InputEventMouse.global_position doesn't return global position

[razcore-rad]

Godot version: v3.1.beta1.official
OS: Ubuntu 18.10

This can easily be seen by having a camera around & moving it and on a node place:

func _unhandled_input(event: InputEvent) -> void:
	if event is InputEventMouse:
		print(get_global_mouse_position(), event.position, event.global_position)

Output eg.:

(2398.499023, 814.499573)(1918.499878, 742.499939)(1918.499878, 742.499939)

event.global_position == even.position is true.

Please add Godot and OS versions.

Try passing the event through make_input_local

Try passing the event through make_input_local

Yah, that doesn't solve the issue and it isn't a practical workaround. You'd have to catch the event in the Camera2D node, adjust it with make_input_local on the root node (or first node under root) which then has to be at least Node2D to implement make_input_local. It's complicated

Ah! I think this is related: #12175. Well to me this is counter intuitive. I expected that event.position/global_position works as it does for all other regular nodes. If it's relative to viewport (if I understand correctly), it should be named something like viewport_position or mouse_viewport_position (although I assume it's on touch and other input types too), but definitely not global_position which implies a position in the world.

I'm not sure if this is documented. Now that I think about it, it does make sense to have inside of _input & _gui_input positions in regards to nodes for which we override these functions. But the names are confusing and can't we have them all as properties of InputEvent? relative_position (relative to node using _input/_gui_input), viewport_position and global_position/world_position?

Can anyone still reproduce this bug in Godot 3.2.2 or any later release?

If yes, please ensure that an up-to-date Minimal Reproduction Project (MRP) is included in this report (a MRP is a zipped Godot project with the minimal elements necessary to reliably trigger the bug). You can upload ZIP files in an issue comment with a drag and drop.

(I tried it in 3.2.2 myself and seems fixed, but I could do something wrong. MRP would be really useful)

Bug still there, hope MRP will help

I don't mean to beat a dead horse, but this bug still exists in 2024 and is completely unmentioned in the documentation. I've been trying to get a mouse click working, following the current documentation. I finally found this bug report and this workaround of using make_input_local. This is extremely counterintuitive and since it is not in the documentation examples, nobody would ever think to do it. I am using 4.2.1 Stable I also imported the previous MRP into 4.2.1 and it still represents the issue correctly. Also of note, the workaround of using make_input_local(event) still doesn't make the global_position parameter the same as get_global_mouse_position(), once the camera has been moved from it's initial position.
In order to replicate the functionality of get_global_mouse_position() with events requires something like this:

func _unhandled_input(event: InputEvent) -> void:
    if (event.is_action_released("left mouse")):
        var local_event: InputEvent = make_input_local(event)
        var click: InputEventMouseButton = local_event as InputEventMouseButton
        var mouse_pos: Vector2 = click.global_position + get_viewport_rect().position + position

Hope this helps.
