[1.16.4]uncaught exception trying to build ShapedRecipes

Posted October 22, 20213 yr

Good morning,

I'm trying to implement ShapedRecipes into my mod via DataGeneration. I'm using vanilla MC code as template, and I'm able to create a single recipe, but the code will fail if I try to build multiple recipes in the same method. Which is a bit confusing, since I pretty much do it exactly as the vanilla code. The code:

	public class DataGenRecipe extends RecipeProvider {
	      public DataGenRecipe(DataGenerator generator) {
        super(generator);
      }
	      @Override
      protected void registerRecipes(Consumer<IFinishedRecipe> consumer) {
          brickBasalt(consumer, RegisterMain.BLOCKBRICKBASALT.get(), RegisterMain.BLOCKBASALTITEM.get());
          brickBluestone(consumer, RegisterMain.BLOCKBRICKBLUESTONE.get(), RegisterMain.BLOCKBLUESTONEITEM.get());
      }
      
      private void brickBasalt(Consumer<IFinishedRecipe> recipeConsumer, IItemProvider output, IItemProvider input) {
          ShapedRecipeBuilder
              .shapedRecipe(output)
              .key('#', input)
              .patternLine("###")
              .patternLine("###")
              .patternLine("###")
              .setGroup("matlibtab")
              .addCriterion("has_item", hasItem(input))
              .build(recipeConsumer);
      }      
      
      private void brickBluestone(Consumer<IFinishedRecipe> recipeConsumer, IItemProvider output, IItemProvider input) {
          ShapedRecipeBuilder
              .shapedRecipe(output)
              .key('#', input)
              .patternLine("###")
              .patternLine("###")
              .patternLine("###")
              .setGroup("matlibtab")
              .addCriterion("has_item", hasItem(input))
              .build(recipeConsumer);
      }           
      
}

The error log:

Oups, sorry, solved. Obviously I'm supposed to provide an object of type item, and not type block.

(((SOLVED))) Loading into certain worlds stuck on "Reading world data" then stops responding.

So, I tried this, and the world did load, but ALL of the modded items and things I had completely disappeared, as well as many unmodded things like my chests and items I was carrying. Any solutions?

How do I remove 3d headlayer on NPC's skin in CustomNpc? (1.16.5)

I do have to add that this is my answer for 1.12.2 but it should ALSO work for future versions.

I know this was posted almost 3 years ago but this is for anyone who is still looking for an answer.

First, find your config folder. -> C:\Users\ (desktop user's name) \curseforge(or the application where you've downloaded you mod)\minecraft\Instances\config (The config folder should be in the same folder as your mods folder.) Once you click on the config folder, search for CustomNpcs.cfg. Once found, click on it (you can edit it using notepad) and search for the line "headweartype". Set the value to 0 if you want a 2d head layer, set it to 1 for a 3d head layer. Then save the options and you should be good to go from there! :)
