Setting Up Your Improvement Surroundings and Venture
Dependency Administration
Earlier than diving into JEI integration, it’s good to guarantee your growth surroundings is appropriately arrange. This includes organising your modding surroundings, together with the suitable IDE (like IntelliJ IDEA), the proper Minecraft Forge or Material growth surroundings, and a well-structured challenge. That is the elemental groundwork on your mod.
The center of profitable JEI integration lies in correct dependency administration. This implies together with the JEI API as a dependency in your challenge’s construct file. That is typically a `construct.gradle` file for those who’re utilizing Gradle or the same configuration file relying in your growth device. Making certain your challenge appropriately references the JEI API allows you to use its courses and strategies. Failing to declare this dependency will depart you stranded and your integration efforts unsuccessful.
A fundamental dependency setup in a `construct.gradle` (Groovy DSL) would look one thing like this:
dependencies {
// Your mod's dependencies
implementation 'internet.minecraftforge:forge:' // Change together with your forge model
// JEI Dependency - Add the correct model suitable together with your Minecraft model.
implementation 'mezz.jei:jei:' // Change with the proper JEI model.
}
It is crucial that the JEI model you select is suitable with each your Minecraft model and your chosen mod loader (Forge or Material). Mismatched variations are a standard supply of issues when integrating JEI into your mod. All the time seek the advice of the official JEI documentation and boards for model compatibility matrices.
Configuration and Initialization
The first mechanism for integrating with JEI is thru an `IModPlugin`. This can be a essential part that tells JEI easy methods to interface together with your mod. Your plugin is basically a bridge, enabling JEI to entry your mod’s objects, recipes, and classes.
To make use of it, you create a category that implements the `IModPlugin` interface. This class turns into your central level of interplay with JEI. That you must inform JEI about this plugin in order that it is aware of to make use of it. That is usually completed throughout the initialization of your mod, just like the `ModSetupEvent` or an equal mod loading part.
In your `ModInitializer` or equal entry level on your mod loader, you’d name `JEIPlugin.register()` like so.
@Mod("yourmodid")
public class YourMod {
public YourMod() {
IEventBus bus = FMLJavaModLoadingContext.get().getModEventBus();
// ... different mod setup ...
bus.register(this); //Register the occasion bus
MinecraftForge.EVENT_BUS.register(this);
FMLJavaModLoadingContext.get().getModEventBus().register(new JEIPlugin()); //Register the JEI Plugin
}
// ... remainder of your mod code ...
}
Crafting Your JEIPlugin Class
Your `JEIPlugin` class will implement the `IModPlugin` interface. This interface requires you to implement a number of strategies, most notably:
- `registerCategories()`: That is the place you register the recipe classes utilized by your mod. Classes are used to arrange recipes inside JEI (e.g., crafting, smelting, and many others.).
- `registerRecipes()`: That is the place you register all of the recipes out of your mod. You inform JEI about what inputs, outputs, and crafting necessities there are.
- `registerIngredients()`: This technique registers your entire mod’s customized ingredient sorts, you probably have any past the usual ones like `ItemStack` and `FluidStack`.
A fundamental construction of your `JEIPlugin` class appears like this:
@JEIPlugin
public class JEIPlugin implements IModPlugin {
@Override
public void registerCategories(IRecipeCategoryRegistration registration) {
// Register your recipe classes right here
}
@Override
public void registerRecipes(IRecipeRegistration registration) {
// Register your recipes right here
}
@Override
public void registerIngredients(IModIngredientRegistration registration) {
// Register your customized components right here, you probably have any
}
@Override
public ResourceLocation getPluginUid() {
return new ResourceLocation("yourmodid", "jeiplugin");
}
}
Troubleshooting Configuration Issues
- Plugin Not Loading: In case your plugin does not appear to be registering, examine your logs for errors. Guarantee your `IModPlugin` implementation is appropriately registered with the occasion bus. Make sure the JEI API dependency is correctly included. Double-check the model compatibility of JEI together with your Minecraft model and mod loader.
