Change to video 2 if "key pressed".

FilipeHenriques

Hello, so I have the code that follows next, what I pretend is to create a rule where if I press the key "2" it will play the video number 2 , but I don't know how to get it. I have all the videos in the same folder. The names are : video1.mp4 , video2.mp4...etc . I need a rule where I play video 2 by pressing key number 2. Please help me.

Code :

import processing.video.*;

Movie theMov; 
boolean isPlaying;
boolean isLooping;


void setup() { 
  size(600, 300);

  theMov = new Movie(this, "C:/Users/Filipe/Documents/Processing/libraries/video/video1.mp4");
  theMov.loop();  //plays the movie over and over
  isPlaying = true;
  isLooping = true;


}

void draw() { 
  background(0);
  image(theMov, mouseX-theMov.width/2, mouseY-theMov.height/4);
} 

void movieEvent(Movie m) { 
  m.read(); 
} 

void keyPressed() {
  if (key == 'p') {
    // toggle pausing
    if (isPlaying) {
      theMov.pause();
    } else {
      theMov.play();
    }
    isPlaying = !isPlaying;

  } else if (key == 'l') {
    // toggle looping
    if (isLooping) {
      theMov.noLoop();
    } else {
      theMov.loop();
    }
    isLooping = !isLooping;

  } else if (key == 's') {
    // stop playing
    theMov.stop();
    isPlaying = false;

  } else if (key == 'j') {
    // jump to a random time
    theMov.jump(random(theMov.duration()));

  }
}

You have enough sample code handy to be able to accomplish this yourself. I think what you are really missing is an understand of the process that should occur. So let's come up with a plan first.

What should happen before the sketch even starts?

• You should load the first video.

• You should load the second video.

• You should remember that the first video is the one that will be playing first.

• You should start the first video playing.

What happens when the sketch is redrawn?

• You should draw a frame of the movie that is playing. You will know which movie to play because you have remembered which one is playing.

What happens when a key is pressed?

• If the first movie is playing and the key pressed was 2, then...

• ... stop playing the first movie.

• ... start playing the second movie.

• ... and remember that second movie is now the one that is playing.

I would suggest that you write a new sketch that does only the above. Use the existing sketch you have as reference - do NOT try to change it!

Once you have attempted the above steps, post the code of your attempt here for more help.
