A Mimir

by giran

A Mimir gives players a rewarding night after sleeping, with timed status effects applied when they wake up.

FabricServer-side onlyCC0 1.0 Universal1.21.11

What it does

After a player sleeps and wakes, the server applies a set of configurable status effects for a limited time, so the wake-up leaves the player with a buff going into the new day. Default buffs are included, and the absorption strength and duration can each be changed. Each effect's timer can be fine-tuned in seconds, and the morning rush length is adjustable, with 60 seconds as the default.

The mod is server-side only, so players join without installing anything, and only the server needs it. A config file, config.json, lets the server owner tweak almost every part of the behavior, including turning the whole mod off or disabling the wake-up sound. Wake-up messages can appear in the action bar above the hotbar or be announced in global chat, and a random high-energy tag such as WIRED, LOCKED or OVERCLOCKED can be added to the message.

Installation needs Fabric; the mod is published for Fabric only, in one release for 1.21.11. The code is covered by CC0 1.0 Universal, a public domain dedication, and the project is not open source.

Key features

  1. Configurable wake-up buffs

    Status effects such as speed, regeneration and absorption are granted when a player wakes up, and the server chooses which ones.

  2. Adjustable effect timers

    Each buff has its own duration in seconds, and the morning rush can be shortened or lengthened from the config file.

  3. Action bar and chat messages

    Wake-up text can show above the hotbar or be sent to global chat, with a random high-energy tag added to the message.

  4. Global chat announcement

    When the night is skipped, a message can be broadcast to all players, naming the player who slept.
