So I'm trying to include a config-file in my 1.13.2 mod. And I've added a boolean in my config to regulate if an ore should be generated or not. Now I've got a problem with that because i get an java.lang.NullPointerException: Cannot get config value without assigned Config object present when testing on those boolean values. The error come up on the OreGeneration.java in the if-statements in setupOreGen() Does anybody have an idea why that happens or could someone have a look in my code? Thanks in advantage:) Here's the link to my GitHub: https://github.com/jonas69/Versio

Okay i didn't thought of that, but now it works! Thank you very much, esp. that your responses were so quick:)

Yes exactly, thats the strange thing. I know that there's a comment in this line, but if i run the client (with the code just like on github), i get this log with those error-messages. I just tried it again, chose the client in run-config, then the game startet and gave me this latest.log with exactly the line 29 even though there's java-doc

My bad, heres the new log: latest.log

Oh right, it should be now:)

Okay, here's the link: https://github.com/jonas69/Versio And thanks for your effort:)

Thanks for the quick reply! I only have two blocks and these are the classes: Thats the first one: package com.versio.block; import com.versio.init.ModItems; import net.minecraft.block.Block; import net.minecraft.block.SoundType; import net.minecraft.block.material.Material; import net.minecraft.block.material.MaterialColor; import net.minecraft.block.state.IBlockState; import net.minecraft.item.ItemStack; import net.minecraft.util.NonNullList; import net.minecraft.util.math.BlockPos; import net.minecraft.world.World; import net.minecraftforge.common.ToolType; public class BlockManganOre extends Block { public BlockManganOre() { super(Properties.create(Material.ROCK, MaterialColor.RED).hardnessAndResistance(3.0F, 2.0F) .sound(SoundType.STONE)); this.setRegistryName("mangan_ore"); } @Override public int getHarvestLevel(IBlockState state) { return 2; } @Override public ToolType getHarvestTool(IBlockState state) { return ToolType.PICKAXE; } @Override public void getDrops(IBlockState state, NonNullList<ItemStack> drops, World world, BlockPos pos, int fortune) { drops.add(new ItemStack(ModItems.MANGAN, 1 + fortune)); } } And thats the second: package com.versio.block; import com.versio.init.ModItems; import com.versio.tileentity.TileEntityJar; import net.minecraft.block.Block; import net.minecraft.block.material.Material; import net.minecraft.block.state.IBlockState; import net.minecraft.entity.item.EntityItem; import net.minecraft.entity.player.EntityPlayer; import net.minecraft.item.ItemStack; import net.minecraft.tileentity.TileEntity; import net.minecraft.util.BlockRenderLayer; import net.minecraft.util.EnumFacing; import net.minecraft.util.EnumHand; import net.minecraft.util.math.BlockPos; import net.minecraft.util.math.shapes.VoxelShape; import net.minecraft.world.IBlockReader; import net.minecraft.world.World; public class BlockJar extends Block { public BlockJar() { super(Properties.create(Material.GLASS).hardnessAndResistance(.6F)); this.setRegistryName("jar"); } @Override public boolean onBlockActivated(IBlockState state, World worldIn, BlockPos pos, EntityPlayer player, EnumHand hand, EnumFacing side, float hitX, float hitY, float hitZ) { TileEntityJar jar = (TileEntityJar) worldIn.getTileEntity(pos); if (jar.amount() < 64 && !player.getHeldItem(hand).isEmpty() && player.getHeldItem(hand).getItem().equals(ModItems.MANGAN) && !player.isSneaking()) { player.getHeldItem(hand).shrink(1); jar.addCrystals(); return true; } else if (player.isSneaking() && jar.amount() > 0) { player.addItemStackToInventory(new ItemStack(ModItems.MANGAN)); jar.removeCrystals(); return true; } return false; } @Override public void harvestBlock(World worldIn, EntityPlayer player, BlockPos pos, IBlockState state, TileEntity te, ItemStack stack) { TileEntityJar jar = (TileEntityJar) te; while (jar.amount() > 0) { if (!worldIn.isRemote) { worldIn.spawnEntity(new EntityItem(worldIn, pos.getX(), pos.getY(), pos.getZ(), new ItemStack(ModItems.MANGAN))); jar.removeCrystals(); } } super.harvestBlock(worldIn, player, pos, state, te, stack); } @Override public boolean isBlockNormalCube(IBlockState state) { return false; } @Override public boolean isFullCube(IBlockState state) { return false; } @Override public BlockRenderLayer getRenderLayer() { return BlockRenderLayer.CUTOUT; } @Override public VoxelShape getShape(IBlockState state, IBlockReader worldIn, BlockPos pos) { return Block.makeCuboidShape(3.0D, 0.0D, 3.0D, 13.0D, 13.0D, 13.0D); } @Override public boolean hasTileEntity(IBlockState state) { return true; } @Override public TileEntity createTileEntity(IBlockState state, IBlockReader world) { return new TileEntityJar(); } }

Hello, i'm trying myself in coding a Mod for 1.13.2 and while creating and testing my first ore, i ran into this error: "Exception caught during firing event: Can't use a null-name for the registry, object Block{minecraft:air}." I use the latest forge mdk. I did not touch the minecraft:air, i just added a new ore. I also set its registry name in the ore-class-constructor like so: this.setRegistryName("mangan_ore"); I will add the log and this is my ModBlocks file, where i register all my blocks/itemblocks: package com.versio.init; import static com.versio.util.InjectionUtil.Null; import com.google.common.base.Preconditions; import com.versio.Versio; import com.versio.block.BlockJar; import com.versio.block.BlockManganOre; import net.minecraft.block.Block; import net.minecraft.item.EnumRarity; import net.minecraft.item.Item; import net.minecraft.item.ItemBlock; import net.minecraft.util.ResourceLocation; import net.minecraftforge.event.RegistryEvent; import net.minecraftforge.eventbus.api.SubscribeEvent; import net.minecraftforge.fml.common.Mod; import net.minecraftforge.registries.ObjectHolder; @ObjectHolder(Versio.MODID) public class ModBlocks { public static final BlockManganOre MANGAN_ORE = Null(); public static final BlockJar JAR = Null(); @Mod.EventBusSubscriber(modid = Versio.MODID, bus = Mod.EventBusSubscriber.Bus.MOD) public static class Register { @SubscribeEvent public static void registerBlock(final RegistryEvent.Register<Block> event) { final Block[] blocks = {new BlockManganOre(), new BlockJar()}; event.getRegistry().registerAll(blocks); } @SubscribeEvent public static void registerItemBlocks(final RegistryEvent.Register<Item> event) { final ItemBlock[] items = { new ItemBlock(MANGAN_ORE, new Item.Properties().maxStackSize(64).rarity(EnumRarity.UNCOMMON) .group(Versio.MODTAB)), new ItemBlock(JAR, new Item.Properties().maxStackSize(16) .rarity(EnumRarity.UNCOMMON).group(Versio.MODTAB))}; for (final ItemBlock item : items) { final Block block = item.getBlock(); final ResourceLocation registryName = Preconditions.checkNotNull( block.getRegistryName(), "Block %s has a null registry name", block); event.getRegistry().register(item.setRegistryName(registryName)); } } } } Does someone know, what the cause of that error is? latest.log
