Thanks for reading first.
Specifically, the question posed above is whether pathfinding (or raycasting) can be implemented in godot as in the Unity example. That is, whether you can have a 3D object find a path to any position on any axis and fly to it.
Navigation->NavigationMeshInstance->MeshInstance works really well in fairly flat settings, but not so well when there is no ground for the mesh to span limited polygons.
As shown in the Unity example, I'm looking for a way to move an object to another object - but not a linear movement but a bit smoother and maybe draw the path in the process.
Does this work like this (as shown in the Unity example) at all in godot?
I would also be willing for a donation if I get a simple example project, because the topic is not trivial and apparently not without reason almost nothing useful to godot is to be found on the Internet (apart from 2D pathfinding).
As described, like in the example I would like to be able to move an object from A to B. I like godot but just can't find a way to use it in the 3D setting I need.
