OpenProcessing can't import zip from Processing 2.0b1

in General Discussion • Other • 1 year ago

I teach a class and use OpenProcessing.org

The instructions, here: http://www.openprocessing.org/sketch/upload don't work for Processing 2.0. The upload fails. NOTE: This isn't a library thing. Even just a super simple sketch like one line of code:

ellipse(100,100,100,100);

Will fail to upload. What are the proper instructions to upload Processing 2.0 sketches to OpenProcessing?

Thank You!

That's because 2.0b1 doesn't support applet export, which OpenProcessing (largely) depends on.

If you look at the File menu in both 1.5.1 and 2.0b1, you'll see that 1.5.1 has Export Applet and Export Application, while 2.0 only has the latter. The Export button used to correspond to Export Applet but, without this feature being present, it points to Export Application.

To get around this, you can use OpenProcessing's Processing.js implementation (you'll need to sign in in order to save it).

Processing.js is considerably different from Processing's "Java" mode:

As the name suggests, it is built on top of JavaScript instead of Java.
As a result of this, only the functionality present in Processing's reference will function correctly.
When using OpenProcessing, you'll have to copy and paste the code into the web browser.
You can't use most (if not all) libraries, although more support for it is being built.

That was, essentially, the downsides. Let's not forget the benefits:

Processing.js applications run on top of HTML5's <canvas> element.
They can be embedded into any web page (yes, that's right: any web page).
You don't have to install Java to run them.
Let's face it: Java Applets are on their way out, and HTML5 is on its way in, which is the reason that 2.0 dropped support for them in the first place.

As you can see, many people (including myself) are in favor of this change. It is important to note that Java is not on its way out, but that applets are. I hope that more Java functionality will be added in the future. And, if you still want to use applets, just go back to 1.5.1; it works perfectly fine.

Many thanks

As a Math teacher I use (Geogebra) applets on a daily basis. For me, applets are the perfect way of publishing and sharing. For stand-alone applications I would never thought about using Processing.

But your suggestion is most useful. I have downloaded 1.5.1.
