Keybind placement fixer
This mod resolves a Minecraft issue in which binding the Attack/Destroy action to any key other than left or right click incorrectly triggers anticheat systems for fast break detection.
About this Mod
This Minecraft mod fixes a long-standing compatibility problem between custom keybinds and server-side anticheat systems.
By default, Minecraft uses left click for attacking and right click for interacting or placing blocks. But many PvP players remap the Attack/Destroy action to other mouse buttons or keyboard keys. The issue is that some anticheat plugins don’t handle these remapped inputs correctly and can mistake them for FastBreak or other suspicious behavior.
The mod resolves this by making sure all valid inputs for the Attack/Destroy action are recognized the same way the game would handle default controls. It keeps input timing consistent with vanilla behavior so that remapped controls don’t create unusual packet patterns that could be misinterpreted by anticheat systems.
In practice, this means players using custom keybinds, accessibility tools, or alternative setups get a more reliable experience without being falsely flagged.
