serverpermadeath

this mod runs on the server only. The goal of this mod is to give server authority / no client mod solution to permadeath. We don't want to use the originally bannedlist.txt because that will ban a player all together. We want players to continue playing, they just can't use a character that has died.

new server textfile permadeath.txt

Server checks for dead players. if a player dies:

• adds steamid|charactername to permadeath.txt
• shout that player has died
• start a 30 sec timer giving them time to say goodbye
• kicks them, shows Banned popup

Server checks permadeath.txt and all players connected. if player|charactername is on list:

• kicks them, shows Banned popup

Combine this with servercharacters https://valheim.thunderstore.io/package/Smoothbrain/ServerCharacters/ to have a hardcore server

install

prerequisite: have bepinex installed on server

drag serverpermadeath.dll into bepinex/plugins folder

restart server
