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:

and my tileentity class:

package net.luis.cave.blocks.tileentity;

import java.util.Random;

import ;

public class LightningRodTileEntity extends TileEntity implements ITickableTileEntity {
	
	Random rng = this.getWorld().rand;
	
	public LightningRodTileEntity() {
		
		super(CaveTileEntityType.LIGHTNING_ROD);
		
	}
	
	

	@Override
	public void tick() {
		
		LightningBoltEntity lightning = new LightningBoltEntity(EntityType.LIGHTNING_BOLT, this.getWorld());
		lightning.setLocationAndAngles(this.getPos().getX(), this.getPos().getY(), this.getPos().getZ(), rng.nextFloat() * 360, 0);
		
		if (this.getWorld().isThundering()) {
			
			if (this.getWorld().getGameTime() % (350 - rng.nextInt(200)) == 0) {
				
				this.getWorld().addEntity(lightning);
				
			}
			
		}
		
	}

}

You never assign a value to LIGHTNING_ROD. When using registry events manually you need to use @ObjectHolder.

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

DeferredRegister is the other way.

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<>"

instead of a supplier, use the TileEntityType Builder

		LightningBoltEntity lightning = new LightningBoltEntity(EntityType.LIGHTNING_BOLT, this.getWorld());
		lightning.setLocationAndAngles(this.getPos().getX(), this.getPos().getY(), this.getPos().getZ(), rng.nextFloat() * 360, 0);
		
		if (this.getWorld().isThundering()) {
			
			if (this.getWorld().getGameTime() % (350 - rng.nextInt(200)) == 0) {
				
				this.getWorld().addEntity(lightning);
				
			}
			
		}
		
	

you first create a new LightningBoltEntity and after that you check if you need to, dont do that

i tried a bit but i don't understand how replace the Supplier with TileEntityType Builder

Have you tried looking whats inside the TileEntityType.Builder class? Then it will be very obvious which method you have to use to create you tile entity type
