Hi, I have been messing with processing for 3 days now. Very new to programming...

I am trying to work with Roborealm robotic vision software.

Here's how I hoped it works...

Processing accesses a text file that includes a string array of data in multiples of 12 numbers - each set of 12 providing data for each object identified by Roborealm - the length of this string is variable depending on how many objects the vision software identifies

At setup (), 20 'Circle' objects are created to place data in. 

A Timer class creates a loop every 6400 ms.

In draw(), at the end of the timer loop, data from the file is added to the Circles objects, to then be used to create imagery and sound

Problem -

I keep getting The constructor 'Timer' is unidentified, with reference to the line in setup () , timer = new Timer(6400)

What am I doing wrong?

As far as I can tell the Timer class seems to be constructed properly?

Please help!

Here is the code

Circles [] circles;
Timer timer;
String numbers= join(loadStrings("test2.txt")," ");//loads in file and joins strings into one
int[] nums = int(split(numbers, " "));//converts string to integer array


void setup() {
  size (640,480);
  timer = new Timer(6400);//starts a timing loop
  timer.start();
  for (int i = 0; i < 20; i++) {
      //initialise 20 circle objects
      circles [i] = new Circles(0,0,0,0,0,0,0);
    }
} 

void draw() {
background();
if (timer.isfinished());//end of the timer loop
  {
  for (int i = 0; i < (nums[].length/12); i++){ //put data into active objects
    circles[i].Xpos = nums[i*12];
    circles[i].Ypos = nums[i*12+1];
    circles[i].Rad = nums[i*12+2];
    circles[i].Standev = nums[i*12+3];
    circles[i].ColR = nums[i*12+4];
    circles[i].ColG = nums[i*12+5];
    circles[i].ColB = nums[i*12+6];
    }
  for (int i = nums[].length/12; i < 20; i++){//put zero data into inactive objects (see Circles class / deactivate
    circles[i].deactivate;
    }
  timer.start(); //restart the timer
  }
}

//define Circles class
class Circles {
 
  int xpos;
  int ypos;
  int radius;
  int standev; //standard deviation of circle colour;
  int colourr; //mean red colour of circle
  int colourg; // '' green
  int colourb; // '' blue
  Timer timer;
 
  //Circles Constructor
  Circles(int Xpos, int Ypos, int Rad, int Standev, int ColR, int ColG, int ColB)
    {
    xpos = Xpos;
    ypos = Ypos;
    radius = Rad;
    standev = Standev;
    colourr = ColR;
    colourg = ColG;
    colourb = ColB;
  }

  //void display() {
  //to display imagery...
  //}

  //void sound() {
  //to make sound...

  void deactivate() {
    xpos = 0;
    ypos = 0;
    radius = 0;
    standev = 0;
    colourr = 0;
    colourg = 0;
    colourb = 0;}
  }
}


class Timer {
 
  int savedTime; // When Timer started
  int totalTime; // How long Timer should last
  int passedTime;
 
  Timer(int tempTotalTime) {
    totalTime = tempTotalTime;
  }
 
  // Starting the timer
  void start() {
    // When the timer starts it stores the current time in milliseconds.
    savedTime = millis();
  }
 
  // The function isFinished() returns true if 6,400 ms have passed.
  boolean isFinished() {
    // Check how much time has passed
    int passedTime = millis()- savedTime;
    if (passedTime > totalTime) {
      return true;
    } else {
      return false;
