Okay, here are resources on the PApplet exit issue:

>
> I’ve done some digging – inspired by @GoToLoop and @quark – and have found a solution. Closing sketches in P2D and JAVA2D renderer modes calls the PApplet instance’s exitActual() method, which contains the line System.exit(0) – a static method – which terminates the currently running Java virtual machine. Overriding exitActual() with nothing (i.e. preventing the call to System.exit(0)) prevents sketches from closing others, fixing the issue, but introduces another problem in the case of P2D s…

Is there a way I can prevent this?

> hello, I am using Processing (3.2.3) in Eclipse and I have managed to produce a second PApplet window using using runSketch(). I would like to use the second window to control what goes on in the first (and vice versa as well) - so use PApplet 2 to control what’s going on in PApplet 1. I am not new to Processing but I am new to Eclipse and using full Java. So I am wondering how I may access classes which are being used by the other applet - ie. how would different PApplets share objects? Below …
