Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:
- Tag FS2020 specific questions with the MSFS2020 tag.
- Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
- Questions about aircraft design can be posted in the Aircraft design forum
- Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
- Questions about terrain design can be posted in the FS2020 terrain design forum.
- Questions about SimConnect can be posted in the SimConnect forum.
Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.
By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.
Rolling and pitching AI ships in FSX
- Thread starter spatialpro
- Start date
.

Okay, I've gone the SimConnect method. I'm using PLANE PITCH DEGREES and a cosine wave function to update the pitch of the carrier. I have a timer set to update the pitch every 25 milliseconds. I've used the Event ID's to EVENT_FREEZE_LATITUDE_LONGITUDE and EVENT_FREEZE_ATTITUDE to make sure FSX doesn't try un-pitching the carrier.
So, anyways, things work fine (the deck pitches and all), but I'm getting a REALLY odd issue. Once I land on the deck, I start rolling and/or bouncing. Eventually (usually rather quickly), I either fall off, or fall THROUGH the deck.
Another odd thing is that if I slew above the carrier and press F2 to hold my altitude, I'll either ascend or descend depending on which way the carrier's pitching. When slewing over land/water F2 holds the altitude just fine.
Any ideas?

Hi,
That has nothing to do with simconnect, I think. Must be something inherent to FSX.
Same happens when you try to land for instance with a heli on deck of a vessel with hardened surface. You cannot slew to it and once landed, you have to set your parking brakes if not, you are thrown off each time the vessel makes a turn.

So, is this a showstopper? Is it possible to accurately simulate landing on a rolling/pitching deck? Rolling off the pad should be what happens unless you put on the parking brakes, so that seems fairly realistic. Unless it is overly sensitive, of course - which is what I think the case might be - havent tried.

Robystar: Not sure if we're talking about the same thing, but yeah, I agree that it does have to do with the way FS handles vehicles with hard surfaces.
Misho: Yeah, I'd call it one. I'll move/roll/shunt/jump/fall with or without my brakes, independent of aircraft too (tried both the FA-18 and the trike). I can barely slow down (arresting cable force seems dampened) before I either bolter, or if I do manage to land, before I start moving about the deck.
A few more odd things:
1. When using the pilotable Nimitz (converted to be an "aircraft"), the bouncing/jumping seems to be lessened and the parking brake is capable of holding me in place. Problem is, as I'm pretty sure we all know, when converted to be an aircraft, the meatball, lights and catapults don't work.
2. When using the proper carrier (actual boat), sometimes, when I manage not to immediately bounce or fall though, I can actually roll uphill, then, disappointingly, fall through.
3. Even using a normal carrier (non pitching, AI boat), I've had occasions when I fall through the deck also. At least I think I'm falling through. I could be rolling off, but I think I recall a video clip of me actually just falling through the deck (can't remember the specific video, but it was on YouTube - it happened in multiplayer).
I'll try making a video of this mess of a pitching deck after my good computer decides it'll work again.

Hi Olliyau ( what a diffcult name, I hope I spelled it right?),
No, we are not speaking about the same thing in as far as you are speaking about simconnect and I do not. But I think one could have to do with the other.
What I am saying is that, if you have a moving vessel on a route, made by AIBTC for instance, and you try to land on it, you will not be able to slew to the landing deck nor will you be able to sit still on the deck as long as you have not put your parking brakes on.
Since you are talking about pitching, no, the Living World AI does not pitch or roll. That is where it is different. (But for the time being, and at least for me, it is difficult enough to land a pilotable heli on a movable platform
).
PS Misho, the moving bus did not bob up and down!
PS2 Olliyau, if you are piloting the Nimitz, how can you be on it with a pilotable aircraft at the same time?

Misho: Not to be repetitive, but pretty much what robystar said: the bus is moving, but it isn't pitching. I can "inject" the boat without telling it to pitch and it works fine, just as any other AI carrier (or Loopy Larry bus) would work. I was just saying that I when I do (rarely) fall off the normal carrier, I have a feeling that I'm falling through the deck, but it's more likely that I just have my parking brakes off and my plane creeps forward off the edge.
Robystar: I am pretty sure I was able to slew onto a moving carrier at one point, but haven't tried/tested it recently. I can usually stay pretty still on a carrier with my parking brakes off, but I will usually end up creeping forward and rolling off the edge (not like getting thrown off really quickly or anything). Regarding your PS, I wasn't piloting the pilotable (converted to be an aircraft) Nimitz, I told my SimConnect program to use/drive it instead of the normal (boat) Nimitz. Oh, and feel free to call me Orion.

As Ollyau mentions it, is there a way to increase the friction btn landing gear and deck surface? Even with PB on, helicopters want to slide of the flightdeck whenever the platform makes a turn or increases/decreses speed... Tie downs would be great, could even be modeled into the helicopter, does FSX handle anchors or tie downs?
