did you added the registration to your mod class constructor like this: yourClass.RECIPE_SERIALIZERS.register(FMLJavaModLoadingContext.get().getModEventBus());

This is currently an error in my IDE but i dont know why

i remove the complete event and lava will create source - i export the mod and check it outside of the ide again

that's how it should work true: can creat source false can't creat source when i set the gamrule to true/false lava always creat source but why

I've added a few new rules to minecraft and now I'm creating the functions. But some of my functions not work / they don't work as they should. Enable lava fluid source - if the gamerule is true lava source are enabled but it dont work but why this is the code i use (BlockEvent.CreateFluidSourceEvent) https://github.com/Luis-st/Forge-1.16.5-36.0.1-mdk/blob/main/forge-1.16.5-36.0.1-mdk/src/main/java/net/luis/cave/events/world/block/OnCreateFluidSourceEvent.java error: no matter if true or false lava can always creat source

you have to extends BlockNamedItem you have to creat two stem blocks one extends StemBlock the other AttachedStemBlock look how vanilla does it

it works thank you

thanks but i have already fixed this problem i tried a bit but i don't understand how replace the Supplier with TileEntityType Builder

you want to look through the block and the should be semi-translucent - semi-transparent to the light that comes through the block? than try to set getOpacity (15 no light through the block 0 all light through the block) - if you mean semi-transparent that you can't look through the block like vanilla colored glass than set the alpah of your texture if not i dont understand how semi-transparent is for you ps: i think forge can only set one rendertype

I kown but DefferredRegister will not work/I got an error which i don't understand: public static final DeferredRegister<TileEntityType<?>> TILE_ENTITIES = DeferredRegister.create(ForgeRegistries.TILE_ENTITIES, Cave.Mod_Id); public static final RegistryObject<TileEntityType<LightningRodTileEntity>> LIGHTNING_ROD = TILE_ENTITIES.register("lightminig_rod_tileentity", () -> new TileEntityType<>(LightningRodTileEntity::new, CaveBlocks.LIGHTNING_ROD.get(), null)); 1. what should i add at "null" 2. when i add the Block which the TileEntity is vaild i got this error/ my ide say there is an error: "Cannot infer type arguments for TileEntityType<>"

what do you mean with "manually" is there another way to register TileEntitys

i think you have to add notSolid to your Block Properties if you mean "xRay" you can look through the block into the world and what du you mean with

i just want to add to my custom block (lightning rod) a tile entity but i got an error and i know there is an error in registration but i dont know where code: (code is frome the documentation package net.luis.cave.init; import ; @Mod.EventBusSubscriber(modid = Cave.Mod_Id, bus = Mod.EventBusSubscriber.Bus.MOD) public class CaveTileEntityType { public static final TileEntityType<LightningRodTileEntity> LIGHTNING_ROD = null; @SubscribeEvent public static void registerTE(RegistryEvent.Register<TileEntityType<?>> event) { TileEntityType<?> type = TileEntityType.Builder .create(LightningRodTileEntity::new, CaveBlocks.LIGHTNING_ROD.get()) .build(null); type.setRegistryName(Cave.Mod_Id, "lightminig_rod_tileentity"); event.getRegistry().register(type); } } and the error log: net.minecraft.crash.ReportedException: Ticking block entity at net.minecraft.server.MinecraftServer.updateTimeLightAndEntities(MinecraftServer.java:888) ~[forge:?] {re:classloading,pl:accesstransformer:B} at net.minecraft.server.MinecraftServer.tick(MinecraftServer.java:820) ~[forge:?] {re:classloading,pl:accesstransformer:B} at net.minecraft.server.integrated.IntegratedServer.tick(IntegratedServer.java:84) ~[forge:?] {re:classloading,pl:runtimedistcleaner:A} at net.minecraft.server.MinecraftServer.func_240802_v_(MinecraftServer.java:663) ~[forge:?] {re:classloading,pl:accesstransformer:B} at net.minecraft.server.MinecraftServer.lambda$startServer$0(MinecraftServer.java:233) ~[forge:?] {re:classloading,pl:accesstransformer:B} at java.lang.Thread.run(Thread.java:832) [?:?] {} Caused by: java.lang.NullPointerException: Cannot invoke "net.minecraft.tileentity.TileEntityType.isValidBlock(net.minecraft.block.Block)" because the return value of "net.minecraft.tileentity.TileEntity.getType()" is null at net.minecraft.world.World.tickBlockEntities(World.java:537) ~[forge:?] {re:classloading,pl:accesstransformer:B} at net.minecraft.world.server.ServerWorld.tick(ServerWorld.java:374) ~[forge:?] {re:classloading} at net.minecraft.server.MinecraftServer.updateTimeLightAndEntities(MinecraftServer.java:884) ~[forge:?] {re:classloading,pl:accesstransformer:B} ... 5 more [13:52:48] [Server thread/ERROR] [minecraft/Chunk]: A TileEntity type net.luis.cave.blocks.tileentity.LightningRodTileEntity has thrown an exception trying to write state.

