this reference within custom class
Apr 16th, 2008, 10:39pm  
Sorry if this has been answered, I can't seem to find it by searching the forums.

Certain classes (processing.video.Movie in my case) take the current PApplet as the first argument. If I've created a custom class, and I'm loading a movie within that, 'this' refers to my class, not the PApplet.

I tried setting "parent" outside my class and using that:
PApplet parent = this;
but my video isn't loading, and I'm pretty sure this is the issue (it works just fine with the same video in the demo video sketch)

What is the correct way to set the PApplet reference?

thx

You need to pass a PApplet object into your class, for it to then pass into MoveiMaker, so for example:

Code:

class myClass
{
  PApplet parent;
  MovieMaker m;

  myClass(PApplet p)
  {
    parent=p;
    m=new MovieMaker(parent,.......);
  }


}
