Detailed Description

A SkyNode derived class used as a container for displaying a planet with its moons (if any).

Unlike PlanetMoons derived from SkyComponent PlanetMoonsNode represents both planet and moons. Ths PlanetNode shouldn't be instantiated outside of this class (exception is AsteroidsItem). Although all SkyNodes are "movable" objects (they change transform matrix to move across the SkyMapLite) this class is just a container that provides z-order for moons and planets that change their positions on their own.

A container for planets and moons that provides z-order.

Constructor & Destructor Documentation

PlanetMoonsNode()

PlanetMoonsNode::PlanetMoonsNode	(	KSPlanetBase *	planet,
		RootNode *	parentNode )

Constructor.

Parameters

planet	pointer to planet object
parentNode	pointer to the RootNode. It is needed for PointSourceNodes that use textures, which are cached in RootNode.

Definition at line 15 of file planetmoonsnode.cpp.

~PlanetMoonsNode()

PlanetMoonsNode::~PlanetMoonsNode

Member Function Documentation

addMoons()

void PlanetMoonsNode::addMoons ( PlanetMoons * planetMoons )

inline

Add object of type PlanetMoons to this node.

Parameters

planetMoons

PlanetMoons component

Definition at line 46 of file planetmoonsnode.h.

hide()

void PlanetMoonsNode::hide ( )

overridevirtual

Hides both planet and its moons.

Reimplemented from SkyNode.

Definition at line 37 of file planetmoonsnode.cpp.

update()

void PlanetMoonsNode::update ( )

overridevirtual

If planet has any moons first updateMoons() is called then the planet is updated.

Reimplemented from SkyNode.

Definition at line 31 of file planetmoonsnode.cpp.

updateMoons()

void PlanetMoonsNode::updateMoons

(

)

Update position of moons if planet has them.

To allow z-ordering we need to change the structure of node tree by removing all child nodes of this tree and adding them again so that moons that are behind the planet are before the m_planetNode in the hierarchy and all others are appended after m_planetNode.
