Exporting processing sketch issue

Processing Coding Questions

Hi, I’m trying to export my sketch as frame images in order to make a movie. However, when I do, only the background of my sketch comes up. Have I missed something? I’ve used saveFrame in line 73.

Traditionally, one would put a call to saveFrame() at the end of draw(), not in the middle of it. You can’t save an image of things you haven’t drawn yet!

Thankyou! Just realised my error

You can also use the VideoExport library available in the Contribution manager. Check the examples as it is straight forward to use.
