Exit not work. And License Processing - #4 by Architector_4 in this
was suggested to read the FAQ
where you can find this
You can distribute your sketches all you want, and commercial projects are just fine too, however we place no warranty on the software (see the download page for the license shenanigans).
but you know that, even you export your processing sketch / lets say to a WIN10 app /
still the JAVA sketch code is there as clear text ( not compiled )
but for me processing is a learning environment
( or interactive teaching tool )
and not a production tool ( for commercial software products )
but good luck for you, hope you get rich and can give something back
https://processing.org/download/support.html
but allow me to say that adding this kind of question
somewhere in between your coding questions
is not the correct / efficient way at a forum
you could make a extra topic after a extensive research about that first, like using:
google is your friend
as that question definitely targets other active members as your topic header would attract.
