Detailed Description

This class is used to show a demo of STK (e.g.

after being idle for a certain amount of time, or on certain command line options. This allows STK to be used as a demo in a shop.

DemoWorld::~DemoWorld ( )

virtual

Destructor.

Resets the flag that the next race is a demo mode.

time	The idle time after which demo mode should be started.

enterRaceOverState()

inlinevirtual

Returns identifier for this world.

Sets the number of laps to use in demo mode.

m_num_laps is from ProfileWorld.

setTracks()

void DemoWorld::setTracks ( const std::vector< std::string > &  tracks )

static

Sets the list of tracks that is to be used.

Parameters

tracks

List of track identifiers.

update()

virtual void DemoWorld::update ( int  ticks )

inlinevirtual

Counts the number of frames.

Parameters

ticks

number of physics time steps - should be 1.

Reimplemented from ProfileWorld.

updateIdleTimeAndStartDemo()

bool DemoWorld::updateIdleTimeAndStartDemo ( float  dt )

static

Updates the current idle time by dt.

If the accumulated idle time is large enough, a demo race is started.

Parameters

dt	Time step size, which is added to the idle time.

Returns

true if a demo is started.

Member Data Documentation

m_abort

bool DemoWorld::m_abort

private

True if demo mode should be aborted, e.g.

because a key was pressed.

m_demo_tracks

std::vector< std::string > DemoWorld::m_demo_tracks

staticprivate

The list of tracks to use for demo mode.

They will be picked randomly, but each track will be picked once before one track is repeated.
