So... I'm now working on a pretty big mod, which adds 9 new machines to craft items in. The only way i can create graphics is by downloading images and editing them, because that's the only thing i know how to do. It is enough for making item icons, but making animated machines is for me an ...

Thanks for quick response!
I dug trough your code for hours and also found the varible c not assigned, but still used. I thought it's some modding/lua trick I don't know yet, because otherwise it would be null.
Do I need to make variables inside functions and loops local too?

this is the mod: https://mods.factorio.com/mod/CustomModules
and i think all versions will cause this issue, but all except the last one have proven to be somewhat buggy or incompatible, so work with the last one (0.16.1)

when fixed, it can finally do wat is it supposed to and I can read the log:
1.415 Script @__DeadlockStacking__/prototypes/shared.lua:229: ERROR: DSB asked to use icon_size that is not 32, 64 or 128 (raw-wood)
1.415 Script @__DeadlockStacking__/prototypes/shared.lua:229: ERROR: DSB asked to use ...

There is an error in that line. There should be item_name, not item-name.

so a better option is
if icon_size and (icon_size ~= 32 and icon_size ~= 64 and icon_size ~= 128) then
log("ERROR: DSB asked to use icon_size that is not 32, 64 or 128 ("..item_name..")")
--return
icon_size = 32
end

No items from my mod can be stacked and all icons are 32x32. By disabling parts of my mod I have found out, that everything works until I add a recipe. Then it breaks.
It really makes no sense.

BUG : Breaks without any reason when used with my mod called CustomModules. Replacing part of code in create_stacking_recipes and create_unstacking_recipes with this fixes the issue:

if icon_size and (icon_size ~= 32 and icon_size ~= 64 and icon_size ~= 128) then
--log("ERROR: DSB asked to use ...

I made a mod which adds custom modules . The icons consist of multiple layers and two of them have some shift{} applied. In inventory the item appears right, but the Alt-view of modules is messed up - the shift is not scaled properly. (the lights are escaping the ...

After lots of trial and erro i created this:
for i, r in pairs(data.raw.recipe) do
if r.ingredients then
for j, n in pairs(r.ingredients) do
if n.name and string.find(n.name, "speed-module") then
n.name = "module-B0"
end
if n[1] and string.find(n[1], "speed-module") then
n[1] = "module-B0 ...

I'm making my own modules to replace the vanilla ones, but because of compatibility i just removed the crafting recipes for the normal modules. Now i want to replace all "speed-module" in ingredients of all recipes with "module-B0" but I can't seem to find a way to do it.

I could also make the modules change their stats when inserted into the machine (they will be usable only in one machine). After every research finishes the code will check if it was the research I wanted. If yes, update all modules in the machine.

Is it possible to somehow change module values or change it's prototype in control.lua?

So it looks like I can't access speed or productivity. Is it at least possible to modify a global variable with a research? I could then do some stuff in control.lua

@ Optera
Thanks, i was searching for a mod with an infinite research to learn from.

I'd like to create my own infinite research to increase speed and/or productivity of a certain machine. The problem is I only know how to add regular researches and I don't know how to make the research apply bonuses to my machine.

Thanks. Sorry for being so incompetent to look it up myself.

Thanks! But what happens when all the items have the same order?

I see the value order needed in almost any prototype, so inspired by other mods i just set it to "a-b", but I have no idea what does it do. Could somebody please explain? thanks.

Make big sprites with alpha gap and shift this picture higher/ lower.

I tried making the picture double the height with the upper half transparent and then shifting it back by 2 tiles.
(it is a part of animation)

width = 128,
height = 256,
frame_count = 1,
line_length = 1,
shift = {0.0, -2.0 ...

Yep, i didn't think of that, thanks for pointing it out!
