Is llVolumeDetect broken?

It appears that llVolumeDetect, physics on or off, doesn't detect non-physics objects. Apparently the only way to detect non-physics objects is with a non-phantom physics object.

If that's the way it's supposed to be it's a very poor choice IMHO. It makes lots of detection applications pretty much impossible, and I don't see why this would help the sim either. It's already calculating collisions for physics objects with non-physics objects, why does making an object phantom make this harder?

It would be even nicer if there was a way for non-physics objects to detect other non-physics objects.

I'm not very surprised to hear that. Non physics objects don't collide, although physics objects can collide with non-physical ones.

Non-physical objects, even if moved (llSetPos()) etc. don't move, they simply disappear and reappear without moving through the intervening space.

So I'm not sure how you can test for the causing a collision, nor indeed why you'd want to.

Well yes, but physical llVolumeDetect objects don't collide with non-physical ones.

A couple releases ago LL broke llVolumeDetect (breaking Primmies, the Game Dev Contest Winnning Game).

Yeah, it's been messed up since 1.7 (breaking some of my stuff). I've posted to hotline to lindy twice and bug reported.

Heard nothen except, "we will try to get you an answer", months ago.
Then I went to lunch.
