AAC protects your server from gamebreaking hacks and unfair advantages such as:
Kill-aura (attacks players/entities for you, huge combat advantage)
Reach (increases reach of hacker beyond fair vanilla reach of 3 blocks)
Fly (allows players to fly in survival, potentially at speed that will crash your server)
Other unfair advantages that harm your legitamate playerbase
:::caution Advanced Anti-Cheat is very user configurable, and as a result of this, is highly sensitive. Using the default configuration will result in false positives and is not recommended to be deployed in a production environment! :::
Install AAC by dragging it into your plugin folder, and restart your server.
Edit the config YAML to configure your commands to execute at a specific violation level.
:::important It's best practice to have a test server (even a local one if getting a hosted one isn't an option) to test your anti-cheat configuration before deploying ::: Here is an example snippet of AAC's config:
fastbow:
# Enable check? || true/false
enabled: true
lenience: 200
decay:
interval: 100
delay: 100
amount: 1
mitigation:
enabled: true
min_vl: 8
thresholds:
9: aacnotify %aac_player% is hacking!
13: aackick %aac_player%A "check" in an anticheat is a part of the plugin that analyzes if the player is cheating or not, or if they are displaying suspiscious interactions/behavior. In AAC, each seperate check in the config.yml can be individually configured, the above "fastbow" check being an example.
lenience: 200 is one of the "check-specific" configuration options, every check may have a different value that you can modify which specifically pertains to that check
The decay section of every check determines how much "VLs" or violation levels will go down (ms)
interval: 100 means every 100 ms, the violation level of a player will go down by the amount
delay: 100 how long to delay the decay of the violation level
amount: 1 how much the violation level decays
The thresholds section is pretty simple, it just determines what commands should be run when a player/potential-hacker reaches a certain violation level (VL)
See Conditional Commands for info on reducing lag related kicks/bans
See AAC Optimization Guide for a detailed and advanced explaination of what conditional commands are
:::tip Many server owners use Celebrimbor's optimized config, which costs an additional $14. This configuration consists of numerous optimized changes that Celebrimbor has made over the years, and it is highly recommended to get it as a base for you to use with AAC on your server. :::
No worries, AAC's configurability means that false positives are easily fixed. There are two types of false positives:
Plugin related false positives: report to AAC Github Issue Tracker so the developer can fix it
Configuration related false positives: false positives that you can fix
Fixing config related false positives:
First, collect some information on the false positive, like what might cause it and some verbose data
To collect verbose data, do /aac verbose and reproduce the false positive, or look in your AAC's plugin log folder
The verbose data will show what part of the check is causing the false positive, you can specifically focus on that part in AAC's config.yml, go to the config
Check your config values, perhaps add more leniency? Perhaps increase the violation level decay? Perhaps use conditional commands?
