[1.15.2] Tile Entity Rendering Help

MattNL · February 10, 2020

So... I'm attempting to make something that may be a bit excessive.

I'm trying to add more skulls to the game. I simply decided to use the existing tile entity in the game... but I'm not sure if this is the right approach. However, that doesn't seem to be the case as both the block and item are registered without an issue... it's only when the game attempts to RENDER it, that it finally crashes. I've tested a little with this by changing the Creeper Head's texture, but nothing changed. I'm not sure if I have to register a new tile entity completely, but if that is the case, I've attempted that already with identical results.

So, I guess what I'm trying to do, is replace the TileEntityRenderer for SkullTileEntity.

Here is the code that I have so far, and hopefully, someone can show me what I'm doing wrong... (which is probably also the WAY I'm doing it)

My TileEntityRenderer (A slightly modified version of Vanilla's SkullTileEntityRenderer):

@OnlyIn(Dist.CLIENT)
public class NewSkullTileEntityRenderer extends TileEntityRenderer<SkullTileEntity> {
	private static final Map<SkullBlock.ISkullType, GenericHeadModel> MODELS = Util.make(Maps.newHashMap(), (p_209262_0_) -> {

		GenericHeadModel genericheadmodel1 = new HumanoidHeadModel();
		DragonHeadModel dragonheadmodel = new DragonHeadModel(0.0F);
		p_209262_0_.put(SkullBlock.Types.SKELETON, genericheadmodel);

	});
	private static final Map<SkullBlock.ISkullType, ResourceLocation> SKINS = Util.make(Maps.newHashMap(), (p_209263_0_) -> {

My Registry:

	}

	public interface ISkullType {

	public static enum Types implements SkullBlock.ISkullType {

}

My (WallSkullBlock is also private) NewWallSkullBlock:

	}

	public BlockState rotate(BlockState state, Rotation rot) {

	}

	protected void fillStateContainer(StateContainer.Builder<Block, BlockState> builder) {

}

My Item Registry:

new SkullItem(ModBlocks.steve_head, ModBlocks.steve_head_wall, (new Item.Properties()).group(ItemGroup.DECORATIONS).rarity(Rarity.UNCOMMON)).setRegistryName("[NAMESPACE HERE]","steve_head"),
new SkullItem(ModBlocks.alex_head, ModBlocks.alex_head_wall, (new Item.Properties()).group(ItemGroup.DECORATIONS).rarity(Rarity.UNCOMMON)).setRegistryName("[NAMESPACE HERE]","alex_head"),

My Block Registry:

steve_head = registerBlock(new NewSkullBlock(NewSkullBlock.Types.STEVE, Block.Properties.create(Material.MISCELLANEOUS).hardnessAndResistance(1.0F)),"[NAMESPACE HERE]","steve_head");
steve_head_wall = registerBlock(new NewWallSkullBlock(NewSkullBlock.Types.STEVE, Block.Properties.create(Material.MISCELLANEOUS).hardnessAndResistance(1.0F)),"[NAMESPACE HERE]","wall_steve_head");
alex_head = registerBlock(new NewSkullBlock(NewSkullBlock.Types.ALEX, Block.Properties.create(Material.MISCELLANEOUS).hardnessAndResistance(1.0F)),"[NAMESPACE HERE]","alex_head");
alex_head_wall = registerBlock(new NewWallSkullBlock(NewSkullBlock.Types.ALEX, Block.Properties.create(Material.MISCELLANEOUS).hardnessAndResistance(1.0F)),"[NAMESPACE HERE]","wall_alex_head");

Sorry for the huge amount of code, but I honestly don't know what's wrong here.

Thanks in advance!

Hey everyone! I'm just gonna give this topic a bump. It's been over a month, and I still haven't got a clue what I'm doing wrong. Thanks in advance!

Howdy

Please include the crash report? That will provide vital clues...

For starters this:

.setRegistryName("[NAMESPACE HERE]","steve_head")

won't work, everything has to be lowercase (and the namespace should be your modid).

Secondly,

it's only when the game attempts to RENDER it, that it finally crashes.

What is the error? Show us your log file.

I tend to censor my namespaces. It's just something that I do. (The namespace is a proper lowercase modid)

Second, I should have posted the crash log before, and that's my bad.

If it helps, these are the item models...

