Factorio Forums

I can unlock a technology by requiring the user to build a specific entity, but I can not do so on a specific entity type. This may lead to soft-locks if e.g. a trigger depends on "roboport" but some mod removed roboport and replaced them with "foo-roboport". It would be nice if BuildEntityFilter could also accept an entity type (and then show all entities that match in the technology tree prerequisites).

I think this was put into the wrong forum section? You are correct: the prototype property defined as a specific entity only binds to a specific entity.
