Good day!
I am using Godot 3.2.3stable.official and running into an oddity.
I can replicate it creating a brand new project. I add my top level node as Spatial (3d), add a MeshInstance, give it any shape, add a StaticBody to that, add a CollisionShape to that and add a shape to the collision. I tested with base cube/cylinder etc, some for shape and tried convex/concave colliders and always run into the same thing.
Adding this script to the StaticBody:
extends StaticBody
func _input(event):
if event is InputEventMouseButton:
print("input")
func _input_event(camera, event, click_position, click_normal, shape_idx):
if event is InputEventMouseButton:
print("input event")
func _unhandled_input(event):
if event is InputEventMouseButton:
print("unhandled event")
When I run my code and click on the mesh (or click anywhere for that matter) I get logs from input and unhandled but not from _input_event. I did verify the StaticBody has Input Ray Pickable enabled, which is the default.
I am sure I am doing something wrong, but I don’t see what. Any ideas on things to check?
Thanks!
Have you already read about how the inputs work?

Thank you for the reply!
Yes, I have read over that and have no UI or anything else in my sample app that would be consuming the input, and I do have a camera on the viewport, so theoretically I should get an _input_event on my staticbody from what that link says.
For a bit more context, I downloaded the project from here: https://kidscancode.org/godot_recipes/3d/click_to_move/ which works but was recreating it from scratch. I have two things that are acting odd and I am sure they are related and something I missed but I have clicked on all of the nodes and see no differences in mine versus theirs. I have look at autoload, project settings etc but everything seems the same.
The two differences I see in mine versus theirs in my player (kinematicbody) falls through the ground, so that collision isnt working. I did not alter the collision layers or masks and they look the same as the tutorial. Also, clicking on the ground does not fire _input_event on the attached staticbody. These seem like they are of the same root cause but again, comparing node by node, file by file, settings etc, I see no differences between theirs and mine so I am unsure what I missed.

So I kind of figured this out. I turned on Visible Collision Shapes in the Debug menu and it some things I assumed were magic aren’t. 
The ground has a ConcavePolygonShape, and whilst my editor looks the same as theirs, there is some kind of configuration they must have done. The docs here: https://docs.godotengine.org/en/stable/classes/class_concavepolygonshape.html mention calling set_faces, but since I didnt see anything in their code doing so, the assumption was when you add it to a StaticBody that must happen for you. In their project if I clear the Shape type and then set it to ConcavePolygonShape again, their project is also broken, so it must need to set this somewhere but I haven’t a clue where.
A similar issue is plaguing my KinematicBody, it’s CollisionShape’s shape is a ConvexPolygonShape, which I also assumed would magically get filled in. With this one at least, I can break that guy open in their editor and see where the array was filled in, and if I fill it in by hand, it works.
For both of these, I assume the editor of this version for the Mac isn’t doing something it is supposed to be doing? I don’t see any documentation anywhere that this shouldn’t just work on its own, but I could be expecting too much My next step is going to be to boot into windows and test the same sample project and see if the results are the same.

Same behavior in Windows, so I guess my expectations were just wrong, nothing to see here
