Class GLTimer

java.lang.Object
  com.jibberia.gl.util.GLTimer

public class GLTimer
extends java.lang.Object

GLTimer is a simple class for timing the math required to do 3D animation. Use it to separate time-related things from the frame rate.

Someday, this should also provide pause() and restart() methods. Basic usage:

 
public class MyOpenGLThing implements TimedRenderable {
        GLTimer timer;

        public MyOpenGLThing() {
                initStuff();
                timer = new GLTimer(this, 0.001f);
                while(running) {
                        render(); // render as fast as possible in the main loop
                }
        }

        public void updatePhysics() {
                // do motion-related math, ie:
                rotation += 0.06f;
        }
}

Constructor Detail

GLTimer

public GLTimer(TimedRenderable parent,
               float deltaSeconds)

Constructor for GLTimer. Pass in a TimedRenderable and a time interval, and it will call that class's updatePhysics() every time interval.

Parameters:

parent - an instantiated class that implements TimedRenderable (almost always 'this')

deltaSeconds - a float time interval in seconds to call updatePhysics() in the parent class

Method Detail

stop

public void stop()

Stop the timer forever. Use it to quit your program.
