About this project
What does FastBoth add?
FastBoth is a small mod that gets rid of the annoying delay between breaking and placing blocks so you can build and mine way faster than usual
It adds a simple menu you open by pressing P where you can flip on Fastbreak and Fastplace separately depending on what you need at the time
Fastbreak lets you chain block breaks back to back with zero waiting
Fastplace lets you spam place blocks just as fast as you can click
Your settings save automatically so you don't have to turn them back on every time you open the game
Built for Minecraft 1.21.11 using Fabric and it needs Fabric API installed to work
