global.conf

Global Configuration

The global.conf file contains the global configuration settings for Sponge. This file is created in the config/sponge directory in your server folder. Many of these properties can be also overridden per-world or per-dimension type by using the config files in the subfolders of config/worlds.

Below is a list of available config settings and their comments inside the global.conf file. Note that certain sections will not be filled immediately, and may optionally be added to the file when the server encounters them. There’s also full example of an unmodified global.conf file at the bottom of this page, below the following list:

Note

The following section headings refer to the path within the configuration (and the corresponding simple class name). Each of the entries in a section refers to a configurable property in the associated class. The Type information refers to the section/class that describes the nested configuration structure.

broken-mods (BrokenMod)

Stopgap measures for dealing with broken mods

  • broken-network-handler-mods

    A list of mod ids that have broken network handlers (they interact with the game from a Netty handler thread). All network handlers from a forcibly scheduled to run on the main thread. Note that this setting should be considered a last resort, and should only be used as a stopgap measure while waiting for a mod to properly fix the issue.

Type: List<String>

bungeecord (BungeeCord)

  • ip-forwarding

    If true, allows BungeeCord to forward IP address, UUID, and Game Profile to this server.

Type: boolean
Default: false

cause-tracker (PhaseTracker)

Type: Map<String, Boolean>

  • capture-async-spawning-entities

    If set to true, when a mod or plugin attempts to spawn an entity off the main server thread, Sponge will automatically capture said entity to spawn it properly on the main server thread. The catch to this is that some mods are not considering the consequences of spawning an entity off the server thread, and are unaware of potential race conditions they may cause. If this is set to false, Sponge will politely ignore the entity being spawned, and emit a warning about said spawn anyways.

Type: boolean
Default: true

  • generate-stacktrace-per-phase

    If true, more thorough debugging for PhaseStates such that a StackTrace is created every time a PhaseState switches, allowing for more fine grained troubleshooting in the cases of runaway phase states. Note that this is not extremely performant and may have some associated costs with generating the stack traces constantly.

Type: boolean
Default: false

  • max-block-processing-depth

    The maximum number of times to recursively process transactions in a single phase. Some mods may interact badly with Sponge’s block capturing system, causing Sponge to end up capturing block transactions every time it tries to process an existing batch. Due to the recursive nature of the depth-first processing that Sponge uses to handle block transactions, this can result in a stack overflow, which causes us to lose all infomration about the original cause of the issue. To prevent a stack overflow, Sponge tracks the current processing depth, and aborts processing when it exceeds this threshold. The default value should almost always work properly - it’s unlikely you’ll ever have to change it.

Type: int
Default: 1000

  • maximum-printed-runaway-counts

    If verbose is not enabled, this restricts the amount of runaway phase state printouts, usually happens on a server where a PhaseState is not completing. Although rare, it should never happen, but when it does, sometimes it can continuously print more and more. This attempts to placate that while a fix can be worked on to resolve the runaway. If verbose is enabled, they will always print.

Type: int
Default: 3

  • report-null-source-blocks-on-neighbor-notifications

    If true, when a mod attempts to perform a neighbor notification on a block, some mods do not know to perform a null check on the source block of their TileEntity. This usually goes by unnoticed by other mods, because they may perform == instance equality checks instead of calling methods on the potentially null Block, but Sponge uses the block to build information to help tracking. This has caused issues in the past. Generally, this can be useful for leaving true so a proper report is generated once for your server, and can be reported to the offending mod author. This is false by default in SpongeVanilla. Review the following links for more info: https://gist.github.com/gabizou/ad570dc09dfed259cac9d74284e78e8b https://github.com/SpongePowered/SpongeForge/issues/2787

Type: boolean
Default: true

  • resync-commands-from-async

    If set to true, when a mod or plugin attempts to submit a command asynchronously, Sponge will automatically capture said command and submit it for processing on the server thread. The catch to this is that some mods are performing these commands in vanilla without considering the possible consequences of such commands affecting any thread-unsafe parts of Minecraft, such as worlds, block edits, entity spawns, etc. If this is set to false, Sponge will politely ignore the command being executed, and emit a warning about said command anyways.

