vrobot

⚠ Work in progress. Only Windows is supported.

Basic desktop automation functions for V lang. PRs welcome :)

Plans

• [x] Add more mouse easing functions, currently it only has linear
• [ ] Screen related functions
  • [x] screen_size()
  • [x] pixel_color()
  • [ ] locate_on_screen() For colors and images
• [ ] Keyboard simulation and hooks
• [ ] Linux support, not priority currently

All ideas are welcome!

Example

import vrobot

// Print mouse position
pos := vrobot.mouse_pos()
println('Mouse position: $pos.x, $pos.y')

// Print pixel color at (100, 100)
color := vrobot.pixel_color(100, 100)
println('Pixel color is: ($color.r, $color.g, $color.b)')

// Print screen resolution
screen := vrobot.screen_size()
println('Screen size: $screen.width, $screen.height')

// Moves mouse twice and returns to starting position
vrobot.move_mouse(pos.x + 100, pos.y + 100)
vrobot.move_mouse_smooth_rel(-100, -100, 500, 'linear')

// Drags from (100, 100) to (150, 150) with left click
vrobot.move_mouse(100, 100)
vrobot.drag(150, 150)

🖱️ Valid mouse buttons are: left, right, middle
