Constructors, destructors, conversion operators
- FrameTimer(float logInterval, float avgInterval)
- Constructor.
Public functions
- void AddFrame()
- Adds a frame to the counter and calculates the interval since the previous one.
- void Suspend()
- Starts counting the suspension time.
- auto Resume() -> TimeStamp
- Drifts timers by the duration of last suspension.
-
auto GetTotalNumberFrames() const -> std::
uint32_t - Returns the total number of frames counted.
- auto GetLastFrameDuration() const -> float
- Returns the last frame duration in seconds between the last two subsequent calls to
addFrame() - auto GetFrameDuration() const -> float
- Returns current frame duration in seconds since the last call to
addFrame() -
auto GetFrameDurationAsTicks() const -> std::
uint64_t - Returns current frame duration in ticks since the last call to
addFrame() - auto GetAverageFps() const -> float
- Returns the average FPS during the update interval.
- auto GetTimeMult() const -> float
- Returns a factor that represents how long the last frame took relative to the desired frame time.
