StepItUp
The StepItUp mod offers smooth automatic block stepping instead of the standard Auto Jump feature in Minecraft. This is a simple and fast solution that works exclusively on the client side.
Configuration
The configuration file is located at config/stepitup.json5 in your Minecraft game folder. In the settings, you can enable or disable the automatic stepping function, as well as configure its operation during sneaking (applying these changes requires restarting the game).
For convenience, it is recommended to use some mod with a settings menu that will allow you to change parameters dynamically without the need to restart the game.
