Technical Updates

Experimental Features

API

Major breaking change to experimental JavaScript APIs:

All script modules have been renamed to follow a new convention.  

• mojang-gametest-> @minecraft/server-gametest
• mojang-minecraft-> @minecraft/server
• mojang-minecraft-ui-> @minecraft/server-ui
• mojang-minecraft-server-admin-> @minecraft/server-admin
• mojang-net-> @minecraft/server-net

For example, rather than using:

import * as mc from “mojang-minecraft”;

Use

import * as mc from “@minecraft/server”;

• Use of script eval()and Function() must be explicitly enabled in  json 
  • To do this, set script_evalin capabilities

"capabilities": [  "script_eval"]

• Root path for imports has changed; scripts/prefix are no longer allowed.
• For imports, use import "./source.js" or import "source.js"
• Deprecated use of import "scripts/source.js"

Actor Properties

• Fixed "bool_property" filters that didn't specify a "value"

Commands

• Temporarily disabled the rotation for the /summon command while a bug is worked on
• Fixed a rotation issue when a Command Block executes 'execute facing' and 'execute rotated' (MCPE-162256)
• Implemented the '/execute in' command
• Implemented the ‘/execute anchored <eyes|feet>’ command

General
