Minecraft Snapshot 23w44a

In this week's Snapshot we're taking a break from new features to improve ones we've already added, including fixes to Commands and the ability to use Loot Tables with Decorated Pots.

Changes

• Copper Doors & Copper Trapdoors has updated textures

Technical Changes

• The Data Pack version is now 23

Data Pack Version 23

• Decorated Pots can now utilize loot tables and will read from the LootTable tag key
• Additional changes to command functions

Commands

tick

• The <time> parameter in the tick step command is now optional. The default value is 1

return

• return run will now always return
  • If there are no valid results from returned command, function containing return run will fail (i.e. success=0 and result=0)
• return run will now propagate success value together with results value (previously it always set success to 1)
• return run now also allows storing values - that means execute store ... run return run some_command will both store value and return it outside function
• New subcommand return fail is added to make whole function fail (i.e. return success=0 and result=0)

function

• If function <function tag> runs multiple functions in combination with return run, execution will stop after first return in any of the functions
• A single call to the function command will always have return when run with return run
  • For example, return run execute [split context] run function <some function with conditional return> will always return after processing the first context

execute if|unless function

• execute if|unless function will no longer always fail if all functions had no return
  • If there were no returns in called functions, if will fail and unless will pass
  • First return in any of called functions will return (for a single context)
