Player Heartbeat
by ErGali1898
Player Heartbeat, a Forge mod for Minecraft 1.20.1, makes a heartbeat sound and warning screen when other players come near in survival or adventure mode.
What it does
Nearby players are signalled by a heartbeat that grows faster as the distance closes. Three alert levels mark the approach, yellow at 70 blocks, orange at 45 blocks and red at 20 blocks, and the red level is shown with a PREPARE FIGHT prompt. Only players in survival or adventure mode take part in the heartbeat system; players in creative or spectator mode are hidden from the radar, set off no heartbeat and see no interface.
The mod is aimed at servers that want a tense atmosphere, such as PvP servers, UHC and Battle Royale events, and survival servers that add a layer of paranoia. Server owners can switch the system on or off for the whole server with commands. Player Heartbeat is a Forge mod for 1.20.1 only, and it runs on the client and the server, so both sides need it. Its code is All rights reserved and is not open source.
Key features
Three proximity levels
Yellow, orange and red alerts trigger at 70, 45 and 20 blocks, marking someone lurking and then getting closer.
Fair play logic
Only players in survival or adventure mode are tracked, so the system does not reveal creative or spectator players.
Admin controls
Commands let server administrators toggle the system globally for the whole server.
Immersive alerts
A heartbeat and warning screen tell a player when another player is nearby, adding tension to PvP and survival play.
