Paper configuration files

info

Many of our files have been comprehensively documented. If this is the case, they will offer a link to their page. If this is not the case, they offer a brief explanation to what they are.

logsⓘDescription:
This folder contains all the logs for the server. It compresses old logs into .gz files, but holds the most recent log as a .txt file.

Per-world configuration

One of the most powerful yet least understood features of the Paper configuration is setting configuration options per world. While you can not override every config option per world, everything stored within paper-world-defaults.yml can be.

Default values

Paper sets no per-world overrides out of the box, storing all default values in config/paper-world-defaults.yml. Everything in this file can be overridden per world but isn't by default. Changing something in paper-world-defaults.yml will change the value for all worlds where you have not manually overridden it.

Per-world values

To set a value for a specific world, edit paper-world.yml within the world folder. For example, if you wanted to disable spawn.keep-spawn-loaded for a world named resource, you would edit paper-world.yml within the resource folder like so:

_version: 28

spawn:
  keep-spawn-loaded: false

Nothing but _version is set in paper-world.yml configuration files by default. In order to override the default for an option, you must manually add it by copying from paper-world-defaults.yml.

Inheritance

All configuration not explicitly defined for a world is inherited from paper-world-defaults.yml. This means that there is no need to repeat yourself between the paper-world-defaults.yml and each individual paper-world.yml. You do not need to and should not copy the entire paper-world-default.yml file into each paper-world.yml file you want to modify. Only copy the exact value you want to change.

For a more complex real-world example: setting both different spawn-limits and keep-spawn-loaded in two worlds.

paper-world-defaults.yml
entities:
  spawning:
    spawn-limits:
      ambient: 70
      axolotls: 10
      creature: 15
      monster: 5
      underground_water_creature: 5
      water_ambient: 5
      water_creature: 20
spawn:
  keep-spawn-loaded: true

world_nether/paper-world.yml
entities:
  spawning:
    spawn-limits:
      monster: 90

resource_world/paper-world.yml
entities:
  spawning:
    spawn-limits:
      axolotls: 8
      creature: 15
      monster: 2
spawn:
  keep-spawn-loaded: false

This example demonstrates the concept of inheritance. For each world, this is the effective configuration which will be applied:

Configuration Key	world	world_nether	world_the_end	resource_world
`entities.spawning.spawn-limits.ambient`	`15`	`15`	`15`	`15`
`entities.spawning.spawn-limits.axolotls`	`5`	`5`	`5`	`8`
`entities.spawning.spawn-limits.creature`	`10`	`10`	`10`	`15`
`entities.spawning.spawn-limits.monster`	`70`	`90`	`70`	`2`
`entities.spawning.spawn-limits.underground_water_creature`	`5`	`5`	`5`	`5`
`entities.spawning.spawn-limits.water_ambient`	`20`	`20`	`20`	`20`
`entities.spawning.spawn-limits.water_creature`	`5`	`5`	`5`	`5`
`spawn.keep-spawn-loaded`	`true`	`true`	`true`	`false`

Notice that world_the_end/paper-world.yml was never modified. Because of this, it inherits all the configuration options from config/paper-world-defaults.yml. Additionally, keep-spawn-loaded was only disabled in resource_world/paper-world.yml because in config/paper-world-defaults.yml, keep-spawn-loaded is set to true.
