How to call for a method in an intersecting object?

Hi everyone, I want to make a game where you have an object called Ball and an object called Brick, and when the ball hits a brick, a variable called life needs to be lowered by one. This is the code I have right now: 
Actor blok = getOneIntersectingObject(Brick.class);
if (blok != null) {
blok.leven--;
           }

That creates an actor object which doesn't have the life variable in it. There are TWO things you should do:
  • Change the first line to: 
    Brick blok = (Brick) getOneIntersectingObject(Brick.class);
  • Say what your problem first so that I don't have to figure it out.

My problem was that it gave me an error at the blok.leven--; part. it said it couldnt find the variable leven. But I changed the first line and it works perfectly now! Thanks a lot for your help!
