Help combining solar panel and accumulator.

[Jcewazhere]

Pre-edit: while typing this post up I found one obvious problem, my control.lua is blank and I have no idea what to put in there. The tutorial on the wiki has some code for making a bomber, and the control.lua's I've looked at in the main game folders don't seem to have code specific to the solar panels.

I'm trying to make a quick and dirty mod that combines a solar panel and an accumulator, making a solar-battery and saving tons of space. I mean it's not like we are in some 2D universe where you can't have stuff on top of other stuff
I've followed the wiki tutorial as close as possible while not making a bomber, but now that I think my mod is complete and want to test it in-game I get an error saying "Error in assignID, 'solar-battery' was not recognized id of entity". I've searched for that error on the forums and found a few things to try but none worked, maybe those fixes were for older game versions or I have an error between the keyboard and my chair.

In my C:\Users\jcewazhere\AppData\Roaming\Factorio\mods folder I have the "solar-battery" folder and mod-list.json. (windows 7 64 bit version)

In the solar-battery folder I have a folder for graphics, I just made a quick solar-battery.png in paint.net, and I have the stock accumlator graphics in a folder as well. Then I have a prototypes folder, and a sound folder. The sounds are direct cut/paste from the basic accumulator.

Then I have control.lua, but I'm not sure what to put there. I've been mostly taking code from the stock items and putting it where I think it needs to go, but the tutorial is for a bomber and the control.lua's from the main game are not very forthcoming with ideas.

Then I have data.lua:
require("prototypes.item")
require("prototypes.recipe")
require("prototypes.entity")
like the tutorial says.

Then I have info.json:

{
"name": "solar-battery",
"version": "0.1.1",
"title": "My first mod",
"author": "Jcewazhere",
"description": "Solar panel and accumulator in the same block space"
}

Inside the prototypes folder I have the following files:

entity.lua

data:extend({
type = "item",
name = "solar-battery",
icon = "__solar-battery__/graphics/icons/solar-battery.png",
flags = {"placeable-neutral", "player-creation"},
minable = {hardness = 0.2, mining_time = 0.5, result = "solar-battery"},
max_health = 100,
corpse = "big-remnants",
collision_box = {{-0.9, -0.9}, {0.9, 0.9}},
selection_box = {{-1, -1}, {1, 1}},
energy_source =
{
type = "electric",
buffer_capacity = "5MJ",
usage_priority = "terciary",
input_flow_limit = "300kW",
output_flow_limit = "300kW"
},
picture =
{
filename = "__solar-battery__/graphics/entity/solar-panel/solar-battery.png",
priority = "extra-high",
width = 124,
height = 103,
shift = {0.7, -0.2}
},

charge_animation =
{
filename = "__solar-battery__/graphics/entity/basic-accumulator/basic-accumulator-charge-animation.png",
width = 138,
height = 135,
line_length = 8,
frame_count = 24,
shift = {0.482, -0.638},
animation_speed = 0.5
},
charge_cooldown = 30,
charge_light = {intensity = 0.3, size = 7},
discharge_animation =
{
filename = "__solar-battery__/graphics/entity/basic-accumulator/basic-accumulator-discharge-animation.png",
width = 147,
height = 128,
line_length = 8,
frame_count = 24,
shift = {0.395, -0.525},
animation_speed = 0.5
},
discharge_cooldown = 60,
discharge_light = {intensity = 0.7, size = 7},
working_sound =
{
sound =
{
filename = "__solar-battery__/sound/accumulator-working.ogg",
volume = 1
},
idle_sound = {
filename = "__solar-battery__/sound/accumulator-idle.ogg",
volume = 0.4
},
max_sounds_per_type = 5
},
production = "60kW"
})

item.lua

data:extend({

{
type = "item",
name = "solar-battery",
icon = "__solar-battery__/graphics/icons/solar-battery.png",
flags = {"goes-to-quickbar"},
subgroup = "energy",
order = "b[solar-battery]-a[solar-battery]",
place_result = "solar-battery",
stack_size = 50
}

})

and finally recipe.lua

extend({
{
type = "recipe",
name = "solar-battery",
enabled = "true",
ingredients =
{
{"steel-plate", 5},
{"electronic-circuit", 15},
{"copper-plate", 5},
{"iron-plate", 2},
{"battery", 5}
},
result = "solar-battery"
}
})

I planned on tweaking things like the crafting recipe, power generation rate and storage once I had it working. Right now I'm just trying to get it to work. Any help would be appreciated, thanks in advance.

I hope spoilers just don't work in the preview, if not I'm sorry for the long post, at least I tried to use them

PS: Whoever decided the text box and the cursor should be the pretty much the same color is a very annoying person

Try rearranging data.lua

require("prototypes.entity")
require("prototypes.item")
require("prototypes.recipe")

Thanks for the response, but it didn't work.

you have 2 [type="item"] (first add and second modify that item, but you need a entity)
try change type of "entity.lua" to [type = "solar-panel"], maybe it work

[Jcewazhere]

I changed entity.lua like you suggested, still have the same error.
Thanks anyway.

I'm probably over-complicating this, since it's my first real mod I should keep it simple. All I really want to do is add energy storage to a solar panel. I don't need graphics or sounds or custom textures.

The error should also give a line number, or say (near wordincodehere), try either typing out what it says in the error completely, or just take a screenshot of it. From what I see, it's very likely either your folder name does not match the info file, or the order = "b[solar-battery]-a[solar-battery]" doesn't work for custom items unless defined for them. Keep the type="solar-panel" though, pretty sure that might fix some problems.

[Jcewazhere]

Here's a screenshot of the error, thanks for the reply.

Maybe I derped on the folder structure so here's that:

Entity definition should be in array like in item definition. + your entity type is item.
