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

getFrameRate

public float getFrameRate()

Description copied from class: Timer

Returns the "calls per second". If this is called every frame, then it will return the "frames per second".

Specified by:

getFrameRate in class Timer

Returns:

The "calls per second".

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()
