About this Mod

TNT Optimizer

This thing helps with explosions in the game by using a special way to look at the blocks that are going to be affected. It does this to help the server run smoothly when a lot of things are happening at the same time.

How it works:

Normally the game checks the blocks over and over again.. The TNT Optimizer uses a different method to look at each block only once. It also keeps track of which blocks it has already checked. If there are a lot of explosions happening at the same time it does not do the same work twice.

Features:

  • It looks at each block once when something explodes

  • If there are a lot of explosions happening in the area it does not check the same blocks more than once

  • If you just have one TNT with nothing, around it it explodes away without using any extra resources

  • The way the game works normally is not changed. The explosion is just as big. Does just as much damage

  • You only need to install this on the server. All the players can play without having to do anything extra

This helps the server run better. It does not make the TNT explode any faster.. If you are playing by yourself the server will run better and that might make the game less slow when a lot of TNT explodes at the same time. The way things look on your screen like the particles is not affected.

Compatibility:

  • Minecraft 1.21.11

  • Fabric Loader 0.18.1+

  • You need to have the Fabric API for this to work

Frequently Asked Questions

TNT Optimizer server crashes on startup – what to do?

Is TNT Optimizer compatible with fabric?

TNT Optimizer officially supports fabric for Minecraft 1.21.11. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with TNT Optimizer – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if TNT Optimizer consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge.
