 VoidAC is a **prediction-based anticheat** that simulates every possible player movement server-side. If a player moves in a way that is mathematically impossible, they get flagged - no heuristics, no guessing. It is a fork of [GrimAC](https://github.com/GrimAnticheat/Grim) and is **completely free and open source** under the GNU GPL v3. --- ## Discord / Support Join the community for support, false positive reports, and updates. [](https://discord.gg/e7WffFM6k3) --- ## What it catches | Category | Checks | |----------|--------| | **Movement** | Speed, Flight, Jesus, NoFall, Timer, Phase, Glide, Blink | | **Combat** | Reach, Hitbox expansion, Aim assist, AutoClicker, AutoTotem | | **World** | Scaffold/Tower, FastPlace, NoSlow, Baritone (auto-walk) | | **Packets** | BadPackets, PacketOrder, TimerLimit, AntiSpoof (fake client) | | **Exploit** | Freecam, MultiActions, Vehicle hacks, Elytra exploits | Geyser/Bedrock players are **always exempt** - no Bedrock false positives. --- ## Why VoidAC * **Simulation engine** - mathematically verifiable, not pattern-based. Speed hacks and flight are impossible to sneak past due to a 1:1 movement replication engine (covers everything from basic walking/swimming to riding entities). * **Low false positives** - the engine accounts for lag, ViaVersion, ViaBackwards, ping spikes, Optifine FastMath, and many other quirks. * **Latency & inventory compensation** - tracks inventory to prevent ghost blocks and queues world changes (like breaking blocks under players) until they reach the client, avoiding false flags. * **Full world replication** - maintains a compressed world cache (16-64 kb per chunk) per player to allow safe multithreading, prevent issues with client-side or fake blocks, and eliminate block glitching falses. * **No license key required** - drop the JAR in and it works. * **Multi-version & cross-version accuracy** - one JAR covers 1.8 clients all the way to 26.1, accurately handling client/server translation, missing blocks, correct collision orders, and minor bounding box changes across versions. * **Folia support** - runs natively on threaded-region servers. * **Lightweight & asynchronous** - all movement checks, the world cache, and the majority of listeners run entirely on the netty thread. Carefully designed for thread safety without main-thread overhead, scaling to hundreds of players. ## Punishment system VoidAC has a built-in punishment pipeline - no extra plugins needed (though LiteBans is supported for tempbans). - **Auto-punish** - kicks or bans automatically once a player hits a violation threshold. Configurable per-check. - **Manual punish** - `/void punish [duration]` with a customizable ban screen. - **Ban wave** - queue suspicious players and ban them all at once with a single command. Great for catching ban evasion. --- ## Anti-Xray & StorageESP VoidAC can configure Paper's built-in anti-xray engine automatically on startup. It also supports **Storage ESP decoys** - fake chest/barrel/shulker packets are sent to clients to confuse X-ray mods that reveal storage blocks. Both features are opt-in and configured in `config.yml`. --- ## Threshold Optimizer VoidAC includes an **adaptive threshold tuning system** that learns from real server data to automatically recommend optimal violation thresholds. This eliminates guesswork when configuring punishments. **How it works:** 1. Run `/void optimizer start` to begin collecting flag data 2. Grant trusted/legit players the `void.optimizer.legit` permission - their flags are treated as false positives 3. Let the server run for **24+ hours** with active gameplay 4. Run `/void optimizer stop` then `/void optimizer save` to generate recommendations 5. Review the generated `threshold-optimizer-report.yml` and apply thresholds to `punishments.yml` manually **Key features:** - **Safety multiplier** - recommends thresholds at 1.5× the highest legitimate flag to avoid false positives - **Per-check analysis** - each check gets independent recommendations based on actual player data - **Minimum sample validation** - ignores checks with fewer than 5 legit samples (insufficient data) - **Lightweight** - minimal CPU overhead; the optimizer is designed to run continuously **Available commands:** - `/void optimizer start` - begin collecting flag data - `/void optimizer stop` - stop collection (required before saving) - `/void optimizer status` - view real-time statistics (checks observed, sample counts, top flagged checks) - `/void optimizer save` - generate and save the recommendations report - `/void optimizer discard` - clear collected data without saving The optimizer is **opt-in** and controlled via the `threshold-optimizer.enabled` setting in `config.yml`. More features are waiting for you in VoidAC! --- ## Commands | Command | What it does | |---------|-------------| | `/void alerts` | Turn violation alerts on/off for yourself | | `/void verbose` | Toggle detailed alert info | | `/void profile ` | See a player's ping, version, brand, sensitivity | | `/void spectate ` | Silently spectate a player | | `/void history ` | View past violation sessions | | `/void debug ` | Upload a debug trace (for reporting false positives) | | `/void perf` | Check prediction engine timings | | `/void reload` | Reload the config without restarting | | `/void punish ` | Manually ban a player | | `/void banwave add ` | Queue a player for a ban wave | | `/void banwave execute` | Ban everyone in the queue at once | | `/void optimizer start` | Begin collecting flag data for threshold tuning | | `/void optimizer stop` | Stop threshold optimizer (required before saving) | | `/void optimizer status` | View optimizer statistics and real-time data | | `/void optimizer save` | Generate and save threshold recommendations | | `/void optimizer discard` | Clear collected optimizer data without saving | --- ## Configuration The config is generated on first start at `plugins/Void/config.yml`. VoidAC ships in **13 languages** - the language file is selected based on your server locale and written to `plugins/Void/` next to the main config. Available languages: English · German · Spanish · French · Italian · Japanese · Dutch · Polish · Portuguese · Romanian · Russian · Turkish · Chinese ## Credits & License VoidAC is a fork of [GrimAC](https://github.com/GrimAnticheat/Grim) by **MWHunter (DefineOutside)**, licensed under the **GNU General Public License v3.0**.
