As the title states, this is the next iteration of my Sonar applet. I’ve added a “ping” collision sound, optimized the classes a little and added key commands to pause (P) the animation and show the FPS (D).  I also discovered the proper way to reference the sound files internally so it works as an applet and an application. You’ll notice there are 2 tracker lines now ... only the first one is used for collision testing, the second tracker line is simply a place holder for a feature I am trying to add.

I’m wanting to recreate the effect of the trailing blur pattern that often follows the main tracker line, something I’m sure we’ve all seen in movies. I’d like the effect to extend in a 90 degree arc. I’m pretty stumped on ways to do this at the moment, but I guess thats half the fun. If you are an experienced Java coder and have advice to share please do. =)

Here’s the source for the applet and app versions.
