String representing movie image varitable
Oct 21st, 2008, 2:10pm  
import processing.video.*;
Movie OneMovie;
Movie TwoMovie;
String c = "OneMovie";

void setup() {
 size(200, 200);
 String c = "OneMovie";
 OneMovie = new Movie(this, "station.mov");
 TwoMovie = new Movie(this, "CheeziPuffs.mov");
 OneMovie.play();
}

void draw() {

 if (key == 'b') {
   OneMovie.stop();
   c = "twoMovie";
   TwoMovie.play();
   image(c, 0, 0);
 }
 image(c, 0, 0);
}

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


My problem is it tells me to use void image within the void draw, which as we all know, is just one big synax error waiting to happen, why will it not except a string representing, a name, representing a movie clip. TOo many degree's of separation?

Any help appreciated,
cheers.

Unfortunately you can't do what you're trying to do. There's no nice way of referring to variables by strings.

What you could do however is something like:

Code:
import processing.video.*;
Movie[] Movies;
//Movie TwoMovie;
//String c = "OneMovie";
int movieNum;
 
void setup() {
  size(200, 200);
  //String c = "OneMovie";
  Movies=new Movie[2];
  Movies[0] = new Movie(this, "station.mov");
  Movies[1] = new Movie(this, "CheeziPuffs.mov");
  Movies[0].play();
  movieNum=0;
}
 
void draw() {
 
  if (key == 'b') {
    Movies[0].stop();
//    c = "twoMovie";
    movieNum=1;
    Movies[1].play();
    image(Movies[movieNum], 0, 0);
  }
  image(Movise[movieNum], 0, 0);
}
 
void movieEvent(Movie m) {
  m.read();
}
