I am new to processing and recently working on a project. In my project I want to play a movie based on the occurrence of the motion. So I simply find the average motion and based on that I play the movie.

But the problem is that , a movie plays just for once. As I know draw() function continue sly run. 

when the program run first time and I create a movement , then movie plays and continues till its end. but after that 

  next time when I again make a movement then a movie doesn't start.  why???

Any Suggestions...???
