How to Knock on Doors to Alert Other Players

Approaching a Base Entrance

When visiting another player's residence or base, walk directly up to their exterior door. Position your character close enough to reach the door block within standard interaction range. Make sure you are facing the door directly rather than adjacent wall blocks.

Signaling Occupants Inside

Perform the knock action against the door to create a signal for whoever is inside the building. This mechanic simulates real-life social behavior, alerting the occupant of your arrival without requiring you to barge into their personal space or open their door unannounced.

If the player inside is busy crafting, managing storage chests, or working near noisy workstations like furnaces, perform another knock on the door to ensure they notice your presence at the entrance before you attempt to communicate further.
