Quickstart

1. Place the jar in plugins/ (Paper) or mods/ (Sponge).
2. Start the server.
3. Try it:

/stone location set home     # save the current position
/nav home                    # navigate back to it

Cobblestone runs an A* search over the live world and renders the route as a particle trail.

For admins

• Core: Personal and global saved locations, death locations, players, worlds, and learned nether and End portal links.
• Towny: Towns, outposts, and plots as destinations; /town spawn and /nation spawn as route steps; build protection.
• EssentialsX: Homes and spawn as destinations; /home and /spawn as route steps.
• Citizens, BetonQuest, BeautyQuests, Quests, Typewriter: NPCs and quest objectives as destinations, with optional automatic trips.

Integrations are distributed as separate plugins.

Player permissions default to allow; admin permissions default to op.

Node	Default	Grants
cobblestone.navigate	everyone	/navigate, /cobblestone trips, /cobblestone cancel
cobblestone.location	everyone	personal locations
cobblestone.navigator	everyone	non-default navigators
cobblestone.admin.*	op	reload, portals, loglevel, -global locations

Each destination also has a node derived from its address:

/lp group default permission set cobblestone.navigate.towny.town.riverwood.* false

For developers

repositories { mavenCentral() }

dependencies {
    // Paper
    compileOnly("org.cobblestonemc:paper-plugin-api:0.1.0")
    // Sponge
    // compileOnly("org.cobblestonemc:sponge-12-plugin-api:0.1.0")
}

Register destinations under your plugin's name:

CobblestonePaperApi.registrar().registerDestinations(this, player ->
    DestinationTree.builder()
        .leaf("market", () -> Destination.at(marketLocation(), "Market"))
        .build());

Start a trip:

CobblestonePaperApi.tripService()
    .navigate(player, objective, NavigatorSettings.defaults(), "Lost Lantern");

Add transitions and restrict breaking:

CobblestoneCoreApi.registrar().register(this, new SearchModificationService() {
  @Override
  public CompletableFuture<List<Transition>> computeTransitions(Player player) {
    return CompletableFuture.completedFuture(
        List.of(Transition.command(player, market, 3.0, "/warp market")));
  }

  @Override
  public BreakChecker computeBreakChecker(Player player) {
    return (p, location, block) ->
        CompletableFuture.completedFuture(claims.mayBreak(p, location));
  }
});

Custom navigators and direct searches are also supported. See project/examples/paper-warps for a complete example.