Type: boolean
Default: true

  • verbose

    If true, the phase tracker will print out when there are too many phases being entered, usually considered as an issue of phase re-entrance and indicates an unexpected issue of tracking phases not to complete. If this is not reported yet, please report to Sponge. If it has been reported, you may disable this.

Type: boolean
Default: true

  • verbose-errors

    If true, the phase tracker will dump extra information about the current phases when certain non-PhaseTracker related exceptions occur. This is usually not necessary, as the information in the exception itself can normally be used to determine the cause of the issue

Type: boolean
Default: false

commands (Commands)

  • aliases

    Command aliases will resolve conflicts when multiple plugins request a specific command, Correct syntax is <unqualified command>=<plugin name> e.g. sethome=homeplugin

Type: Map<String, String>

  • command-hiding

    Defines how Sponge should act when a user tries to access a command they do not have permission for

Type: CommandsHidden

  • enforce-permission-checks-on-non-sponge-commands

    Some mods may not trigger a permission check when running their command. Setting this to true will enforce a check of the Sponge provided permission (<modid>.command.<commandname>). Note that setting this to true may cause some commands that are generally accessible to all to require a permission to run. Setting this to true will enable greater control over whether a command will appear in tab completion and Sponge’s help command. If you are not using a permissions plugin, it is highly recommended that this is set to false (as it is by default).

Type: boolean
Default: false

  • multi-world-patches

    Patches the specified commands to respect the world of the sender instead of applying the changes on the all worlds.

Type: Map<String, Boolean>

commands.command-hiding (CommandsHidden)

Defines how Sponge should act when a user tries to access a command they do not have permission for

  • hide-on-discovery-attempt

    If this is true, when a user tries to tab complete a command, or use /sponge which or /sponge:help this prevents commands a user does not have permission for from being completed. Note that some commands may not show up during tab complete if a user does not have permission regardless of this setting.

Type: boolean
Default: true

  • hide-on-execution-attempt

    If this is true, when a user tries to use a command they don’t have permission for, Sponge will act as if the command doesn’t exist, rather than showing a no permissions message.

Type: boolean
Default: false

debug (Debug)

  • concurrent-chunk-map-checks

    Detect and prevent parts of PlayerChunkMap being called off the main thread. This may decrease sever preformance, so you should only enable it when debugging a specific issue.

Type: boolean
Default: true

general (GlobalGeneral)

  • config-dir

    The directory for Sponge plugin configurations, relative to the execution root or specified as an absolute path. Note that the default: ${CANONICAL_GAME_DIR}/config is going to use the config directory in the root game directory. If you wish for plugin configs to reside within a child of the configuration directory, change the value to, for example, ${CANONICAL_CONFIG_DIR}/sponge/plugins.

    Note: It is not recommended to set this to ${CANONICAL_CONFIG_DIR}/sponge, as there is a possibility that plugin configurations can conflict the Sponge core configurations.

    Allows configuring Vanilla movement and speed checks

Type: boolean
Default: false

  • optimizations
Type: boolean
Default: true

  • realtime

    Use real (wall) time instead of ticks as much as possible

    Runs lighting updates asynchronously.

Type: AsyncLighting

  • cache-tameable-owners

    Caches tameable entities owners to avoid constant lookups against data watchers. If mods cause issues, disable this.

Type: boolean
Default: true

  • disable-failing-deserialization-log-spam

    Occasionally, some built in advancements, recipes, etc. can fail to deserialize properly which ends up potentially spamming the server log and the original provider of the failing content is not able to fix. This provides an option to suppress the exceptions printing out in the log.

Type: boolean
Default: true

  • drops-pre-merge

    If true, block item drops are pre-processed to avoid having to spawn extra entities that will be merged post spawning. Usually, Sponge is smart enough to determine when to attempt an item pre-merge and when not to, however, in certain cases, some mods rely on items not being pre-merged and actually spawned, in which case, the items will flow right through without being merged.

Type: boolean
Default: true

  • eigen-redstone

    Uses theosib’s redstone algorithms to completely overhaul the way redstone works.

