Quietly Quietly is a server‑side silent container opening mod for Minecraft 1.21.1 ~ 1.21.10, supporting Fabric and NeoForge.
Its goal is simple:
Allow players to start silent container opening by Shift + right-click once
Display opening progress with a Bossbar
Keep container animations
Do not play vanilla container open/close sounds
Do not trigger vanilla CONTAINER_OPEN / CONTAINER_CLOSE sculk sensor events
Features Server‑side driven – the mod must be installed on the server; client installation is optional
Supports a generic silent opening process for all containers with an inventory GUI
Opening time is calculated based on the number of distinct item types inside the container
Retains animations for chests, barrels, ender chests, shulker boxes, etc.
Silences vanilla container open/close sounds
Blocks vanilla sculk sensor events related to container opening/closing
Built‑in English and Chinese localization
How to Use Look at a container with an inventory GUI.
Hold Shift.
Right‑click once with your main hand to start silent opening.
Keep sneaking until the Bossbar fills completely.
The container will then open silently.
Current Behavior Trigger method: Shift + right‑click once with main hand only
Must remain sneaking during the entire opening process
Releasing sneak, moving out of interaction range, or opening another interface will cancel the process
Opening speed formula: 12 + (number of distinct item types) * 4 ticks
"Distinct item types" means unique Item entries in non‑empty slots, not stack count
Supported Containers Any generic container that provides an inventory GUI
Vanilla containers with specifically handled animation and sound‑muting chains:
Chest / Trapped Chest
Barrel
Ender Chest
Shulker Box
Other GUI blocks (furnace, crafting table, hopper, etc.) also work with the silent opening logic
