Base Library/API for Dillon's mods.

Cross-platform API providing resuable utilities, such as platform abstraction, mixin management, configuration systems, factories, and other common modding utilities.

---

Developer Notes

Provides all information required to create a mod on multiple modding platforms (ex. Fabric, Forge and NeoForge).

Provides other resources, including:

• Factories, which auto-registers certain behaviors for certain types of objects
• Memory-stored player data, based on UUID
• Easy-to-use mixin predicates
• Scheduled tasks that run within the Minecraft server tick
• Simple permissions getter
• Tick calculators
• A clean options system
• Common texts
• Common client-side operations and modern-styled widget lists

DillonLib does not require any other outside resources or mods, other than Fabric API for fabric users.

You can view the source code for all features and utilities, as well as read documentation below.

To use this library with your mod, add this to your build.gradle file:

repositories {
    exclusiveContent {
        forRepository {
            maven {
                name = "Modrinth"
                url = "https://api.modrinth.com/maven"
            }
        }
        filter {
            includeGroup "maven.modrinth"
        }
    }
}

dependencies {
    implementation "maven.modrinth:dillon-lib:*DL_version*"
    
    // Note: for *DL_version*, make sure you use the correct MC and platform (fabric/neoforge/forge) version.
    // You can get it by opening the specified version and copying the end of the modrinth link.
    // Example: /mod/dillon-lib/version/5voax3wu <- use "5voax3wu" as the *DL_version*!
}

Platform Abstraction

This API provides a versatile way to store your mod's basic information with the help of a built-in Java feature called Service Loaders.

You can think of a service loader as your mod's base entrypoint, or table of contents. The service loader contains information like your mod version, mod ID, platform name (fabric, neoforge, forge, or other), platform release (stable, beta or alpha), and other useful utilities.

DillonLib provides three different service loaders for you to create. One for your base entrypoint (called ModPlatform.class), one specifically designed for mixins (called MixinModPlatform.class), and one for client-side operations (called ClientModPlatform).

You technically do not need to create all platforms. However, you should. Each platform contains necessary information required to register certain things.

Click here to view ModPlatform.class.

Click here to view ClientModPlatform.class.

Click here to view MixinModPlatform.class.

These platforms are designed to work on projects that are coded on multiple mod loaders, so each mod loader should have its own platform classes.

To properly create your service loader, simply create instances of these platform classes, and fill in your information.

Then, in your mods resources folder, create a directory called META-INF/services, and then create the following three files, with these exact names:

net.dillon.dillonlib.platform.client.ClientModPlatform
net.dillon.dillonlib.platform.mixinsafe.MixinModPlatform
net.dillon.dillonlib.platform.ModPlatform

In each of these files, you should enter in the path to your platform. For example, inside of net.dillon.dillonlib.platform.ModPlatform should be:

net.dillon.quesoexample.platform.QuesoExamplePlatformImpl

Then you should create getter classes to get each of your platforms. View an example of this here.

There are three different platforms to ensure that Minecraft launches safely. We don't want client-side interfering with common code, and we also don't want classes to be loaded too early during mixin initialization, which is why we have a separate platform called MixinModPlatform.

Factories

Factories allow you to create certain objects, such as items, boats and keybinds without the headache of registering miscellaneous behaviors for those items.

As seen in the MixinModPlatform class, in order to use factories, you must override the "shouldApplyFactories" method in your MixinModPlatformImpl! Otherwise, the factories will not do what they are supposed to do.

Typically, for example, when you create a ShearsItem, you have to manually mixin certain classes to allow the shears to work properly on certain entities and blocks. Additionally, the shears don't work correctly as a shear predicate on certain loot tables, such as leaves and grass, and their dispenser behavior is never accounted for.

Factories handles this type of stuff for you. All you have to do is create an instance of, in this example, ShearsFactory, and the rest of the behavior will automatically be registered for you.

Here is an example:

public static final Item QUESO_SHEARS = ItemsInvoker.registerModItem(QuesoItemIds.QUESO_SHEARS, ShearsFactory::new, new Item.Properties()
            .component(DataComponents.TOOL, ShearsItem.createToolProperties())
            .rarity(Rarity.UNCOMMON)
            .durability(150)
    );

You don't have to do anything else with your shears after this. Everything else is automatically registered!

You can use factories with the following objects:

• Shears
• Flint and Steels
  • In 1.21.11 and below, dispenser behavior must be done manually for this factory.
• Any "ignitable" item, which ignites or creates fire on certain blocks
• Bows and crossbows
• Boats (1.21.11 and above only)
• Shields
• Totems of Undying
• Keybinds

Boat Factories

Boat factories are a special type of factory that hold "BoatData", which contains all information required for the boat.

