Why

Players reported that armour and armour gems do nothing. Armour works. The floating damage number lies: MythicLib's damage indicator leaves out armour, so a hit reads the same on bare skin and in full Mythril.

Measured on Dev (Spellblade sword hits on a Warlord, inside /duel):

Target's armour Indicator before Health lost
None 6.4 6.21
Crafted medium Mythril, 12/4 6.4 3.70
Heavy Mythril, 18/10 6.4 1.99

What

TFMCCore holds each MythicLib damage indicator back for one tick and measures the health and absorption the target lost. It then rewrites the number and shows the line through MythicLib's own IndicatorConfig, so the icons, crit styling, number format and fly-out stay MythicLib's.

  • Hooks: AttackUnregisteredEvent at LOWEST records the target's health and the predicted damage. The DAMAGE IndicatorDisplayEvents inside that attack are cancelled and kept. The MONITOR end closes the attack.
  • Multi-part hits: a hit with several numbers (group_by: packet, on separate lines or joined into one) has each number scaled so they add up to the loss. Hits on one target in one tick share one measurement.
  • Zero-damage hits show nothing.
  • Kills show the health that was left.
  • Fallback: a line without a readable number (MythicLib custom_font) is shown unchanged.
  • Config: the number format and motion come from MythicLib's indicators.yml damage_indicators section, which is read again when the file changes.
  • Setting: accurate-damage-indicators in config.yml, default true. Live configs don't have the key, so it is on when the jar loads. false brings back MythicLib's number after /tcore reload config.
  • No MythicLib config change.

Tests

  • Local: mvn -o -B clean verify passes, 876 tests, line coverage gate at 0 missed. New tests:
    • IndicatorNumbersTest
    • RealDamageIndicatorsTest
    • MythicLibDisplayTest
    • the MythicLib case in PluginLifecycleCoverageTest
  • Dev: this jar (tfmccore-INDICATORS-25e03ac-DEV.jar). Bot test ~/armour-test-20261106/test2.js on tf: real character bots, attacker with a crafted Mythril sword at quality 100, victim with Archbishqp's Main build, inside /duel. Dev's RPCharacters pvp.yml/duel.yml were synced to Main's first.
Target Indicator now Health lost (bot reads it 1 s later, so about 0.2 regen is missing)
No armour 6.4 6.21
Crafted medium Mythril (Warlord) 3.8 (crit 6.2) 3.70 (crit 6.03)
Heavy Mythril with class bypass 2.1 1.99
Crafted heavy Mythril (Juggernaut, DR 15) 2.6 2.36
Fire Rain on medium Mythril, 6 ticks × 2 parts 5.2 each 5.15 per tick, read at the moment of the drop
accurate-damage-indicators: false 6.4 / 9.5 crit (MythicLib's number) 3.70 / 6.03

The Dev log has no TFMCCore errors. The startup error list matches the startup before the swap.

MythicLib builds its damage indicator from the damage event's final damage
while the event is still running, so armour never showed: on Dev a hit read
6.4 on bare skin and in full Mythril alike, while the target lost 6.21 and
3.70. TFMCCore now holds each damage indicator back for one tick, measures
the health and absorption the target lost, rewrites the number and shows it
through MythicLib's own IndicatorConfig, so icons, crit styling and motion
stay MythicLib's. Split indicators are scaled to add up to the loss, hits on
one target in a tick share one measurement, and a hit that took nothing
shows nothing. On by default; accurate-damage-indicators: false turns it off.

Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Review follow-ups: with split_holograms off MythicLib joins a hit's numbers
into one line, so every number in a line is rewritten now, not just the
last. The exact loss is only written when one attack showed one number;
otherwise a same-tick hit without its own indicator no longer adds its
damage to another hit's number. The current target is matched by UUID.

Summary

Summary by CodeRabbit

  • New Features
    • Added an accurate-damage-indicators setting, enabled by default. MythicLib damage numbers can reflect health lost after armour and absorption, appearing one tick after a hit. Hits that cause no health loss show no indicator; killing blows show the health remaining.
  • Documentation
    • Updated the feature list with details of accurate damage indicators.

The change adds a configurable MythicLib listener that captures damage indicators, measures target health and absorption loss on the next tick, then rewrites and displays the indicators. It also adds indicator number utilities, MythicLib display configuration handling, and related tests.

