Robotjs: [multi-monitor] moveMouse wont move to negative position on mac

[bradparks]

Hey... I use getMousePos to get the mouse position, and it returns negative values sometimes (multiple monitors above my laptop monitor).

I then try and use robot.moveMouse(800, -954) for example, and it only moves to 800, 0.

@bradparks The negative mouse coordinates happen in a multi monitor setup. Basically anything left of your primary display may have negative coordinates.
As for the failing moveMouse did you try anything less than -954 ? If you had got (500 , -300) then you can go negative only on the y axis. Also you can only go till the screen max.

If you could provide more details on what you got from moveMousePos , what your arguments for moveMouse and the screen sizes , you can get a better answer.

The issue is that the code doesn't have explicit multi-monitor support, so anything that works is kind of on accident. I don't think this is an issue on Windows, but for Mac I'll need to look into it.

[Deltatiger]

I think this should be made uniform across all platforms. As you said it is still a hack in Windows. Should probably get the monitor sizes before making the mouse move or throw some kind of error. That would be better.

[octalmage]

I agree. I guess we'll need to start with adding c functions to get the number of monitors and their sizes.

Would be nice to have this!
Wish I could help.

any update of this?

I messed around with the code enough to get getPixelColor() working on Windows 10 with 2 monitors. However, in the process of doing so, I've discovered that getting multi-monitor support for every feature would be a massive undertaking. Just about everything in the src folder makes the assumption that the user only needs to operate within their primary display. In @octalmage's defense, though, it appears these files were forked from autopy—most of which haven't been updated in ~8 years.

This is the only really big issue I'm having with this library, really wish it was implemented

At the end I worked around this issue like this, after having done brew install cliclick (link)

const { exec } = require('child_process')
exec('cliclick c:.')

This helps ->Does not support multiple monitors #26
I install the robotjs with npm install git+https://[email protected]:Toinane/robotjs.git --save- dev and rebuild for electron. Find it support multi-screen now.
Thanks, @romanrandom.

The real work was from @jdan as you can see here : https://github.com/Toinane/robotjs/commits?author=jdan from his fork https://github.com/jdan/robotjs
But yes my fork will work too @Louis-7 👍

[Louis-7]

@Toinane thanks you for clarifying. Also like your color picker, it inspires me to build something for the designer.

@jdan, thanks!

Hi all, i truly love this library. I'm a little late to the conversation, but I ran into mouse movement issue for multiple external displays as well. I need to support it on multiple operating systems. Are we saying this is a limitation that needs to be accepted with RobotJS?
