I wrote a simple program that allows a player to auto-click while the Minecraft window does not have focus.

It allows you to do stuff like AFK fishing or AFK exp grinding while you browse reddit or anything else while the Minecraft window is in the background.

Clicker Window

You can view the source, or download the .exe from my github repo:

(Always recommended to run any .exe through VirusTotal to make sure it is safe)

Auto-Clicker

This is stated in the readme on github, but you will also need to set "pauseOnLostFocus" to "false" in your options.txt, otherwise it will not work.

To use it, simply do the action you want to repeat once and then bring up the menu (default Escape). Then click "Start" in the application!

When you want to stop, click "Stop" and it will stop the action and bring the menu up again.

Enjoy!
