> I have tried using this code but the code I put in 4 videos but the video only plays the first video as if other videos are playing after the first video. Is there a way to solve it?

```auto

  //Fim videos

void draw() { 

  toogle();
  if (Vid1) {

    println("video1");

Hello @Player,

I trimmed down your code for testing the logic:

```auto
int VideoPlaying;

boolean Vid1 = false;
boolean Vid2 = false;
boolean Vid3 = false;
boolean Vid4 = false;

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

void draw() { 

  //This is executing 60 times a second!
  //toogle();
  
  //if (Vid1) println("video1");
  //if (Vid2) println("video2");
  //if (Vid3) println("video3");
  //if (Vid4) println("video3");
}

void keyPressed() {

  //video
  if (key == '1') {
    VideoPlaying = 1 ;
    println(VideoPlaying);
  }

  if (key == '2') {
    VideoPlaying = 2 ;
    println(VideoPlaying);
  }

  if (key == '3') {
    VideoPlaying = 3 ;
    println(VideoPlaying);
  }

  if (key == '4') {
    VideoPlaying = 4 ;
    println(VideoPlaying);
  }

}

void toogle() {

  if (VideoPlaying == 1) {
    Vid1 = true;
    Vid2 = false;
    Vid3 = false;
    Vid4 = false;
  }

  if (VideoPlaying == 2) {
    Vid1 = false;
    Vid2 = true;
    Vid3 = false;
    Vid4 = false;
  }

  if (VideoPlaying == 3) {
    Vid1 = false;
    Vid2 = false;
    Vid3 = true;
    Vid4 = false;
  }

  if (VideoPlaying == 4) {
    Vid1 = false;
    Vid2 = false;
    Vid3 = false;
    Vid4 = true;
  }
}

```

Read the comments!

Try putting the code in _draw()_ into _keyPressed()_ so it only executes once and see what happens.

This was not tested with video.
