Hello! I was wondering if it was possible to run like a processing sketch (or maybe even something more simplified) within a processing sketch. I would preferably use the Python mode but Java mode is fine too. :slight_smile: Anyway, I know that the open() can be used to open applications in a new w…

For Python Mode sketches (".pyde"), you might ask its dev if there’s a way to load & run those sketches from within another “.pyde” sketch: [image] jdf/processing.py Write Processing sketches in Python. Contribute to jdf/processing.py development by creating an account on GitHub. …

You cannot literally run a sketch within a sketch, but you can definitely write something where that appears to be the case. This involves writing an alternative base class to PApplet, copying all the methods you want to support and instead making them draw to a PGraphics, and then loading the sketc…

OK, offscreen PGraphics! :smile: It’s similar, it obviously has to be, but not using the primary graphics. And there are a few other differences to make it work as if the offscreen is a primary.

Thanks for the advice! I have not heard of PApplet… Ill have to look into it. It sounds interesting! :smiley:

Every sketch you write is a PApplet. You’ll definitely need to get your head around what that is and what it does to take this idea further,

[image] neilcsmith: Every sketch you write is a PApplet . You’ll definitely need to get your head around what that is and what it does For those wishing to do so – from the Processing javadocs: PApplet Base class for all sketches that use processing.core. The Window Size and Full Screen …

Inspired by this thread I tried my hand on a way to run multiple Processing sketches at the same time, spawned from a “parent” sketch. Then the secondary sketches are made invisible, and the parent sketch retrieves their graphic content. Could be a start to what @Repet is after. Downside is that mo…

Events are only part of the issue - your win[..].get() won’t be threadsafe either, and depending on renderer might work, work most of the time, work some of the time, or crash. Note the part in the Javadoc @jeremydouglass posted about the Processing Animation Thread - you now have five of them! …

Guess I got lucky with simple sketches. I’m not an expert on multithreading, but would this naive code make it thread safe? For this to fully work, there should be a way to synchronise all the animation threads across all the PApplet instances. PWindow[] win; public void settings() { size(600,…
