Found it.

Normally, a caller should * load the model by instantiating SGModelPlacement with the path * to the model or its XML wrapper, then assign any relevant * property node pointers. * * @see SGModelPlacement * @see FGModelMgr#add_instance */ On 6/17/05, Erik Hofman <[EMAIL PROTECTED]> wrote: > Drew wrote: > > Is there an existing interface to allow non-ownship objects to be > > positioned using the propery system?

Re: [Flightgear-devel] AI for Ground Units
Right, that's exactly what I mean. I actually want to control certain ground items via a network interface. Dave suggested looking at the multiplayer model, which I'm about to do.

I just read the documentation on AI models, and it doesn't seem like any of the AI types tie models to properties. I suppose you mean "properties to control the craft"? No, that's not what the AIModel code was designed for, it supplies some properties themselves, mostly for debugging and n=animation but also for updating RADAR info.

It's an AI acenario file for my OV-10 simulator that puts about 45 AI objects around the Ramstein area. Some of the AI objects are static, four tanks and about 12 city signs. You'll need the CVS version of FlightGear to invoke these static objects, or you can make static objects out of "ships" if you have an earlier version. > I just read the documentation on AI models, and it doesn't seem like > any of the AI types tie models to properties. I'm not sure what your question is.

Re: [Flightgear-devel] AI for Ground Units
Is there an existing interface to allow non-ownship objects to be positioned using the propery system? If there's an easy way to specify lat, long, alt, roll, pitch, and heading, that would be really helpful. I just read the documentation on AI models, and it doesn't seem like any of the AI types tie models to properties.

The problem with moving ground vehicles is that they have to know where the ground is at all times, which is not an easy thing in FlightGear. The calculations are CPU-intensive. These calculations are already in David Luff's AI Traffic code, and it was partially adapted to the AIAircraft code by Durk Talsma. Static ground vehicles, or ground vehicles that only move on level surfaces, are a different story. They can be easily modeled using the existing code.

[Flightgear-devel] AI for Ground Units
I noticed in flightgear there are classes for AI aircraft and ships. Has anyone tried to add a car or truck to flightgear yet? Is there any documentation on this? ___ Flightgear-devel mailing list Flightgear-devel@flightgear.org http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d
