Add VehicleWing3D node for wing physics simulation

[wmigor]

Describe the project you are working on

I'm making a game where you can drive cars and fly planes.

Describe the problem or limitation you are having in your project

Godot lacks built-in wing physics

Describe the feature / enhancement and how it helps to overcome the problem or limitation

Implementing wing physics in the engine would simplify aircraft game development, likely resulting in more flight-based games.

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

I’ve already opened a PR with the code: godotengine/godot#106571
Demo PR: godotengine/godot-demo-projects#1206

If this enhancement will not be used often, can it be worked around with a few lines of script?

This cannot be implemented with just a few script lines. In the script it will work slowly

Is there a reason why this should be core and not an add-on in the asset library?

Aircraft mechanics are inherently exciting. If this is implemented in core, people will be able to easily create airplane games right out of the box, just like they can with VehicleWheel3D for cars.

It's great, but too specific feature.
Godot, as I can see, keeps the core quite simple and even doesn't have built-in terrain or FPS/TPS controllers.
So, wing physics as addon will be more suitable.

Similar aircraft physics for Unity (for reference)

I agree, except that there is Vehicle Physics, so the same could be said for them.

I'd argue vehicle physics should move to an addon actually

You can open a proposal for that

[wmigor]

Ок. I'll convert it to addon

[Zireael07]

@leandro-benedet-garcia There's actually an issue/proposal for vehicle physics being moved to addon already, somewhere - it's been noted like 3 years ago but no one actually did it

@Zireael07 Can you provide a link to this? I would support such a proposal for the next compatibility breakage.

Also, I want to note in this proposal what I've already noted in the engine PR. I have been developing a general-purpose vehicle specification in glTF and as a Godot addon. You can find the glTF extension specs for the OMI vehicle extensions here, and you can find the Godot implementation here. Right now it includes vehicle bodies, wheels, thrusters, and hover thrusters, but no wings.

It would be great to add wings to this addon and as a glTF extension, allowing for engine-agnostic aircraft models. Imagine if you could build an aircraft in Blender or something, and export it to Godot, Unity, Unreal, or any other game engine, and have it just work out of the box, as long as the engine implements an importer for this data.

Huh, I thought it was in the proposals repo but either my search-fu sucks or it was never there.

The closest I can find is godotengine/godot#19486 (comment)

[wmigor]

I started making the addon https://github.com/wmigor/godot-aircraft

Will it be possible to use a C++ addon in omi-godot?
