remote interface call questions

[Galacticruler]

I was wondering if it was possible to do a few things using the

Code: Select all

remote.add_interface(interface_name, table_of_functions)

code. Namely make it see if two mods are installed and only fire-up if both are there, and secondly adding an entire turret only in the event that one of them is installed.

If both mods have a remote interface it will work:

Code: Select all

if remote.interfaces.modA and remote.interfaces.modB then

but since you're talking about adding a turret i think you want this to happen in data.lua? data.lua doesn't have remote available, so you'll have to check data.raw for items/turrets added by these 2 mods. And add them as optional depenencies, so they are loaded before your mod (or do it in data-updates.lua)

Code: Select all

if data.raw["item"]["item-from-modA"] and data.raw["item"]["item-from-modB"] then

after the then on the data.raw what would I do to create the entity, item, and recipe for the new turret? as well as add it to a technology?

The usual data:extend() thing.

Code: Select all

if data.raw["item"]["item-from-modA"] and data.raw["item"]["item-from-modB"] then

okay, so I'm probably doing this wrong, but it keeps saying the item I'm trying to index is a nil value.
currently it looks like this:

Code: Select all

if data.raw["charge-pack"]["advanced-weaponry"] then

[prg]

"charge-pack" is not a valid type defined by the game. You can't just put something you made up yourself there. What is the prototype you're trying to access?

Oh, that makes a bit more sense, its not an item name it the item type?

[prg]

It's data.raw["type"]["name"], so e.g. data.raw["item"]["small-electric-pole"] for the item in your inventory or data.raw["electric-pole"]["small-electric-pole"] for the placed entity. Just use the type and name of the prototype.