Changes: Accurate damage indicators

Layer / File(s) Summary
Configuration and MythicLib registration
src/main/resources/config.yml, src/main/java/net/tfminecraft/tfmccore/loader/ConfigLoader.java, src/main/java/net/tfminecraft/tfmccore/cache/Cache.java, src/main/java/net/tfminecraft/tfmccore/TFMCCore.java, src/test/java/net/tfminecraft/tfmccore/PluginLifecycleCoverageTest.java, README.md
Adds the enabled-by-default accurate-damage-indicators setting, loads it into the cache, and registers the listener with MythicLib when available. The README describes the displayed damage behaviour and setting.
Indicator formatting and display
src/main/java/net/tfminecraft/tfmccore/indicators/IndicatorNumbers.java, src/main/java/net/tfminecraft/tfmccore/indicators/MythicLibDisplay.java, src/test/java/net/tfminecraft/tfmccore/indicators/IndicatorNumbersTest.java, src/test/java/net/tfminecraft/tfmccore/indicators/MythicLibDisplayTest.java
Adds number counting and rewriting that preserve surrounding text and skip formatting tokens. The display adapter loads and refreshes MythicLib indicator settings, with fallback values when the section is absent or configuration loading fails.
Capture, measure and replay indicators
src/main/java/net/tfminecraft/tfmccore/indicators/RealDamageIndicators.java, src/test/java/net/tfminecraft/tfmccore/indicators/RealDamageIndicatorsTest.java
Captures matching indicators and schedules a per-target flush for the next tick. The flush measures health and absorption loss, applies threshold and scaling rules, then replays rewritten indicators.

Estimated code review effort: 3 (Moderate) | ~25 minutes

If indicators.yml is edited into invalid YAML, damage indicators silently revert to default formatting instead of keeping the last working settings. This is a minor cosmetic issue and does not block merging, but it is worth fixing.

Test listener discovery and dispatch ordering.

The helper calls the handlers directly. Removing an @EventHandler or changing a priority can leave these tests green while indicator capture fails. Add a dispatch test that exercises the pinned MythicLib producer and checks that the listener captures its indicator.

110-112: Minor · Potential issue · Heavy lift

Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.

Every attack's early predicted damage enters the shared scaling denominator, without later reconciliation for cancelled or rejected attacks. A same-tick attack that ultimately causes no damage can therefore reduce another attack's displayed number.

The first attack's 4 indicator is scaled by 2/8 and displayed as 1, although that attack actually removed 2 health.

This can occur when: One captured attack predicts 4 and loses 2 health; another attack on the same target predicts 4 at LOWEST but is subsequently cancelled and emits no indicator.


97-101: Minor · Potential issue · Heavy lift

Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.

Capture depends on an external event-ordering contract: every relevant damage indicator must be emitted inside AttackUnregisteredEvent dispatch, after onAttackStart and before onAttackEnd, and the health snapshot must precede damage application. The supplied production code does not establish that contract for MythicLib's attack paths.

Indicators on that path either retain their original inaccurate values or are cancelled and subsequently suppressed because the snapshot already includes the damage.

This can occur when: A supported MythicLib attack path emits its indicator outside that dispatch window, runs its indicator handler before this LOWEST handler, or fires AttackUnregisteredEvent after applying damage.


122-125: Minor · Potential issue · Low value

Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.

Indicator capture checks target-level pending state rather than whether the current attack was enabled. An attack started while disabled can still be intercepted when an earlier enabled attack has left pending state for the same target.

The disabled hit's original indicator is cancelled and rewritten despite the setting promising to leave MythicLib's number alone; its damage is also absent from the accumulated prediction.

This can occur when: An enabled hit creates pending state, the configuration is reloaded with accurate-damage-indicators false, and another hit on that target occurs before flush.

src/main/java/net/tfminecraft/tfmccore/indicators/IndicatorNumbers.java: 2

22-22: Minor · Potential issue · Low value

Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.

The number grammar assumes every comma is a decimal separator and supports only one separator. Configurable grouped number formats may therefore be split into multiple damage numbers or interpreted with the wrong magnitude.

The line is counted as two numbers and rewritten into incorrect damage values, rather than preserving the configured representation of one damage value.

This can occur when: MythicLib uses a decimal_format such as #,##0.0, producing 1,234.5 in an indicator.


45-48: Minor · Potential issue · Quick win

Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.

Numeric colour codes immediately followed by damage digits are matched as one number and then discarded as a colour code. For example, &76.4 contains colour &7 followed by damage 6.4, but the matcher treats 76.4 as the colour-code match.

The damage value remains unchanged instead of being rewritten to measured loss.

This can occur when: A MythicLib indicator format places a numeric colour code directly before its value, such as &7{value}.

src/main/java/net/tfminecraft/tfmccore/indicators/MythicLibDisplay.java: 2

54-56: Minor · Potential issue · Poor tradeoff

Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.

