disabling save when running as applets
Oct 6th, 2009, 3:24pm  
I am working on a set of sketches that need to run locally as well as an applet. When running from within the Processing environment, I need to use save() for screenshots.

But when running inside an applet, I need to disable the save otherwise the applet crashes.

I could certainly have two copies, but it is really too cumbersome at this point.

Is there any ways to detect whether I am running as an applet?
Or do you have any other idea for me to keep the same code, but enable/disable save()?

Thanks

There is a variable built in to test if your app is running in a web browser: 'online'.
Usage:

if (!online) {
 //save pic
}

I did that, but it crashes anyway. Here is my trivial sketch.

Quote:
ellipse(50,50,25,25);

// code used to capture screenshots
if(!online) save("sketch.png");




Any idea on how to make this work? I do not really understand why it would break, but it does.

It works for me.
Tested also with:
if (!online) println("Not on line"); else println("On line");
(result can be seen in the Java console).
Don't forget to remove the applet from the cache when updating it.
