Public Methods

Return	Name	Description
	`FPSCounter` `inline`	Initialise the counter with all zeroes.
`void`	`reset` `inline`	Reset all counters and the SMA window to zero.
`void`	`tick` `inline`	Record a new frame and update the FPS estimate. Must be called once per frame. Updates `fps` and increments `frames`.
