OPAC Welcome Suppressor

by murder_spagurder

OPAC Welcome Suppressor stops the welcome messages that show up when a player enters or leaves an OPAC claim.

FabricForgeNeoForgeClient-side onlyMIT LicenseOpen source1.20 – 1.21.11

What it does

On servers with many small claims, the welcome messages sent every time a player crosses a claim border can get tiresome. This client-side mod filters out the action bar messages shown at the start and end of each claim visit, and nothing else changes on the server. It is released under the MIT License and is open source.

Key features

  1. Hides claim entry messages

    Suppresses the action bar message sent by the server when a player enters an OPAC claim.

  2. Hides claim exit messages

    Suppresses the matching message shown when a player leaves a claim, so the action bar stays clear.

  3. Client-side filtering

    The filter runs only on the player's client, so no server-side change is required for it to work.
