[0.17.11] Can't set currently burning to an item without a fuel value

[magu5026]

I dont know if that's really a bug or something else.

I'm trying to put a fuel item in a burner of a locomotive with my mod.
I've stored this element in a global variable at the beginning (init + configuration_changed) of this mod:

Code: Select all

global.Fuel = game.item_prototypes ['nuclear-fuel']

In several functions I insert this object into the burner (train is the entity of the locomotive):

Code: Select all

 
train.burner.currently_burning = global.Fuel
train.burner.remaining_burning_fuel = global.Fuel.fuel_value

In 0.16.51 it works fine, but after 0.17 some users have received this error:

Can't set currently burning to an item without a fuel value.

PLS help me.

greetings magu5026

I was going to say you need to put the global definition in on_init and maybe also on_configuration_changed, but then as I quoted, I re-read when you put, and... oh, you said you did do that.

My next thought is... does nuclear-fuel have a fuel value? in the base game, yes, but is it possible that the people reporting this issue are using a mod where it doesn't?

Unless there is a specific reason why you're using nuclear-fuel, instead of just using existing objects, try defining your own dummy fuel in the data phase, and use that in your script instead of nuclear fuel.

I've already tried that. First, I created my own fuel item.

Code: Select all

local fuel = table.deepcopy(data.raw['item']['wood'])
fuel.name = "own-test-fuel"
fuel.flags = {"hidden"}
fuel.fuel_value = "10GJ"

But after updating to 0.17, it crashed. So I tried to use an item that was already in game.

for something as simple as a fuel item, I wouldn't use the table.deepcopy method, I would just copy the entire code directly into your mod and edit as a appropriate. I usually reserve table.deepcopy (Actually, I don't use it at all, instead I prefer to use util.merge) for copying entities, because those are more likely to break with updates and can have quite a long complex amount of code in them, especially when it comes to graphics.

[magu5026]

I'll try it. Some users modified my mod and tried the following:

deepcopy changed from "wood" to "nuclear-fuel"
replaced every instance of "global.Fuel" with "game.item_prototypes['own-test-fuel']

Some still have the problem and some have solved the problem.

You can choose the item / recipe and get which mod has it changed.

You can see which mod is it: yellow text said that it was "Ice Ore" mod.

I don't understand what that should do and how it can help with my problem.
Thanks anyway for your help.
