Bedrock Ore Veins

While not enabled by default, GTCEu Modern contains bedrock ore veins and bedrock ore miners.

To enable this feature, you need to enable the config option Machines -> doBedrockOres and restart your game.

No recipes by default

The various tiers of bedrock ore miners don't have any recipes by default. It is up to modpack developers to create crafting recipes for these machines.

Adding Bedrock Veins

By default, the mod doesn't include any bedrock ore veins. You can add them in either KubeJS or Java using one of the following:

JavaScriptJava

Using the bedrockOreVeins server event:

GTCEuServerEvents.bedrockOreVeins(event => {
    event.add('kubejs:overworld_bedrock_ore_vein_iron', vein => {
        vein.weight(100)
            .size(3) // (1)
            .yield(10, 20)
            .material(GTMaterials.Goethite, 5) // (2)
            .material(GTMaterials.Limonite, 2)
            .material(GTMaterials.Hematite, 2)
            .material(GTMaterials.Malachite, 1)
            .dimensions('minecraft:overworld')
    })
})

1. The diameter of the bedrock vein in chunks
2. The second parameter defines the chance of each material being mined on each cycle

In Java, .dimensions() only accepts a Set<ResourceKey<Level>>. For example, this is how you would assign the overworld a variable:

public static final Set<ResourceKey<Level>> DIM_OVERWORLD = Set.of(Level.OVERWORLD);

To have multiple dimensions in the same set, simply add more ResourceKey<Level> instances into the set itself. Here's an example for all vanilla dimensions:

public static final Set<ResourceKey<Level>> DIM_ALL = Set.of(Level.OVERWORLD, Level.NETHER, Level.END);

You can define this in any class you want (including the one with the bedrock ore vein definitions themselves), as long as you're able to reference it in the class where you're defining the bedrock ore veins.
With this done, you can reference said variables in the BedrockOreDefinition builder. Let's use DIM_OVERWORLD in this example.

ExampleBedrockOreVeins.java

pubic class ExampleBedrockOreVeins {
    public static void init() {}

    public static final Set<ResourceKey<Level>> DIM_OVERWORLD = Set.of(Level.OVERWORLD);

    public static final BedrockOreDefinition OVERWORLD_BEDROCK_ORE_VEIN_IRON = BedrockOreDefinition.builder(ExampleMod.id("overworld_bedrock_ore_vein_iron"))
            .weight(100)
            .size(3) // (1)
            .yield(10, 20)
            .materials(List.of(
                new WeightedMaterial(Goethite, 5), // (2)
                new WeightedMaterial(Limonite, 2),
                new WeightedMaterial(Hematite, 2),
                new WeightedMaterial(Gold, 1)
            ))
            .dimensions(DIM_OVERWORLD)
            .register();
}

1. The diameter of the bedrock vein in chunks
2. The second parameter defines the chance of each material being mined on each cycle

As the last step, you need to actually enable the registration of the veins in your class implementing IGTAddon.

ExampleModGTAddon.java

@GTAddon
public class ExampleModGTAddon implements IGTAddon {
    // ...
    @Override
    public void registerBedrockOreVeins() {
        ExampleBedrockOreVeins.init();
    }
    // ...
}
