The SceneBounds class is a special kind of gem describing the bounds of scene. The shape of the bounds is a cube, with a given extent in each direction. The main reason that the bounds are also a gem is easier collision detection. If there are bounds around our scene every ray emitted into scene will hit something. Furthermore the collision with scene bounds can be processed in a way, that the player will lose if the player hits the bounds. More...

Constructor & Destructor Documentation

SceneBounds::SceneBounds ( QObject * parent = 0 )

explicit

Creates new SceneBounds. The extent of bounds is taken from config file.

Parameters

parent

SceneBounds::~SceneBounds ( )

virtual

Member Function Documentation

QList< LightRay * > SceneBounds::processRayIntersection	(	const LightRay &	ray,
		Scene *	scene
	)

overridevirtual

Override AbstractGem::processRayIntersection() in order to ensure the player loses hitting the bounds.

Parameters

ray	The ray hitting the bounds.
scene	The scene containing all lightrays.

Returns: Returns a QList containing only a GameLostRay, so the player will loose as soon as the player tries to move on returned ray.

Reimplemented from AbstractGem.

void SceneBounds::setPosition ( const QVector3D & position )

overridevirtual

Parameters

position This parameter will be ignored.

Reimplemented from AbstractGem.

void SceneBounds::setRotation ( const QQuaternion & rotation )

overridevirtual

setRotation Override AbstractGem::setRotation() in order to forbid rotating the bounds.

Parameters

rotation This parameter will be ignored.