i just test it with setPositionAndUpdate and it works

i understand when i check if the lightning is add i canceled the event and add a new lightning question: when i change the pos of the lightning the event will not called again?

i just creat a block which works like the minecraft lightning rod. i use to detcet if a lightning is strik the entity join world event but i got an error (null but i dont know where and why null): code: https://github.com/Luis-st/Forge-1.16.5-36.0.1-mdk/blob/main/forge-1.16.5-36.0.1-mdk/src/main/java/net/luis/cave/events/entity/OnEntityJoinWorldEvent.java log: https://github.com/Luis-st/Forge-1.16.5-36.0.1-mdk/blob/main/forge-1.16.5-36.0.1-mdk/src/main/java/net/luis/cave/events/entity/player/Error Log

i currently fixed the error so it works thanks

than this while (enchantmentIterator.hasNext()) { Enchantment enchantment = (Enchantment) enchantmentIterator; if (!enchantment.isCompatibleWith(enchantmentIterator.next())) { enchantmentIterator.remove(); } }

while (enchantmentIterator.hasNext()) { Enchantment enchantment = (Enchantment) enchantmentIterator.next(); if (!enchantment.isCompatibleWith((Enchantment) enchantmentIterator)) { enchantmentIterator.remove(); } } so is this correct? and how to remove now the level of the enchantment?

but how to do that

so i have to convert the list to an iterator?

i just have a custom overlay which i render but i want to render the overlay only if the player is in 1st person

