function loop??
Mar 18th, 2009, 10:10am  
Hello!

I'm new in Processing and I'm trying to make something.

I've a little program to change around 4 videos by keys.

If you pressed key '1' you play video1, for key '2' video2, etc..

But the problem is that the read of the code is lineal, so you can change from 1 to 2 and later to 3 and later to 4 but you can come back to some video down.

Can you understand me?

I think the problem is that when you read a video is there (in the "draw") so when you "call" to another video down you can't see it because is down.

I would like to know if is possible to work with layers or something similar to say which video must be visible, or something like "unread" the videos...

Can you help me?
Thank you very much! Smiley

I'm not quite sure what approach you're doing but I think you'll want something like:

Code:

//assuming you have objects for each video in variables video1 video2 etc...

int play=1;

void setup()
{
  //load your videos.
  video1.play();
}

void draw()
{
  background(0);
  if(play==1)
    image(video1,0,0);
  if(play==2)
    image(video2,0,0);
  //etc
}

void keyPressed()
{
  if(key=='1' && play!=1)
  {
    play=1;
    video1.play();
    video2.pause();
    video3.pause();
    video4.pause();
  }
  if(key=='2' && play!=2)
  {
    play=2;
    video1.pause();
    video2.play();
    //etc etc
  }
  //etc etc
}

}
}
