# Check Types

## Movement Checks

| Check         | Config ID        | Description                                                                                                                                                               |
| ------------- | ---------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Speed         | `speed`          | Detects players moving horizontally faster <br />than their current movement conditions allow. <br />It accounts for effects and common <br />legitimate movement states. |
| Fly           | `fly`            | Detects sustained movement or hovering <br />in the air without flight, a vehicle, <br />or another legitimate cause.                                                     |
| Glide         | `glide`          | Detects players falling substantially <br />slower than normal without a <br />valid slow-falling or gliding condition.                                                   |
| Step          | `step`           | Detects players climbing blocks <br />with an upward step larger than <br />normal Minecraft movement permits.                                                            |
| HighJump      | `high-jump`      | Detects a player rising significantly higher than <br />a normal jump without an allowed effect or <br />movement source.                                                 |

| WaterWalk     | `water-walk`     | Detects sustained movement on <br />top of liquid as if it were solid ground. <br />Liquid-entry and exit grace reduces false flags.                                      |
| NoFall        | `nofall`         | Detects players avoiding expected fall damage <br />or falsely reporting a safe landing after a <br />significant fall.                                                   |
| GroundSpoof   | `ground-spoof`   | Detects a client claiming to be on the ground while <br />the server sees no valid supporting block.                                                                      |
| InventoryMove | `inventory-move` | Detects movement while an inventory interface <br />is open when that movement should not be possible.                                                                    |
| Timer         | `timer`          | Detects clients running game movement ticks faster <br />than the normal Minecraft tick rate.                                                                             |

| KillAura    | `killaura`     | Detects suspicious automated combat patterns,<br /> including rapid target switching and multi-target attacks.            |
| AimAngle    | `aim-angle`    | Detects attacks where the player's view direction is too<br />far away from the target.                                   |

| ----------------- | -------------------- | --------------------------------------------------------------------------------------------------------------------------------------------- |
| FastPlace         | `fastplace`          | Detects blocks being placed faster than <br />the configured minimum placement interval.                                                      |
| AirPlace          | `air-place`          | Detects blocks placed without an <br />adjacent supporting block, which <br />normal placement does not permit.                               |
| BlockReach        | `block-reach`        | Detects block placement from farther <br />away than legitimate interaction range.                                                            |

| FastBreak         | `fastbreak`          | Detects blocks being broken faster than<br /> expected for the block, tool, effects, <br />and player state.                                  |

## Player Action Checks

| Check        | Config ID       | Description                                                                                                          |

| --------------- | ------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| PacketTimer     | `packet-timer`      | Counts movement packets per second and <br />detects clients sending them faster <br />than the expected tick rate.                                            |

| --------------- | ------------------ | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| BehaviorAnomaly | `behavior-anomaly` | Combines multiple behavior samples to <br />identify a player whose overall movement <br />or combat profile differs significantly <br />from normal play. It is a supporting risk signal <br />rather than proof by itself. |

## Client and Anti-Spoof Checks

| Check              | Detection ID      | Description                                                                                                                              |

| HackingMod         | `hacking-mod`     | Matches exposed client brands, mod names, channels, <br />and payload hints against configured hacked-client<br />patterns.              |
| BlockedChannel     | `blocked-channel` | Detects a registered plugin channel matching a <br />configured suspicious or forbidden channel pattern.                                 |
| BrandSpoof         | `brand-spoof`     | Evaluates the client-reported brand against <br />configured known and suspicious brand patterns.                                        |
| ModDiscrepancy     | `mod-discrepancy` | Detects inconsistent signals, such as a Fabric or Forge <br />brand without the channels normally exposed by <br />that loader.          |
| Client fingerprint | Informational     | Records the brand, detected loader/client, protocol<br />version, client settings, channels, and custom <br />payloads for staff review. |

# Important

* Client brand, channel, and fingerprint information can be hidden or spoofed by modified clients.
* A detected client or mod loader does not automatically prove cheating.
* Client fingerprints should support movement, combat, packet, and behavior evidence rather than be used as the only ban reason.
* Check thresholds, buffers, violation amounts, and kick levels are configured under `checks.<config-id>` in `plugins/SMP/Anticheat/config.yml`.
