Epic Parcool Momentum Log Killer

Epic Parcool Momentum Log Killer

Cancels epic_parcool_momentum's own internal diagnostic logging, which runs unconditionally on the client every single tick and was confirmed by decompile to cause severe, sustained TPS stalls. Movement mechanics are completely untouched — only the logging is removed.

Why this exists

epic_parcool_momentum's EPMClientHooks.logGliderOpeningDelayDiagnostic is the shared implementation behind 60+ call sites scattered across its wall-jump/glider/phantom-ascent handoff logic, almost all of which pass throttlePerTick=false. One of those call sites is reached from a @At("HEAD") mixin injected into GliderData#glideAndFallLogic — which runs every client tick for the local player regardless of whether they're actually gliding. Each unthrottled call does 10-20+ WeakHashMap lookups and derived capability/animation state reads before formatting a ~50-field log line, all before the log level is even checked. None of that data feeds back into any gameplay decision — the actual wall-run/glider/momentum state machine computes its own state independently — so this is pure, avoidable overhead paid every tick, all the time, whether or not the log level is high enough to actually write the line.

Features

• Cancels 6 of EPMClientHooks' internal diagnostic logging methods at their entry point via Mixin @Inject(at = "HEAD", cancellable = true): logGliderOpeningDelayDiagnostic, logGliderOpeningDelayProbe, logExhaustionPose, logGliderFastRunDiagnostic, logWomBackflipGliderGuard, logForcedDemolitionPhantomAscentBypass
• Zero effect on movement: wall-running, wall-jumping, gliding, phantom ascent, natural sprinter, demolition leap, spider techniques, and every other epic_parcool_momentum feature behave exactly the same — only the log calls are removed, and nothing reads their output back
• Client-side only

Requirements

• Minecraft 1.20.1
• Minecraft Forge 47+
• epic_parcool_momentum (required — this mod patches it directly and does nothing without it)

Notes

This is an unofficial third-party addon, not affiliated with epic_parcool_momentum's author. If a future version of epic_parcool_momentum renames or restructures these methods, this addon's Mixin targets may need to be updated to match.
