[Solved] Projectile Entity is Invisible


Recommended Posts

My projectile is working completely as intended, but it's invisible for some reason. I think it has something to do with how I'm registering its renderer.

 

Here I'm using an item to spawn it, identical to how a dragon would shoot a fireball: 

 

 

Here's my Registry Object entry:

public static final RegistryObject<EntityType<HeartballEntity>> HEARTBALL_PROJECTILE = ENTITIES.register("heartball", () -> EntityType.Builder.<HeartballEntity>create(HeartballEntity::new, EntityClassification.MISC).size(0.25F, 0.25F).trackingRange(4).func_233608_b_(10).build("heartball"));

Here's the code in my main class that's handling the registry of the rendering:

private void doClientStuff(final FMLClientSetupEvent event)
    {
        registerEntityModels(event.getMinecraftSupplier());
    }

    private void registerEntityModels(Supplier<Minecraft> minecraft)
    {

        EntityRendererManager renderer = minecraft.get().getRenderManager();

        renderer.register(RegistryHandler.HEARTBALL_PROJECTILE.get(), new HeartballRenderer(renderer));

    }

(FMLJavaModLoadingContext.get().getModEventBus().addListener(this::doClientStuff); is called in the constructor.)

 

HeartballEntity and HeartballRenderer are identical to DragonFireballEntity and DragonFireballRenderer for example purposes, with the exception of the texture in HeartballRenderer, which I have changed to a target texture of my own:

private static final ResourceLocation HEARTBALL_TEXTURE = new ResourceLocation(TwoDotXMod.MOD_ID + ":textures/entity/heartball.png");

 

I appreciate any help, let me know if more information is needed.

 

Cheers.

Use RenderingRegistry.registerEntityRenderingHandler to register entity renderers.

I tried this with no luck:

RenderingRegistry.registerEntityRenderingHandler(RegistryHandler.HEARTBALL_PROJECTILE.get(), HeartballRenderer::new);

  • Do not use @OnlyIn.
  • Custom entities must override Entity#createSpawnPacket and call NetworkHooks.getEntitySpawningPacket.
  • Use @Override when overriding methods.

Solved. Removed @OnlyIn from HeartballEntity and added this to the end of my Entity class:

@Override
    public IPacket<?> createSpawnPacket() {
        return NetworkHooks.getEntitySpawningPacket(this);
    }

Thanks for the help,

 

Cheers.
