robot.scrollMouse() moves the cursor to (0, 0) instead of scrolling

[branbarh]

Expected Behavior

Mouse should scroll

Current Behavior

Mouse does not scroll; instead, the cursor moves to (0, 0).

When used in conjunction with "setInterval," the mouse gets stuck permanently at (0, 0) (until ctrl+C is pressed in Terminal).

Steps to Reproduce

var robot = require("robotjs");

robot.scrollMouse(0, 10);

Running the above code on macOS (I am using High Sierra) causes the issue to occur.

Robot.js was the only Node module I was using.

Environment / Specs

• RobotJS version: Latest
• Node.js version: v12.16.1
• npm version: 6.13.4
• Operating System: macOS High Sierra (10.13.6)

For me robot.scrollMouse does not work at all. (Windows 10 here)

https://github.com/octalmage/robotjs/pull/508/files This issue seems to have been resolved. But it probably was reintroduced later on...

Edit: This really is the problem! It works on windows using the following steps:

• copy the lines 328 to 346 https://github.com/gera2ld/robotjs/blob/9dc6ff3e3a4bfe315ae242664fd6cd1408e1a40e/src/mouse.c#L328
  • paste it into the node_modules/robotjs/src/mouse.c file (override the same lines)
  • rebuild robotjs > npx electron-rebuild -f -t prod,optional,dev -w robotjs

Thanks to https://github.com/gera2ld who fixed it originally!

Same Problem here but only on Windows. For Mac it does work fine.
