Videos triggered by color tracking?

edited February 2016 in Library Questions

EDIT TO PREVIOUS QUESTION: Alright so I've sort of found answer to my previous question, but now a new one has been brought up. First off, I am in no way familiar with coding. I'm just an artist desperately trying to get an installation piece prepared for a show. I'm very sorry that my code is probably an inelegant hodge-podge. Secondly I'm using Processing 2.2.1.

For this project, I have Processing create two windows. In one window, it searches all the colors found in a webcam display for certain colors.

Based on whether it finds the specific colors, different videos will play in the second window. (For instance, if the webcam sees the color red, the video Rune1 will play in the second window).

Now I've gotten the code to work before, but it just layers the videos on top of one another. What I want is to try to have the videos switch out instead (One video stops playing when another starts). I've tried some code I found in the forums, but I'm such a newbie and my code is so convoluted that I can't get it to work. Would anyone be willing to take a look at this mess?

Code:

    I edited some of the code so it's running BUT instead of switching videos from Video 1 to Video 2 back to Video 1 depending on the color change, it sticks on Video 2 and will not change to anything else. Any suggestions?

  • koogskoogs 
    if (worldRecord1 < 20) {
  VideoPlaying = 1 ;
  println(VideoPlaying);
}

if (worldRecord2 < 20) {
  VideoPlaying = 2 ;
  println(VideoPlaying);
}

    }

    can both these conditions be true at the same time?
