FilterFactory

A filter factory, which creates filters when resources are (re)loaded (when the game starts, or the player presses F3+T).

Each filter factory will be run for each resource when loading resources.

Each filter accepts an interaction, processes it, and returns a result whether a texture should be replaced or not, and if yes, provides a replacement texture.

To process anything other than block entities and entities, (for example, creative inventory, anvil screen, most villager job sites), these preprocessors are not available. Processing either takes place in UseBlockCallback.interact, or in the filter created by createFilter. In the first case, check if the world is client-side, and if the targeted block is added by your mod (check ID with RegistryLookupService.lookupBlockId), call InteractionService.interact. In the latter case, you can use Interaction.rawInteraction. These details come from UseBlockCallback.interact, but this runs every game tick, instead of only once, when the interaction happens. You can pass a copy of the interaction with modified details using Interaction.copy.

You can add a filter for Interaction.texture as the first filter to avoid unnecessary computing.
