[Fix] Colliding with the A330-MRTT AI tanker cause "crashes"

[Johan G]

I have often been frustrated about that I sometimes crash into the A330-MRTT AI tanker when I am practicing air-to-air refueling.

Considering that it is difficult enough without it, and that you can not crash by colliding with multiplayer aircraft this should change.

I used to reset FlightGear afterwards, but recently I found the property "/sim/crashed" (bool) which can be set to "false" through the property browser. Though I would still have to fly ahead to the tanker and join again.

I have traced this down to that only the drogue and hose have the <enable-hot> animation set to "false"; the rest of the aircraft implicitly is set to "true" and touching those objects will "crash" FlightGear (as in set "/sim/crashed" to "true" thus freezing the simulation).


Adding the following should fix it (seem to work for me):

To fgdata/AI/Aircraft/A330-MRTT/Models/A330-MRTT.xml:

Code: Select all

  <animation>
    <object-name>Cylinder.006</object-name>

    <object-name>fuselage</object-name>
    <object-name>ailes</object-name>
    <object-name>ailes2</object-name>
    <object-name>derive</object-name>
    <object-name>moteurs</object-name>
    <object-name>repports</object-name>
    <object-name>supports</object-name>
    <object-name>echappes</object-name>

    <object-name>trous</object-name>
    <object-name>perche1</object-name>
    <object-name>perche2</object-name>
   
    <object-name>vitres</object-name>
    <enable-hot>false</enable-hot>
  </animation>


To fgdata/AI/Aircraft/A330-MRTT/Models/refueling/probe.xml ("refueling-drogue" is already there):

Code: Select all

  <animation>
    <object-name>pod-left</object-name>
    <object-name>pod-right</object-name>
    <object-name>refueling-drogue</object-name>
    <enable-hot>false</enable-hot>
  </animation>


To fgdata/AI/Aircraft/A330-MRTT/Models/refueling/refueling.xml ("refueling-drogue" is already there):

Code: Select all

  <animation>
    <object-name>pod-left</object-name>
    <object-name>pod-right</object-name>
    <object-name>refueling-drogue</object-name>
    <enable-hot>false</enable-hot>
  </animation>

I think you could set the whole thing to uncollidable by just adding

Code: Select all

  <animation>
    <enable-hot>false</enable-hot>
  </animation>


in the top-level file (fgdata/AI/Aircraft/A330-MRTT/Models/A330-MRTT.xml?).

Animations without <object-name> applies to the whole XML file they are in.

Thanks! That was a neat way to do it. Testing it, it worked exactly as explained. Thanks again.

Now, which place would be most effective to ask for it to be fixed before next release: Here, the developer list or the issue tracker?

The developer list or perhaps the issue tracker. A request here is less likely to find its recipient.

Sent off a mail to the developer list, though without first registering to it. It is now awaiting moderation. Subject line is "Fix for crashing into the A330-MRTT AI tanker".

hum.... And of course no one takes the time to check who the author of this model? Yet I have left a Readme.txt in with my email address in the "A330-MRTT" folder.

A simple email to this address with your changes and I'll update almost immediatly

P.S. And yes sorry, but the A330 MRTT, is one of my creations (especially created for the Mirage 2000-5)

Ah. I should have known better. My apologies.

Edit: I notice Torsten Dreyer already applied a change, commit e74da4, but I take the blame for that, as I should have looked for the maintainer.

I don't really see what was bad with the A330-MRTT, except that you need to adjust your speed to never collide the plane , iirc all the refueling models are solid, except for the refueling parts, so yes if you collide, you're dead, as in real flight but this has never been a real problem.
for the mp planes it's a bit different, as they can surge / stop depending lag and jitter values, and once we tried to make them solid, and the refuelings were very dangerous
Now that the whole plane is non solid, i wont ask for a revert, but i just find it was a bit more interesting to have a collision risk when refueling

Looking at the model xml files you might be right.

Caveat: Have not tried ramming them in flight yet though.

Before looking into any of the tankers I expected them all to behave just any multiplayer aircraft.
