Smartbottom YaBB Newbies Offline Posts: 7	Using exit() without exiting a wrapper Feb 24th, 2009, 10:38pm   Hi folks, I'm trying to call a processing sketch and return to call a different processing sketch.  Unfortunately, calling exit() within the spawned sketch seems to kill my parent method.  Any ideas? ./A

I suppose the PDE keeps running because it spawns the sketch's applet in its own JVM. Either you do that, or you just remove exit() call from your sketches...

I don't know if exit() is eventually called after that.

What is the command you use? I just want to execute the lines which are in a secondary file into the main sketch. Can you explain me how? Thanks Ptijo

Despite the appearances, Processing sketches are compiled (behind the scene, in a temp dir) before running them. I think such compound sketches are made with an Java program.
