The Minecraft autocrystallizer is a macro that helps automate the process of placing and destroying crystals in the game. To activate the macro, hold down the right mouse button. You can adjust the speed of placement and destruction of crystals by changing the delay in the macro code. In the original version, the delay is set to a certain value so that actions with crystals do not attract unwanted attention.

I personally find this macro very useful and hope that it can be useful for you as well.

If you are interested, I have another macro that allows you to place obsidian at the click of a button. Please let me know if you are interested. I will be happy to provide you with this macro.
