I'm scanning the API's but not coming across any nice booleans :/

How do you check if an object is currently added to the world?
It worked - here's the code if anyone's interested:
(anActor is the actor you're checking)
public boolean isInWorld(Actor anActor)
{
for(int i = 0; i < getWorld().getObjects(null).size(); i++)
{
if(anActor.equals(getWorld().getObjects(null).get(0))) return true;
}
return false;
}
Err, that doesn't work. :)
Maybe this would work:
(Notice I get(i) rather than get(0), and use '==' to compare which is ok - and faster - in this case, although .equals() also works).
However if that works it's really only by chance - there's no guarantee that getObjects(...) returns a list in the same order each time you call it. So, even better would be:
But, there's a much simpler and faster way, which is:
Or, if you're worried about the possibility that the actor may be in a different world, you can use:
public boolean isInWorld(Actor anActor)
{
for(int i = 0; i < getWorld().getObjects(null).size(); i++)
{
if(anActor == getWorld().getObjects(null).get(i)) return true;
}
return false;
}public boolean isInWorld(Actor anActor)
{
List l = getWorld().getObjects(null);
for(int i = 0; i < l.size(); i++)
{
if(anActor == l.get(i)) return true;
}
return false;
}public boolean isInWorld(Actor anActor)
{
return anActor.getWorld() != null;
}
public boolean isInWorld(Actor anActor)
{
return anActor.getWorld() == getWorld();
}
I meant get(i) >.< and I generally do save it to a list, was just in a hurry though, and didn't realise that it changes the order. Thanks :)
No problem.
By the way you can also do:
... however the way I showed you before is the best way.
There are lots of ways to accomplish the same thing :)
public boolean isInWorld(Actor anActor)
{
return getWorld().getObjects(null).contains(anActor);
