Run Processing Sketch without Startx

[eraldino]

Hello to everyone, I have processing on my Raspberry pi. I want to export the Sketch I made in Processing and make it run on my PI without the StartX environment.

What format should I export it in and How can I call the file from the command line without the StartX

I would also like to AutoStart the file sooner after I figure out how to open it in the command line.

Can you guys help me out?

ALSO: why is my processing sketch slow when I am playing it in Processing PDE environment?

You can't, sorry. Processing requires X11 because it either runs under:

• Java — in the case of “classic” Processing
• A modern web browser - for Processing.js

Make sure you're running Oracle Java for the fastest Classic Processing. Haven't tried the new browser with Processing.js.

cheers,
 Stewart

X can be used with any single program without starting the desktop using the xinit command and a simple script file. For a simple one window / one application environment, install matchbox-window-manager. Create a small script file in your home folder:

Code: Select all

#!/bin/sh
matchbox-window-manager &
yourapp

Make it executable and start you app with
xinit ./scriptname

I am running on Oracle Java but still its too damn slow to run a rotating matrix.

Try to run ControlP5Matrix on your raspberry pi and tell me if its slow or not.

I will try to do this. Can this be automatically started on boot up?

Yes, quite easily.

That's doing quite a lot of maths. Don't forget that the Raspberry Pi has roughly the same power as a 2009 iPhone 3GS …

Couldn't get it to run under Processing.js, though I didn't try very hard.

I exported a sketch in processing and run it in the terminal, after closing it I tried to run it again. Now I am getting an error that says java is not found

I tried java -version
and got:

bash: java: command not found

how can i fix this? they say its about a path thing but its very vague all the java files are gone in my processing folder too.

Whats happening to my java-oracle?
