A Little Research on Vehicle Damage from Restarts

[fpstrollywood 5]

Our server recently added Ghosthawks to the traders. I bought one and stored it on my base to test it out. I was aware of the problem with overlapping geometry of base components so I made sure there were no overlapping floors that it was parked on. When the server restarted it still blew up.

I know that Ghosthawks have problems partly due to having such a low ground clearance. But I think there is a little more to it than that. I also realize that Arma was never designed to have vehicles that persist through server restarts. I have personally seen all kinds of vehicles parked in our safe zone jump as high as 15-20 feet after a restart. I went over to our test server, which is available for use upon request (including limited infistar access) to test building designs and whatnot, and bought a bunch of ghosthawks and started building. 

I built simple structures and stored 8 Ghosthawks on them. Then waited about 10 minutes and restarted the server (repeated multiple times). These were my results:

Before any server restarts

After the first restart, both of these exploded helicopters appeared to have sunk into the flooring a little bit.

After the second restart, even though the tail of this heli had sunk into the flooring after the first restart, it survived the second restart without issue (still sunk into flooring).

After the third restart,

As you can see, there were no issues after the first restart. I have no idea why that is, I even tried getting in and flying around a couple of them between the second and third restarts. 

Hopefully somebody finds this useful. If anyone wishes to conduct similar testing on our test server, just message me and I can send you the info.

thank you for your time and effort.  it is nice to seem some actually test theories out and provide proof of such!

so you know, this 'appears' to happen to little birds parked on wood as well.  i have 2 helis, 1 LB and 1 mohawk.  MH NEVER explodes, LB's do every now and then...???

 

thanks!

In my experience, Hummingbirds have to be parked on a SINGLE FLOOR TILE. After coming to that conclusion, mine have lasted me for a long time.

As far as I noticed - heli will be fine until the wheels are on the floor. But if at least one wheel will be on a joint, between floors - there will be BOOM. Sometimes insta-boom. We followed this rule and it seems to work.

Well I tested these helis with each wheel touching a single floor piece, none of them had wheels touching joints of the floor panels. I even left a gap where the large part of the "belly" of the helicopter was for one.

I have the same with all vehicles. If they are too close to each other, on the restart when they spawn thay are jumping and blowing up.

Interesting piece of information there
