public class LwjglTimer
extends Timer

Timer handles the system's time related functionality. This allows the calculation of the framerate. To keep the framerate calculation accurate, a call to update each frame is required. Timer is a singleton object and must be created via the getTimer method.

Method Detail

reset

public void reset()

Description copied from class: Timer

Reset the timer to 0. Clear any tpf history.

Specified by:

reset in class Timer

getTimeInSeconds

public float getTimeInSeconds()

Description copied from class: Timer

Returns the time in seconds. The timer starts at 0.0 seconds.

Overrides:

getTimeInSeconds in class Timer

Returns:

the current time in seconds

getTime

public long getTime()

Description copied from class: Timer

Returns the current time in ticks. A tick is an arbitrary measure of time defined by the timer implementation. The number of ticks per second is given by getResolution(). The timer starts at 0 ticks.

Specified by:

getTime in class Timer

Returns:

a long value representing the current time

See Also:

Timer.getTime()

getResolution

public long getResolution()

Description copied from class: Timer

Returns the resolution of the timer.

Specified by:

getResolution in class Timer

Returns:

the number of timer ticks per second

See Also:

Timer.getResolution()

getFrameRate

public float getFrameRate()

getFrameRate returns the current frame rate since the last call to update.

Specified by:

getFrameRate in class Timer

Returns:

the current frame rate.

getTimePerFrame

public float getTimePerFrame()

Description copied from class: Timer

Returns the time, in seconds, between the last call and the current one.

Specified by:

getTimePerFrame in class Timer

Returns:

Time between this call and the last one.

update

public void update()

update recalculates the frame rate based on the previous call to update. It is assumed that update is called each frame.

Specified by:

update in class Timer

toString

public java.lang.String toString()

toString returns the string representation of this timer in the format:

jme.utility.Timer@1db699b
