Class BlockPermutation

Contains the combination of type BlockType and properties (also sometimes called block state) which describe a block (but does not belong to a specific Block).

Example: createTranslatedSign.ts

// A function the creates a sign at the specified location with the specified text
import { DimensionLocation, BlockPermutation, BlockComponentTypes } from '@minecraft/server';
import { MinecraftBlockTypes } from '@minecraft/vanilla-data';

function createSignAt(location: DimensionLocation) {
    const signBlock = location.dimension.getBlock(location);

    if (!signBlock) {
        console.warn('Could not find a block at specified location.');
        return;
    }

    const signPerm = BlockPermutation.resolve(MinecraftBlockTypes.StandingSign, { ground_sign_direction: 8 });
    signBlock.setPermutation(signPerm); // Update block to be a sign

    // Update the sign block's text
    // with "Steve's Head"
    const signComponent = signBlock.getComponent(BlockComponentTypes.Sign);
    if (signComponent) {
        signComponent.setText({ translate: 'item.skull.player.name', with: ['Steve'] });
    }
}

Properties

Readonlytype

type: BlockType

Remarks

The BlockType that the permutation has.

Methods

getAllStates

  • getAllStates(): Record<string, string | number | boolean>

    Returns Record<string, string | number | boolean>

    Returns the list of all of the block states that the permutation has.

    Remarks

    Returns all available block states associated with this block.

getItemStack

  • getItemStack(amount?: number): ItemStack

    Parameters

    • Optionalamount: number

      Number of instances of this block to place in the prototype item stack.

    Returns ItemStack

    Remarks

    Retrieves a prototype item stack based on this block permutation that can be used with item Container/ContainerSlot APIs.

getState

  • getState(stateName: string): string | number | boolean

    Parameters

    • stateName: string

      Name of the block state who's value is to be returned.

    Returns string | number | boolean

    Returns the state if the permutation has it, else undefined.

    Remarks

    Gets a state for the permutation.

getTags

  • getTags(): string[]
    Beta

    Returns string[]

    Remarks

    Creates a copy of the permutation.

hasTag

  • hasTag(tag: string): boolean
    Beta

    Parameters

    • tag: string

    Returns boolean

    Returns true if the permutation has the tag, else false.

    Remarks

    Checks to see if the permutation has a specific tag.

    Example: check_block_tags.js

    import { world } from "@minecraft/server";

    // Fetch the block
    const block = world.getDimension("overworld").getBlock({ x: 1, y: 2, z: 3 });
    const blockPerm = block.getPermutation();

    console.log(`Block is dirt: ${blockPerm.hasTag("dirt")}`);
    console.log(`Block is wood: ${blockPerm.hasTag("wood")}`);
    console.log(`Block is stone: ${blockPerm.hasTag("stone")}`);

matches

  • matches(
        blockName: string,
        states?: Record<string, string | number | boolean>,
    ): boolean

    Parameters

    • blockName: string

      An optional set of states to compare against.

    • Optionalstates: Record<string, string | number | boolean>

    Returns boolean

    Remarks

    Returns a boolean whether a specified permutation matches this permutation. If states is not specified, matches checks against the set of types more broadly.

withState

  • withState(name: string, value: string | number | boolean): BlockPermutation

    Parameters

    • name: string

      Identifier of the block property.

    • value: string | number | boolean

      Value of the block property.

    Returns BlockPermutation

    Remarks

    Returns a derived BlockPermutation with a specific property set.

    Throws

    This function can throw errors.

Staticresolve

  • resolve(
        blockName: string,
        states?: Record<string, string | number | boolean>,
    ): BlockPermutation

    Parameters

    • blockName: string

      Identifier of the block to check.

    • Optionalstates: Record<string, string | number | boolean>

    Returns BlockPermutation

    Remarks

    Given a type identifier and an optional set of properties, will return a BlockPermutation object that is usable in other block APIs (e.g., block.setPermutation)

    Throws

    This function can throw errors.

    Example: addBlockColorCube.ts

    import { DimensionLocation, BlockPermutation } from '@minecraft/server';
    import { MinecraftBlockTypes } from '@minecraft/vanilla-data';

    const allWoolBlocks: string[] = [
        MinecraftBlockTypes.WhiteWool,
        MinecraftBlockTypes.OrangeWool,
        MinecraftBlockTypes.MagentaWool,
        MinecraftBlockTypes.LightBlueWool,
        MinecraftBlockTypes.YellowWool,
        MinecraftBlockTypes.LimeWool,
        MinecraftBlockTypes.PinkWool,
        MinecraftBlockTypes.GrayWool,
        MinecraftBlockTypes.LightGrayWool,
        MinecraftBlockTypes.CyanWool,
        MinecraftBlockTypes.PurpleWool,
        MinecraftBlockTypes.BlueWool,
        MinecraftBlockTypes.BrownWool,
        MinecraftBlockTypes.GreenWool,
        MinecraftBlockTypes.RedWool,
        MinecraftBlockTypes.BlackWool,
    ];

    const cubeDim = 7;

    function placeRainbowCube(location: DimensionLocation) {
        let colorIndex = 0;
        for (let x = 0; x <= cubeDim; x++) {
            for (let y = 0; y <= cubeDim; y++) {
                for (let z = 0; z <= cubeDim; z++) {
                    colorIndex++;
                    location.dimension
                        .getBlock({ x: location.x + x, y: location.y + y, z: location.z + z })
                        ?.setPermutation(BlockPermutation.resolve(allWoolBlocks[colorIndex % allWoolBlocks.length]));
                }
            }
