FTB Filter System

Overview

FTB Filter System (aka FFS) is a powerful item filtering mod with friendly GUI editing. It doesn't do much on its own, but is intended to be used by other mods which need to filter items; FTB Quests in particular, but it offers an API which any mod can use.

Using FFS

FFS adds a single item, the Smart Filter. All configuration is done via this item, by simply right-clicking it. This opens a GUI, with a list which initially contains just a "Root" element, and "Add" / "Delete" / "Configure" buttons on the right:

Click "Add…" to pop up a list of available subfilters which you can add.
- On the left side of the list are compound filters, to which more filters can be added as children, forming a filter hierarchy.
- On the right side (in possibly multiple columns) are basic filters, which do actual matching against items.
- All the filter buttons have a tooltip with a brief explanation of what they do (should be obvious in general)
Click "Delete" to delete the currently-selected filter.
- Deleting a compound filter also deletes all its children
Click "Configure…" to pop up another screen allowing the currently-selected filter to be configured
- Not all filters can be configured; compound filters don't have any configuration, and some basic filters don't either
- You can also double-click any filter in the list to open its configuration screen

At the bottom are "Done" and "Cancel" buttons:

Click "Done" to save any changes you've made to the filter
Click "Cancel" (or press Escape) to discard any changes (you will be prompted to confirm discarding unsaved changes)

Other tips and tricks:

Some filters allow dragging of items from JEI to configure them: the Item Filter, the NBT and Fuzzy NBT filters, and the Mod filter
Filters can be dragged in the list to move them around in the filter hierarchy, subject to the following rules:
- The Root filter can never be moved
- Filters can only be dragged onto compound filters
- Compound filters can only be dragged onto filters at the same level or higher up in the hierarchy (dragging a filter into its own child isn't a very sane thing to do…)
You can quickly test if a filter matches what it's supposed to:
- Hold the configured filter in your main hand, and the item to be tested in your offhand
- Then sneak-right-click the filter and you'll get a chat response indicating a match success or failure
