Class FixedFramerateGame

java.lang.Object
  com.jme.app.AbstractGame
      com.jme.app.FixedFramerateGame

public abstract class FixedFramerateGame
extends AbstractGame

FixedFramerateGame attempts to run the game at a fixed frame rate. The main loop makes every effort to render at the specified rate, however it is not guaranteed that the frame rate will not dip below the desired value. Game logic is updated at the same rate as the rendering. For example, if the rendering is running at 60 frames per second, the logic will also be updated 60 times per second. Note that setFrameRate(int) cannot be called prior to calling start() or a NullPointerException will be thrown. If no frame rate is specified, the game will run at 60 frames per second.

Constructor Detail

FixedFramerateGame

public FixedFramerateGame()

Method Detail

setFrameRate

public void setFrameRate(int fps)

Set preferred frame rate. The main loop will make every attempt to maintain the given frame rate. This should not be called prior to the application being start() -ed.

Parameters:

fps - the desired frame rate in frames per second

getFramesPerSecond

public float getFramesPerSecond()

Gets the current frame rate.

Returns:

the current number of frames rendering per second

start

public final void start()

Render and update logic at a specified fixed rate.
