	Creates an instance of the referee, using the static values to initialise it.
	Referee (const AbstractKart &kart)
	Creates an instance of the referee, using the static values to initialise it.
void	selectReadySetGo (int rsg)
	Selects one of the states 'ready', 'set', or 'go' to be displayed by the referee.
void	attachToSceneNode ()
	Make sure that this referee is attached to the scene graph.
void	removeFromSceneGraph ()
	Removes the referee's scene node from the scene graph, but still keeps the scene node in memory.
scene::IAnimatedMeshSceneNode *	getSceneNode ()
	Returns the scene node of this referee.

bool	isAttached () const
	Returns true if this referee is attached to the scene graph.
void	setAnimationFrameWithCreatedTicks (int created_ticks)

Detailed Description

This implements the referee, a character that is displayed at the start of the race holding a 'ready-set-go' traffic light (or so).

It contains various static functions and variables which are used to store the original mesh, offsets, rotation, ... of the referee. Each instance of Referee then has a scene node where the referee is shown. One instance of this object is used to display the referee for all(!) karts, i.e. the scene node is moved and rotated before rendering the view for each of the cameras. This reduces rendering effect somewhat, and helps making the startup less crowded.

Constructor & Destructor Documentation

Referee() [1/2]

Referee::Referee

(

)

Creates an instance of the referee, using the static values to initialise it.

This is the constructor used when a start referee is needed.

Referee() [2/2]

Referee::Referee

(

const AbstractKart &

kart

)

Creates an instance of the referee, using the static values to initialise it.

This is the constructor used when a rescue referee is needed.

Parameters

kart	The kart which the referee should rescue.

Member Function Documentation

attachToSceneNode()

void Referee::attachToSceneNode

(

)

Make sure that this referee is attached to the scene graph.

This is used for the start referee, which is removed from scene graph once the ready- set-go phase is over (it is kept in case of a restart of the race).

removeFromSceneGraph()

void Referee::removeFromSceneGraph

(

)

Removes the referee's scene node from the scene graph, but still keeps the scene node in memory.

This is used for the start referee, so that it is quickly available in case of a restart.

selectReadySetGo()

void Referee::selectReadySetGo

(

int

rsg

)

Selects one of the states 'ready', 'set', or 'go' to be displayed by the referee.

Parameters

rsg	0=ready, 1=set, 2=go.

setRotation()

void Referee::setRotation

(

const Vec3 &

hpr

)

Sets the rotation of the scene node (in degrees).

Parameters

hpr	Rotation in degrees.
