Stop clicks with Area2d?

[rich willow]

Trying to make some simple point and click mechanics, and I need some interactable (clickable) objects. I made them out of a simple Sprite2D with an Area2D and CollisionShape2D.

The character movement uses unhandled_input to check the clicked spot and physics_process to actually update it if it can (i.e. not clicking a UI element).

What I can't quite figure out is if there's a way to essentailly stop clicks with an area2d input signal in the same way a UI element can. I know I could try and convert all interactable objects into Control nodes, but that makes it harder to do certain things with the objects too, so I'm not sure I want to do that. Also it would be tedious.

My first thought was to use set_input_as_handled on click event but it seems that won't work because the priority isn't actually higher than unhandled_input (or something like that? All I know is it doesn't work. Is it just a timing thing?). I also tried putting get_viewport().physics_object_picking_first_only = true and get_viewport().physics_object_picking_sort = true in the ready function of the interactables and raised the Z index but still no luck. So I'm not quite sure what I need to do.

Area "input_event" runs after unhandled input, because it counts as Physics Picking Event, if i am correct, so that won't work. I would suggest either trying to detect if an area was clicked in your character and discard it there, or you can try to use _input() func in your area, but you will have to check if it is inside the area manually, cause this one checks the entire viewport for input events.

Not sure if it's best solution, but that should work: ```func _unhandled_input(event: InputEvent) -> void:
if event is InputEventMouseButton and event.button_index == MOUSE_BUTTON_LEFT:
if event.is_pressed() and is_valid_move():
print("Clicked ground or smth")

func is_valid_move() -> bool:
var para = PhysicsPointQueryParameters2D.new()
para.position = get_global_mouse_position()
para.collide_with_areas = true

var result = get_world_2d().direct_space_state.intersect_point(para)
print(result)

return result.size() == 0 ```

Oh, that does work. Thank you so much!

func _ready() -> void:
get_viewport().physics_object_picking_sort = true
get_viewport().physics_object_picking_first_only = true

I think this only works when you use:
func _input_event(_viewport: Viewport, event: InputEvent, _shape_idx: int) -> void.

not unhandled input. This is recommended for Area2D mouse inputs.
This should work.

I originally had the code in _input_event, but I moved it to _unhandled_input so that I could block clicks on UI too. I have also now changed things around so that it uses the navigation mesh and navigation agent to make some things a bit easier.

But thank you for the input. I don't know a whole lot about the innerworkings of Godot, so why those work with _input_event and not _unhandled_input was a little lost on me. It's a good thing to know.