Type: EigenRedstone

  • enchantment-helper-leak-fix

    If true, provides a fix for possible leaks through Minecraft’s enchantment helper code that can leak entity and world references without much interaction Forge native (so when running SpongeForge implementation) has a similar patch, but Sponge’s patch works a little harder at it, but Vanilla (SpongeVanilla implementation) does NOT have any of the patch, leading to the recommendation that this patch is enabled for sure when using SpongeVanilla implementation. See https://bugs.mojang.com/browse/MC-128547 for more information.

Type: boolean
Default: true

  • faster-thread-checks

    If true, allows for Sponge to make better assumptinos on single threaded operations with relation to various checks for server threaded operations. This is default to true due to Sponge being able to precisely inject when the server thread is available. This should make an already fast operation much faster for better thread checks to ensure stability of sponge’s systems.

Type: boolean
Default: true

  • map-optimization

    If true, re-writes the incredibly inefficient Vanilla Map code. This yields enormous performance enhancements when using many maps, but has a tiny chance of breaking mods that invasively modify Vanilla.It is strongly reccomended to keep this on, unless explicitly advised otherwise by a Sponge developer

Type: boolean
Default: true

  • optimize-hoppers

    Based on Aikar’s optimizationo of Hoppers, setting this to true will allow for hoppers to save performing server -> client updates when transferring items. Because hoppers can transfer items multiple times per tick, these updates can get costly on the server, with little to no benefit to the client. Because of the nature of the change, the default will be false due to the inability to pre-emptively foretell whether mod compatibility will fail with these changes or not. Refer to: https://github.com/PaperMC/Paper/blob/8175ec916f31dcd130fe0884fe46bdc187d829aa/Spigot-Server-Patches/0269-Optimize-Hoppers.patch for more details.

Type: boolean
Default: false

  • panda-redstone

    If true, uses Panda4494’s redstone implementation which improves performance. See https://bugs.mojang.com/browse/MC-11193 for more information.

    Note: This optimization has a few issues which are explained in the bug report. We strongly recommend using eigen redstone over this implementation as this will be removed in a future release.

Type: boolean
Default: false

  • structure-saving

    Handles structures that are saved to disk. Certain structures can take up large amounts of disk space for very large maps and the data for these structures is only needed while the world around them is generating. Disabling saving of these structures can save disk space and time during saves if your world is already fully generated.

    Warning: disabling structure saving will break the vanilla locate command.

Type: StructureSave

  • use-active-chunks-for-collisions

    Vanilla performs a lot of is area loaded checks during entity collision calculations with blocks, and because these calculations require fetching the chunks to see if they are loaded, before getting the block states from those chunks, there can be some small performance increase by checking the entity’s owned active chunk it may currently reside in. Essentially, instead of asking the world if those chunks are loaded, the entity would know whether it’s chunks are loaded and that neighbor’s chunks are loaded.

Type: boolean
Default: false

optimizations.async-lighting (AsyncLighting)

Runs lighting updates asynchronously.

  • enabled

    If true, lighting updates are run asynchronously.

Type: boolean
Default: true

Default: false

  • vanilla-decrement

    If true, restores the vanilla algorithm for computing wire power levels when powering off.

Type: boolean
Default: false

  • vanilla-search

    If true, restores the vanilla algorithm for propagating redstone wire changes.

Type: boolean
Default: false

optimizations.structure-saving (StructureSave)

Handles structures that are saved to disk. Certain structures can take up large amounts of disk space for very large maps and the data for these structures is only needed while the world around them is generating. Disabling saving of these structures can save disk space and time during saves if your world is already fully generated.

Warning: disabling structure saving will break the vanilla locate command.

  • auto-populate

    If true, newly discovered structures will be added to this config with a default value of true. This is useful for finding out potentially what structures are being saved from various mods, and allowing those structures to be selectively disabled.

Type: boolean
Default: false

  • enabled

    If false, disables the modification to prevent certain structures from saving to the world’s data folder. If you wish to prevent certain structures from saving, leave this enabled=true. When true, the modification allows for specific named structures to NOT be saved to disk. Examples of some structures that are costly and somewhat irrelivent is mineshafts, as they build several structures and save, even after finished generating.

