[SOLVED] Getting Tile Entities for Crop Type Renderers

In my mod I am trying to make a block that has a render Id of 6 (crops), but also has a TileEntity associated with it to store what growth stage it is in (it is a support structure that can grow different kinds of vines on it). This means that I also want to be able to return a different texture based on the growth stage and type of vine that it is growing. The problem is that in the RenderBlocks class, when it is time to get the texture needed for the icon, all blocks with render type 6 have "getIcon(int, int)" called, which does not allow me to access the TileEntity at the given point and use it to return the proper icon. The method I need is "getBlockTexture(IBlockAccess, int, int, int, int)" since that allows me to access the TileEntity stored at that point, but it is never called for all blocks of render Id 6.

 

I know that you can access the RenderBlocks and therefore its IBlockAccess field using "Minecraft.getMinecraft().renderGlobal.globalRenderBlocks.blockAccess", but there is no way to get the current position that the renderer is rendering at, so I still cant access the proper TileEntity. I have also tried making a custom TESR that just overrides the active texture and then calls the renderBlockCrop() method in RenderBlocks, but then the block appears invisible.

 

My question would be how to get around this without making a new TESR and basically copying the rendering code for crops, which I could do but would like to avoid if possible.

No we specifically made it to have a TileEntity, because there are 4 growth stages (empty, growing, grown, and flowered), as well as we have 6 or 7 different types of vines, with more planned. The empty stage is not tied to a vine type, but every other growth stage is, so that is 3 stages for each of the types of vine. We are also compacting all of them into a single block to save on block ids, and to make it simpler to manage.

BlockIDs are not obsolete, you just have no control of or access to them anymore, and they can also be different per world.

There is still an internal array thus still a limit. (32000 items, including the 4096 blocks)

'Unlimited' never exists, there will ALWAYS be a limit, this one is in place based off the save format.

Don't use more then you need ;)

 

 

As for rendering, you'll need to code a custom renderer.

No need to code it from scratch, you could copy the minecraft code into your own render class and make the needed changes to it.

Hi

 

I'd suggest you stick with one Block per type of vine, with metadata for the growth stage.  The reason I say that is because TileEntities take up a lot more memory and are significantly slower to render if you have a lot of them.  They're also harder to program properly.  If you're worried about keeping your code conceptually simple, you could create a base BlockMyVineBase and derive all your different types of vine from those.

 

If you want to use the TileEntity approach, you can either render your block using a TileEntitySpecialRenderer, or alternatively (similar to your original idea), you can use an ISimpleBlockRenderingHandler, which is given the [x,y,z] when the rendering method is called.  A bit more info here:

