Random Tick Control
by PAWE404
Random Tick Control lets server owners choose which blocks receive random ticks, from the default vanilla behavior to blocks that never tick at all.
What it does
Random ticks drive behaviors such as melting, growing and spreading. Random Tick Control adds a configurable block list, so a server can keep those behaviors for some blocks and prevent them for others. By default the mod matches vanilla behavior, and every setting can be changed in-game through the mod menu. After a change, the config must be reloaded before it takes effect.
Blocks can be set to never random tick, to ignore the random tick event, or to always random tick, which keeps them experiencing random ticks even in states that normally block them. Most crops stop experiencing random ticks once they mature, and the mod can change that, which may interfere with other mods or scripts that rely on the vanilla rule. The mod is server-side only and is published for NeoForge 1.21.1 only, under the MIT License, which is not open source.
Key features
Per-block random tick control
Each block can be set to follow vanilla, never random tick, or always random tick.
In-game configuration
Settings are reachable through the mod menu, so changes do not require editing files by hand.
Random tick event hook
Blocks set to ignore random ticks skip the event, and blocks that still receive it can be handled by other code.
Low performance cost
Using the mod to disable blocks that cause lag in random tick mechanics can reduce load, and the mod itself adds little overhead.

Use cases
Stopping costly random ticks
A server owner can disable random ticks on blocks that cause lag, leaving the rest of the world unchanged.
Keeping crops growing
Mature crops can be set to keep experiencing random ticks, which matters for farms that rely on continuous growth.
Who it’s for: Server owners who want to tune random tick behavior per block, and modpack authors who need crops or spreading blocks to behave differently from vanilla.
How it compares
Random Block Area is a NeoForge mod for 1.21.1 – 1.21.11 that runs on client and server and is closed to modification under All rights reserved, so it is a different kind of tool. Block Destroy Entity Drop is also a NeoForge mod for 1.21.1 only, but it is server-side only and works on a different mechanic, block destruction. Random Tick Control is server-side only, MIT licensed and not open source, so only the server needs it.

By default, the mod matches vanilla behavior. The config, which can be accessed in-game through the mod menu, allows you to choose the random tick behavior. If your config changes aren't working, just run /reload! A block set to never random tick will ignore the random tick event. Random block behaviors such as…
