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);

/**
 * Get the blocks from player surroundings and set to obsidian
 */
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;
