I'm working on the DM for the Ju88 (version 1 is available at simFiles and my site), and I've decided to add aileron damage. I've managed to make the ailerons detach when shot at, but the plane still moves like it's undamaged! There must be some other values I'm not changing. I've noticed that the aileron is a child of the wingtip itself on the Ju88, so would I need to make some changes to the wingtip properties too? What part or DOF (or airfoil?) should be disabled when the ailerons detach to stop the plane from rolling when joystick input is made?

Thanks

Hmmm. It's complex, to say the least, but the airplanes that have a working example of control surface damage are the P-51D beta version (do a search on the forum and you'll dredge up the link), the Fokker DVII, and the Aussie Spitfires (available here: http://sites.netscape.net/jeditaub/Downloads )

Download one of these and dissect it in OPS to see how it works. Basically it involves adding an "invisible" wingtip with the aileron properties, removing the aileron properties from the "real" wingtip, and then detaching the invisible wingtip at some damage level. The aileron's "aerodynamic properties" are contained in the wingtip itself, not the aileron. The aileron object is just for visual effect. Likewise, the elevator and rudder don't really "do anything," the control surface is contained in the vertical and horizontal stab properties.

Would it be possible then to remove all the aileron data from the wingtip and place it in the aileron itself? Then, all that would need to be done upon damage is remove the aileron, and the aerodynamics would be removed too. Would that work?

I'll check out those planes you mentioned though, thanks for the links and info.

Cheers,

There's also a way to activate/deactivate airfoils in mid-air that I came up with. (bloody amazing it works too!) Do a search for that. It saves you the bit of making a hidden wing tip that interfers with the AI buisness. If you want, I can send you the test models that I did this with. One has it where you press a key to activate/deactivate the airfoil, and on the other one, the airfoil is activated when a certain damage level has ben reached on the wingtip.

ArgonV,

The airfoil activation/deactivation thing you mentioned is interesting, especially the method where airfoils can be activated/deactivated upon reaching certain damage levels. It'll be a great help if you would send me those test models.

Thanks

Sent. If you have any questions as to how or why it works, please ask!

On this old subject, after further testing done a few weeks back on the A10, I have concluded that there is something in my airfoil damage that works, I've had my right wing tip shot up and found it pretty damn hard to control, to make sure it was due to damage I jumped into an A10 that hadn't been in action yet and it flew perfect, so, I can't tell you whats working in my damage model, but something is, and it has the added advantage that enemy AI still attack you when your badly damaged. Just wish I knew which property was giving me this effect, cause it's really rather good

Nat,

Is that DM you described for your A10 existant in the A10 Beta which we download?

Maybe I can take a look at it. Whatever it is, all the properties for the effect you're describing should be in the right wingtip part.

Harman, yes it's all in the A10 Beta (not very beta really, finished other than touch ups) each wing part has a DM that alters (or tries to) the current airfoil data for that wing piece at different damage levels, I honestly don't know which alterations worked, I put a few in there to see what happend, and with damage I do know that it gets harder to fly, the trick is isolating which alterations I made are actually working, if that can be found out it would be perfect for this type of damage modeling cause then you can easily add progresive damge to wings/airfoils, good luck finding what works, I've not dug into it myself like I should have.
