Hi all, I work a lot on processing and roborealm and i reach this point:
I can't communicate with serial from roborealm to processing because I have arduino connected to processing also, and it gives an error. for this reason I work like this:
i can create a txt file with roborealm and save into a value, like the x value of a detected man in camera. The file appears like this:
COGX 39293489382901923903920910921......
variable is made by 3 numbers
(i can't understand how processing can understand this and split values automatically)
Code:
Code:

String[] lines = loadStrings("vision.txt");
int time = lines.length - 1;
int got = Integer.parseInt(lines[time]);
println(got);
if got > 300 println("hi")  

with this i get:
340
HI
340
HI
......

My problem is that i have to take always the last value to detect in real time men movements, for this reason i wrote:  int time = lines.length - 1;

if I start processing all is ok, when I open roborealm suddenly processing give sthis error
ERROR:
numberFormatException : for input string ""

If i write
int got = Integer.parseInt(lines[lines.length]):
it gives this error: Arrayindexoutofbound: and a number..
it i write
int got = Integer.parseInt(lines[lines.length - the number got in the previous error]):
it works with roborealm opened also, but when roborealm does the first value save (when detect something) processing gives again the first error....


if i ask to stamp lines it stamps all lines from the first to the last, and i can se in real time the values saved by roborealm with no problem. Now i have to understand how can i take the last value without problems

Please help me the graduation exam is near and i would like to add this application to my robot!!!
