Icterine Mod (1.21.11, 1.20.1) – Advancements Optimization

Frequent advancement checks can become noisy in heavily used inventories, especially around item pickups and container interactions. Icterine Mod focuses on optimizing how Minecraft handles advancement triggers tied to InventoryChangeTrigger, while keeping the scope practical: all changes are server-side, vanilla advancements are not affected, and every vanilla injection can be disabled in the config file.

Key Features

  • Optimizes advancement triggering for obtaining items, with a specific focus on InventoryChangeTrigger.
  • Works on the server side only, making the changes relevant where advancement checks are processed.
  • Can skip criteria when slot count requirements do not match, or when a criterion has no item requirements.
  • If a criterion has only one item requirement, the changed stack is checked directly against that requirement.
  • Includes configurable vanilla code injections, and each of those injections can be disabled in the config file.
  • May break parity with vanilla in some cases, but vanilla advancements are not affected; if something does behave differently, the advancement should still be obtainable by dropping and picking up one required item.
