Get Screen Dimensions

[ThisIsJohnBrown]

Having screen dimensions would be great for calculating where on the screen the mouse is or should be.

This could be returned as a new call in screen or returned with the object from getMousePos() so you would have x, y, width, and height parameters.

Another possibility is passing into getMousePos({percent:true}) and have it return 2 percentages rather than a fixed location { x: 50.44, y: 22.34 }
.

I think I'll create a new method for getting the screen size so it's not slowed down by getting the mouse position. The internal C function getMainDisplaySize() does what you want, it will be very easy to expose it to Node.js (with a new name).

I'll try to get this added tonight!

Sorry, thought I replied to this. I added getScreenSize:

var robot = require("robotjs");

var screen = robot.getScreenSize();

console.log(screen.width + "x" + screen.height);

I released RobotJS v0.1.2 with this function, update and let me know how it works!

Perfect! Thank you, @octalmage!

Good day.

the function to obtain the screen size in macOS does not operate, the result it shows is 0 in width as in height

`var robot = require("robotjs");

// Speed up the mouse.
robot.setMouseDelay(10);

var twoPI = Math.PI * 2.0;
var screenSize = robot.getScreenSize();
console.log(screenSize);
var height = 768;
var width = 1366;

for (var x = 0; x < width; x++) {
y = height * Math.sin((twoPI * x) / width) + height;
robot.moveMouse(x, y);
}`

I've got the same issue! Does somebody know how to solve this?

Same issue... any fixes?

If I use NVM to switch to Node v10.23.1 it works. (I use MacOS Catalina 10.15.7)
So apparently there was a change in NodeJS itself that broke robot.getScreenSize() and thus also mouse clicks? 🤔

Note: I didn't investigate at which version it started to break, v10.23.1 was just the one I already had in NVM.
