Lock On
Lock on to enemies, ported to Fabric!

About this Mod
Mostly based on and ported to Fabric from Lock On.
Parts of the mod were rewritten to accommodate special features and configuration options.
This mod adds two new keys to Minecraft. One to lock on to nearby monsters (and Interaction entities, in case of server plugin custom mobs) and another to switch between multiple targets.
Going too far away or killing the target will leave lock-on mode.

Lock On server crashes on startup – what to do?
Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.20.4). You can switch loaders with one click in the panel.
Is Lock On compatible with fabric?
Lock On officially supports fabric for Minecraft 1.20.4, 1.20.3, 1.20.2. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with Lock On – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Lock On consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
