Is Vector inside other object/object's bounding box

[Ruthven Ravenhurst]

I have an idea for a game. Objects are placed around a sim/area for avatars to find. Simple enough hunt right? Except these objects will be "alive" and I want them to move around on a timed interval until someone clicks it, which would then tell it to move to a specific location, and be recorded that said clicker found n many of the objects. I've got most of the logic in my head with an idea of how to script it. But I want to make sure the objects won't land inside of another object, making it "impossible" for an avatar to see it. Maybe with llCastRay?

llCastRay can't detect phantom or volume detect objects, so it's not foolproof.

Have you looked at pathfinding?

I didn't even know that was a function. I'm not wanting a constant movement though, well maybe. I'll think about that. But It would definitely be useful for another project I have in mind.

Actually, cast rays can detect phantom objects just fine.  You need to specify  RC_DETECT_PHANTOM among your options, is all.  The real problem, of course, is that if your phantom object is inside another object, the cast ray will detect the other object first.  If you know its UUID, though, you can always get its position with llGetObjectDetails in a fast timer or, less efficiently, with a repeating sensor.

I wonder if I could use llNavigateTo with llCastRay, then update the target position if the previously set one would land inside an object. I'm not looking to detect the position of an object, but make sure the targeted position isn't inside an object

You may be overthinking the problem.  Why not just make yourself a list of a couple dozen preset locations and then flip through them randomly?  You'll know for sure that none of them is inside another object, and you won't have to do any tricky scripting. Choose a new spot from the list and llSetRegionPos.

Oops, I didn't read carefully enough!

I like that better than trying to find a clear spot to park. llCastRay could just barely sneak past an object near the target position, allowing a move that ultimately results in a collision.
