Combat Metrics (Client-Side PvP Telemetry)

Most Minecraft PvP improvement happens by feel. You lose a duel, blame lag, queue again, and carry absolutely zero data from one fight to the next. The few tools that do exist are server-side plugins that just count kills and deaths. They don't tell you why you lost.

Combat Metrics changes that. It is a completely client-side Fabric mod designed to watch your combat mechanics the way a coach watches game film: silently during the fight, analytically after it. It modifies zero gameplay, sends no packets to the server, and works identically on public multiplayer networks, LAN duels, and singleplayer practice worlds.

What It Measures

Combat Metrics classifies your fight based on the kit you are holding (Sword, Axe/Shield, or Crystal) and tracks specific, high-fidelity mechanical metrics.

General Combat Metrics

• Swing Accuracy: The exact ratio of confirmed entity hits to total weapon swings. Whiffs count against you; mining blocks never does.
• Damage Taken: Total hearts lost during the session.
• Best Combo: The longest run of consecutive hits landed without taking damage back.
• First Hits: Tracks individual "engagements" (when an opponent gets within 3 blocks and leaves past 5 blocks) and tallies who landed the first blow of that exchange.

Melee (Sword & Axe) Metrics

• Attack Discipline: The percentage of swings thrown with your attack cooldown fully charged. The ultimate diagnostic tool to cure spam-clicking.
• Crit Rate: The percentage of your landed hits that were jump/falling critical hits.
• Average Hit Range: Measures the eye-to-impact distance of your hits, helping you gauge your spacing.

Crystal & Anchor Metrics

• Setup Speed (The Two-Tap): The delay (in milliseconds) between placing your obsidian/anchor and placing the crystal/glowstone on top of it.
• Totem Re-equip Time: Starts counting the frame your totem pops and stops when a new one is successfully in your offhand.
• Defense Response: Measures the delay between an opponent's action (like placing a crystal near you) and your defensive counter (raising a shield, placing a block, or popping their crystal).

The Interface

1. The Defeat Wrap

When you die in combat, the vanilla death screen is replaced with an elegant analytical wrap. It displays your overall performance grade (S, A, B, C, or F), highlights your weakest metrics in red, and provides a single, targeted Training Drill to focus on in your next match (e.g., "Respect the 1.9 cooldown: stop swinging before your crosshair indicator is full").

2. In-Game Graph Browser

Press the graph keybind to open your fight history. Each fight is visually mapped out:

• Health-over-time curves showing exactly where you took damage.
• First-hit timelines indicating who controlled the pace of the engagements.
• Setup-speed charts showing if your crystal placement slowed down as the fight dragged on.

Is this allowed on competitive servers?

Yes. Combat Metrics is entirely visual and diagnostic.

• It does not automate shield blocks, totem swaps, or placements.
• It does not send any packets to the server.
• It does not bypass vanilla client restrictions.
• It simply observes raw client-side inputs and events (like health changes and entity spawns) to calculate metrics post-fight. It is as safe to use on Hypixel, PvP Legacy, or MCCI as a standard FPS overlay.
