Creating a Datapack

Creating a DataPack

A DataPack in Kore represents a Minecraft datapack that contains custom game data and resources.

To create a DataPack, use the dataPack function:

dataPack("my_datapack") {
	// datapack code here
}.generate()

This will generate the datapack with the given name in the out folder by default. If generate() is not called, the datapack will not be generated.

Use generateZip() method to generate the datapack as a zip file.

Changing Output Folder

To change the output folder, use the path property:

dataPack("my_datapack") {
	path = Path("%appdata%/.minecraft/saves/my_world/datapacks")
}

Adding Icon

To add an icon to the datapack, use the iconPath property:

dataPack("my_datapack") {
	iconPath = Path("icon.png")
}

Configuration

See Configuration

Pack Metadata

The dataPack function generates a pack.mcmeta file containing metadata about the datapack.

Configure this metadata using the pack block:

dataPack("mydatapack") {
	pack {
		format = 15
		description = textComponent("My Datapack")
		supportedFormat(15..20)
	}
}

• format - The datapack format version.
• description - A text component for the datapack description.
• supportedFormats - The supported format versions.

Filters

Filters are used to filter out certain files from the datapack. For now, you can only filter out block files.

For example, to filter out all .txt files:

dataPack("my_datapack") {
	filter {
		blocks("stone*")
	}
}

This will filter out all block files that start with stone.

Content

The main content of the datapack is generated from the various builder functions like biome, lootTable, etc.

For example:

dataPack("my_datapack") {

	// ...

	recipes {
		craftingShaped("enchanted_golden_apple") {
			pattern(
				"GGG",
				"GAG",
				"GGG"
			)

			key("G", Items.GOLD_BLOCK)
			key("A", Items.APPLE)

			result(Items.ENCHANTED_GOLDEN_APPLE)
		}
	}
}

This demonstrates adding a custom recipe to the datapack.
