Detailed Description

The RSOInterface1 class defines an abstract interface to an RSO instance.

Member Function Documentation

Calculate()

virtual void Calculate ( double  time )

pure virtual

The RSO Interface methods.

Perform component simulation. Any non-drawing activities can be performed here. Call this before PreDraw()

CloneObject()

virtual RSOInterface1 * CloneObject ( )

pure virtual

Returns a new instance of the RSO that is a clone of this object or NULL if not possible.

Draw()

virtual void Draw ( )

pure virtual

Draw the object via OpenGL Call this after PreDraw()

GetBoundingBox()

virtual bool GetBoundingBox ( Vector *  min, Vector *  max, const MatrixD *  transform = 0  )

pure virtual

Get the extents of the component when drawn with the given transformation matrix, as a coordinate system-aligned box

Parameters

min	If the method returns true, contains the point corresponding with the 1st corner of the box. If the method returns false, value is undefined.
max	If the method returns true, contains the point corresponding with the 2nd corner of the box. If the method returns false, value is undefined.
transform	Transformation matrix from A to B where A is the component's coordinate system and B is the coordinate system to compute the bounding box in. (If NULL then identity matrix is assumed)

Returns

true if the extents were calculated, false if the extents could not be calculated.

GetBoundingSphere()

virtual bool GetBoundingSphere ( Vector *  center, float *  radius  )

pure virtual

Get the bounding sphere for the component in the components coordinate system

Parameters

center	If the method returns true, contains the center point of the sphere. If the method returns false, value is undefined.
radius	If the method returns true, contains the radius of the sphere. If the method returns false, value is undefined.

Returns

true if the bounding sphere was returned, false if the bounding sphere is not available.

GetResource()

virtual const char * GetResource ( const char *  resourceName )

pure virtual

Get the string value for the given resource.

Implemented in RSOInterface2.

GetResources()

virtual const char * GetResources ( ResourceFilter *  filter = 0 )

pure virtual

Get a list of the resources for the component. Each resource is separated by a newline ('
') with the output controlled by filter. filter may be NULL in which case the default values are used.

HandleInput()

virtual bool HandleInput ( Event *  ev )

pure virtual

Allow the object to handle an event Returns true if the event was handled by the component

PreDraw()

virtual void PreDraw ( const OpenGLMatrices &  current, Culler &  culler  )

pure virtual

Calculate transformations and perform culling Call this before Draw()

SetEmittedEventHandler()

virtual bool SetEmittedEventHandler ( EmittedEventHandler *  handler )

pure virtual

Allow for handling events from inside the object. The emitted event handler will be passed events that are from inside the component

Parameters

handler

pointer to the EmittedEventHandler object to use or NULL to remove the current event handler.

Returns

true if this component may emit events, false if this component will never emit events.

SetResource()

virtual void SetResource ( const char *  resourceName, const char *  resourceVal  )

pure virtual

Set the string value for a given named resource.

Implemented in RSOInterface2.
