Model Loader does not work

[Zemelua]

I made the following code, but the actual block is displayed as a missing texture. What's wrong?Regietring is complete and works fine.

public class VariantsTextureModel implements IModelGeometry<VariantsTextureModel> {
	private JsonArray variants;

	public VariantsTextureModel(JsonArray variants) {
		this.variants = variants;
	}

	@Override
	public IBakedModel bake(IModelConfiguration owner, ModelBakery bakery, Function<RenderMaterial, TextureAtlasSprite> spriteGetter, IModelTransform modelTransform, ItemOverrideList overrides, ResourceLocation modelLocation) {
		return new BakedModel(variants);
	}

	@Override
	public Collection<RenderMaterial> getTextures(IModelConfiguration owner, Function<ResourceLocation, IUnbakedModel> modelGetter, Set<Pair<String, String>> missingTextureErrors) {
		return null;
	}

	public static final class BakedModel implements IBakedModel {
		private JsonArray variants;

		public BakedModel(JsonArray variants) {
			this.variants = variants;
		}

		@Override
		public List<BakedQuad> getQuads(@Nullable BlockState state, @Nullable Direction side, Random rand) {
			Collection<Property<?>> properties = state.getProperties();
			for (JsonElement variantElement : variants) {
				String JSONVariants = variantElement.getAsString();
				String[] JSONProperties = JSONVariants.split(",", 0);
				for (String JSONProperty : JSONProperties) {
					String propertyName = JSONProperty.split("=", 1)[0];
					Integer propertyValue = Integer.valueOf(JSONProperty.split("=", 1)[1]);
					for (Property<?> property : properties) {
						if (!property.getName().equalsIgnoreCase(propertyName) && state.get(property) == propertyValue) {
							return null;
						}
					}
				}
				TextureAtlasSprite spriteTop = new RenderMaterial(AtlasTexture.LOCATION_BLOCKS_TEXTURE, new ResourceLocation(variantElement.getAsJsonObject().get("top").getAsString())).getSprite();
				BakedQuadBuilder builder = new BakedQuadBuilder();
				builder.setTexture(spriteTop);
				List<BakedQuad> quads = new ArrayList<BakedQuad>();
				quads.add(builder.build());
				return quads;

			}
			return null;
		}

		@Override
		public boolean isAmbientOcclusion() {
			return false;
		}

		@Override
		public boolean isGui3d() {
			return false;
		}

		@Override
		public boolean isSideLit() {
			return false;
		}

		@Override
		public boolean isBuiltInRenderer() {
			return false;
		}

		@Override
		public TextureAtlasSprite getParticleTexture() {
			return null;
		}

		@Override
		public ItemOverrideList getOverrides() {
			return null;
		}
	}

	public static class Loader implements IModelLoader<VariantsTextureModel> {
		public static OBJLoader INSTANCE = new OBJLoader();

		@Override
		public void onResourceManagerReload(IResourceManager resourceManager) {

		}

		@Override
		public VariantsTextureModel read(JsonDeserializationContext deserializationContext, JsonObject modelContents) {
			JsonArray variants = new JsonArray();
			if (modelContents.has("variants")) {
				variants = modelContents.getAsJsonArray("variants");
			}
			return new VariantsTextureModel(variants);
		}
	}
}

 

JSON model:

{
	"parent": "block/oak_planks",
	"loader": "expansionmod:variants-texture",
	"variants": {
		"x_width=0,z_width=0": {
			"top": "minecraft:block/oak_planks"
		}
	}
}

sorry. It was a really stupid mistake. I rewrote it this way, but it crashes with Caused by: java.lang.IllegalStateException: not enough data.

To be honest, I only understand that Baked Quad is a class that represents a face with four vertices, and I know I need to put something, but what exactly do I do? I don't know what to do. What is the list of BakedQuads and what is each BakedQuad? I would like to know in as much detail as possible. I'm sorry to ask you many times.

With further changes, it looks like this. Before the fix, it crashed when I opened the world, but it's gone. However, the texture of the block remains transparent and when destroyed it crashes with a net.minecraft.crash.ReportedException: Rendering Particle. What's wrong?

[Zemelua]

I pondered it, but I still don't know much about Baked Quad ...
Perhaps SimpleBakedModel.Builder only creates a completely empty BakedModel, setTexture only specifies the texture of the particles, and the texture of each face needs to be specified in BakedQuad. After creating an instance of BakedQuadBuilder in order to generate BakedQuad, I understand that it is necessary to put vertex data by put, but what value is passed as to how the vertex data is defined? I don't know how it will be modeled. I also searched for a tutorial on this, but couldn't find it, and I'm completely out of luck. Please Please Please give me a detailed explanation!

Good news! I looked up various vanilla code, existing mod code, etc. and managed to code to this state. However, at present, both the north and south sides are displayed facing north when viewed from the north side, and both sides are not displayed when viewed from the south side. In other words, the south side is not behaving correctly. In the code above,

`quads.add (buildQuad (Direction.SOUTH, sprite, sprite,
0, 0, 1, sprite.getMinU (), sprite.getMaxV (),
0, 1, 1, sprite.getMinU (), sprite.getMinV (),
1, 1, 1, sprite.getMaxU (), sprite.getMinV (),
1, 0, 1, sprite.getMaxU (), sprite.getMaxV ()
));`

Which value should be changed to render correctly?
