Social Isolation

Each player carries a social meter from 0 to 100. It fills while other players are nearby and drains while the player is alone, and new players start at 70. The meter is split into four tiers, and the effects of each tier scale with the level, applied without visible notice to the player.

Tier changes use hysteresis to prevent flickering. Moving up a tier happens instantly, while falling back needs a margin of 5 points past the threshold and 90 seconds of solitude, so brief separations do not cause repeated changes. Familiarity builds between pairs of players over 5 hours together and decays over 24 hours apart, and a group multiplier rewards larger groups logarithmically: 1.25x for two players, capped at 1.5x for four or more.

Processing is staggered across ticks, and the proximity checks avoid vanilla AABB queries where possible. Twelve server settings can be changed live through the social config set, without restarting the server. The mod is released under the MIT License and is not open source.