      Register custom PlayerRenderer

      By thuggeelya · Posted

      Hi! I'm trying to add my custom models/textures renderer like this: public class PonyPlayerWrapperRenderer extends EntityRenderer<Player> { // wrapper class under my LivingEntityRenderer class implementation private final PonyPlayerRenderer innerRenderer; private final PonyPlayerRenderer innerSlimRenderer; public PonyPlayerWrapperRenderer(final EntityRendererProvider.Context context) { super(context); System.out.println("creating new PonyPlayerWrapperRenderer"); this.innerRenderer = new PonyPlayerRenderer(context, false); this.innerSlimRenderer = new PonyPlayerRenderer(context, true); } @Override public void render(final Player entity, final float yaw, final float partialTicks, final PoseStack poseStack, final MultiBufferSource bufferSource, final int packedLight) { System.out.println("PonyPlayerWrapperRenderer render: " + entity.toString()); if (entity instanceof AbstractClientPlayer clientPlayer) { if (clientPlayer.getModelName().contains("slim")) { innerSlimRenderer.render(clientPlayer, yaw, partialTicks, poseStack, bufferSource, packedLight); } else { innerRenderer.render(clientPlayer, yaw, partialTicks, poseStack, bufferSource, packedLight); } } } @Override public ResourceLocation getTextureLocation(final Player player) { System.out.println("PonyPlayerWrapperRenderer getTextureLocation"); if (player instanceof AbstractClientPlayer clientPlayer) { return clientPlayer.getSkinTextureLocation(); } System.out.println("player instanceof AbstractClientPlayer is false"); return getDefaultSkin(player.getUUID()); } } public class PonyPlayerRenderer extends LivingEntityRenderer<AbstractClientPlayer, PlayerModel<AbstractClientPlayer>> { private final PlayerModel<AbstractClientPlayer> earthModel; private final PlayerModel<AbstractClientPlayer> pegasusModel; private final PlayerModel<AbstractClientPlayer> unicornModel; public PonyPlayerRenderer(final EntityRendererProvider.Context context, final boolean slim) { super( context, slim ? new PonyModelSlim(context.bakeLayer(PonyModelSlim.LAYER_LOCATION)) : new PonyModel(context.bakeLayer(PonyModel.LAYER_LOCATION)), 0.5f ); System.out.println("creating new PonyPlayerRenderer"); this.earthModel = slim ? new PonyModelSlim(context.bakeLayer(PonyModelSlim.LAYER_LOCATION)) : new PonyModel(context.bakeLayer(PonyModel.LAYER_LOCATION)); this.pegasusModel = new PegasusModel(context.bakeLayer(PegasusModel.LAYER_LOCATION)); this.unicornModel = new UnicornModel(context.bakeLayer(UnicornModel.LAYER_LOCATION)); } @Override public void render(final AbstractClientPlayer player, final float entityYaw, final float partialTicks, final PoseStack poseStack, final MultiBufferSource buffer, final int packedLight) { final PonyRace race = player.getCapability(PONY_DATA) .map(data -> ofNullable(data.getRace()).orElse(PonyRace.EARTH)) .orElse(PonyRace.EARTH); this.model = switch (race) { case PEGASUS -> pegasusModel; case UNICORN -> unicornModel; case EARTH -> earthModel; }; super.render(player, entityYaw, partialTicks, poseStack, buffer, packedLight); } @Override public ResourceLocation getTextureLocation(final AbstractClientPlayer player) { final PonyRace race = player.getCapability(PONY_DATA) .map(data -> ofNullable(data.getRace()).orElse(PonyRace.EARTH)) .orElse(PonyRace.EARTH); return switch (race) { case EARTH -> fromNamespaceAndPath(MODID, "textures/entity/earth_pony.png"); case PEGASUS -> fromNamespaceAndPath(MODID, "textures/entity/pegasus.png"); case UNICORN -> fromNamespaceAndPath(MODID, "textures/entity/unicorn.png"); }; } } @Mod.EventBusSubscriber(modid = MODID, bus = MOD, value = CLIENT) public class ClientRenderers { // mod bus render registration config @SubscribeEvent public static void onRegisterLayerDefinitions(final EntityRenderersEvent.RegisterLayerDefinitions event) { event.registerLayerDefinition(PonyModel.LAYER_LOCATION, PonyModel::createBodyLayer); event.registerLayerDefinition(PonyModelSlim.LAYER_LOCATION, PonyModelSlim::createBodyLayer); event.registerLayerDefinition(PegasusModel.LAYER_LOCATION, PegasusModel::createBodyLayer); event.registerLayerDefinition(UnicornModel.LAYER_LOCATION, UnicornModel::createBodyLayer); event.registerLayerDefinition(InnerPonyArmorModel.LAYER_LOCATION, InnerPonyArmorModel::createBodyLayer); event.registerLayerDefinition(OuterPonyArmorModel.LAYER_LOCATION, OuterPonyArmorModel::createBodyLayer); } @SubscribeEvent public static void onRegisterRenderers(final EntityRenderersEvent.RegisterRenderers event) { event.registerEntityRenderer(EntityType.PLAYER, PonyPlayerWrapperRenderer::new); System.out.println("onRegisterRenderers end"); } } Method onRegisterRenderers() is called and I can see it being logged. But when I enter the world, my PonyWrapperRenderer render() method doesn't ever seem to be called. I also tried to put my renderer to EntityRenderDispatcher's playerRenderers via reflection: @Mod.EventBusSubscriber(modid = MODID, bus = MOD, value = CLIENT) public class ClientRenderers { @SubscribeEvent public static void onRegisterLayerDefinitions(final EntityRenderersEvent.RegisterLayerDefinitions event) { event.registerLayerDefinition(PonyModel.LAYER_LOCATION, PonyModel::createBodyLayer); event.registerLayerDefinition(PonyModelSlim.LAYER_LOCATION, PonyModelSlim::createBodyLayer); event.registerLayerDefinition(PegasusModel.LAYER_LOCATION, PegasusModel::createBodyLayer); event.registerLayerDefinition(UnicornModel.LAYER_LOCATION, UnicornModel::createBodyLayer); event.registerLayerDefinition(InnerPonyArmorModel.LAYER_LOCATION, InnerPonyArmorModel::createBodyLayer); event.registerLayerDefinition(OuterPonyArmorModel.LAYER_LOCATION, OuterPonyArmorModel::createBodyLayer); } @SubscribeEvent public static void onClientSetup(final FMLClientSetupEvent event) { event.enqueueWork(() -> { try { final EntityRenderDispatcher dispatcher = Minecraft.getInstance().getEntityRenderDispatcher(); final Field renderersField = getEntityRenderDispatcherField("playerRenderers"); final Field itemInHandRenderer = getEntityRenderDispatcherField("itemInHandRenderer"); @SuppressWarnings("unchecked") final Map<String, EntityRenderer<? extends Player>> playerRenderers = (Map<String, EntityRenderer<? extends Player>>)renderersField.get(dispatcher); final PonyPlayerWrapperRenderer renderer = new PonyPlayerWrapperRenderer( new EntityRendererProvider.Context( dispatcher, Minecraft.getInstance().getItemRenderer(), Minecraft.getInstance().getBlockRenderer(), (ItemInHandRenderer)itemInHandRenderer.get(dispatcher), Minecraft.getInstance().getResourceManager(), Minecraft.getInstance().getEntityModels(), Minecraft.getInstance().font ) ); playerRenderers.put("default", renderer); playerRenderers.put("slim", renderer); System.out.println("Player renderers replaced"); } catch (final Exception e) { throw new RuntimeException("Failed to replace player renderers", e); } }); } private static Field getEntityRenderDispatcherField(final String fieldName) throws NoSuchFieldException { final Field field = EntityRenderDispatcher.class.getDeclaredField(fieldName); field.setAccessible(true); return field; } } But I receive the error before Minecraft Client appears (RuntimeException: Failed to replace player renderers - from ClientRenderers onClientSetup() method - and its cause below): java.lang.IllegalArgumentException: No model for layer anotherlittlepony:earth_pony#main at net.minecraft.client.model.geom.EntityModelSet.bakeLayer(EntityModelSet.java:18) ~[forge-1.20.1-47.4.0_mapped_official_1.20.1-recomp.jar:?] {re:classloading,pl:runtimedistcleaner:A} at net.minecraft.client.renderer.entity.EntityRendererProvider$Context.bakeLayer(EntityRendererProvider.java:69) ~[forge-1.20.1-47.4.0_mapped_official_1.20.1-recomp.jar:?] {re:classloading,pl:runtimedistcleaner:A} at com.thuggeelya.anotherlittlepony.client.renderer.pony.PonyPlayerRenderer.<init>(PonyPlayerRenderer.java:32) ~[main/:?] {re:classloading} at com.thuggeelya.anotherlittlepony.client.renderer.pony.PonyPlayerWrapperRenderer.<init>(PonyPlayerWrapperRenderer.java:24) ~[main/:?] {re:classloading} at com.thuggeelya.anotherlittlepony.client.renderer.ClientRenderers.lambda$onClientSetup$0(ClientRenderers.java:79) ~[main/:?] {re:classloading} ... 33 more Problem appears when EntityRendererProvider context tries to bakeLayer with my model layer location: new PonyModel(context.bakeLayer(PonyModel.LAYER_LOCATION)); // PonyPlayerRenderer.java:32 public class PonyModel extends PlayerModel<AbstractClientPlayer> { // the model class itself public static final ModelLayerLocation LAYER_LOCATION = new ModelLayerLocation( ResourceLocation.fromNamespaceAndPath(MODID, "earth_pony"), "main" ); public PonyModel(final ModelPart root) { super(root, false); } public static LayerDefinition createBodyLayer() { // some CubeListBuilder stuff for model appearance } } Textures PNGs are placed at: resources/assets/[my mod id]/textures/entity.

