Detect placement of blueprint

[PFQNiet]

What is the proper way to respond to a blueprint being placed? I would like to have a table of ghosts to do stuff with.

Would this be done as just a large number of entity creation events where the entity is a ghost? If so, how would I tell the difference between an item holding a single entity, or shift-clicking to place a ghost?

What about copy-paste? Is this just a temporary blueprint that can be handled in the same way?

Yes. If you need all ghosts in one table, you can collect them in on_built_entity, store them in a table, and process/delete the table in on_tick.

Check player.cursor_stack to see what they used.

You should keep seperate tables for each player in case several players build simultaneously.
