FpsHelper

Helper for measuring frames per second and setting static FPS. Usually needs to be located as field of game class.

struct FpsHelper {

Signal!(FpsHelper*) fpsUpdated;

double updateInterval;

double updateTime;

double deltaTime;

size_t fpsTicks;

double secondsAccumulator;

bool limitFps;

double timeLimit;

void update(double dt, double updateTime);

void sleepAfterFrame(double frameTime);

}

Functions

sleepAfterFrame void sleepAfterFrame(double frameTime): Undocumented in source. Be warned that the author may not have intended to support it.
update void update(double dt, double updateTime): Undocumented in source. Be warned that the author may not have intended to support it.

Variables

deltaTime double deltaTime;: Stores last delta time passed into update()
fps double fps;: Stores actual FPS value
fpsTicks size_t fpsTicks;: Stores amount of updates between
fpsUpdated Signal!(FpsHelper*) fpsUpdated;: Undocumented in source.
limitFps bool limitFps;: Undocumented in source.
maxFps uint maxFps;: Undocumented in source.
secondsAccumulator double secondsAccumulator;: Accumulates time before reaching update interval
timeLimit double timeLimit;: Delta time value will clamped to meet interval [0;timeLimit]. This can prevent from value lags when entering hibernation or resizing the window.
updateInterval double updateInterval;: fps will be updated each updateInterval seconds
updateTime double updateTime;: Stores update time passed trough update every updateInterval
