How to Get Auto-Click on "Minecraft"by Matthew VehonUpdated September 22, 2017
AutoClick is a third-party add-on for the game Minecraft. It allows players to use a hotkey to simulate the left mouse button being held down. The left mouse button is used to mine through blocks of stone and ore in Minecraft. The button must be held down to destroy the block and collect the ore. AutoClick allows players to tunnel through vast caves without the hassle of constantly holding down the mouse button.
Download AutoClick (see "Resources"). Run the saved file to install the program.
Follow the instructions on the installation prompt.
Open AutoClick. Run Minecraft and enter a saved game. Click the screen once to set the pointer.
Press "F3" to start AutoClick. When you want to turn it off, press "F3" again.
The key binding for AutoClick is set to F3 by default. In Minecraft this brings up the player's coordinates, so you may want to change the binding in the "AutoClick Hotkey" box of AutoClick.
