Detailed Description

This class is a two-way interface between the script language and its parent controller.

There are functions that either the parent controller will call on the script interface (such as tick() ) and there will be functions the script interface will call on the parent controller to inform the parent of status updates and for data access.

virtual void DtScriptInterface::addPostSetDataCallback ( const std::string &  setDataType, DtScriptFunctionReferencePtr  functionReference  )

virtual

Adds a callback to be invoked after the specified type of set data request is executed.

virtual void DtScriptInterface::removePostSetDataCallback ( const std::string &  setDataType, DtScriptFunctionReferencePtr  functionReference  )

virtual

Remove a callback invoked after the specified type of set data request is executed.

virtual void DtScriptInterface::clearPostSetDataCallbacks ( )

virtual

Clear all post-set data request callbacks.

This will remove set data request callbacks that would be invoked this tick.

static void DtScriptInterface::postSetDataCallback ( DtSimMessage *  msg, void *  usr  )

static

Callback registered to the set data manager.

This callback will clone the DtSimMessage and add a post tick entry to the sim manager to invoke any lua callback functions registered for the specific set data request type.

virtual void DtScriptInterface::processPostSetData ( DtSimMessage *  msg )

virtual

static void DtScriptInterface::postTickCallback ( void *  usr )

static

Invokes any post-set data request callbacks for set data requests executed this tick.

Removes itself as a post-tick entry on the DtSimManager, so it is only invoked when there is work to do.

virtual void DtScriptInterface::processPostTick ( )

virtual

virtual void DtScriptInterface::invokePostSetDataCallback ( DtScriptFunctionReferencePtr  functionReference, DtSetDataRequestMessage *  setDatRequest  )

pure virtual

Implement to invoke the function referenced by functionReference.

setDatRequest contains the information to be set. If a script interface implementation will not make use of post-set data request callbacks, this can be a no-op.

Implemented in DtLuaScriptInterfaceImpl.

virtual double DtScriptInterface::getTerrainAltitude ( const double  lat, const double  lon, bool &  dataAvailable, std::string &  surface  ) const

virtual

Gets the terrain height at the given location.

This function always makes a non-blocking call to the terrain interface (see documentation for DtTerrainInterface), even if dataAvailable is null; if dataAvailable is not null, then it is filled in with the result from the terrainInterface call indicating whether the altitude data is valid.

Note that in the Lua interface, dataAvailable and surface are pure_out_values, meaning that the arguments are not included in the function call, but are provided as additional return values of the function. E.g. use: height, valid, surfaceType = getTerrainAltitude(lat, lon)

virtual double DtScriptInterface::getTerrainAltitudeBelow ( const DtLocation3D &  point, bool &  available, std::string &  surfaceString  ) const

virtual

Same as getTerrainAltitude, but gets the terrain below the input point, not the highest terrain at the xy of the input point.

virtual double DtScriptInterface::getGroundAltitude ( const double  lat, const double  lon, bool &  isWater, bool &  dataAvailable  )

virtual

Gets the height of the ground at the given location.

If this point on the terrain is ground, then the value will be the same as that returned by getTerrainAltitude. However, if the terrain is water, then this function will return the altitude of the sea floor instead of the altitude of the water surface. This function always makes a non-blocking call to the terrain interface (see documentation for DtTerrainInterface), even if dataAvailable is null; if dataAvailable is not null, then it is filled in with the result from the terrainInterface call indicating whether the altitude data is valid.

Note that in the Lua interface, dataAvailable and surface are pure_out_values, meaning that the arguments are not included in the function call, but are provided as additional return values of the function.

virtual void DtScriptInterface::chordIntersectionDebug ( const DtLocation3D &  startLoc, const DtLocation3D &  endLoc  )

virtual

Script function for debugging chord-terrain intersections.

virtual bool DtScriptInterface::doesChordHitTerrain ( const DtLocation3D &  pt1, const DtLocation3D &  pt2, bool &  dataAvailable  ) const

virtual

Determines if the chord formed by (point1, point2) intersects the terrain.

The ground surface and features are considered. Returns a boolean indicating whether the LOS is blocked, and provides a flag indicating if the result is valid (the terrain data was available). This function always makes a non-blocking call to the terrain interface (see documentation for DtTerrainInterface), even if dataAvailable passed in is null. The intersectionTime parameter is a number in [0,1] indicating where along the line segment the intersection occurred.

bool DtScriptInterface::chordIntersectsTerrain	(	const DtLocation3D &	pt1,
		const DtLocation3D &	pt2,
		bool &	dataAvailable,
		DtLocation3D &	intersection
	)		const

Like chordIntersectsTerrain() Returns boolean if terrain is blocked.

On return, if dataAvailable is true, the terrain data was available (paged in). If dataAvailable is false, the terrain wasn't paged in yet and the result is inconclusive. If dataAvailable is true, then intersection will contain the location where terrain obstructs the chord from pt1 to pt2

virtual DtLocation3D DtScriptInterface::findClosestPointToRoad ( const DtLocation3D &  point, double  searchRadius, bool &  dataAvailable, bool &  success, DtLocation3D &  endA, DtLocation3D &  endB, double &  offsetToOutsideLane  ) const

virtual

virtual std::list<std::string> DtScriptInterface::getDynamicTerrainFeatureChangeTypes ( const DtLocation3D &  location, double  radius, bool &  dataVailable  )

virtual

Returns a list of the dynamic terrain feature change types in the specified area.

virtual std::list<DtLocation3D> DtScriptInterface::getDynamicTerrainFeatureLocationsForChangeType ( const std::string &  changeType, const DtLocation3D &  location, double  radius, bool &  dataVailable  )

virtual

Returns a list of the locations of dynamic terrain features with the given change type in the specified area.

virtual std::list<std::string> DtScriptInterface::getDynamicTerrainFeatureValuesForChangeType ( const std::string &  changeType, const DtLocation3D &  location, double  radius, bool &  dataVailable  )

virtual

Returns a list of the possible values for the given change type for dynamic terrain features in the specified area.

virtual void DtScriptInterface::changeDynamicTerrain ( const std::string &  changeType, const std::string &  changeValue, const DtLocation3D &  location, double  radius  )

virtual

Causes the given change at the specified area of the terrain.

bool DtScriptInterface::forcesHostile	(	std::string	force1,
		std::string	force2
	)

virtual double DtScriptInterface::gaussian ( )

virtual

Returns a number drawn from a standard Gaussian distribution.

virtual void DtScriptInterface::scriptTaskComplete ( bool  success )

If a set data request is executed while invoking callbacks, add it to this vector instead of mySetDataMessages.
