Universal Registration

Those who have ever written mods for different loaders have probably noticed that each of them has its own unique tools for registering game objects (blocks, items, mobs, etc.) HollowCore allows you not to worry about registering objects for each loader by providing a convenient registration system.

Creating a New Registrar

So, first, create an object class inherited from HollowRegistry, in which all registrations will take place.

Example

object ModItems : HollowRegistry() {

}

Registration of a game object

HollowCore allows you to register almost all game objects. It determines the type of registrar automatically; you need to create a delegate using the register(location: ResourceLocation, () -> T): RegistryObject<T> method, where T is the class of your object.

Example

object ModItems : HollowRegistry() {
    val MY_ITEM by register("modid:my_item".rl) { // .rl is short for ResourceLocation. 
        MyItem() // The object of your item
    }
}

All other game objects are registered in the same way, pass the desired object.

tip

If you don't want to keep specifying modid: for every object you register, you can add your mod id to the HollowRegistry constructor:

object ModItems : HollowRegistry("modid") {
    val MY_ITEM by register("my_item") {
        MyItem() // The object of your item
    }
}

Using Game Objects

Now that the object is registered, you can retrieve it using the <T>RegistryObject.get() method.

Example

fun getMyItem(): MyItem {
    return ModItems.MY_ITEM.get()
}