i tested the minecraft code a bit and vanilla trades work fine. there are no enchantment twice? so i creat my custom addRandomEnchantment and it works fine but: when i remove incompatible enchantments i got an error: private static Map<Enchantment, Integer> removeIncompatible(Map<Enchantment, Integer> enchantments) { Map<Enchantment, Integer> returnMap = new HashMap<Enchantment, Integer>(); List<Enchantment> enchantmentList = enchantments.keySet().stream().collect(Collectors.toList()); List<Integer> levelList = enchantments.values().stream().collect(Collectors.toList()); for (int i = 0; i < enchantmentList.size(); i++) { for (Enchantment enchantment : enchantmentList) { if (!enchantment.isCompatibleWith(enchantmentList.get(i))) { enchantmentList.remove(i); levelList.remove(i); } } } for (int i = 0; i < enchantmentList.size(); i++) { returnMap.put(enchantmentList.get(i), levelList.get(i)); } return returnMap; } and the error: java.util.ConcurrentModificationException: null at java.util.ArrayList$Itr.checkForComodification(ArrayList.java:1013) ~[?:?] {} at java.util.ArrayList$Itr.next(ArrayList.java:967) ~[?:?] {} at net.luis.cave.lib.EnchantmentManager.removeIncompatible(EnchantmentManager.java:144) ~[main/:?] {re:classloading} at net.luis.cave.lib.EnchantmentManager.addRandomEnchantment(EnchantmentManager.java:116) ~[main/:?] {re:classloading} at net.luis.cave.events.entity.player.interact.OnRightClickBlockEvent.PlayerInteract(OnRightClickBlockEvent.java:34) ~[main/:?] {re:classloading} at net.minecraftforge.eventbus.ASMEventHandler_24_OnRightClickBlockEvent_PlayerInteract_RightClickBlock.invoke(.dynamic) ~[?:?] {} at net.minecraftforge.eventbus.ASMEventHandler.invoke(ASMEventHandler.java:85) ~[eventbus-4.0.0.jar:?] {} at net.minecraftforge.eventbus.EventBus.post(EventBus.java:302) ~[eventbus-4.0.0.jar:?] {} at net.minecraftforge.eventbus.EventBus.post(EventBus.java:283) ~[eventbus-4.0.0.jar:?] {} at net.minecraftforge.common.ForgeHooks.onRightClickBlock(ForgeHooks.java:803) ~[forge-1.16.5-36.0.1_mapped_snapshot_20201028-1.16.3-recomp.jar:?] {re:classloading} at net.minecraft.client.multiplayer.PlayerController.func_217292_a(PlayerController.java:286) ~[forge-1.16.5-36.0.1_mapped_snapshot_20201028-1.16.3-recomp.jar:?] {re:classloading,pl:runtimedistcleaner:A} at net.minecraft.client.Minecraft.rightClickMouse(Minecraft.java:1407) ~[forge-1.16.5-36.0.1_mapped_snapshot_20201028-1.16.3-recomp.jar:?] {re:classloading,pl:accesstransformer:B,pl:runtimedistcleaner:A} at net.minecraft.client.Minecraft.processKeyBinds(Minecraft.java:1692) ~[forge-1.16.5-36.0.1_mapped_snapshot_20201028-1.16.3-recomp.jar:?] {re:classloading,pl:accesstransformer:B,pl:runtimedistcleaner:A} at net.minecraft.client.Minecraft.runTick(Minecraft.java:1507) ~[forge-1.16.5-36.0.1_mapped_snapshot_20201028-1.16.3-recomp.jar:?] {re:classloading,pl:accesstransformer:B,pl:runtimedistcleaner:A} at net.minecraft.client.Minecraft.runGameLoop(Minecraft.java:979) ~[forge-1.16.5-36.0.1_mapped_snapshot_20201028-1.16.3-recomp.jar:?] {re:classloading,pl:accesstransformer:B,pl:runtimedistcleaner:A} at net.minecraft.client.Minecraft.run(Minecraft.java:612) ~[forge-1.16.5-36.0.1_mapped_snapshot_20201028-1.16.3-recomp.jar:?] {re:classloading,pl:accesstransformer:B,pl:runtimedistcleaner:A} at net.minecraft.client.main.Main.main(Main.java:184) ~[forge-1.16.5-36.0.1_mapped_snapshot_20201028-1.16.3-recomp.jar:?] {re:classloading,pl:runtimedistcleaner:A} at jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) ~[?:?] {} at jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:64) ~[?:?] {} at jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) ~[?:?] {} at java.lang.reflect.Method.invoke(Method.java:564) ~[?:?] {} at net.minecraftforge.userdev.FMLUserdevClientLaunchProvider.lambda$launchService$0(FMLUserdevClientLaunchProvider.java:52) ~[forge-1.16.5-36.0.1_mapped_snapshot_20201028-1.16.3-recomp.jar:?] {} at cpw.mods.modlauncher.LaunchServiceHandlerDecorator.launch(LaunchServiceHandlerDecorator.java:37) [modlauncher-8.0.9.jar:?] {} at cpw.mods.modlauncher.LaunchServiceHandler.launch(LaunchServiceHandler.java:54) [modlauncher-8.0.9.jar:?] {} at cpw.mods.modlauncher.LaunchServiceHandler.launch(LaunchServiceHandler.java:72) [modlauncher-8.0.9.jar:?] {} at cpw.mods.modlauncher.Launcher.run(Launcher.java:82) [modlauncher-8.0.9.jar:?] {} at cpw.mods.modlauncher.Launcher.main(Launcher.java:66) [modlauncher-8.0.9.jar:?] {} at net.minecraftforge.userdev.LaunchTesting.main(LaunchTesting.java:105) [forge-1.16.5-36.0.1_mapped_snapshot_20201028-1.16.3-recomp.jar:?] {}
