed is negative, DtAutoGearReverse is returned. If ordered speed is positive, DtAutoGearForward is returned. In either case, the member variable myProcessState->myCurrentGear is set to the appropriate value.
Reimplemented in DtGroundFollowEntityController.
|
virtual |
Determines if the entity is close enough to the destination that it should start slowing down (see findDesiredSpeed()).
nearDestination() calls calculateCurrentBrakingDistance(). If the myDistanceSquared member calculated in tick() is less than or equal to the square of the value provided in the near-distance parameter of the DtGroundMoveToDescriptor, or if it is less than the square of the current braking distance, nearDestination() sets myNearDestination to true. If the above is not true, nearDestination() sets myNearDestination to false. myNearDestination is returned to the calling function.
|
virtual |
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 |
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 destination this tick if it does not stop. myPassedDestination is set, and the value is returned to the calling function.
Reimplemented in DtGroundFollowEntityController.
|
virtual |
Set port values for stopping, and mark the task complete.
Reimplemented in DtGroundMoveAlongControllerComponent, DtGroundFollowEntityController, DtGroundPatrolBetweenController, and DtGroundPatrolRouteController.
|
virtual |
Calls determineGearSetting(), findDesiredSpeed() and findDesiredHeading() and then sets port values based on those results.
|
virtual |
Called to update task visualizations after every tick.
Implemented by subclasses.
Reimplemented from DtTaskControllerComponent.
Reimplemented in DtGroundMoveAlongControllerComponent.

This function ensures that the destination stored in the process state matches the member function.
Also calculates the destination in local coordinates from the world coordinates.
Reimplemented in DtGroundMoveAlongControllerComponent, DtGroundFollowEntityController, and DtGroundMoveToControllerComponent.
|
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.
Reimplemented in DtGroundFollowEntityController.
