Existing items filter for importers (Refined Storage)
Java mod listed for Minecraft 1.18. Downloads from the MC Java Mods app on Android.
Adds a craftable filter for importers that changes the importer behaviour to only take items out of the container that are already present in the storage…
⬇ Download on ModrinthRS Existing Items Filter adds a new optional filter item for Refined Storage Importers. It is designed for situations where you want an Importer to accept only item types that are already stored somewhere in its connected Refined Storage network.
Place an Existing Items Filter into any of the nine filter slots of a standard Refined Storage Importer. Once present, the Importer checks each item in the attached container against the contents of the network. If the network already contains that item type, it can be imported. If the item does not yet exist in the network, the Importer leaves it in the container.
Removing the Existing Items Filter restores the Importer’s original behavior. Importers that never use the filter work exactly as Refined Storage intended.
The filter can also be combined with ordinary Importer filters. Existing whitelist or blacklist entries and Refined Storage’s comparison settings continue to apply, while the Existing Items Filter adds the extra requirement that an accepted item must already be present in the network. When used by itself, it accepts every item type currently stored in the network.
The crafting recipe is shapeless and requires:
One Refined Storage Filter
One Refined Storage Detector
One Eye of Ender This mod currently affects standard Refined Storage Importers with nine filter slots. It does not alter fluid importing or importers added by other mods, such as Extra Storage’s Advanced Importer.