Items (Identical to all other skulls in Vanilla):

{
    "parent": "item/template_skull"
}

Template Skull (Vanilla):

{
    "parent": "builtin/entity",
    "textures": {
        "particle": "block/soul_sand"
    },
    "display": {

            "translation": [ 0, 3, 0 ],

Howdy

This part here

	at java.util.Objects.requireNonNull(Objects.java:203)
	at java.util.Optional.<init>(Optional.java:96)
	at java.util.Optional.of(Optional.java:108)
	at net.minecraft.client.renderer.RenderState$TextureState.<init>(SourceFile:192)

tells me that you are trying to initialise your Renderer with a texture ResourceLocation that is null, i.e. hasn't been set properly.

Looking at your code, I suspect this:

p_209263_0_.put(SkullBlock.Types.PLAYER, DefaultPlayerSkin.getDefaultSkinLegacy());

I would suggest you put a breakpoint in a suitable location and have a look at what the ResourceLocation has been set to.

eg in the put statement above, or in SkullEntityTileRenderer::func_228879_a_

Cheers

I've replaced the function with a texture path instead, but I still got the RenderState$TextureState crash. Perhaps the renderer isn't being registered?

Hmm ok

I suggest you put a breakpoint at that line and see which ResourceLocation exactly is causing the problem

-TGG

uSkizzik · July 1, 2021

So, after tons of rage quitting and a short 2-day break, I figured out what was wrong.
I had the exact same issue and here's the solution for anyone who needs it in the future:

Edit: Yeah, no. My old method isn't correct at all (Thanks to diesieben07 for the help). Just add the code below and it should be fine. You can also change "new GenericHeadModel(0, 0, 32, 32)" to a custom model or you can change the last 2 values to modify the texture size.

	@SubscribeEvent
    public static void registerCustomSkullRenderers(final FMLClientSetupEvent event) {
        Field ModelField;
        Field SkinField;
        try {
            ModelField = SkullTileEntityRenderer.class.getDeclaredField("MODEL_BY_TYPE");
            ModelField.setAccessible(true);
            Map<SkullBlock.ISkullType, GenericHeadModel> Model = (Map<SkullBlock.ISkullType, GenericHeadModel>) ModelField.get(SkullTileEntityRenderer.class);
            Model.put(<Insert Custom Skull Type>, new GenericHeadModel(0, 0, 32, 32));

            SkinField = SkullTileEntityRenderer.class.getDeclaredField("SKIN_BY_TYPE");
            SkinField.setAccessible(true);
            Map<SkullBlock.ISkullType, ResourceLocation> Skin = (Map<SkullBlock.ISkullType, ResourceLocation>) SkinField.get(SkullTileEntityRenderer.class);
            Skin.put(<Insert Custom Skull Type>, new ResourceLocation("<Mod ID>:<Texture Location>"));
        }
        catch (NoSuchFieldException | IllegalAccessException e) {
            e.printStackTrace();
        }
    }

Basically, you have to register a custom item renderer. Let's say the block and the tile entities were done properly (Too lazy to check) and the item (more exactly the texture) was the issue.
All you need to do is add the following two methods to your main project class:

public static Item.Properties setupISTER(Item.Properties group) {
	return group.setISTER(MainClass::getISTER);
}

@OnlyIn(Dist.CLIENT)
public static Callable<ItemStackTileEntityRenderer> getISTER() {
	return ItemRenderer::new;
}

~~and after that you need to add this to your block item:~~

MainClass.setupISTER(new Item.Properties())

Item.Properties() is of course your item properties like tab, rarity and etc.

Then finally you're gonna need your Item Renderer class which should be something similar to this:

@OnlyIn(Dist.CLIENT)
public class ItemRenderer extends ItemStackTileEntityRenderer {
    public static final ItemStackTileEntityRenderer instance = new PA_ItemRenderer();

    @Override
    public void renderByItem(ItemStack stack, ItemCameraTransforms.TransformType transform, MatrixStack matrix, IRenderTypeBuffer renderer, int light, int overlay) {
        Item item = stack.getItem();
        if (item instanceof BlockItem) {
            Block block = ((BlockItem) item).getBlock();
            if (block instanceof AbstractSkullBlock) {
                PA_SkullRenderer.renderSkull(null, 180.0F, ((AbstractSkullBlock) block).getType(), null, 0.0F, matrix, renderer, light);
            }
        }
    }
}

~~The renderer is a slightly modified version of the vanilla one and all the code was made on 1.16.5.~~