The special part about boat factories is that model registration is automatically created for you. All you have to do is create your boat texture and place it in the correct location!

Here is an example of two boat factories, one chest boat, and one non-chest boat:

// QuesoItems.class (boat items)
public static final Item QUESO_BOAT = ItemsInvoker.registerModItem(QuesoItemIds.QUESO_BOAT, properties -> new BoatItem(QuesoEntityTypes.QUESO_BOAT, properties));

public static final Item QUESO_CHEST_BOAT = ItemsInvoker.registerModItem(QuesoItemIds.QUESO_CHEST_BOAT, properties -> new BoatItem(QuesoEntityTypes.QUESO_CHEST_BOAT, properties));

// QuesoEntityTypes.class (boat entities)
public static final EntityType<Boat> QUESO_BOAT = Factories.registerBoatFactory(
            Identifier.fromNamespaceAndPath(QuesoExampleMod.MOD_ID, "queso_boat"), () -> QuesoTestItems.QUESO_BOAT, false);

    public static final EntityType<ChestBoat> QUESO_CHEST_BOAT = Factories.registerBoatFactory(
            Identifier.fromNamespaceAndPath(QuesoExampleMod.MOD_ID, "queso_chest_boat"), () -> QuesoTestItems.QUESO_CHEST_BOAT, true);

You should register the boat entities and items in different classes, failure to do so could result in a compilation error.

Method signature(s) for registering boat factories:

// Typically, you would always use this method
<T extends AbstractBoat> EntityType<T> registerBoatFactory(Identifier id, Supplier<Item> dropItem, boolean chest)

// You should only use this method if you want a custom EntityFactory for your boat (in most cases, you don't)
<T extends AbstractBoat> EntityType<T> registerBoatFactory(Identifier id, Supplier<Item> dropItem, EntityType.EntityFactory<T> factory, boolean chest)

Totem Factories

Totems are hard to duplicate in modding. Totem factories make this process a lot easier. All you have to do is create an instance of TotemFactory, and your totem will work as a normal totem of undying, like normal.

Additionally, you can create custom totem logic that is applied when your totem is used. For example:

public class QuesoTotemFactory extends TotemFactory {

    public QuesoTotemFactory(Properties properties, DeathProtection protection, ParticleOptions particle, int particleLifeTime) {
        super(properties, protection, particle, particleLifeTime);
    }

    // This method is called when your totem is used. See the original TotemFactory for the super method
    // If you don't want custom logic, you don't have to override this method
    @Override
    public void invokeTotemUse(LivingEntity living, ItemStack stack, DamageSource source) {
        /* your custom logic goes here */
    }
}

// QuesoItems.class (create the totem factory)
 public static final Item QUESO_TOTEM = ItemsInvoker.registerModItem(QuesoItemIds.QUESO_TOTEM, properties -> new QuesoTotemFactory(properties, DeathProtection.TOTEM_OF_UNDYING, ParticleTypes.ANGRY_VILLAGER, 30));

As you can see, you can set the particles that appear when using the totem, and set the particle lifetime (the last parameter).

There are two constructors for TotemFactories:

// Default factory, which uses default particles and particle lifetime
public TotemFactory(Properties properties, DeathProtection protection)

// Custom factory
public TotemFactory(Properties properties, DeathProtection protection, ParticleOptions particle, int particleLifeTime)

Other Factories

For other factories, registering them is similar to these other factories. Take a deeper look at this Example Items Class for a better understanding of how to create your factories.

• For shear factories, dispenser behavior, block predicates and use-on entities is automatically registered.
• For flint and steel and ignitable factories, dispenser behavior and use-on entities is automatically registered.
• For bow and crossbow factories, player model and Fov modification is automatically registered.

Mixin Plugin Util

Mixins are high in causing mod incompatibility, and that is what the MixinPluginUtil class is for. It allows you to easily control if mixins certain should be applied at initialization or not.

Click here to view MixinPluginUtil.class.

Example use of MixinPluginUtil.

Once you create your MixinPluginUtil, you can use it like this in your IMixinConfigPlugin:

public class ConditionalMixinPlugin implements IMixinConfigPlugin {

    @Override
    public boolean shouldApplyMixin(String targetClassName, String mixinClassName) {
        DillonLibMixinPluginUtil mixinPluginUtil = new DillonLibMixinPluginUtil();
        return !mixinPluginUtil.shouldNotApply(targetClassName, mixinClassName);
    }
