[1.16.4] RenderRegistry#registerEntityRenderingHandler not working


Recommended Posts

Hello, I tried making an entity last night. I spent around 2 hours trying to figure out why I was getting an incompatible types error. And I couldn't figure it out.

I tried copying some code snippets off the forums that I found, but even that didn't work, and I'm left here confused.


I want to mention I read a fair bit of the docs (I skipped the parts that I don't need yet, like tile entities and what not). I also started learning forge yesterday, so please bare with me. Thanks in advance.

Oh my bad, I thought I did. I get a syntax error here. From what I've seen this is the right way to do it. So Im not sure what Im doing wrong.


    public static void registerRender(){
        RenderingRegistry.registerEntityRenderingHandler(COBBLESTONE_TURTLE.get(), CobblestoneTurtleRenderer::new);

I do know Java to a certain extent. I wouldn't call my self an expert but Im not a beginner. I realize it doesn't accept the variable Im assigning it. I just don't know why. Im pretty certain I have written everything correctly, especially since I've confirmed this by looking at other people's examples. I tried changing some stuff up to match the required variable but It still wouldn't work. Also if the solution is an easy one that Im missing, I apologize. I have a habit of missing small details sometimes

You know what. Ima just figure it out myself, you seem to not wanna help me anyways, instead telling me to do it myself. Thanks for the help.

the constructor of your Renderer contains two elemetnts a EntityRendererManager and a float

the IRenderFactory needs only the EntityRendererManager

In addition, the Factory cannot do anything with the float and gives you the error

that's exactly what @diesieben07 meant by

Look at the two and understand how method references work.

    • Hello. I'm using IntelliJ IDEA and making a mod for Forge 1.20.1 and I'm trying to make a GUI. I found that the Minecraft-related codes are all obfuscated and when setting up the workspace, Gradle did not execute Deobfuscation tasks like createMcpToSrg. Is this normal or a bug? Can anyone help me with this?
    • Hello! I'm trying to get a list of all entries registered in the infusion upgrade registry. Code can be found in github: https://github.com/ChamoisEST/MiningMadness/tree/1.20.1 Registry in common/registries/MMRegistries.java Event that calls the registry is in MiningMadness.java List of registered entries should be called in common/capabilities/infusion/InfusionCapabilityImplementation.java:getActiveInfusions() in the for loop. Is there any way to accomplish that? Thanks in advance!  
    • So, I am trying to create and add tags to my custom damage type, but looks like I made something wrong, since it crashing with error that "cannot register" damage type. Im trying to register it, and in datagen add tags, but it everytime crashing due to not register "grimtales:entropy". Full code there - https://github.com/undertakerJ/Grim-Tales-Forge ModDamageTypes class public class ModDamageTypes { public static final DeferredRegister<DamageType> DAMAGE_TYPES = DeferredRegister.create(Registries.DAMAGE_TYPE, GrimTales.MOD_ID); public static final ResourceKey<DamageType> ENTROPY_KEY = ResourceKey.create(Registries.DAMAGE_TYPE, new ResourceLocation(GrimTales.MOD_ID, "entropy")); public static final RegistryObject<DamageType> ENTROPY = DAMAGE_TYPES.register( "entropy", () -> new DamageType("entropy_effect", DamageScaling.ALWAYS, 1f, DamageEffects.HURT)); // // public static final DamageSource ENTROPY_SOURCE = new DamageSource(Holder.direct(ENTROPY.get())); public static void register(IEventBus eventBus) { DAMAGE_TYPES.register(eventBus); } } Datagen for damageTags public class ModDamageTagsProvider extends DamageTypeTagsProvider { public ModDamageTagsProvider( PackOutput p_270719_, CompletableFuture<HolderLookup.Provider> p_270256_, @Nullable ExistingFileHelper existingFileHelper) { super(p_270719_, p_270256_, GrimTales.MOD_ID, existingFileHelper); } @Override protected void addTags(HolderLookup.Provider pProvider) { this.tag(DamageTypeTags.BYPASSES_INVULNERABILITY).add(ModDamageTypes.ENTROPY_KEY); } } Datagen class it self   @Mod.EventBusSubscriber(modid = GrimTales.MOD_ID, bus = Mod.EventBusSubscriber.Bus.MOD) public class DataGenerators { @SubscribeEvent public static void gatherData(GatherDataEvent event){ DataGenerator generator = event.getGenerator(); PackOutput packOutput = generator.getPackOutput(); ExistingFileHelper helper = event.getExistingFileHelper(); CompletableFuture<HolderLookup.Provider> lookupProvider = event.getLookupProvider(); generator.addProvider(event.includeServer(), new ModDamageTagsProvider(packOutput, lookupProvider, helper)); } } And register class in main class public GrimTales() { IEventBus modEventBus = FMLJavaModLoadingContext.get().getModEventBus(); ModDamageTypes.register(modEventBus); modEventBus.addListener(this::commonSetup); MinecraftForge.EVENT_BUS.register(this); modEventBus.addListener(this::addCreative); }

    • Hi. I'm trying to play RLCraft with Optifine but my game keeps crashing on startup with Exit Code 1. The modpack was working fine yesterday, not sure what changed to make it not wanna work anymore. I was hoping someone here could help me figure out what's going wrong. If I remove Optifine, nothing changes, I still get the same errors. Thanks in advance.