      Using Mixins, gone bad with @At INVOKE value.

      By glektarssza · Posted

      Well, a bit more information about what you're trying to do would be helpful. e.g. why you're trying to use "INVOKE_ASSIGN" instead of "INVOKE". "INVOKE_ASSIGN" calls your code after the "target" is called and its value is stored, if applicable. "INVOKE" calls your code before the target is called. "target" expects a fully qualified name, as per the SpongePowered docs, if that name is going to be remapped (which it will be if your injecting into Minecraft itself and not another mod). For more information on fully qualified names versus canonical names, see the Java specifications. Here's an example of a working "@At" from my own code that targets the "getClosestsVulnerablePlayerToEntity" call inside a mob's logic: @At(value = "INVOKE_ASSIGN", target = "net.minecraft.world.World.getClosestVulnerablePlayerToEntity(Lnet/minecraft/entity/Entity;D)Lnet/minecraft/entity/player/EntityPlayer;") Hope this helps!

      Not Responding @ LOAD_REGISTRIES

      By hoshi · Posted

      Ran it one more time just to check, and there's no errors this time on the log??? Log : https://mclo.gs/LnuaAiu I tried allocating more memory to the modpack, around 8000MB and it's still the same; stopping at "LOAD_REGISTRIES". Are some of the mods clashing, maybe? I have no clue what to do LOL

      Not Responding @ LOAD_REGISTRIES

      By hoshi · Posted

      Tried removing some biome generation mods and test ran it again, but it's still the same; still not responding as soon as it gets to "LOAD_REGISTRIES". This time with more errors though. Log : https://mclo.gs/uygZzD8 Is there too little memory allocated to the modpack maybe? Can someone help please.    (T.T)💔
