Code of Copper

[0.3.2] - 2024-04-27

Update to 1.20.5

Changed

• The datapack now requires 1.20.5

Fixed

[0.3.1] - 2024-01-29

The big split

Added

• The background of the text above the golem is now coloured based on its oxidisation level

Changed

  • It is now its own separate pack
  • This datapack uses its API to run programs and control the golems

• The experimental API
  • This is now part of the GolemScript API

[0.3.0-alpha-1] - 2023-12-24

Added

• Experimental, unstable support for extensions.
  • This should only impact datapack developers wishing to add their own functions.

• The entire interpreter was re-written from the ground up
  • It should now be far more reliable going forwards
• Place now takes a resource rather than a slot number

Fixed
