How would I add a recipe, that has the same recipe as diamond armor, but gives you wheat? It would be helpful if the method didn't edit any base files too :I

cant you just remove the original and then insert the new one

#reflection

Example with wooden door

 

Imports needed:

import java.util.ArrayList;

import net.minecraft.item.crafting.CraftingManager;
import net.minecraft.item.crafting.IRecipe;
import net.minecraft.item.crafting.ShapedRecipes;
import net.minecraft.item.crafting.ShapelessRecipes;
import net.minecraftforge.oredict.ShapedOreRecipe;
import net.minecraftforge.oredict.ShapelessOreRecipe;

 

Remove Recipe Method:

public static void removeRecipe(ItemStack resultItem)
{
         ItemStack recipeResult = null;
         ArrayList recipes = (ArrayList) CraftingManager.getInstance().getRecipeList();
         for (int scan = 0; scan < recipes.size(); scan++)
         {
                 IRecipe tmpRecipe = (IRecipe) recipes.get(scan);
                 if (tmpRecipe instanceof ShapelessRecipes)
                 {
                         ShapelessRecipes recipe = (ShapelessRecipes)tmpRecipe;
                         recipeResult = recipe.getRecipeOutput();
                 }
                 else if (tmpRecipe instanceof ShapedRecipes)
                 {
                         ShapedRecipes recipe = (ShapedRecipes)tmpRecipe;
                         recipeResult = recipe.getRecipeOutput();
                 }
                 else if (tmpRecipe instanceof ShapedOreRecipe)
                 {
                 ShapedOreRecipe recipe = (ShapedOreRecipe)tmpRecipe;
                         recipeResult = recipe.getRecipeOutput();
                 }
                 else if (tmpRecipe instanceof ShapelessOreRecipe)
                 {
                 ShapelessOreRecipe recipe = (ShapelessOreRecipe)tmpRecipe;
                         recipeResult = recipe.getRecipeOutput();
                 }
                 if (ItemStack.areItemStacksEqual(resultItem, recipeResult))
                 {
                         System.out.println("MODID Removed Recipe: " + recipes.get(scan) + " -> " + recipeResult);
                         recipes.remove(scan);
                 }
         }
}

 

How to remove the recipe (within pre init):

@EventHandler
public void preLoad(FMLPreInitializationEvent event) {
     this.removeRecipe(new ItemStack(Item.doorWood, 1)); //Must be a vanilla recipe
}

<snip code>

 

Why do you check for the various subclasses of recipes (shaped, shapeless, shapedore, shapeless ore)? I ran into a problem with that, in that some recipes are none of the above (swords and pickaxes, e.g.)

 

public static void removeRecipe(ItemStack resultItem)
{
         ItemStack recipeResult = null;
         ArrayList recipes = (ArrayList) CraftingManager.getInstance().getRecipeList();
         for (int scan = 0; scan < recipes.size(); scan++)
         {
                 IRecipe recipe = (IRecipe) recipes.get(scan);
                         recipeResult = recipe.getRecipeOutput();
                 
                 if (ItemStack.areItemStacksEqual(resultItem, recipeResult))
                 {
                         System.out.println("MODID Removed Recipe: " + recipes.get(scan) + " -> " + recipeResult);
                         recipes.remove(scan);
                 }
         }
}

 

Going at it from that angle hasn't caused me any issues so far, and let me replace pickaxe and sword recipes, where the if/else checks missed those cases. Is there something I'm missing that could cause a problem using the simpler approach?
