Class LwjglTimer

java.lang.Object
com.jme3.system.Timer
com.jme3.system.lwjgl.LwjglTimer
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 Details

    • reset

      public void reset()
      Description copied from class: Timer
      Reset the timer to 0. Clear any tpf history.

      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.
