About this Mod

This mod adds a delay to Command Blocks, exactly like in Bedrock Edition!

It adds a new box beneath the Command Console to allow to input a delay to when the command runs. There is also a button to make it execute on the first tick, but only for Repeat Command Blocks.

NOTE: Currently does not appear on the UI if mods that change the Command Block's UI are present. (Can still run fine)

Planned:

Compatibility with Better Command Block UI (possibly also Command Block IDE)
Option to still run if not powered after being pulsed by power such as redstone
Hover Note (possibly would be a different mod)

Frequently Asked Questions

Command Block Delay 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 (1.21.11). You can switch loaders with one click in the panel.

Is Command Block Delay compatible with fabric?

Command Block Delay officially supports fabric for Minecraft 1.21.11. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Command Block Delay – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if Command Block Delay 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.
