Apply DimensionType on Anvil Instance

[para-dise]

So I've been trying to figure out what the correct way of lighting up an anvil instance is, and I can't really figure it out.

InstanceManager instanceManager = MinecraftServer.getInstanceManager();

SwagCraftMap mapManager = new SwagCraftMap();
Instance lobby = mapManager.getMapInstance();

// Relight
LightingChunk.relight(lobby, lobby.getChunks());

// Create fullbright dimension
DimensionType fullbright = DimensionType.builder(NamespaceID.from("minestom:full_bright"))
                .ambientLight(2.0f)
                .build();
MinecraftServer.getDimensionTypeManager().addDimension(fullbright);

// Create the instance
InstanceContainer instanceContainer = instanceManager.createInstanceContainer(fullbright);

GlobalEventHandler globalEventHandler = MinecraftServer.getGlobalEventHandler();
globalEventHandler.addListener(AsyncPlayerConfigurationEvent.class, event -> {
    final Player player = event.getPlayer();

    event.setSpawningInstance(lobby);
});

Calling LightingChunk#relight seems to have no effect, unless its relighting it using vanilla values, and I'm not sure how I can set the Anvil instance's DimensionType to the one I just created...

Turns out the solution was

DimensionType fullbright = DimensionType.builder(NamespaceID.from("swagcraft:void"))
                .ambientLight(2.0f)
                .build();

        MinecraftServer.getDimensionTypeManager().addDimension(fullbright);

        return MinecraftServer.getInstanceManager().createInstanceContainer(
                fullbright,
                new AnvilLoader(
                    "maps/" + game.getName()
                )
        );
