How can I use a timer as the source of a variable?

astrugglestudent

Ideally mouseDragged would start a time, and mouseReleased would stop the timer. The number of seconds from the timer would be used to determine the speed of a variable for the LeftEye and Right Eye classes. I've been trying different things with this for awhile now and I keep hitting a wall. Any help is appreciated, thank you.

PImage Face;
PImage Outline;

LeftEye [] LE = new LeftEye[1];
RightEye[] RE = new RightEye[1];
//Timer [] time = new Timer [1];

float tempySpeed;

boolean eyeRoll = false;

void setup() {

  size (500, 650);

  Face = loadImage("Face.png");
  Outline = loadImage("Outline.png");

  for (int i = 0; i < LE.length; i++) {
    LE[i] = new LeftEye();
  }
  for (int i = 0; i < RE.length; i++) {
    RE[i] = new RightEye();
  }
}

void mouseClicked() {

  if (mouseButton == LEFT) {
    eyeRoll = true;
  } else {
    eyeRoll = false;
  }
}

void draw() {

  for (int i = 0; i<LE.length; i ++) {
    LE[i].display();
    if (eyeRoll == true) {   
      LE[i].bounce();
    }
  }

  for (int i = 0; i<RE.length; i++) {
    RE[i].display();
    if (eyeRoll== true) {
      RE[i].bounce();
    }
  }

  Face.resize(400, 650);
  image(Face, 50, 0);
  Outline.resize(400, 650);
  image(Outline, 50, 0);
}

PImage LeftEye;

class LeftEye {

  float ySpeed;
  float yPos;
  float Time;
  float getTime() {
    return(Time);
  }
  Timer [] time = new Timer [1];

  LeftEye() {

    ySpeed = 10;
    yPos = -122;
  }

  void mouseDragged() {
    for (int i = 0; i < time.length; i++) {
      time[i] = new Timer();
      //for (int i = 0; i<time.length; i++) {
      time[i].setTime(1);
    }

    for (int i = 0; i<time.length; i++) {
      time[i].countUp();
    }
  }

  void mouseReleased() {

    for (int i = 0; i<time.length; i++) {
      time[i].duration();
      Time = ySpeed;
    }
  }

  void display() {

    LeftEye = loadImage("Eye.png");
    LeftEye.resize(390, 568);
    image(LeftEye, -17, yPos);
    //image(LeftEye,-17,mouseY-120);
  }

  void bounce() {
    yPos = yPos+ySpeed;
    if (yPos >=255 || yPos<= -122) {
      yPos = -122;
    }
  }
}

PImage RightEye;

class RightEye {

  float ySpeed;
  float yPos;
  float Time;
  float getTime() {
    return(Time);
  }
  Timer [] time = new Timer [1];

  RightEye() {

    ySpeed = 7;
    yPos = -122;
  }

  void display() {

    for (int i = 0; i < time.length; i++) {
      time[i] = new Timer();
    }

    RightEye = loadImage("Eye.png");
    RightEye.resize(390, 568);
    image(RightEye, 139, yPos);
    //image(RightEye,139,mouseY-120);
  }

  void mouseDragged() {
    for (int i = 0; i<time.length; i++) {
      time[i].setTime(1);
    }

    for (int i = 0; i<time.length; i++) {
      time[i].countUp();
    }
  }

  void mouseReleased() {

    for (int i = 0; i<time.length; i++) {
      time[i].duration();
      Time = ySpeed;
    }
  }

  void bounce() {
    yPos = yPos+ySpeed;
    if (yPos >=255 || yPos<= -122) {
      yPos=-122;
    }
  }
}
class Timer {

  float Time;
  float getTime() {
    return(Time);
  }

  void setTime (float set) {
    Time = set;
  }

  void countUp() {
    Time += frameRate*60;
  }


  void duration() {
    getTime();
  }
}

Lots of great timer examples in the forum:

See also Timing Utilities and Countdown Timer under "Utilities" on the libraries page -- looking at examples can be helpful.
