Detailed Description

The DtDetonationManager class exists to centralize the processing of detonation interactions.

Components register with the detonation manager, providing a pointer to a DtVrfObject as well as the objects global designator, and a damage adjudication function to call when the detonation affects the registered vrfobject. The detonation manager determines the entity or entities the detonation affects, and notifies them and only them through the supplied callback functions.

With regards to detonation interactions, for a result of "entity proximate", where the entity is specified as the target, or for a result of simply "detonation", the range to the detonation is determined, and the damage probability is determined using a surface of "front" and an angle of incidence of 0. The detonation manager fills in a detonation context with all the appropriate information, and looks up the entity to see if it has registered a callback. If so, it calls the registered callback, supplying the detonation context.

When a detonation manager receives a detonation of type DtDetResDetonation (sent by the indirect fire actuator for artillery), it again fills in the detonation context, but then calls all appropriate entities with registered callbacks.

Constructor & Destructor Documentation

DtDetonationManager::DtDetonationManager ( DtSimManager & simManager )

Constructs the detonation manager.

Parameters

simManager A pointer to the simulation manager for the simulation.

virtual DtDetonationManager::~DtDetonationManager ( )

virtual

The destructor.

Removes the DtDetonationInteraction::removeCallback from the exercise connection.

DtDetonationManager::DtDetonationManager ( const DtDetonationManager & orig )

private

Not defined! copy constructor.

Member Function Documentation

virtual bool DtDetonationManager::init ( )

virtual

Initializes the detonation manager.

clears all managed lists
registers for detonation callbacks with the exercise connection

Returns: a boolean signifying success or failure.

virtual bool DtDetonationManager::reinitialize ( )

virtual

Resets the detonation manager to initial state.

Removes any registered callbacks from the exercise connection
calls init to initialize the manager.

Returns: a boolean signifying success or failure.

See Also: init

virtual bool DtDetonationManager::registerDirectDetonation	(	DtVrfObject &	entity,
		DtGlobalObjectDesignator	entityId,
		void *	callbackObject,
		DtDamageAdjudicationFunction	func
	)

virtual

Entities that wish to receive detonation notifications (technically, it is usually the actuators which register for the entity) call these functions.

Use this function to register interest in direct detonations ie entity impact or

entity proximate detonations. Supplies the entity, the entity ID, a callback function and a pointer to the actuator (void *)

virtual bool DtDetonationManager::registerCollateralDetonation	(	DtVrfObject &	entity,
		DtGlobalObjectDesignator	entityId,
		DtSimMunition	munition,
		double	maxDamageRadius,
		void *	callbackObject,
		DtDamageAdjudicationFunction	func
	)

virtual

Use this function to register interest in collateral detonations ie ground detonations from indirect fire, missile detonations or direct fire detonations that would cause collateral damage to nearby entities.

Supplies the entity, the entity ID, the munition being used, it's maximum radius that it can cause damage to the entity, a callback function, and a pointer to the actuator (void *). The munition and maximum damage radius are stored in the collateralDetonationTargetInfoPtr's damageMap keyed by munition.

virtual bool DtDetonationManager::unRegisterDirectDetonationTarget ( DtVrfObject & entity )

virtual

Removes the entity from the detonation manager's container of detonation targets.

Parameters

entity the address of the entity to be unregistered.

Note: If the entity pointer is NULL, then nothing is unregistered.

Returns: a boolean indicating the success or failure of the unregistration.

virtual bool DtDetonationManager::unRegisterCollateralDetonationTarget ( DtVrfObject & entity )

virtual

virtual bool DtDetonationManager::unRegisterCollateralDetonationCallback	(	DtVrfObject &	entity,
		void *	callbackObject,
		DtDamageAdjudicationFunction	func
	)

virtual

Removes the given entity callback from the detonation manager's container of detonation target callbacks.

virtual double DtDetonationManager::lookupMunitionInCollateralDetonationMap	(	const DtDetonationCallbackInfo &	target,
		const DtSimMunition &	munition
	)

virtual

If the munition is found returns the maximum damage radius of the munition.

virtual void DtDetonationManager::sendDetonationInteraction ( DtDetonationInteraction & detonation )

virtual

Send the fully initialized detonation interaction.

static void DtDetonationManager::detonationCallback	(	DtDetonationInteraction *	detInter,
		void *	usr
	)

staticprotected

The callback that processes detonation interactions.

Calls processDetonation to actually process the detonation interaction.

Parameters

detInter	the detonation interaction to process
usr	a void pointer to a DtDetonationManager. As this is a static function, this is provided when this function is registered in order to be able to properly handle the callback.

See Also: init; processDetonation

static void DtDetonationManager::uuidChangeCallback	(	const DtVrfObjectUUIDChangedCallbackInfo &	change,
		void *	usr
	)

staticprotected

virtual void DtDetonationManager::processUUIDChange ( const DtVrfObjectUUIDChangedCallbackInfo & change )

protectedvirtual

virtual void DtDetonationManager::processDetonation ( const DtDetonationInteraction & detonation )

protectedvirtual

Process the detonation interaction by properly creating a detonation context for the interaction, and then notifying all the appropriate entities of the detonation.

For entity impact and proximate detonations, only the specified entity is notified. For detonation and ground proximate interactions, all entities within range are notified. For ground impacts, entities in range are only notified if the munition was a missile.

virtual const DtPhysicalWorld* DtDetonationManager::physicalWorld ( ) const

protectedvirtual

Returns: A pointer to the current physical world. This is guaranteed to either be a valid pointer or 0.

virtual DtPhysicalWorld* DtDetonationManager::physicalWorld ( )

protectedvirtual

virtual Coordinate_System* DtDetonationManager::coordinateSystem ( )

protectedvirtual

Returns: A pointer to the current coordinate system object to use. This is guaranteed to either be a valid pointer or 0.

virtual const Coordinate_System* DtDetonationManager::coordinateSystem ( ) const

protectedvirtual

virtual void DtDetonationManager::processCollateralDetonationForEntitiesInRange ( DtDetonationContext & detonationContext )

protectedvirtual

Checks all entities who've registered interest in the munition in detonation context Checks the range of the detonation to the entity against the entity's maximumDamageRadius for that munition.

If the detonation is within that range then tell that entity to process this detonation and determine any collateral damage from it.

bool DtDetonationManager::testInvariant ( ) const

protected

The Detonation Manager's invariant:

The simulation manager must have a valid physical world in a valid state.

Returns: A boolean signifying whether or not the variant is still valid.
