Detailed Description

Time is critical to a 3D game. The TimeClock watches and monitors it, and returns the time between frames. It also counts frames.

Timekeepings is surprisingly complex.

The computation of light from the sun or moon is also part of the time class.

Public Member Functions

	Frames per second, based on a 1 second sample.
float	FastFps ()
	Frames per second, on the last 300 ms sample.
float	TotalFPS ()
	The frames per second since Lilith was started.
float	CalcVelocity (float vel)
float	CalcChange (float value, float velocity, float minVal, float maxVal)
U32	Msec ()
	Get the current millisec since the time clock started.
float	HoursElapsed ()
	Get the gametime in floating point hours, instead of milliseconds.
void	CalcCalendarTime (U32 *days, U32 *hours, U32 *minutes, U32 *seconds)

float lilith3d::TimeClock::CalcVelocity

(

float

vel

)

[inline]

The function used to calc any value that is a function of time. Converts speed (m/s) to distance traved in this tick (m).

float lilith3d::TimeClock::CalcChange	(	float	value,
		float	velocity,
		float	minVal,
		float	maxVal
	)			[inline]

A subtle variant of CalcVelocity. Given a value, a velocity, and a range, change the value but keep it in range.
