Stun Slam Simulator
by MediocreSoup
Stun Slam Simulator gives mace PvP players a timing trainer that reports the exact sub-tick timing of stun slam inputs.
What it does
The mod is built around attribute swapping and counts only ticks in which a stun slam is perfectly timed. Hotkeys for the axe and mace register inputs automatically, based on the hotbar slot in use. Hard white lines mark the ticks when the game updates on the client, and soft white lines mark the bottom of the frame once it has been rendered, so a player can see both the logical and visual timing of each hit.
Practice runs can happen in casual queues, on practice maps, in tier tests and in competitive games, where the author states that the tool is allowed. Because it only provides feedback, it does not change how the game plays. Stun Slam Simulator requires Fabric API, and Mod Menu is optional; with Mod Menu installed, options such as size can be changed in-game. Files are published for Fabric only, for 1.21.11.
