Using existing Godot demos for testing

[Saitodepaula]

Are there any chance that you could use some existing demos for Godot to test Godot-Jolt?

May I suggest my own demo? It's a physics based vehicle using only 6DOF joints.

In my demo's github page, I also list other vehicle implementations (using other methods) and issues with Bullet and Godot Physics. So it could be a nice source of material for testing.

I know it sounds like I'm lazy and just want you to do the hard work for me, but since my demo has more than 50 stars on github, I think there is some interest in it.

Also, since my demo uses many of the 6DOF features, it can be a good test I think.

Another point: the vehicles have different behaviour with different physics FPS, so it could be yet another type of test to the physics engine.

Yes, the existing examples are a bit lackluster. The long-term plan was to port over Jolt's own samples to the examples project, mostly as a sanity check. These include a constraint-based vehicle, similar to your own I guess, as well as some ray-cast vehicles. The ray-cast vehicles do however use a specific VehicleConstraint in Jolt that probably won't be exposed in the first phase of this project, but Godot's own VehicleBody3D might suffice there.

As far as including existing Godot demos, I've also been contemplating making use of the official physics tests in some way, and maybe some other demo project there. I guess the "Truck Town" demo would be an interesting test for the VehicleBody3D node type, even if it's a bit rough around the edges.

All that is to say that improving the examples/demos is on my list of things to do, as well adding some kind of functional tests, but probably for when the extension is a bit more stable. And while I might not use your specific demo directly, there will most likely be some kind of constraint vehicle and ray-cast vehicle in there.