Type: boolean
Default: false

  • mods

    Per-mod overrides. Refer to the minecraft default mod for example.

Type: Map<String, StructureMod>

optimizations.structure-saving.mods (StructureMod)

Per-mod overrides. Refer to the minecraft default mod for example.

  • enabled

    If false, this mod will never save its structures. This may break some mod functionalities when requesting to locate their structures in a World.

  • auto-save-interval

    The auto-save tick interval used to save all loaded chunks in a world. Set to 0 to disable.

    Note: 20 ticks is equivalent to 1 second.

Type: int
Default: 900

  • chunk-gc-load-threshold

    The number of newly loaded chunks before triggering a forced cleanup.

    Note: When triggered, the loaded chunk threshold will reset and start incrementing. Disabled by default.

Type: int
Default: 0

  • chunk-gc-tick-interval

    The tick interval used to cleanup all inactive chunks that have leaked in a world. Set to 0 to disable which restores vanilla handling.

Type: int
Default: 600

  • chunk-unload-delay

    The number of seconds to delay a chunk unload once marked inactive.

    Note: This gets reset if the chunk becomes active again.

Type: int
Default: 15

  • deny-chunk-requests

    If true, any request for a chunk not currently loaded will be denied (exceptions apply for things like world gen and player movement).

    Warning: As this is an experimental setting for performance gain, if you encounter any issues then we recommend disabling it.

Type: boolean
Default: true

  • gameprofile-lookup-task-interval

    The interval, in seconds, used by the GameProfileQueryTask to process queued GameProfile requests.

    Note: This setting should be raised if you experience the following error: The client has sent too many requests within a certain amount of time. Finally, if set to 0 or less, the default interval will be used.

Type: int
Default: 4

  • generate-spawn-on-load

    If true, this world will generate its spawn the moment its loaded.

Type: Boolean
Default: false

  • invalid-lookup-uuids

    The list of uuid’s that should never perform a lookup against Mojang’s session server.

    Note: If you are using SpongeForge, make sure to enter any mod fake player’s UUID to this list.

Type: List<UUID>

  • item-merge-radius

    The defined merge radius for Item entities such that when two items are within the defined radius of each other, they will attempt to merge. Usually, the default radius is set to 0.5 in Vanilla, however, for performance reasons 2.5 is generally acceptable.

    Note: Increasing the radius higher will likely cause performance degradation with larger amount of items as they attempt to merge and search nearby areas for more items. Setting to a negative value is not supported!

Type: double
Default: 2.5

  • keep-spawn-loaded

    If true, this worlds spawn will remain loaded with no players.

Type: Boolean
Default: true

  • leaf-decay

    If true, natural leaf decay is allowed.

Type: boolean
Default: true

  • load-on-startup

    If true, this world will load on startup.

Type: Boolean
Default: false

  • max-chunk-unloads-per-tick

    The maximum number of queued unloaded chunks that will be unloaded in a single tick.

    Note: With the chunk gc enabled, this setting only applies to the ticks where the gc runs (controlled by chunk-gc-tick-interval)

    Note: If the maximum unloads is too low, too many chunks may remain loaded on the world and increases the chance for a drop in tps.

Type: int
Default: 100

  • mob-spawn-range

    Specifies the radius (in chunks) of where creatures will spawn. This value is capped to the current view distance setting in server.properties

Type: int
Default: 4

  • portal-agents

    A list of all detected portal agents used in this world. In order to override, change the target world name to any other valid world.

    Note: If world is not found, it will fallback to default.

Type: Map<String, String>

  • pvp-enabled

    If true, this world will allow PVP combat.

Type: boolean
Default: true

  • view-distance

    Override world distance per world/dimension The value must be greater than or equal to 3 and less than or equal to 32 The server-wide view distance will be used when the value is -1.

Type: int
Default: -1

  • weather-ice-and-snow

    If true, natural formation of ice and snow in supported biomes will be allowed.

Type: boolean
Default: true

  • weather-thunder

    If true, thunderstorms will be initiated in supported biomes.

Type: boolean
Default: true
