Hotbar Trainer
by tvmaiker
Hotbar Trainer is a single-world reaction trainer that asks players to switch to hotbar slots as fast as they can, with the start key set to H by default.
What it does
Once a player joins a singleplayer world and presses the start key, a self training hotbar drill begins. Once a randomized wait has passed, a large slot number is drawn above the crosshair along with a sound cue, and the player must switch to that slot. Each prompt is timed, and the reaction time appears in a color-coded readout after each switch, so the player can see how quickly the switch was made.
The base delay between prompts can be set anywhere from 100 to 3000 milliseconds, and random jitter keeps the rhythm from becoming predictable. The slot range can be narrowed so that only chosen slots are trained, and repeat avoidance prevents the same slot from being prompted twice in a row. The drill keeps going until the start key is pressed again, at which point a session summary is printed. Sound cues and the stats HUD can each be toggled, and the start key can be rebound. The mod is designed for players who train fast hotbar selection for combat with pearls, golden apples, crystals and totems.
Key features
Randomized slot prompts
A large slot number appears above the crosshair after a randomized delay, so the timing of each prompt is not known in advance.
Adjustable prompt speed
The base delay between prompts is set between 100 and 3000 milliseconds, with random jitter added on top.
Slot range selection
Only the slots the player chooses are included in the drill, so training can focus on the items used most often.
Session summary
Pressing the start key again ends the drill and prints a summary of the session in the chat.

How it compares
Priority is a Fabric mod that runs client-side only, with the MIT License, and is not open source; it covers 1.21 – 26.3. SwapColumn is also client-side only and under the MIT License, and it is open source; it covers 26.2 – 26.3. I Want More Hotbars! is client and server, under All rights reserved, and covers 1.21.10 – 1.21.11, so it changes the hotbar itself rather than training its use.
