Factorio Forums

I'm wondering if this is possible. I'd like to create an item you use for selecting entities. This item would save a list of entities for later use. Then, when using the item, it would refer to the saved list within the item itself rather than a global variable. Is there a way to assign metadata to an item after it's use (similar to how blueprints work)?

There's currently no way to do that in mods.

The only workaround I am aware of at this time is the Factorisimo mod. It uses the item's durability as a array index.

Obviously any mod that screws with item health will break it.

Also there was talk of merging damaged items in inventory (to reduce number of slots taken) which would break the factorissimo approach.

Only other thing I can think of is to experiment with "item with label" and see if that might work?

Yea. I think we need this functionality before they implement item merging. Although I still think letting you use repair kits on items in your inventory is a better approach.
