Why is mouse position always (0,0)?

[zReticulan]

When I call GetMousePosition on the player controller, the return value is always 0,0. This is happening on a Windows 11 PC running UE 4.26. I don’t see anyone else experiencing this online so I’m asking here: what could be the cause of this?

Hi @zReticulan !
yes because it points always to 0.0, perhaps what you want is the camera!

[dorusoftware]

is a bit more tricky than calling that node to get the position.

you can watch this video that should explain a lot of stuff. basically you are asking for the mouse position in the wrong place. the mouse is sending the x and y position to the UI not to the game

[alberto]

Yeah but then the cursor is active and not the game!
Unless we want that of course

[dorusoftware]

if you ask for the mouse position from the correct input mode it will send it. mouse cares about the ui or about the game or both if I recall correctly.

ok the other one I think is:

good try @dorusoftware

[zReticulan]

That’s not quite what I mean. The Return Value of the Get Mouse Position node is always false.

[alberto]

It will be always 0 because is always pointing 0, what you are moving in game is the camera

If you want to show the cursor and get position:

@dorusoftware

calling that node to get the position

If you want the camera coordinates:

And perhaps a screenshot of how it looks the project will help us to help you…
Are you creating a first person, third person…?
what do you want to do with cursor position…

[zReticulan]

This project uses a custom game mode. It’s not first or third person. The mouse cursor is visible when I move it around the game viewport, but Get Mouse Position still returns false.

@zReticulan

he mouse cursor is visible when I move it around the game viewport, but Get Mouse Position still returns false.

so you are moving the cursor like in windows, not like in call of duty:

How to get mouse position in screen space?

It’s a hud widget that is telling you an inventory items info when you put your cursor over it. For something like that I’d just use the built-in tooltips: [298815-widgettooltip.png] [298816-toolt.png] [Image from Gyazo] You can then easily pipe in data from the item’s widget into the tooltip widget.

That’s right. In addition, when I load the same project with all files being identical, the GetMousePosition node works as expected, and the proper coordinates of the mouse cursor are printed.

[zReticulan]

I figured it out. It turns out the computer, which I was connecting to via TeamViewer, didn’t have a mouse connected.

[dorusoftware]

that is a big piece of information you left out from your question. That you are using unreal using a remote computer.

lol

[zReticulan]

I do it so often I didn’t even consider it would be the cause but now I know Unreal needs a mouse physically connected even if the cursor is being moved around without it
