Detailed Description

The timer.

The timer allows you to manage game events by duration, rather than on a frame-by-frame basis. This simple version of the timer is based on the Windows API function timeGetTime, which is notoriously inaccurate but perfectly adequate for a simple game demo.

Member Function Documentation

void CTimer::beginframe

(

void

)

Freeze the time returned for the duration of this frame.

This is the signal that a new animation frame has begun, so that the timer can return the same time value for the duration of this frame.

int CTimer::elapsed	(	int &	start,
		int	interval
	)

Has interval ms elapsed since start?

The elapsed function is a useful function for measuring repeating time intervals. Given the start and duration times, this function returns TRUE if the interval is over, and has the side-effect of resetting the start time when that happens, thus setting things up for the next interval.

Parameters

start	start of time interval
interval	duration of time interval

Returns

TRUE if time interval is over

int CTimer::GetLevelElapsedTime

(

)

Get elapsed time since the level started.

Returns

Level elapsed time.

int CTimer::GetLevelStartTime

(

)

Get time that the level started.

Returns

Level start time.

int CTimer::time

(

)

Return the time in ms.

Get current time.

Returns

Current time since start in milliseconds.
