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.

Constructor & Destructor Documentation

◆ ~DemoWorld()

DemoWorld::~DemoWorld ( )


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

Member Function Documentation

◆ abortDemo()

void DemoWorld::abortDemo ( )

Signals that the demo should be aborted.

◆ enableDemoMode()

static void DemoWorld::enableDemoMode ( float  time = 1.0f)

Enables demo mode after the specified amount of time (default 1 second).

timeThe idle time after which demo mode should be started.

◆ enterRaceOverState()

void DemoWorld::enterRaceOverState ( )

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 ProfileWorld.

Sets the list of tracks that is to be used.

tracksList of track identifiers.

◆ update()

virtual void DemoWorld::update ( int  ticks)

Counts the number of frames.

ticksnumber of physics time steps - should be 1.

Reimplemented from ProfileWorld.

◆ updateIdleTimeAndStartDemo()

bool DemoWorld::updateIdleTimeAndStartDemo ( float  dt)

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

dtTime step size, which is added to the idle time.
true if a demo is started.

Member Data Documentation

bool DemoWorld::m_abort

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

True if the next race is to be a demo race.

◆ m_max_idle_time

float DemoWorld::m_max_idle_time = std::numeric_limits<float>::max()
