About Open Parties and Claims
From ModrinthAdds the ability to claim chunks and make player parties, integrates with Xaero's Minimap and World Map
_The mod is currently in Beta!_
This mod adds the ability to claim and to forceload world chunks, as well as create and manage player parties. It also gives server owners powerful controls over their players' usage of the mod's features.
By default, claims are owned by individual players who are able to make protection exceptions based on party relations or custom player groups. Server owners can also turn on party-owned claims which is explained in the FAQ below.
The mod's API allows other mods or plugins to easily interact with the parties and the chunk claims, both on the server and the client side. The mod already integrates with Xaero's Minimap and World Map mods. Make sure to update them to the latest versions.
The API of the mod allows the implementation of player permission systems to be used by the mod for some permission nodes (e.g. for having rank-based claim limits), with Prometheus, FTB Ranks, LuckPerms and the Forge/Fabric permission APIs having built-in support. It also allows the implementation of party systems to be used by claims alongside or instead of the default party system, with Argonauts and FTB Teams having built-in support. The default party system or claims can be disabled completely in the main config file.
Commands (since 0.30.0):
/opac … - player config commands (server claims, wilderness and expired claims also have a "player config")
/oclaims … - everything claim-related
/oparties … - everything party-related
/opm - shortcut for the party chat
Key Bindings:
' - open the mod UI. Can be changed in the controls menu.
Configs:
[world directory]/serverconfig/openpartiesandclaims-server.toml - the usual location of the main config file. Make sure to shut down the server before editing it, or the server might overwrite all your changes.
[server directory]/config/openpartiesandclaims-server.toml - sometimes the location of the main config file on Fabric/Quilt.
[world directory]/serverconfig/openpartiesandclaims-... - some global "player configs", although all of them can be accessed in game through the UI
Permission Nodes (since 0.33.0):
The permission nodes that this mod looks up for various reasons are not just static paths. They can be configured in the main config file, e.g. option "maxPlayerClaimsPermission". The used permission system (FTB Ranks, LuckPerms etc) can be configured with the "permissionSystem" option in the main config file.
If you or the modpack you are using have not changed the permission nodes, then the permission node paths should be the following:
- "xaero.pac\_max\_player\_groups" - The meta value permission that should override the default "maxPlayerGroups" option value in the main config.
- "xaero.pac\_player\_group\_space" - The meta value permission that should override the default "playerGroupSpace" option value in the main config.
- "xaero.pac\_max\_claims" - The meta value permission that should override the default "maxPlayerClaims" option value in the main config.
- "xaero.pac\_max\_forceloads" - The meta value permission that should override the default "maxPlayerClaimForceloads" option value in the main config.
- "xaero.pac\_max\_claiming\_anchors" - The meta value permission that should override the default "maxPlayerClaimingAnchors" option value in the main config.
- "xaero.pac\_claiming\_anchor\_range" - The meta value permission that should override the default "claimingAnchorRange" option value in the main config.
- "xaero.pac\_server\_claims" - The permission that gives non-OP players the ability to make server claims and enable server claim mode.
- "xaero.pac\_claims\_moderator\_mode" - The permission that gives non-OP players the ability to enable claim moderator mode which enables them to see player owners of party-owned claims.
- "xaero.pac\_claims\_admin\_mode" - The permission that gives non-OP players the ability to enable claim admin mode which, in addition to moderator mode features, gives them the ability to circumvent the vast majority of claim-related limitations, e.g. protection, max claiming distance, inability to claim a chunk.
- "xaero.pac\_claims\_impersonation" - The permission that gives non-OP players the ability to impersonate other players when performing claim-related actions.
- "xaero.pac\_claims\_teleport" - The permission that gives non-OP players the ability to teleport to any player's claims.
- "xaero.pac\_parties\_admin\_mode" - The permission that gives non-OP players the ability to enable parties admin mode which lets them see party chat messages for all built-in party system parties.
- "xaero.pac\_parties\_impersonation" - The permission that gives non-OP players the ability to impersonate other players when performing party-related commands.
- "xaero.pac\_claiming\_paused" - The permission that pauses claiming for the player who has it.
- "xaero.pac\_new\_forceloads\_paused" - The permission that pauses the ability to mark new chunks for forceloading for the player who has it.
FAQ
1) How do I configure the mod on my server?
The mod is mainly configured through the main config file at _[world directory]/serverconfig/openpartiesandclaims-server.toml_, or sometimes _[server directory]/config/openpartiesandclaims-server.toml_ on Fabric/Quilt, while the server isn't running. Server claim, expired claim and wilderness configs, as well as the default player config, can be edited by OPs in-game with the UI (check your key bindings). Normal players can configure their own player config with the same UI. If the mod isn't installed on the client side, then you can use the player config chat commands instead.
