Constructor & Destructor Documentation

FrameCounter::FrameCounter ( void )

Initializes the variables.

The first start-time is set.

Definition at line 13 of file FrameCounter.cpp.

FrameCounter::~FrameCounter ( void )

Destructor.

Definition at line 24 of file FrameCounter.cpp.

int FrameCounter::getFrameRateAverage ( void )

brief Returns the last calculated framerate.

The framerate is actualized every second.

Definition at line 32 of file FrameCounter.cpp.

long FrameCounter::getFrameStart ( void )

Definition at line 36 of file FrameCounter.cpp.

float FrameCounter::getFrameTimeAverage ( void )

Returns the time needed for drawing one frame.

The time is an average value calculated by the last frames per seconds value.

Definition at line 44 of file FrameCounter.cpp.

long FrameCounter::getFrameTimeCurrent ( void )

Returns the time passed since the last frame started.

Definition at line 51 of file FrameCounter.cpp.

long FrameCounter::getFrameTimeLast ( void )

Returns the time passed since the last frame started.

Definition at line 60 of file FrameCounter.cpp.

long FrameCounter::getTime ( void )

Definition at line 64 of file FrameCounter.cpp.

void FrameCounter::newFrame ( void )

Increases the counted number of frames.

Needs to be called everytime when a new frame is painted to the screen.

Definition at line 72 of file FrameCounter.cpp.

void FrameCounter::update ( void )

Updates the current framerate if one second has passed since the last update.

The elapsed time is calculated with the glutGet function which counts the milliseconds since start of the game.
