cannot create GLMovie object within class

edited November 2016 in Raspberry PI

hi all, i get an error when creating a GLMovie object within a class like:

class Film {

  GLMovie vid;
  String filename;

  Film(String tempFilename) {    
    filename = tempFilename;

    vid = new GLMovie(this,filename); //error: 
    //The constructor "GLMovie(Film,String)" does not exist

also the use of "this" is not clear to me ...

thanks:) ps: the formatting looks a bit strange here!? sorry for that

    (highlight code, press ctrl-o. i've done that for you)

    this is probably meant to be PApplet. but if you move the call into a class then this becomes the class, which is probably why it isn't working.

    you need to pass the PApplet into you class, as another argument in your Film constructor.

    All loading resources should go to setup(). Then you can pass the already loaded resource to your classes' constructor:

    // cannot-create-glmovie-object-within-class#Item_2
    // 2016-Nov-20
    import gohai.glvideo.GLMovie;
    Film film;
    static final String MOVIE_FILE = "";
    void settings() {
      film = new Film(new GLMovie(this, MOVIE_FILE), 0, 0);
      while (film.vid.height == 0)  delay(5);
      size(film.vid.width, film.vid.height);
    void draw() {
    class Film {
      final GLMovie vid;
      final int x, y;
      Film(GLMovie mov, int xx, int yy) {
        (vid = mov).loop();
        x = xx;
        y = yy;
      void display() {
        set(x, y, vid);