- Class Loading Points: Guarantee your plugin class is in a location that is accessible by the mod loader. Double-check package deal names for typos.
- Kind Mismatches: The registration strategies take parameters like `IRecipeRegistration` and `IRecipeCategoryRegistration`. Make certain your code makes use of the suitable sorts and avoids any class casting points.
Registering Gadgets and Substances
After getting your plugin arrange, the following step includes registering your mod’s objects and components with JEI.
The Significance of Merchandise Registration
That is the cornerstone of your JEI integration. With out appropriately registering objects and components, they will not present up in JEI, and gamers will not be capable to see recipes that use them.
Ingredient Sorts
JEI helps a number of ingredient sorts out of the field. The commonest are:
- `ItemStack`: Represents an ordinary merchandise and stack.
- `FluidStack`: Represents a fluid.
You’ll be able to create your personal customized components you probably have particular wants, however we’ll discover that later.
Here is a fundamental instance of the way you may register an `ItemStack` inside your `registerIngredients()` technique.
@Override
public void registerIngredients(IModIngredientRegistration registration) {
registration.getIngredientTypes().forEach(ingredientType -> {
if (ingredientType == VanillaTypes.ITEM_STACK) {
registration.register(
VanillaTypes.ITEM_STACK,
Listing.of(new ItemStack(YourMod.yourItem)),
VanillaTypes.ITEM_STACK.getUid()
);
}
});
}
Be sure that the `YourMod.yourItem` is a sound merchandise occasion. Additionally, don’t forget that you simply additionally must import all of the required courses.
Troubleshooting Merchandise Registration Issues
- Gadgets Not Showing: This can be a widespread drawback. First, ensure that your objects are literally registered with Minecraft. Then, confirm that you’ve got appropriately registered them with JEI within the `registerIngredients` technique. Double-check your merchandise IDs and the merchandise objects you are passing.
- Incorrect Merchandise Properties: This may occur for those who do not appropriately affiliate the merchandise properties in your registration with JEI. Make certain to affiliate the show identify, textures, and another related info to your merchandise in the proper locations.
- Lacking Textures: JEI makes use of the textures outlined on your objects in Minecraft. Guarantee your textures are situated within the right folder and that your merchandise mannequin is appropriately outlined. Confirm there are not any typos within the file names or paths.
Recipe Dealing with
Now that your objects are registered, the main target shifts to exhibiting your mod’s recipes in JEI.
Understanding Recipes
Recipes outline the method of how gamers can acquire your mod’s objects. They specify components, crafting necessities, and output objects. Totally different recipe sorts exist: Crafting, Smelting, Brewing, and many others.
Registering Recipe Classes
Recipe classes are essential for organizing recipes inside JEI. They visually group comparable recipes collectively. For example, crafting recipes go below the “Crafting” class. To register a class, it’s good to create an `IRecipeCategory`.
Here is easy methods to create a recipe class.
public class YourRecipeCategory implements IRecipeCategory<YourRecipe> {
personal remaining IDrawable background;
personal remaining IDrawable icon;
personal remaining Element localizedName;
personal static remaining ResourceLocation GUI = new ResourceLocation("yourmodid", "textures/gui/jei_gui.png"); // instance
public YourRecipeCategory(IGuiHelper guiHelper) {
this.localizedName = Element.translatable("yourmodid.jei.class.yourrecipe"); // Use the interpretation key for the identify.
this.icon = guiHelper.createDrawableIngredient(new ItemStack(YourMod.yourItem)); // Use your merchandise as an icon.
this.background = guiHelper.createDrawable(GUI, 0, 0, 160, 80); // Your GUI background (regulate dimensions as wanted).
}
@Override
public ResourceLocation getUid() {
return new ResourceLocation("yourmodid", "yourrecipe"); //Distinctive identifier.
