Class Block

Represents a block in a dimension. A block represents a unique X, Y, and Z within a dimension and get/sets the state of the block at that location. This type was significantly updated in version 1.17.10.21.

Example: createWall.ts

import {
    Vector3Utils,
    VECTOR3_NORTH,
    VECTOR3_WEST,
    VECTOR3_EAST,
    VECTOR3_SOUTH,
} from "@minecraft/math";
import { Entity } from "@minecraft/server";
import { MinecraftBlockTypes } from "@minecraft/vanilla-data";

const VECTOR3_NORTHWEST = Vector3Utils.add(VECTOR3_NORTH, VECTOR3_WEST);
const VECTOR3_NORTHEAST = Vector3Utils.add(VECTOR3_NORTH, VECTOR3_EAST);
const VECTOR3_SOUTHWEST = Vector3Utils.add(VECTOR3_SOUTH, VECTOR3_WEST);
const VECTOR3_SOUTHEAST = Vector3Utils.add(VECTOR3_SOUTH, VECTOR3_EAST);

export function createWallAroundEntity(entity: Entity) {
    const location = entity.location;
    const block = entity.dimension.getBlock(location);
    if (!block) return;
    const blockNorth = block.north();
    const blockSouth = block.south();
    const blockEast = block.east();
    const blockWest = block.west();
    const blockNorthWest = block.offset(VECTOR3_NORTHWEST);
    const blockNorthEast = block.offset(VECTOR3_NORTHEAST);
    const blockSouthWest = block.offset(VECTOR3_SOUTHWEST);
    const blockSouthEast = block.offset(VECTOR3_SOUTHEAST);
    const blocks = [
        blockNorth,
        blockSouth,
        blockEast,
        blockWest,
        blockNorthWest,
        blockNorthEast,
        blockSouthWest,
        blockSouthEast,
    ];
    // Check if the player have contact with cactus or sweet berry bush
    for (const block of blocks) {
        if (!block) continue;
        block.setType(MinecraftBlockTypes.Obsidian);
    }

Properties

`Readonly`dimension

dimension: Dimension

Remarks

Returns the dimension that the block is within.

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

// Block explodes when player break block

    event.block.dimension.createExplosion(event.block.location, 1);
});

isAir: boolean

Remarks

Returns true if this block is an air block (i.e., empty space).

Throws

This property can throw when used.
