So, I'm kinda new here, this is my first thread, i was strugelling with this project for like 2 weeks now until i decided to come here, so i hope you guys can help me

The project Thread in MakeMagazine :
http://makezine.com/2012/08/10/build-a-touchless-3d-tracking-interface-with-everyday-materials/

So, i reached the point were i built the hardware and compiled the software with the arduino ad i started receiving data on the serial port screen, the problem is with the processing software. each time i compile the code it gives me errors with some functions and declarations, i have no idea in java language so i cant do anything actually

 

And the errors are?
My mind reading hat is in the shop

 

Sry, my bad
they are actually more than one, the first is : "the function readstringuntil(char) does not exist"

 

what version of processing? 2.1?
I think there was a bug in processing that accidentally removed that function.. Try an older version..
