KBMaster
by ruszek09
KBMaster shows where a mob will land after a hit, drawing a soul-fire pillar at the predicted spot so players can judge knockback before the next swing.
What it does
When the player attacks a mob, KBMaster calculates the distance the mob will be knocked and places a soul-fire pillar at the predicted landing point. The calculation uses a knockback multiplier, which defaults to 6.4 and is tuned to the current Minecraft physics. The multiplier can be changed in the configuration menu to match the conditions on a particular server.
The mod is a lightweight utility for combat practice and testing knockback behavior. Its visualization can be switched on or off at any time through a toggle, and the menu is provided in full English. It needs Cloth Config API for its configuration screen and Fabric API for the Fabric loader, so both must be installed alongside it. The mod is built for Minecraft 1.21.4 on Fabric only.
