[1.16.5] Entity Rendering

[tal124]

I have gotten my entity to register and got its attributes to also register, but now I am having issues with the rendering of it.

I made a Renderer class for my entity

@OnlyIn(Dist.CLIENT)
public class ChocolateSlimeRenderer extends MobRenderer<EntityChocolateSlime, ChocolateSlimeModel<EntityChocolateSlime>> {
    private static final ResourceLocation TEXTURE = new ResourceLocation(chocolate.MODID, "textures/entity/chocolate_slime.png");

    public ChocolateSlimeRenderer(EntityRendererManager renderManagerIn) {
        super(renderManagerIn, new ChocolateSlimeModel<>(16), 0.25F);
        this.addLayer(new ChocolateSlimeGelLayer<>(this));
    }
    @Override
    public void render(EntityChocolateSlime entityIn, float entityYaw, float partialTicks, MatrixStack matrixStackIn, IRenderTypeBuffer bufferIn, int packedLightIn) {
        this.shadowSize = 0.25F * (float)entityIn.getSlimeSize();
        super.render(entityIn, entityYaw, partialTicks, matrixStackIn, bufferIn, packedLightIn);
    }
    @Override
    protected void preRenderCallback(EntityChocolateSlime entitylivingbaseIn, MatrixStack matrixStackIn, float partialTickTime) {
        float f = 0.999F;
        matrixStackIn.scale(0.999F, 0.999F, 0.999F);
        matrixStackIn.translate(0.0D, (double)0.001F, 0.0D);
        float f1 = (float)entitylivingbaseIn.getSlimeSize();
        float f2 = MathHelper.lerp(partialTickTime, entitylivingbaseIn.prevSquishFactor, entitylivingbaseIn.squishFactor) / (f1 * 0.5F + 1.0F);
        float f3 = 1.0F / (f2 + 1.0F);
        matrixStackIn.scale(f3 * f1, 1.0F / f3 * f1, f3 * f1);
    }
    @Nullable
    @Override
    public ResourceLocation getEntityTexture(EntityChocolateSlime entity) {
        return TEXTURE;
    }
}

And I thought my issue was pulling from the base Slime Models too so I translated their classes over too and are pretty much exact from the SlimeModel and SlimeGelLayer code.

The game will start, and I can join my SP world, but the moment the world generates it crashes.

• Do not use @OnlyIn.
• You have not registered your renderer.

And how would I register it? All I really understand is the deferred register method, and that wasn't working with whatever I put into it.

Check out RenderingRegistry and its methods.

(Basically call RenderingRegistry::registerEntityRenderingHandler during FMLClientSetupEvent)

This sounds concerning. How are you registering everything then?

All I have are basic blocks, Items, and fluids, so I haven't needed anything else as of yet. And thank you, That actually let me Mob spawn into existence.

It is preferred that blocks, items and entities are registered via DeferredRegistry.

Can you post your code regarding the DeferredRegistry that you said didn't work?

I meant that I was trying to register my rendering handler with DeferredRegistry, and I knew that wouldn't work cause there isn't any code referring to rendering so I tried finding a Registry for rendering, and I guess I skimmed over RenderingRegistry.

And other than that, they pretty much look like this
 

	public static final DeferredRegister<Block> BLOCKS = DeferredRegister.create(ForgeRegistries.BLOCKS, chocolate.MODID);

        public static void init() { BLOCKS.register(FMLJavaModLoadingContext.get().getModEventBus()); }

That should be fine. I thought you meant that the DeferredRegistry isn't working for the IRegistries
