Om disse guider

Minecraft Java er den udgave, de fleste servere kører, og den med rigtige plugins, mods og datapacks. Disse guider dækker en servers hele liv: at vælge en version og en servertype, tilføje plugins eller et modpack, redigere server.properties, give dig selv og dit team de rigtige rettigheder, uploade en verden og holde tingene hurtige, når folk først begynder at spille.

Er du helt ny, så læs guiden til de første skridt og versionsguiden, før du installerer noget, for den servertype du vælger afgør, hvad der senere kan og ikke kan indlæses. Paper, Purpur, Spigot, Fabric og Forge kan ikke bare byttes ud med hinanden, og at skifte mellem dem, efter du har bygget en liste af plugins eller mods, er det mest almindelige rod, man kan undgå.

• Kom ind på din Minecraft Java server

  Sådan finder du din servers adresse i panelet og tilføjer den i Minecraft Java klienten, og hvorfor det at få klientversionen til at passe normalt er løsningen, når du ikke kan komme ind.

• Serveren vises ikke i serverlisten

  De tre sædvanlige grunde til at en server ikke dukker op i din Minecraft serverliste, og hvordan du tjekker hver af dem: serveren er stadig ved at starte, IP eller port er forkert, eller din version passer ikke.

• Allowlist og whitelist forklaret

  Hvad allowlist (Bedrock) og whitelist (Java) gør, kommandoerne til at styre dem, og den klassiske fælde hvor du slår listen til uden navne på og dermed spærrer alle ude, også dig selv.

• Converting a Java world to Bedrock

  You can convert a Minecraft Java world to Bedrock using third party tools like Chunker, but it is lossy: terrain and builds usually survive, while entities and container contents often do not, and modded content will not convert at all. Here is the honest process.

• Fix "Address already in use" on a game server

  Two things want the same port and only one can have it. The usual causes are an old process that has not finished dying and a plugin quietly claiming a port of its own.

• Chunk loading, pre-generation and why exploring lags

  Generating new terrain is the heaviest single job your server ever does, which is why a fresh world lags while players explore and then settles down: pre-generating the map ahead of time and capping it with a world border removes the problem for good.
