I want to make a video play when someone walks past

Other Hardware Sensors
21

No I don't sorry, rather new to this. The library was from here - http://gsvideo.sourceforge.net/ it was suggested so that I could see the footage of the video. Thanks for you help, it is now connected to the arduino port. Now I just need to figure out how to make the video only play when someone walks past the IR Sensor instead of just on a loop. I really do appreciate your help!

As I said before change this:-

 if(xpos > 190){
    image(movie,0,0,width, height);
  }else background(0);

to:-

 if(xpos > 190){
    image(movie,0,0,width, height);
    xpos = 0;
  }else background(0);

Thanks, I changed your code but it still didn't work. I managed to catch up with the person who first helped me with the code and he came up with this code which now works as a pushbutton so on wednesday we hope to figure out how to do it as an IR Sensor.

//Processing sketch to run with this example:

import codeanticode.gsvideo.*;

GSMovie movie;
import processing.serial.*;

int bgcolor;			     // Background color
int fgcolor;			     // Fill color
Serial myPort;                       // The serial port
int[] serialInArray = new int[3];    // Where we'll put what we receive
int serialCount = 0;                 // A count of how many bytes we receive
int xpos, ypos = 0;		             // Starting position of the ball
boolean firstContact = false;        // Whether we've heard from the microcontroller
long movLength = 0;
void setup() {
  size(640, 480);  // Stage size
  noStroke();      // No border on the next thing drawn
  movie = new GSMovie(this, "MajorProjectVid.mov");
  // Set the starting position of the ball (middle of the stage)
  xpos = width/2;
  ypos = height/2;

  // Print a list of the serial ports, for debugging purposes:
  println(Serial.list());

  // I know that the first port in the serial list on my mac
  // is always my  FTDI adaptor, so I open Serial.list()[0].
  // On Windows machines, this generally opens COM1.
  // Open whatever port is the one you're using.
  String portName = Serial.list()[0];
  myPort = new Serial(this, portName, 9600);
}

void movieEvent(GSMovie movie) {
  movie.read();
}

void draw() {
  movLength = movie.frame(); // 1758 total frames
  println(movLength);
  if (fgcolor > 120) { 
    movie.play();
  }
  else { 
    background(0);
  }
  image(movie, 0, 0, width, height);
  if (movie.frame() == 1757.0) {
    movie.goToBeginning();
    movie.pause();
  }
}

void serialEvent(Serial myPort) {
  // read a byte from the serial port:
  int inByte = myPort.read();
  // if this is the first byte received, and it's an A,
  // clear the serial buffer and note that you've
  // had first contact from the microcontroller. 
  // Otherwise, add the incoming byte to the array:
  if (firstContact == false) {
    if (inByte == 'A') { 
      myPort.clear();          // clear the serial port buffer
      firstContact = true;     // you've had first contact from the microcontroller
      myPort.write('A');       // ask for more
    }
  } 
  else {
    // Add the latest byte from the serial port to array:
    serialInArray[serialCount] = inByte;
    serialCount++;

    // If we have 3 bytes:
    if (serialCount > 2 ) {
      xpos = serialInArray[0];
      ypos = serialInArray[1];
      fgcolor = serialInArray[2];

      // print the values (for debugging purposes only):
      //  println(xpos + "\t" + ypos + "\t" + fgcolor);

      // Send a capital A to request new sensor readings:
      myPort.write('A');
      // Reset serialCount:
      serialCount = 0;
    }
