Types

type FrameRater

type FrameRater struct {
	// contains filtered or unexported fields
}

FrameRater implements a frame rate controller

func NewFrameRater

func NewFrameRater(targetFPS uint) *FrameRater

NewFrameRater returns a frame rate controller object for the specified number of target frames per second

func (*FrameRater) FPS

func (f *FrameRater) FPS(t time.Duration) (float64, float64, bool)

FPS calculates and returns the current measured FPS and the maximum potential FPS after the specified time interval has elapsed. It returns an indication if the results are valid

func (*FrameRater) Start

func (f *FrameRater) Start()

Start should be called at the start of the frame

func (*FrameRater) Wait

func (f *FrameRater) Wait()

Wait should be called at the end of the frame If necessary it will sleep to achieve the desired frame rate
