		DtElementID	elementId,
		DtUniqueID	sceneObjectId,
		DtUniqueID	uniqueId,
		bool	useInstancing,

	)

CTOR.

virtual makVrv::DtShipFlagSwitchTickable::~DtShipFlagSwitchTickable ( )

virtual

DTOR.

Member Function Documentation

DtVector makVrv::DtShipFlagSwitchTickable::computeWindVec	(	DtSceneObject *	sceneObj,
		float	windDirRad
	)

Convert the wind angle to a directional vector.

virtual void makVrv::DtShipFlagSwitchTickable::update ( DtTime tNow )

virtual

Update the switch node based on the wind speed.

Implements makVrv::DtTickable.

void makVrv::DtShipFlagSwitchTickable::SetWindNodeSwitch ( double windSpeed )

virtual bool makVrv::DtShipFlagSwitchTickable::needsUpdate ( DtTime tNow )

virtual

The check function called by DtTickableManager to verify if an update is required.

If this function returns true, the DtTickableManager will then call update().

Parameters

[in] tNow is the current time-stamp.

Return values

true	if this object needs to be ticked.
false	otherwise.

Reimplemented from makVrv::DtTickable.

virtual void makVrv::DtShipFlagSwitchTickable::configure	(	osg::Node *	n,
		const rapidjson::Value &	windJsonData
	)

virtual

Configure the meta file tickable object.

unsigned int makVrv::DtShipFlagSwitchTickable::getSwitchIndexForSpeed ( double windSpeed )

Get the switch index based on the wind speed (km/h)
