JumpReset

Accurate jump-reset feedback for PvP — powered by pre-physics velocity analysis.

JumpReset is a client-side Fabric mod that gives you accurate, real-time feedback on your jump resets during PvP combat.

A jump reset is the technique of jumping immediately after taking a hit to cancel the knockback. Its effectiveness depends entirely on timing — jump too early and the game hasn't registered the hit yet; jump too late and the knockback has already been applied. The ideal window is roughly 80 ms after impact.

Most mods read velocity after the physics engine has already processed it, making it impossible to reliably tell the difference between an intentional jump, knockback-induced motion, and terrain. JumpReset hooks into the engine before physics resolution, capturing the raw velocity impulse at the exact tick it is produced — so every result you see is honest and consistent.

Features

Detection

• Pre-physics velocity capture — never confuses knockback, slopes, or fall decay with a real jump
• Dynamic timing windows — separate windows for ground and air state
• Automatic ping compensation — both the hit timestamp and all classification thresholds shift based on your measured latency
• Combat filtering — falls, fire, and poison damage are filtered out; only knockback-qualifying hits count

Feedback

• Five classifications: PERFECT · GOOD · LATE · TOO EARLY · MISSED
• Gaussian scoring curve — every attempt gets a 0–1 score, not just a label
• Crosshair indicator — a colored triangle above your crosshair shows when the window is open (yellow) and the result of your last attempt (green / red), so you never look away from the fight
• Coaching hints — short tips ("slightly late", "perfect!") tell you how to adjust

HUD — three display styles

• Minimal — a small pill label, lowest visual footprint
• Detailed — full panel with classification, ms readout, coaching hint, score bar, and a history strip of your recent attempts
• Timing Bar — a horizontal bar with zone markers and a moving marker showing exactly where your jump landed relative to the perfect zone

All styles feature smooth slide-in animations, drop shadows for readability on bright backgrounds, and adjustable scale, opacity, and display duration.

Session statistics

Your performance is tracked across the whole play session:

• Hit rate (percentage of attempts rated PERFECT or GOOD)
• Current and best streak
• Per-classification counts and average score
• One-click reset button in the settings screen

Configuration

• Press K anytime to open the in-game settings screen (toggle the mod with J)
• Style-aware settings — the Display tab only shows options relevant to your active HUD style
• Live, draggable preview — the settings screen renders your actual HUD style and lets you drag it anywhere on screen
• All timing thresholds, colors, indicator size, and debug options are adjustable in-game
• Sensible defaults tuned for a typical 30–80 ms connection — no setup required

Compatibility

Minecraft	1.21.11
Loader	Fabric ≥ 0.18.0
Fabric API	Required
Java	21
Side	Client-side only

Works on any server — vanilla, Paper, Fabric, or otherwise. No server installation needed. JumpReset is read-only: it observes your movement but never modifies packets or gameplay, so it is safe to use with standard anti-cheats.
