Registering Entities (1.16.5)

tal124 · March 16, 2021

I thought that registering Entities would be similar to the other ways I have registered Items or Fluids, The tutorials I have seen to do this are both easier, and more difficult than the DeferredRegister's way in 1.16. I have created a Slime Entity called EntityChocolateSlime, but I am unsure as to how I should register it

public class ModEntities{

    public static final DeferredRegister<EntityType<?>> ENTITIES = DeferredRegister.create(ForgeRegistries.ENTITIES, chocolate.MODID);

    //Attaches the deferred register to the event bus
    public static void init() {
        ENTITIES.register(FMLJavaModLoadingContext.get().getModEventBus());
    }




    public static final EntityType<?> CHOCOLATE_SLIME =
            ENTITIES.register("chocolate_slime", EntityType.Builder.<EntityChocolateSlime>create(EntityChocolateSlime::new,
                    EntityClassification.MONSTER).size(2.04F, 2.04F).trackingRange(8));


}

The error message I get is

error: method register in class DeferredRegister<T> cannot be applied to given types;
ENTITIES.register("chocolate_cube", EntityType.Builder.<EntityChocolateSlime>create(EntityChocolateSlime::new,
^

Why can it not be applied?

The register method takes a supplier.

I have registered the Entity but the game doesn't recognize it, however I can start it up, and I have created both the required renderer and model for my Entity called Chocolate_Slime

However it gives me the error "MCP Entity class missing World constructor now"

I have tried copying and pasting and changing the magma cubes to match my chocolate slime however it still gives me this error, I have since reverted it back to what I had originally.

What am I missing?

Here is my Entity Code, And nothing is wrong with my spawnegg either, I changed it from my mod entity to a regular slime and it worked fine

I'm just a little confused and looking at what other mod creators have done with 1.16 entities is a little bit hard since all of them are incredibly more proficient at modding than me.

    }

Right here

I am getting the MCP entity class missing world constructor for some reason and no matter what I do, I can't get it to go away, even straight ripping off the Magma slime entity won't get rid of it.

tal124 · March 16, 2021

The game runs fine, but the Entities just won't exist and no matter how much I look into other mods and adjust my code test it, and then reset it back to where I want it.

tal124 · March 16, 2021

I have all of my current code here https://github.com/Tyrannys/Chocolate, if that's what you mean? I'm relatively new to modding only started a couple weeks ago.

The code you posted does not even compile. After commenting out the data generator code that didn't compile, the game crashes with a null pointer exception in your registration code.

I may have committed the wrong code as I just put it into github a couple of hours ago to organize the mod a bit, Try my test branch and see if that works better, I just committed to it what I currently have.

Its not letting me commit for some reason, I'll fix it and then let you know when it commits

tal124 · March 16, 2021

I made a new commit and switched the other one to private https://github.com/Tyrannys/Chocolate-Mod, don't know why it wouldn't let me push a commit

tal124 · March 16, 2021

There were a lot of changes that I made when adding new blocks, apparently they didn't stick. I'll change it to where I had it. give me a few minutes

tal124 · March 16, 2021

Alright I made the changes and now the code should work just fine. I'm not sure why it reset it back to 2 hours ago.

tal124 · March 16, 2021

So what code should I use instead? I know you probably want me to figure this out on my own, but I've been looking at this code for almost a week now while working on other parts of the mod as well.

tal124 · March 16, 2021

public static final DeferredRegister<Block> BLOCKS = DeferredRegister.create(ForgeRegistries.BLOCKS, chocolate.MODID);
  
  
  public static final RegistryObject<Block> CHOCOLATE_ORE = BLOCKS.register("chocolate_ore", () ->
            new Block(AbstractBlock.Properties.create(Material.ROCK).hardnessAndResistance(3.0F, 3.0F)
            .sound(SoundType.STONE).harvestLevel(1).harvestTool(ToolType.PICKAXE))
        );

This is how I register them,

public static final DeferredRegister<EntityType<?>> ENTITIES = DeferredRegister.create(ForgeRegistries.ENTITIES, chocolate.MODID);

public static final EntityType<EntityChocolateSlime> CHOCOLATE_SLIME = ENTITIES.register("chocolate_slime", ()->
       /*right here*/     );

Its simple with the blocks as you can define a new Block(properties), but new EntityType<> doesn't work the right way either, is there something im missing?

tal124 · March 16, 2021

Its telling me It has private access and I'm not sure how to get around that yet.

You already created an EntityType in your previous code.

Then I suppose im still a little confused, I've typed it out a few different ways and it always comes back with an error

public static EntityType<EntityChocolateSlime> CHOCOLATE_SLIME = ENTITIES.register("chocolate_slime", ()->
            new EntityType.Builder(EntityChocolateSlime::new, EntityClassification.MONSTER).size(2.04F,2.04F).trackingRange(8));

This is what I keep coming back to though, however EntityType.Builder errors out.

tal124 · March 16, 2021

public static final EntityType<EntityChocolateSlime> CHOCOLATE_SLIME = ENTITIES.register(EntityNames.CHOCOLATE_SLIME,()-> EntityChocolateSlime::new, 
            EntityClassification.MONSTER, 2.04F, 2.04F);

Like this?

DietmarKracht · March 16, 2021

I think what you are missing is the actual function to build your entity type. Just add .build() and it should be fine. Also dont use static initializers as @diesieben07 already said. Use RegistryObjects instead.

Here is an example of how i register entity types:

public static RegistryObject<EntityType<EntityItemUpgradable>> ENTITY_UPGRADABLE = ALL.register("upgradable_type",
        () -> EntityType.Builder.<EntityItemUpgradable>create(EntityItemUpgradable::new, EntityClassification.MISC)
                .build(new ResourceLocation(Main.MODID, "upgradable_type").toString()));

                .build(new ResourceLocation(Main.MODID, "upgradable_type").toString()));

Thank you for the sample but now its simply saying my registry object isn't present, the code pushes out, but it says NullPointerException: Registry Object not present: chocolate:chocolate_slime

I updated it

DietmarKracht · March 16, 2021

You need to paste your stacktrace when you get NPEs. The NPE might be due to calling the entity type before it was registered.
