MLSAC b42 - plugin update
❗️IMPORTANT UPDATE!

[ ~ ] Animations - Fixed animation duplication (It is very important to update the plugin!)

[ ~ ] Geyser Support - Support has been finalized so it works even with Floodgate
[•] ban-handler fix
[ ~ ] Animations – a new animation engine is now available. The animations folder also includes a special prompt for neural networks so you can insert it and vibe-code your own animation.
[ ~ ] Compatibility – the plugin is now more performant due to internal changes. It is now compatible with 1.21.9 and above.
Even when packet cancellation occurs, the plugin will still receive them, which eliminates issues when using multiple plugins such as MLS and Grim on a server.
[ ~ ] Data processing – fully rewritten from unsigned to signed data. Only this version of the plugin and newer will support the updated and new models.
(Without updating, the plugin will remain permanently on the old model.)
[ ~ ] Sleep mode – when you exhaust your limit, it will no longer spam or increase ping; it will gently go to sleep and periodically check in.
[ ~ ] Action prefixes – in punishment settings we no longer use {BAN} {KICK}; now we use {ANIMATION}.
[ + ] Status – a full /mlsac status command has been added to monitor API response times, detections, and requests overall.
[ + ] Monitoring – with the new /mlsac monitor command, you can track all PvP on the server and receive notifications for any probabilities, even below the threshold.
[ + ] Animation testing – quick preview of animations on
a player.
Main New Features:
Auto-Updates — automatic update system now in testing phase, delivered via MLS servers (prevents connection drops). Can be disabled in config.
Full Interserver System — links multiple servers together through MLS infrastructure, no extra database setup needed. New config fields:
* server-identity.name — unique name per server
* server-identity.family — shared name to group servers together
* interserver.enabled — toggle the system on/off
Webhooks & Telegram — now manageable directly from the web panel per server, with options to trigger on interserver events or local only.
Bug Fixes:
* Fixed hologram and ban animation issues
* Fixed two detection models overriding each other's results
Steps to Update:
1. Delete your old messages.yml
2. Run /MLSAC REINSTALL on all servers
3. Reconfigure the new settings as needed
