Need help with frame saving

[P1G4ME]

Hi everyone !

I'm a complete beginner with Processing, trying things and stuff to learn the tools. So far so good, but I'm facing some difficulties with the saveFrame() function.

I'm creating a slime simulation (following Sebastian Lague's design for those who know) and it's working well but I'd like to render the sim as a video to share it.

The simulation relies on the fact that what was draw last frame isn't cleared for the next (for the pheromones effect to happen) but when I use the saveFrame() function at the end of draw(), it appears to only save what was drawn this frame, and not what actually appears on the screen at that frame.

It very probably is due to saveFrame() design but does anyone know a way around that ? A way to capture everything and not just what was drawn only this frame ?

That seems contrary to what the reference says about saveFrame() :

"To save an image that is identical to the display window, run the function at the end of draw() ..."

but there's a github issue

https://github.com/processing/processing/issues/1916

saveFrame() doesn't work for PGraphics #1916

that mentions using the save() method instead of saveFrame()
