Universal Tweaks
by ACGaming
Universal Tweaks gathers a set of Forge bugfixes for Minecraft 1.12.2 into one mod, with each change switchable in a config file.
What it does
The mod is a consolidation of many small fixes and adjustments that were previously shipped as separate patches. Its changes cover rendering, combat, block interaction and item behavior, among them smooth lighting accuracy, anvil repair rules, hostile mob attack radius, shield handling and block selection boxes. Every change can be turned on or off through the mod's config files, so a server owner can keep only the fixes a pack needs.
The project depends on ConfigAnytime and MixinBooter, both required on Forge 1.12.2 before the mod will load. Tek N Astra (Sea of Dreams) requires it as well. Installation covers the server and each player's game. Files are published for Forge only, and the latest build is 1.21.0 for 1.12.2, released in September 2026. The code is under the GNU Lesser General Public License v3.0 only and is open source.
Key features
Smooth lighting accuracy
Smooth lighting is corrected by checking for suffocating blocks and light opacity around each corner.
Anvil repair check
Anvils are prevented from repairing items that should be irreparable.
Hostile mob attack radius
Mobs measure their attack range with a line-of-sight raytrace, so attacks stop at walls they cannot reach through.
Shield fire blocking
Fire projectiles no longer set entities alight when the player blocks them with a shield.
Block overlay and selection
The x-ray effect when standing in non-suffocating blocks is fixed, and mouseover selection boxes line up with their blocks.
