I'd like to know what item was used when placing an entity, I think it'd be most useful for the on_put_item event, but a second would be the on_built_entity event, although that does not really have to be with an item.

The item is the item in the players cursor.

Oww, so it goes about like this: On put item> on entity build> item taken from cursor?

yes.

Ah, damn. I forgot the cursor stack holds the item for building the entity. (I knew it when making Creative Mode, but then forgot it when making new mods.)

Would you mind adding description about this on the doc please?


Edit: oh wait! I think the order above is incorrect.
It should be: on_put_item -> item taken from cursor -> on_built_entity

If the player has spent the last item, cursor stack will be invalid for read in on_built_entity. In that case, it is not possible to know which item was used to build the entity.

Maybe it is related as well: placed_item in on_built_entity/on_robot_built_entity

Well, you do have access to who built the entity, as well as the entity type. Unless you have more than one item definition to place the same entity, it shouldn't be an issue. But in that case, why would you have multiple items to place the same entity type?

I'm not really concerned why someone would make it so, i want my nod to work when someone does do it.
