Minecraft - 1.20.40 (Bedrock)

Updated Add-On Template Packs​

  • Updated Add-On templates for 1.20.40 with new resources, behaviors, and documentation are available to download at aka.ms/MCAddonPacks

Stability and Performance​

  • The Sounds definition file sound_definitions.json will no longer crash the game if the wrong json type is used for a specific sound definition (MCPE-168913)

Commands​

  • Re-entering a world no longer breaks command autocomplete after a command using "@e[type=item]" was used (MCPE-164734)
  • The /damage command with the "override" cause now causes damage through post hit invulnerability (MCPE-160290)
  • The recipe command color has been changed to white instead of blue (MCPE-173362)

Mobs​

  • Added a new “query.is_in_lava” Query Function to Molang, to know if a mob is currently in Lava

Molang​

  • Molang updated to version 1.20.40 which replaces "block_property" and "has_block_property" with "block_state" and "has_block_state"
    • This is a Molang Versioned Change that only takes effect for Molang expressions in packs that use a min_engine_version of 1.20.40 or higher

Trade Tables​

  • Trade items now have a "filters" property to determine if a trade should be considered
  • Trade items no longer support the "biome" property to check villager biome types, the "is_mark_variant" filter can be used in the "filters" property instead to check the villager biome type

  • “behavior.timer_flag 2”: Fires an event when this behavior starts, then waits for a duration before stopping. When stopping due to that timeout or due to being interrupted by another behavior, fires another event. query.timer_flag_2 will return 1.0 on both the client and server when this behavior is running, and 0.0 otherwise

  • “behavior.timer_flag 3”: Fires an event when this behavior starts, then waits for a duration before stopping.
