Adding a recipes to the character filter?

[amazingGob]

i want to add recipes to my modded character tab

AddRecipeToFilter("spear", "CHARACTER")

i tried this but it made it so that everyone also have it in their tab, what am i missing?

This function only ensures that your prefab is in that group, but it does not ensure that only your character can access that group.

i see... how do you suggest i go about this then?

AddCharacterRecipe(...) with builder_tag = "character_tag"

ohhh so if im reading this right, i have to basically make a new identical recipe for them?

That's the function:

env.AddCharacterRecipe = function(name, ingredients, tech, config, extra_filters)
  initprint("AddCharacterRecipe", name)
  require("recipe")
  mod_protect_Recipe = false

  local rec = Recipe2(name, ingredients, tech, config)

  if config ~= nil and (config.builder_tag ~= nil or config.builder_skill ~= nil) then
    env.AddRecipeToFilter(name, CRAFTING_FILTERS.CHARACTER.name)
  else
    initprint("Warning: AddCharacterRecipe called for recipe "..name.." without a builder_tag or builder_skill. This recipe will be added to the mods filter instead of the character filter.")
    env.AddRecipeToFilter(name, CRAFTING_FILTERS.MODS.name)
  end

  if extra_filters ~= nil then
    for _, filter_name in ipairs(extra_filters) do
      env.AddRecipeToFilter(name, filter_name)
    end
  end


  mod_protect_Recipe = true
  rec:SetModRPCID()
  return rec
end

It is important to mention that "builder_tag" has to be inside the "config" table, like

local config = {builder_tag = "your_tag"}

And I think your character needs to have "your_tag" in order to build the thing.

You need to replace AddPrefab2 or the function you are using to register your prefab with AddCharacterRecipe, you can just replace the name and add the configuration table, both receive the same first three parameters.

how would you go about adding everything from a tab like the celestial alter tab into a character tab? most guide i can find uses the old system and doesnt seem to work anymore :c

I just found this method, in recipes.lua you can see what common feature the objects you want to add have

for i,v in pairs(AllRecipes) do
  if v.station_tag ~= nil and v.station_tag == "celestial_station" then
    -- ...
  end
end

What's the old method you found? Maybe that will help me find a better solution.

The thing is, AddRecipe in the builder component doesn't add the recipe to something, it makes you learn it. Now, I think what you want is for items from other tabs to appear in your character's crafting tab, ready to be crafted. I think you can achieve this by combining the function I gave you (if you don't want to go through the items one by one) and applying the AddRecipeToFilter function you mentioned at the beginning. Finally, this will probably work, but they will appear locked. To unlock them, use AddRecipe in your character's builder. This way, they will have already learned them and, in theory, they will be able to craft them without having the corresponding research lab.

If it doesn't seem to work, apply the exact same thing to builder_replica. I don't understand the difference between the original component and its replica, or why a replica even exists, so I can't tell you which one to use to make it work.

hmm i tried doing this 

 -- Add recipes
	for i,v in pairs(AllRecipes) do
		if v.station_tag ~= nil and v.station_tag == "celestial_station" then
			AddCharacterRecipe(v,v.recipes, GLOBAL.TECH.NONE, {builder_tag = "testchar",} , {"CHARACTER"})
		end
	end

but im getting this error 

[00:00:01]: [string "../mods/char/modmain.lua"]:83: bad argument #1 to 'pairs' (table expected, got nil)

if you are in modmain.lua, use GLOBAL.AllRecipes

[amazingGob]

--modmain.lua

	for i,v in pairs(GLOBAL.AllRecipes) do
		if v.station_tag ~= nil then 
			if v.station_tag == "celestial_station" or v.station_tag == "lunar_forge" then
				AddCharacterRecipe(v.name,v.ingredients, GLOBAL.TECH.NONE, {builder_tag = "testchar",} , {"CHARACTER"})
      		end
		end
		
	end

ok i figured it out!!! somehow, its mostly just a lot of trial and error i dont really know how i ended up getting it to work

oh!!! i was switching between modmain and the prefab file tbh, i couldnt do it in the prefab file because i dont know how to call AddCharacterRecipe in there

also i have to use v.name instead of just v in AddCharacterRecipe or ill get this error

[00:00:00]: [string "scripts/recipe.lua"]:105: attempt to concatenate field 'product' (a table value)
LUA ERROR stack traceback:
        scripts/recipe.lua(105,1) in function '_ctor'

        scripts/class.lua(191,1) in function 'Recipe2'
        scripts/modutil.lua(763,1) in function 'AddCharacterRecipe'

either way it's solved now thank you a lot for the help!
