Detailed Description

A WorldWithRank is a world where the karts are ranked.

This is the base class for races and battle modes - all of which rank the kart. A class using this as a subclass must call setKartPosition(kart id, position) and this class is used to access the ranks from other objects. This class adds a convenient rescue implementation: a kart is rescued to the closest start point. This is useful for battle, soccer, ... modes. Linear world defines its own rescue functions and will overwrite this.

Member Function Documentation

◆ beginSetKartPositions()

void WorldWithRank::beginSetKartPositions ( )

This function must be called before starting to set all kart positions again.

It's mainly used to add some debug support, i.e. detect if the same position is set in different karts.

◆ endSetKartPositions()

void WorldWithRank::endSetKartPositions ( )

Called once the last position was set.

Note that we should not test if all positions were set, since e.g. for eliminated and finished karts the position won't be set anymore.

◆ getKartAtDrawingPosition()

virtual AbstractKart * WorldWithRank::getKartAtDrawingPosition ( unsigned int  p) const

Returns the kart at which position (start from 1) to draw race icon.

pPosition of the kart.

Reimplemented in SoccerWorld.

◆ getKartAtPosition()

AbstractKart * WorldWithRank::getKartAtPosition ( unsigned int  p) const

Returns the kart with a given position.

pThe position of the kart, 1<=p<=num_karts).

◆ getRescuePositionIndex()

unsigned int WorldWithRank::getRescuePositionIndex ( AbstractKart kart)

Determines the rescue position for a kart.

The rescue position is the start position which is has the biggest accumulated distance to all other karts, and which has no other kart very close. The latter avoids dropping a kart on top of another kart. This is the method used

kartThe kart that is going to be rescued.
The index of the start position to which the rescued kart should be moved to.

Implements World.

Reimplemented in CaptureTheFlag, LinearWorld, SoccerWorld, and TutorialWorld.

◆ getScoreForPosition()

int WorldWithRank::getScoreForPosition ( int  p)

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

pPosition (starting with 1).

Reimplemented in FollowTheLeaderRace.

◆ getSectorForKart()

int WorldWithRank::getSectorForKart ( const AbstractKart kart) const

Gets the sector a kart is on.

This function returns UNKNOWN_SECTOR if the kart_id is larger than the current kart sector. This is necessary in the case that a collision with the track happens during resetAllKarts: at this time m_kart_track_sector is not initialised (and has size 0), so it would trigger this assert. While this normally does not happen, it is useful for track designers that STK does not crash.

kartKart for which to return the sector.

◆ getTrackSector()

TrackSector * WorldWithRank::getTrackSector ( unsigned int  kart_index) const

Returns the track_sector object for the specified kart.

kart_indexWorld index of the kart.

◆ init()

void WorldWithRank::init ( )

call just after instanciating.

can't be moved to the contructor as child classes must be instanciated, otherwise polymorphism will fail and the results will be incorrect

Reimplemented from World.

Reimplemented in CaptureTheFlag, EasterEggHunt, FollowTheLeaderRace, FreeForAll, LinearWorld, SoccerWorld, and ThreeStrikesBattle.

◆ isOnRoad()

bool WorldWithRank::isOnRoad ( unsigned int  kart_index) const

Returns true if the kart is on a valid graph quad.

kart_indexIndex of the kart.

◆ reset()

void WorldWithRank::reset ( bool  restart = false)

This function is called before a race is started (i.e.

either after calling init() when starting a race for the first time, or after restarting a race, in which case no init() is called.

Reimplemented from World.

Reimplemented in CaptureTheFlag, EasterEggHunt, FollowTheLeaderRace, FreeForAll, LapTrial, LinearWorld, SoccerWorld, and ThreeStrikesBattle.

◆ setKartPosition()

bool WorldWithRank::setKartPosition ( unsigned int  kart_id,
unsigned int  position 

Sets the position of a kart.

This will be saved in this object to allow quick lookup of which kart is on a given position, but also in the kart objects.

kart_idThe index of the kart to set the position for.
positionThe position of the kart (1<=position<=num karts).
false if this position was already set, i.e. an inconsistency in kart positions has occurred. This is used in debug mode only to allow the calling function to print debug information.
