Method Detail

update

public void update()

Updates the last frame time and sets the lastTickCount to be the current

getLastTickCount

public long getLastTickCount()

Gets the start tick time that is stored for the last frame

Returns:

Returns the lastTickCount.

getCurrentTickCount

public long getCurrentTickCount()

Gets the current tick time.

Returns:

getTickResolution

public long getTickResolution()

Returns what the tick count needs to be for 1 second. Can be useful to see how long a frame actually took to render. Dividing lastFrameTime by tickResolution gets lastFrameTime in seconds (the same as getLastFrameTimeSeconds).

Returns:

getLastUpdateTimeSeconds

public double getLastUpdateTimeSeconds()

Get how long it was between the last update and this update. Useful in FPS and making speeds of items be time based (multiply speed by this amt)

Returns:

resetTimer

public void resetTimer()

getCurrentEngineTimeSeconds

public double getCurrentEngineTimeSeconds()

Returns the current engine time in seconds
