Detailed Description

An implementation of World, based on LinearWorld, to provide the Follow-the-leader game mode.

Member Function Documentation

◆ getKartsDisplayInfo()

void FollowTheLeaderRace::getKartsDisplayInfo ( std::vector< RaceGUIBase::KartIconDisplayInfo > *  info)
virtual

Sets the title for all karts that is displayed in the icon list.

In this mode the title for the first kart is set to 'leader'.

Reimplemented from LinearWorld.

◆ getScoreForPosition()

int FollowTheLeaderRace::getScoreForPosition ( int  p)
virtual

Returns the number of points for a kart at a specified position.

Parameters
pPosition (starting with 1).

Reimplemented from WorldWithRank.

◆ getStartTransform()

const btTransform & FollowTheLeaderRace::getStartTransform ( int  index)
virtual

Returns the start coordinates for a kart with a given index.

Parameters
indexIndex of kart ranging from 0 to kart_num-1.

Reimplemented from World.

◆ init()

void FollowTheLeaderRace::init ( )
virtual

Called immediately after the constructor.

Here functions that use World::getWorld() as well as overridden functions.

Reimplemented from LinearWorld.

◆ raceHasLaps()

virtual bool FollowTheLeaderRace::raceHasLaps ( )
inlinevirtual

Returns if this type of race has laps.

Reimplemented from LinearWorld.

◆ terminateRace()

void FollowTheLeaderRace::terminateRace ( )
virtual

Called at the end of a race.

Updates highscores, pauses the game, and informs the unlock manager about the finished race. This function must be called after all other stats were updated from the different game modes.

Reimplemented from World.

◆ useFastMusicNearEnd()

virtual bool FollowTheLeaderRace::useFastMusicNearEnd ( ) const
inlinevirtual

Returns if faster music should be used at the end.

Reimplemented from World.

Member Data Documentation

◆ m_is_over_delay

float FollowTheLeaderRace::m_is_over_delay
private

A timer used before terminating the race.

◆ m_last_eliminated_time

float FollowTheLeaderRace::m_last_eliminated_time
private

Time the last kart was eliminated.

It is used to assign each kart a 'finish' time (i.e. how long they lasted).
