Detailed Description

An implementation of World, used for profiling only.

Constructor & Destructor Documentation

~ProfileWorld()

ProfileWorld::~ProfileWorld ( )

virtual

Sets profile mode off again.

Needed because demo mode's closing allows the player to continue playing STK. If we didn't set it off, profile mode would stay activated.

Member Function Documentation

createKart()

std::shared_ptr< AbstractKart > ProfileWorld::createKart ( const std::string &  kart_ident, int  index, int  local_player_id, int  global_player_id, RaceManager::KartType  kart_type, HandicapLevel  handicap  )

protectedvirtual

Creates a kart, having a certain position, starting location, and local and global player id (if applicable).

Parameters

kart_ident	Identifier of the kart to create.
index	Index of the kart.
local_player_id	If the kart is a player kart this is the index of this player on the local machine.
global_player_id	If the akrt is a player kart this is the index of this player globally (i.e. including network players).
init_pos	The start XYZ coordinates.

Reimplemented from World.

enterRaceOverState()

void ProfileWorld::enterRaceOverState ( )

virtual

This function is called when the race is finished, but end-of-race animations have still to be played.

In the case of profiling, we can just abort here without waiting for the animations.

Reimplemented from WorldStatus.

Reimplemented in DemoWorld.

getInternalCode()

virtual std::string ProfileWorld::getInternalCode ( ) const

inlinevirtual

Returns identifier for this world.

Reimplemented in DemoWorld.

isRaceOver()

bool ProfileWorld::isRaceOver ( )

virtual

The race is over if either the requested number of laps have been done or the requested time is over.

Reimplemented from StandardRace.

Reimplemented in DemoWorld.

setProfileModeLaps()

void ProfileWorld::setProfileModeLaps ( int  laps )

static

Enables profiling for a certain number of laps.

The race will end when all karts have done (at least) this number of laps.

Parameters

laps	The number of laps.

setProfileModeTime()

void ProfileWorld::setProfileModeTime ( float  time )

static

Enables profiling for a certain amount of time.

It also sets the number of laps to a high number (so that the lap count will not finish a race before the time is over).

Parameters

time	Time to profile a race for.

update()

void ProfileWorld::update ( int  ticks )

virtual

Counts the number of frames.

Parameters

ticks

number of physics time steps - should be 1.

Reimplemented from LinearWorld.

Reimplemented in DemoWorld.

Member Data Documentation

m_frame_count

int ProfileWorld::m_frame_count

private

Number of frames.

For statistics only.

m_num_laps

int ProfileWorld::m_num_laps = 0

staticprotected

In laps based profiling: number of laps to run.

Also used by DemoWorld.
