Is there a way to add attributes to items?

I'm working on making rocket fuel as a burnable fuel, worth 10x solid fuel, but I can't seem to be able to mod it in.

Code: Select all

--in rocket-fuel.lua
data:extend(
{
	{
	type = "item",
	name = "rocket-fuel",
	fuel_value = "250MJ"
	}
}
)

This is the code for solid-fuel

Code: Select all

{
    type = "item",
    name = "solid-fuel",
    icon = "__base__/graphics/icons/solid-fuel.png",
    flags = {"goes-to-main-inventory"},
    fuel_value = "25MJ",
    subgroup = "raw-resource",
    order = "c[solid-fuel]",
    stack_size = 50
  }

By using this as a template we can easily make rocket fuel by changing a few things.

Code: Select all

{
    type = "item",
    name = "rocket-fuel",
    icon = "__YouMod__/path/to/icon.png", --change this to a path to your icon for the item.
    flags = {"goes-to-main-inventory"},
    fuel_value = "250MJ",
    subgroup = "intermediate-product",
    order = "c[solid-fuel]",
    stack_size = 50
  }

And that's it. you can find the code for all items, entities and much more in /factorio/data/base/prototypes

Or you can do this:

Code: Select all

data.raw.item["rocket-fuel"].fuel_value = "250MJ"

More elegant and doesn't overwrite any other properties of rocket fuel, ie it's more compatible with other mods.

I just tried this, and it doesn't seem to work.

Code: Select all

table.insert(data.raw.item["rocket-fuel"],{fuel_value = "250MJ",})

It does not seem to work but it probably would look something like that.

Then you've done something wrong because it worked perfectly fine for me.

You know what, here you go, I've made the mod for you:
