SMP Utilities
SMP Utilities gives survival multiplayer server administrators tools to restrict items, blocks and entire mods, and to control specific mobs and players.
What it does
Administrators use the mod to restrict control over items, blocks and even whole mods on a server. Whitelists of specific players can bypass those restrictions. Items and blocks can be banned and later unbanned, and players who keep an item in their inventory still cannot use it while it is banned.
Three main control systems are provided for administrators, with a set of main commands. Mobs can be frozen or have their AI toggled, and a special weapon and sledgehammer are included for admin use, as described in the features. The mod aims to improve the experience of creating and running SMP servers.
Forge is the only loader with files, for 1.20.1. Curios API must be installed next to SMP Utilities. A server running it needs every connecting player to have it too. It is released under the CC0 1.0 Universal license and is not open source.
Key features
Item and block bans
Items, blocks and mods can be banned from use, and the same items can be unbanned later through the commands.
Attack-based player bans
Attacking without Mending kicks the player, while attacking with a Mending enchantment permanently bans them.
Mob freezing
Left-clicking a mob applies Slowness 255 invisibly, which freezes it in place for posing, decoration or screenshots.
AI toggling with the wrench
Right-clicking a mob toggles its AI and marks it with a MindWrenched tag, and a second use re-enables the AI and removes the tag.
Admin sledgehammer and unbreakable block
A zero-damage sledgehammer with extreme knockback sends entities far away without killing them, and an unbreakable block is meant for admin use.
