EDIT:

Thanks guys, got it! appears that the explode() function was called from the old object, rather then it’s new clone! 🙂


I have a hashtable of such objects

class BodyDataObj implements Cloneable {

  World world;
  Body body;

  protected BodyDataObj clone() throws CloneNotSupportedException {
    return (BodyDataObj) super.clone();
  }

}

when needed, I make a clone of a needed object from the hashtable

BodyDataObj bodyDataMaster = bdoTable.get(name);
BodyDataObj bodyData = null;

try {
  bodyData = (BodyDataObj) bodyDataMaster.clone();
} catch (CloneNotSupportedException e) { 
  // Handle error
}

bodyData.world = world;
bodyData.body = body;

and pass the world and body objects to my already cloned bodyData object.

Yet when I try to access this world and body object from within the BodyDataObj object, I get a NullPointException, as if they are cloned blanks.

Any ideas how to fix that?

Thanks!

    From the answer to the comment the answer seems to be this:

    b.getWorldCenter() returns null.
