[1.14.4] Dynamic block/entity/item etc based on other mods

[MSpace-Dev 12]

Is it possible to get all loaded entities in the registry (from all other mods) at runtime, to then be able to spawn in said entity within my mod? I feel it might be possible now, with how structured the registry events are in 1.14.

I am also trying to generate new entities at runtime based on this by using a builder pattern of sorts.

I assume you mean entity types, not entities. You can find all registries in the ForgeRegistries class, in this case you want ForgeRegistries.ENTITIES.

The EntityType has various methods to create new entities of that type.

I've been doing some research. What are your thoughts on this method?

	@SubscribeEvent
	public static void onRegisterEntities(final RegistryEvent.Register<EntityType<?>> event)
	{
		DeferredWorkQueue.runLater(() -> {
			entityBuilder(event);
		});
	}

	private static void entityBuilder(final RegistryEvent.Register<EntityType<?>> event)
	{
		ArrayList<EntityType<?>> all_entities;
		all_entities = (ArrayList<EntityType<?>>) event.getRegistry().getValues();

		Main.LOGGER.debug("ALL LOADED ENTITIES:");
		all_entities.forEach(p -> Main.LOGGER.debug(p));
	}

 

And will I be able to register new entities under new IDs using the methods within EntityType and ForgeRegistries.ENTITIES? (If I don't go with this method ^)

Well, that actually does not run. DeferredWorkQueue#runLater does not get called.

Don't obtain the entities in that event. Just access the registry directly whenever you need it.

No. New entities must be registered at startup, in the appropriate registry event. You should also not register a dynamic set of entries. Your mod should always register the same things, regardless of configuration or other circumstances.

So, creating new entity types based on other mods is impossible?

It's not impossible, but it is discouraged. Why do you want to do that? What result are you trying to achieve?

[MSpace-Dev 12]

I want to expand my mod's features lots in 1.14.4. I want users to be able to specify mobIDs from other mods in JSON to initialise a new item, block and entity for the specified id. To do this, I need to be able to dynamically create these objects.

 

It would be perfect for my mod. You will be able to see that at a quick glance I think:

Correct, but they do not need to be separate items/blocks/entities.

In this case you would make one item/block/entity which can pose as any other.

How would I achieve something like that roughly? Any suggestions / resources I can look into?

Take entities for example. You would write one entity class. This entity class takes whatever data has been configured in the JSON as a constructor parameter. For example an EntityType combined with some spawn information (e.g. spawn with a sword, or whatever features you want). Then this entity needs to act according to this configuration.

Ah, thanks. I will look into it further tomorrow morning. I have to head off to sleep, but hope I can get something working. Forge 1.14 is a rather large step in the right direction from what I've seen so far!
