hover over prim floor

Hi, I am having a really frustrating time getting a vehicle script to work. It hovers fine over terrain, but isn't hovering over prim floors. What vehicle type and flags do I need to set for this to work?

I assume it will "touch" the floor and rest on it?

The solution seems simple.. include an invisible prim on the bottom of the vehicle. a "bumper" to keep it always above the surface below it. Then lose your "hover over land" code.

A supplemental answer is that the vehicle tweaks to the physics engine don't handle things like prim roads when it comes to hover height. Put another way, there are no flags that let you hover over prims with the same high level of abstraction used with hover ground or water or global. So, the short answer is you're screwed, except that Winter's suggestion is perfectly valid.

Dammit, I was starting to suspect that hovering no longer works over prims, but was assuming I was just doing something wrong since I've never scripted a vehicle before. Is this something LL is planning to fix or are hover vehicles simply no-go anymore?

We might possibly see some additional vehicle functions, seeing as how new roads are being built, but quite honestly I wouldn't make any plans based on it. Development priorities appear to have moved quite squarely away from physics-related functions towards those relating to communication and land management.

The new LSL for detecting parcel prim limits will be handy for automatic vehicles though.

As well as the ideas above, you could (if you were feeling really ambitious) create a flying vehicle that automatically set an appropriate target altitude for itself, based on using a sensor to find objects below and in front of it at an angle depending on its velocity perhaps, or the ground if it couldn't find any objects. Or it could fire a scan projectile out which would feed back the location where it hit something, and set the target height based on that. It would have to have an automatic "move to height" system in the script as well since you wouldn't be using the built-in hover system. Not exactly the simplest of solutions, that, I'm afraid.
