Code:

private GameObject GetRandomObject() {
	if (mObjects == null) {
		mObjects = new List<GameObject>(Sims3.Gameplay.Queries.GetObjects<GameObject>(base.Actor.LotCurrent));
		mObjects.Remove(base.Actor);
	}
	return RandomUtil.GetRandomObjectFromList<GameObject>(mObjects);
}

I'm using the above code to select random object from current lot,
but it's a little buggy since plumbbobs and skillmeters are included,
also I want to fix the range of objects to the same floor with the actor..

Is there any way to modify the method to get my desired results?
I've think of two way to do, but it failed or I can't think of how to do.

For selecting objects from the same floor as the actor:
1) Calculate Y-component of position vector by: obj.Y - obj.(height from floor)
and compare this with actor.Y, but even allowing an epsilon for error doesn't work,

2) Test if the route is routable before I really route to the object,
I've no idea how I could do this, and seems there's no relevant method...
or did I overlooked something?

And for not selecting plumbbobs and skill meter:

Code:

foreach (GameObject obj in mObjects) {
	if (obj is Plumbbob || obj is SkillMeter)
		mObjects.Remove(obj);
}

But unfortunately, this just remove EVERYTHING in mObjects

That will actually throw an exception. You can't alter a collection while you're iterating through it with a foreach loop. Use a while loop instead.

Or use FindAll and a Predicate:

(new List<GameObject>(Sims3.Gameplay.Queries.GetObjects<GameObject>(base.Actor.LotCurrent))).FindAll(obj => !(obj is PlumbBob) && !(obj is SkillMeter));

	Nothing's real. Nothing's unreal either. The frontier between true and untrue is a shady fuzzy line. Destiny, or maybe the long flight's time-span, shall decide the issue.

And the problem of getting objects from the same floor is also solved,
getting the value of obj.PositionOnFloor.y would be sufficient
