API

  • Fixed bug where @minecraft/server-net was using the incorrect dedicated server configuration ID for a pack. Under ./config/<moduleID>/* is a pack's configuration for scripting. The server-net module was looking at the pack ID rather than the script module ID like all other modules.

    • It may only store up to 1KBytes of data per block entity
    • It (currently) does not carry over its data to the item resulting from mining or picking the block entity

    • It has a single boolean field dynamic_properties
    • It requires format version 1.26.20 and Experimental Upcoming Creator Features

    • system_behavior_packs and system_resource_packs
