Properties

heightRange: NumberRange

Height range of the dimension.

This property can throw when used.

id: string

Identifier of the dimension.

Methods

  • Parameters

      The location of the explosion.

    • radius: number

      Radius, in blocks, of the explosion to create.

    • OptionalexplosionOptions: ExplosionOptions

      Additional configurable options for the explosion.

    Returns boolean

    This function can't be called in read-only mode.

    // Creates an explosion of radius 15 that does not break blocks
    import { DimensionLocation } from '@minecraft/server';

    function createExplosions(location: DimensionLocation) {
    // Creates an explosion of radius 15 that does not break blocks
    location.dimension.createExplosion(location, 15, { breaksBlocks: false });

    // Creates an explosion of radius 15 that does not cause fire
