World.func_152378_a(UUID) is supposed to return an EntityPlayer, but when I try to call it with a saved player ID (at world load, using NBT tags), it returns null. Does anyone know what I'm doing wrong?

1) Check that player is already logged in

2) Check that you're doing it in correct world (each dimension has different worlds)

I'm not sure I can, since the loading occurs in the entity class. Is there a way for me to check when the player logs in, inside of that class?

 

Just did the dimension saving thing; it made no difference, still returns null.

Oh, right! Now I get it. Thanks for clearing that up.

 

I pretty much copied the way EntityAIFollowOwner does it, except I don't use data watchers because I am not familiar with them.

 

A UUID is used in the Entity, because it is passed in from the egg it hatches from.

 

An EntityPlayer is used in the AI, because otherwise I'd be calling worldObj.func_152378_a(UUID) all the time to get one for the information required to move towards it.

Has anyone got any idea why this might be happening?

 

Should I try switching the Entity to inherit from EntityTameable, and use the vanilla EntityAIFollowOwner?

If I did, how would I set the owner the moment the egg hatched, rather than when it was fed a certain item?

I have a question about the players UUID. How are they actually saved, Ive been looking at the Yggdrasil class with Ernio and we both got stumped by how/where the players uuid is actually being saved. I want to create a dynamic link between an entity and the player and so far I havent had any luck with this.

How:

uuid.toString returns string form uuid. UUID.fromString returns uuid from string. I hope you know how to save string, right?

 

Where:

EntityTameable.getOwner returns owner from watchable string (representing uuid) with id 17, that is saved and loaded like all data watchers....

    • 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.

    • 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!
    • 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
    • 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)💔
    • This is sad. Over 3300 people have checked the thread and no one is able to help or give any ideas :(.
