AntiFly

LOGO

Lightweight Paper + Fabric flight-control plugin by CevAPI.

AntiFly is not a full anti-cheat. It focuses on flight and movement abuse with layered checks:

  • server-authorized flight state
  • server-side ground/support truth
  • buffered air/hover/anti-kick suspicion
  • disciplined setbacks to last known valid support
  • Elytra-specific movement and boost sanity checks

Platforms

  • Paper: 1.21.x -> 26.1.2
  • Fabric: 1.21.11 -> 26.1.2 (Fabric Loader 0.18.1+, Fabric API 0.141.1+1.21.11)

Commands

Paper

Requires op or antifly.admin.

Core:

  • /antifly enable
  • /antifly disable
  • /antifly status
  • /antifly help
  • /antifly exempt <player>
  • /antifly unexempt <player>
  • /antifly set
  • /antifly set <key>
  • /antifly set <key> <value>
  • /antifly reset <player>

Alerts:

  • /antifly alerts <off|game|console|both>
  • game alerts go to ops and users with antifly.alerts

Debug:

  • /antifly debug on
  • /antifly debug off
  • /antifly debug
  • Shows live action-bar telemetry (mode, speed vs limits, key buffers)

Fabric

Requires moderator-level command permission.

  • /antifly command family is available with equivalent core controls.

Primary settings keys (Paper)

  • groundWalkMax
  • groundMountedMax
  • waterMax
  • waterVerticalMax
  • maxAirHorizontal
  • maxAirVertical
  • bufferDecay
  • horizontalBufferLimit
  • verticalBufferLimit
  • hoverBufferLimit
  • noFallDetectionEnabled
  • airNonFallTicksLimit
  • antiKickWindowTicks
  • antiKickMinDescent

  • elytraEnabled
  • elytraBoostGraceTicks
  • elytraStallTicks
  • elytraMovementBufferLimit
  • elytraDurabilityCheckEnabled
  • elytraMaxRocketHorizontal
  • elytraMaxRocketUp
  • elytraNoRocketSustainableHorizontal
  • elytraMaxNoRocketUp

Legacy aliases kept for backward compatibility:

  • groundSpeed, groundSpeedWalking, groundSpeedMounted
  • waterSpeed, waterVertical
  • airSpeed, airVertical, airNonFallTicks
  • elytraMovementLimit

Notes on Elytra

  • Rocket-assisted glide is tracked separately from no-rocket glide.
  • No-rocket controlled upward/flat cruise behavior is treated as suspicious and can be blocked.
  • Rare fluid-exit and early-glide pull-up transitions are given short grace windows to reduce false positives.

Permissions (Paper)

  • antifly.admin (default: op)
  • antifly.alerts (default: op)

Config locations

  • Paper: plugins/AntiFly/config.yml
  • Fabric: config/antifly.json

1.0.8Релиз26.1.2 · 26 мая 2026 г.

Proper 26.1.2 Support.

1.21.11 likely won't continue for Fabric, but stay tuned.

1.0.8Релиз1.21.9, 1.21.10, 1.21.11 · 23 мая 2026 г.
  • Paper-side anti-fly detection got a major rewrite, with layered checks for ground support, air/hover behaviour, no-fall/anti-kick suspicion, and setback cooldowns.
  • Elytra handling was expanded with separate boost grace, stall detection, no-rocket glide sanity checks, movement buffering, and durability-based suspicion checks.
  • Added new admin controls for alert routing with /antifly alerts <off|game|console|both>.
  • Added /antifly debug so admins can toggle live action-bar telemetry for movement limits and buffer state.
  • Expanded /antifly status to show the newer config groups and current alert mode.
  • Added in-game alert permissions via antifly.alerts, alongside console/game alert routing.
  • Expanded /antifly set to support the new config keys, while keeping legacy aliases for backward compatibility.
  • Added live Modrinth version checking through /antifly status, plus startup warnings for admins if the installed version is outdated.
  • Brought the Fabric side up to match the newer detection and admin feature set, including alert modes, new settings, and version checking.
