Just to add a little to that - stay-in-a-box mode is selectable on/off from the nimitz-demo file, and the limits of the box are selectable. If you want a ship which has solid decks, add it to the nimitz-demo file as another carrier, and make the path to the 3d model whatever you want it to be. You might be able to constrain the operations box enough for your needs, otherwise it's only a straight course and fixed speed atm, I'm afraid.

Let's see ... **Hi Mathias,* thank you for your explanation! now I understand why it works with a fixed course (no turnings) but not with a flightplan - yet! Let's see is always promising for the future :-) Regards Georg ** Just to add a little to that - stay-in-a-box mode is selectable on/off from the nimitz-demo file, and the limits of the box are selectable.

HTH Vivian ***Hi Vivian,** I'll have a look into that this evening and try to change the operations box limits. If it works with flightplans I'll give feedback. Thank you for the answer anyway, it is a chance! As for a fixed course the solution is quite easier as I found out by experiments. I used a modified version of Eric's freighter and gave it the type carrier and some solid parameter like the carrier has. This works (for a fixed course). Regards Georg ?xml version=1.0?

[Flightgear-devel] AI objects with hardened surface not possible? Dave Culp?
Hi, for my upcoming Bremen scenery I tried to get moving ships which follow the river Weser. There should be at least a hardened hull (deck) to be landable for the BO105. Of course the ship-model is hardened when put into the scenery as a static object. It also works when I make a moving ship-object with fixed direction (see listed XML-file at the bottom of this message). Also creating a flight-plan and let the ship fly at ground-level works very fine and impressive. But I cannot get a hardened and landable surface. May be anyone (Dave Culp?) can answer whether it is possible to create flightplan-models with hardened surface? Thank you for your time and energy.