Replay re-enters IndicatorDisplayEvent processing for a message already processed by listeners during the original event. The local replaying flag only bypasses RealDamageIndicators; other message-transforming listeners may run twice.

Displayed indicators can contain duplicate decorations or twice-transformed numbers, rather than preserving the original styling and measured damage.

This can occur when: Another plugin's IndicatorDisplayEvent handler appends a marker, transforms a number, or performs another non-idempotent modification before this listener captures the original message.


36-43: Minor · Potential issue · Low value

Unverified finding
We couldn't verify this from the code. It is shown for review, not as a verified issue.

Changed configuration is passed directly into IndicatorConfig construction without preserving the last usable configuration on failure. A syntactically valid YAML edit with an invalid decimal format or another rejected setting may throw during replay after the original indicator has already been cancelled.

Scheduled flushes can fail and lose captured indicators repeatedly until the file is repaired, even if MythicLib itself retained its previous working configuration.

This can occur when: An administrator saves an indicators.yml edit that the pinned IndicatorConfig constructor rejects while damage indicators are active.

Exclude unrelated changes from the damage measurement.

If the target heals before the next tick, lost includes that healing. A 4-health hit followed by 4 healing shows no indicator. Uncaptured damage can also inflate the number. Track attack loss separately from other health and absorption changes.

Fixed in 5927cc3: the loss is now measured in segments. Every reported hit, other damage event and heal on a pending target ends the running segment, and only reported hits' segments count, so heals and unrelated damage in the same tick no longer change the number (an independent review suggested this over subtracting finalDamage, which leaves out armour and overkill). Tests: aHealBeforeTheFlushDoesNotMoveTheNumber, otherDamageInTheSameTickIsNotCounted, otherDamageThatKillsKeepsTheHitsOwnLoss. Verified on Dev with Regeneration V: the indicator stays at 3.8, the same as without regen.

@XxFran10xX Thanks for the fix. I checked the implementation and the three test cases. They cover healing and unrelated damage reported through events. I did not run the tests.

One limitation remains: a direct health or absorption change without an event can still affect the measured loss during a reported segment, as noted in RealDamageIndicators.java at Line 49. Is that limitation acceptable for this finding?

Review follow-ups (CodeRabbit and an independent review):
- Healing the target gets before the flush is added back and damage
  MythicLib did not report is taken out, so a regen tick or heal-on-hit
  no longer lowers or hides the number.
- A target removed while alive (despawned, logged out, changed world)
  shows nothing instead of its whole health; a kill still shows the
  health that was left.
- Colour codes are skipped as whole tokens, so &46.4 and &#ff00006.4
  still read 6.4, and MiniMessage tags are left alone.
- One shared flush per tick, and MythicLib's indicators.yml is checked at
  most once per tick that has indicators to show.
- A split part that scales down to nothing is dropped instead of "0".
- A test pins the handler priorities around MythicLib's listener.
- README and config.yml say absorption hearts count.

Review round 2 nits: a negative final damage no longer adds to the loss, and the docs say only EntityRegainHealthEvent heals are added back.

Review rate limited.

Note: CodeRabbit is an incremental review system and does not re-review already reviewed commits. This command is applicable only when automatic reviews are paused.

Independent review (standing in for rate-limited CodeRabbit) follow-ups:
- The loss is measured in segments: every reported hit, other damage and
  heal on a pending target ends the running segment and starts its own,
  so each health change is put down to the event that caused it. Armour on
  other damage, absorption and overkill no longer skew the number (a lava
  kill after a sword hit kept hiding the hit).
- An attack made while the setting is off is never held, even when an
  earlier hit on the same target is pending.
- A MythicLib indicators.yml TFMCCore can't use (invalid decimal_format)
  keeps the previous settings and is reported once per change, and one
  target's failure no longer drops the rest of the tick's indicators.

- Around line 43-45: Update refresh() to use a checked YAML load so it can
distinguish invalid syntax from a missing damage_indicators section; on parse
failure, retain the existing settings, while preserving the missing-file
fallback and defaults for a missing section. Add a test verifying invalid YAML
leaves the previous settings unchanged.

…ken YAML

CodeRabbit: loadConfiguration turned a YAML typo into an empty file, so the
defaults replaced the working settings. A checked load now tells a missing
file (defaults) from broken YAML (keep the previous settings, warn once).
Also pushes the attack before anything that can throw, so the MONITOR pop
always stays paired.

Findings fixed (replies on each thread; last fix 2d099de). CodeRabbit is rate limited on the latest commits, so an independent review stood in and approved 2d099de, per fran.
