child --> parent

Hello
I'm using this code to retrieve current position of Object in world
--- Code: --- private SimpleVector getParentTrans(Object3D model)
{
Object3D[] parents = model.getParents();
SimpleVector sv=new SimpleVector();
for (int i = 0; i < parents.length; i++) {
if (parents[i] != null) {
sv.add(parents[i].getTranslation());
sv.add(getParentTrans(parents[i]));
}
}
return sv;
}
public SimpleVector getCurrPosition()
{
SimpleVector sv = model.getOrigin();
sv.add(model.getTranslation());
SimpleVector par = getParentTrans(model);
System.out.println("PAR: "+par);
sv.add(par);
return sv;
}
--- End code ---
it looks like it works fine!!!
But when I unlink child from parent it look like it is not removed from array which is returned by method Object3D.getParents(). Is that a bug, or i made a mistake??
Regards
EgonOlsen:
A little bit both. It's described that way (albeit not very cleary, i have to admit) in the docs but it makes no sense, does it? So i've uploaded a version that should only return the actually used parents here: http://www.jpct.net/download/beta/jpct.jar
Hope this helps.

I found a workaround, and now i translate objects seperatlly.
Thanks 4 help!

Hello again.
Should above code work also when objects are rotated?
I'm thinking of going back to my previus child-->parent translations.

I'm pretty shure it doesn't
Is it possible to get an absolute position of child object in world.
