Research for recipes?

[henryheyhey123]

Is it possible to add research prerequisites for recipes? If so, where do I put it in my code?

Thanks in advance! 

[Rikiki]

Hey, got the same question!

But no way for now, you have to put limitations via .DLL.

[Shinzy]

You could still have the recipes require certain level of crafting skill, to have that similar progression curve thingie or whatever

[Rikiki]

Yep but the problem is that you don't want a workbench being able to craft Item Mark III when you just researched Item Mark I.

Did not yet tested it but I would try this piece of code for a custom workbench class:

class MyCustomWorkbench : Building_WorkTable
{
   private bool itemMarkIIIRecipeIsAdded = false;

   public override void TickRare()
   {
      base.TickRare();

      if ((itemMarkIIIRecipeIsAdded == false) && (Find.ResearchManager.IsFinished(ResearchProjectDef.Named("ItemMarkIIIResearchName")) == true))
      {
         Thing abstractWorkbenchContainingAllMyRecipes = ThingMaker.MakeThing(ThingDef.Named("AbstractWorkbenchContainingAllMyRecipes"));
         RecipeDef recipeToAddDef = abstractWorkbenchContainingAllMyRecipes.def.recipes.Find(myRecipe => myRecipe.defName == "ItemMarkIIIRecipe");

         def.recipes.Add(recipeToAddDef);
         itemMarkIIIRecipeIsAdded = true;
      }
   }
}


You must define 2 workbenches in XML. One that contains all your custom recipes but is not buildable (remove the <DesignationCategory> line) and the other is your custom workbench which has only Item Mark I recipe and contains a <researchPrerequisite>ItemMarkIResearchName</researchPrerequisite>.

Thank you for the help, but I've been getting does not exist in current context errors from this code:

I tested it and it works.
I will give you the complete code example tomorrow, I need to sleep now...

I think there might be a bug in your XML if you cannot wait for the answer

                    Spoonge = true;

                }

            }
        }
    }
}

This is the working code, its mostly copy/place from rikikis source code, Spawnsetup is require so that recipes wont multiply in 
choose recipe option.

But rikiki i got a question, what  this line do ?

Code Select Expand

typeof(ThingDef).GetField("allRecipesCached", BindingFlags.Instance | BindingFlags.NonPublic).SetValue(ThinkerTable, null);
All i figure out is that it require this wierd thing "System.Reflection"

[Rikiki]

From what I understood, System.Reflection is similar to the getContainerOf Linux macro.

So it basically gets the allRecipesCached member from your Building_Worktable object and set it to null.
=> typeof(ThingDef).GetField("allRecipesCached", BindingFlags.Instance | BindingFlags.NonPublic).SetValue(ThinkerTable, null);

If you look into the core code, setting allRecipesCached to null will force the worktable to refresh its recipes list. And the job is done!

The original code is from RawCode. I don't really know how System.Reflection works .

[mrofa]

Nahh its cool i doung i would understand what it do anyhow
Thanks alot

[StorymasterQ]

System.Reflection is used for a check that, if it's null, then it your computer is a vampire.

...joking, but it's a good troll answer.
