Hello,

I'd appreciate it if anyone can offer some guidance. I've searched the internet, but couldn't find anything to help me.

What I'm trying to do is supposedly simple. I'm not a modder nor a programmer. I have the SA mod for Factorio, and I would like to tweak it so that the electricity research is a little further down, maybe needs additional science packs. I've opened the technology file in the mod folder and edited a few parts, but apparently what I'm trying to do is harder that I thought.

Is there a guide on how to precisely edit the tech tree; change how tech parts are related to each other?

Thanks

Here is some code that shows how to remove items from tech research. You can add some into the structure as well.

Code: Select all

-- RemoveBlackScience
data.raw.technology['exoskeleton-equipment'].unit.ingredients = 
{
  {"automation-science-pack", 1},
  {"logistic-science-pack", 1}
  -- {"military-science-pack", 1}
}

   data.raw.technology["engine"].prerequisites =
   {
      "automation-science-pack"
   }
   data.raw.technology["engine"].unit.ingredients =
   {
      {"automation-science-pack", 1},
   }

-- and one of my favourites: 
-- force belt immunity on
data.raw['character']['character'].has_belt_immunity = true

data.raw.technology["belt-immunity-equipment"].hidden = true
data.raw.technology["belt-immunity-equipment"].visible_when_disabled = false

data.raw.recipe["belt-immunity-equipment"].hidden = true
data.raw.recipe["belt-immunity-equipment"].hidden_from_player_crafting = true

table.insert(data.raw.item["belt-immunity-equipment"], flags)
data.raw.item["belt-immunity-equipment"].hidden = true
