Predicator

Data-driven means to add restrictions on what players can or cannot do.

Register tags and matching predicates, to prevent your players from doing what you don't want them to in matching circumstances.


Options

To this day, you can add predication over the following:

  • Block breaking
  • Block interacting
  • Entity attacking
  • Entity interacting
  • Item attacking
  • Item using
  • Item crafting

    • via grid crafting (in inventory, in crafting table)
    • cooking (all sorts included)
    • stone-cutting (due to vanilla limitations, will cause mismatches between client rendering and actual recipe output)
    • smithing
  • Chat
  • Command execution

Please read the wiki for more informations on how to use the mod.


Predicates expansions

In order to provide a better control over its functionalities, Predicator expands on the vanilla predication tools, such as adding text-based predicate conditions, computing number providers, and more! Read more about it all on the wiki.
