"Total raw" calculation

DaveMcW · Post by **DaveMcW** » Tue Jun 17, 2014 8:23 pm

The raw resources calculation is inconsistent between buildings. I think it should always show the base resources (iron ore, copper ore, coal, oil, water, wood, alien artifact) wherever it is viewed.

This is not a bug. This is an intended behavior. It always shows the "lowest recipes" in the tree that this machine can craft. So the assembling machine doesn't know how to craft the battery, therefore the battery is "raw" resource for the assembling machine.

I am moving this to ideas & suggestions. If this is annoying to many people we can think about changing this. Though there are some tricky subtle technical issues with this

I think we need both info: the gross and the net calculations (in German and many other languages "brutto" and "netto"). I suggest a tab with the current as default.

The current is almost useless. Maybe it is nice to see for manual crafting. But when I pick a recipe in an assembler I can only use the main ingredients. I don't care where the ingredients are made, it is just as easy to build another assembler or chemical plant.

I can see how there would be a problem picking between multiple recipes. There are 3 gas recipes (basic-oil-processing, advanced-oil-processing, light-oil-cracking). And an infinite loop with crude oil barrels. So you would need a variable to identify which should or should not be used.

I would say use basic-oil-processing for all 3 refinery products. It will give you the maximum crude oil needed, and players can decide whether to use advanced oil processing to reduce that number. Just like they can use productivity modules to reduce all numbers.

I wrote a lua script to do it.

Lua Script

Code: Select all

package.path = package.path .. ';data/core/lualib/?.lua;data/base/?.lua'
require "dataloader"
require "data.base.data" 

data.raw.recipe["empty-crude-oil-barrel"].hidden_from_recipe_tree = true;
data.raw.recipe["advanced-oil-processing"].hidden_from_recipe_tree = true;
data.raw.recipe["heavy-oil-cracking"].hidden_from_recipe_tree = true;
data.raw.recipe["light-oil-cracking"].hidden_from_recipe_tree = true;

function getRecipe(item)
	local count = 1
	for i,recipe in pairs(data.raw.recipe) do
		if (recipe.results) then
			for j,product in pairs(recipe.results) do
				if (product.name == item) then 
					if (not recipe.hidden_from_recipe_tree) then
						return recipe
					end
				end
			end
		end

		if (recipe.result == item) then
			if (not recipe.hidden_from_recipe_tree) then
				return recipe
			end
		end
	end
	
	return nil
end

function getIngredients(recipe)
	local ingredients = {}
	for i,ingredient in pairs(recipe.ingredients) do
		local name, amount = 0
		if (ingredient.type) then
			name = ingredient.name
			amount = ingredient.amount
		elseif (ingredient[1] and ingredient[2]) then
			name = ingredient[1]
			amount = ingredient[2]
		end
		if (amount > 0) then
			local subrecipe = getRecipe(name)
			local multiple = 1;
				if (subrecipe and subrecipe.results) then
					for j,product in pairs(subrecipe.results) do
						if (product.name == name) then 
							multiple = product.amount
						end
					end
				elseif (subrecipe and subrecipe.result == name and subrecipe.result_count) then
					multiple = subrecipe.result_count
				end

			if (subrecipe == nil) then 
				ingredients[name] = amount / multiple
			else
				for subname,subamount in pairs(getIngredients(subrecipe)) do
					if (ingredients[subname]) then
						ingredients[subname] = ingredients[subname] + subamount * amount / multiple
					else 
						ingredients[subname] = subamount * amount / multiple
					end
				end
			end
		end				
	end

	return ingredients	
end

function round(num, idp)
  return tonumber(string.format("%." .. (idp or 0) .. "f", num))
end
	
for k,recipe in pairs(data.raw.recipe) do
	print(k)
	local ingredients = getIngredients(recipe)
	for name,amount in pairs(ingredients) do
		print(round(amount, 1) .. "x " .. name)
	end
	print ""
end

I like those very praxis-orientated stuff.

DaveMcW - I believe your crude oil numbers are a bit high. I also think that crude becomes problematic because you have two ways to produce it. For instance, if I need 2 units of lubrication for an electric engine unit, that can be considered 2 units of crude under basic refinery (10 crude in and 3 heavy, 3 light and 4 petro out) or 1.8 units of crude under advanced refinery (10 units of crude produce 11 items of Heavy, Light and Petro - 1, 4.5, 5.5).

I discovered the discrepancy because I can't find the published formula for the Electric Engine Unit. I'm getting 2 Lub, 1 engine unit and 2 ckts?

DaveMcW · Post by **DaveMcW** » Sat Jun 28, 2014 6:01 pm

I think you're right. It's better to assume all refinery products are equally valuable, instead of only looking at a single product. If people use cracking the crude oil costs might be off by 20%, but that's closer than being off by 200% like I was.

I played around with the script some more, and managed to eliminate the hidden_from_recipe_tree variable. It now avoids infinite loops on its own, and picks the cheapest recipe. This should allow it to handle any new recipe with no effort on the part of the modder.

In practical terms, this means:
empty-crude-oil-barrel: ignored because of infinite loop
heavy-oil-cracking: ignored because basic-oil-processing is cheaper
light-oil-cracking: ignored because basic-oil-processing is cheaper
advanced-oil-processing: ignored because (10 crude)/10 is cheaper than (10 crude + 5 water)/11

You could argue that 1 oil is more valuable than 5 water, but we would need a custom database entry to teach the game that.

Brilliant script, thank you!
works ingame too, and i added a "time" entry in the return table, which should be 100% correct

Hey!
Can you give me hint how to run this script in v0.17? And how to extract the raw data? Thank you :)

I think you can use this:
https://mods.factorio.com/mod/MaxRateCalculator

It says it has 0.17 support..

Yep, but that is not the information I was looking for. I basically need the output of that LUA script from 0.17, to do some data mining. So I was looking for a way the script would work for me. But so far Someone's LUA-Console mod didn't help in running the script, as I do not have the experience needed for it. That is why I'm asking about it here

[EDIT]
Now I guess I'm looking for the same things but in 0.18 ^_^