}
@Override
public Class<? extends YourRecipe> getRecipeClass() {
return YourRecipe.class; //The recipe class to be proven.
}
@Override
public Element getTitle() {
return this.localizedName; //Present your translation key.
}
@Override
public IDrawable getBackground() {
return this.background; //Present your GUI background
}
@Override
public IDrawable getIcon() {
return this.icon; //Present the icon on the sidebar.
}
@Override
public void draw(YourRecipe recipe, IRecipeSlotsView recipeSlotsView, PoseStack poseStack, double mouseX, double mouseY) {
IRecipeCategory.tremendous.draw(recipe, recipeSlotsView, poseStack, mouseX, mouseY);
}
@Override
public void setRecipe(IRecipeLayoutBuilder builder, YourRecipe recipe, IFocusGroup focuses) {
// Create slots for components and outputs.
}
}
And in your `registerCategories` technique, register the class.
@Override
public void registerCategories(IRecipeCategoryRegistration registry) {
registry.addRecipeCategories(new YourRecipeCategory(registry.getJeiHelpers().getGuiHelper()));
}
Registering Recipes
Registering recipes is the core of creating your mod’s recipes seen in JEI. That is completed inside the `registerRecipes` technique.
@Override
public void registerRecipes(IRecipeRegistration registration) {
registration.addRecipes(new ResourceLocation("yourmodid", "yourrecipe"), Listing.of(new YourRecipe())); //Register YourRecipe class.
}
This straightforward instance assumes you could have created a `YourRecipe` class which shops your recipe info.
You’ll be able to register many alternative recipe sorts, from crafting desk recipes to furnace smelting recipes.
Troubleshooting Recipe Issues
- Recipes Not Showing: The commonest problem. Double-check:
- That you’ve got registered the recipe with JEI.
- That your class is registered.
- That each one components are appropriately registered.
- That your recipe’s knowledge (components, outputs) is right.
- Incorrect Substances/Outputs: Confirm the components and outputs in your recipe implementation. Ensure you will not be utilizing the inaccurate cases or portions.
- Recipe Show Points: Make sure the recipe structure is right. In case you are utilizing customized classes, confirm the background texture is appropriately sized and situated.
Recipe Class and Ingredient Renderers
You’ll be able to customise how your recipes look in JEI.
Customizing the Recipe Class
You management how the recipes of the class look. For instance, the icons and background of the recipe class. You should use the `IRecipeCategory` to customise these features.
Ingredient Renderers
Ingredient Renderers are used to show the components. JEI gives default renderers for a lot of ingredient sorts.
Superior Strategies and Optimization
Whereas the fundamentals cowl a lot of the integration, sure superior methods and optimization methods can additional enhance your mod.
Implementing Customized JEI Substances
In case your mod makes use of specialised ingredient sorts past fundamental objects or fluids, you want customized components and renderers.
Filtering/Hiding Gadgets and Recipes
Generally you may need to cover objects or recipes. This may be helpful to cover sure developmental or testing objects.
@Override
public void registerRecipes(IRecipeRegistration registration) {
registration.getRecipeManager().hideRecipe(new ResourceLocation("yourmodid", "hidden_recipe")); // Instance: Conceal a recipe
}
Efficiency Concerns
JEI integration can influence efficiency. Optimize your code by utilizing caching, avoiding pointless computations, and environment friendly knowledge constructions.
Widespread Issues and Options
Let’s revisit some recurring points with options.
- JEI Not Loading: Guarantee you could have the JEI API dependency. Examine your logs for any startup exceptions.
- Gadgets or Recipes Lacking: Confirm correct registration. Examine for typos. Guarantee your mod’s initialization and recipe registration is full.
- Incorrect Data: Double-check merchandise and recipe knowledge. Evaluate logs for any potential errors.
All through your complete integration course of, overview the logs. It’s an effective way to debug your code.
