Stun Slam Simulator
This mod tells you the exact sub tick timing of your stun slams inputs to help you perfect your timing.
This is an information mod and does not affect gameplay. That being said it is NOT allowed in tier tests.
Downloading
- Find the releases section on the right panel
- download the .jar file into your mods folder (for 1.21.11 only!!)
- make sure you have the mods fabric api and mod menu installed
Usage
Go in game, get an axe and mace and press your stun slam hotkeys, it will automatically register inputs based on your hotbar slot.
This mod is designed with attribute swapping in mind and only counts tick perfect stun slams (for now).
The hard white lines are the times a tick happens on the client. The soft white lines at the bottom are when every client frame is rendered.
Some options are togglable with mod menu eg size.
The /stunslam toggle command can toggle HUD visiblity quickly.
