PBox 2D

Pathy

Hello ! I need library PBox 2D master to work with the kinect . All that meeting did not work , install , but the sketch always says missing library in question. Someone can help me?

Chrisir

post your code

Chrisir

did you download and install the lib?

Not against library PBox 2D . She changed her name? Already tried to install , but says: "the package "pbox2d" does not exist...

Chrisir

did you try menue the manager?

Pathy

I did not understand ! What is this? I am a student and need to make a program work. I'm not a programmer , I'm still learning , sorry ! But this is very important for my final project.

MRASH420

I'm having thesame problem did you resolve it?

jeremydouglass

@MRASH420 --

1. What is the exact error message you are getting?
2. Did you already download and install the missing library, and if so how?

MRASH420

@jeremeydouglass

ive downloaded everything to do with pbox, jbox and box2d but nothing works im using the sketch from https://kinectsen.wikispaces.com/Processing+Kinect+Resources and the code is called kinect physics.

jeremydouglass

What is the exact error message you are getting?

kfrajer

After you install any libraries in Processing, I would run the provided examples to ensure the libraries are set properly. Then I will try running any other external code. Try running the examples first and if you get any errors, copy and paste the error you get here as part of your post. The more details you provide, the easier for forum goers to get back to you with quality feedback.

MRASH420

it says the class Pbox2d does not exist?

MRASH420

ive saved many library downloads of pbox2d and saved them into (library)-(sketchbook) ill send the hyperlink of the sketch im using please help

Try using "import shiffman/box2D.*" instead of import PBox2D".
