Hi. I have a big question. I created a small block in the game, but I can't adjust the size of its hitbox in any way, and no errors are generated. I am attaching a screenshot and block code, I really hope for help.

package com.PermskyKit.TrueRopesMod.block;

import net.minecraft.block.Block;
import net.minecraft.block.BlockState;
import net.minecraft.util.math.BlockPos;
import net.minecraft.util.math.shapes.ISelectionContext;
import net.minecraft.util.math.shapes.VoxelShape;
import net.minecraft.world.IBlockReader;

public class RopeBlock extends Block{

	  public RopeBlock(Properties p_i48440_1_) {
		super(p_i48440_1_);
	}


    public VoxelShape func_220053_a(BlockState state, IBlockReader worldIn, BlockPos pos, ISelectionContext context) {
		    VoxelShape shape = Block.box(6, 0, 6, 10, 16, 10);
			return shape;
	 }
}

use @Override when overwrite methods

Where exactly should I write this?

Unfortunately it didn't help. Now my code looks like this, but the problem persists.

Look at e.g. FlowerPotBlock.

Where can i find this example?

in your IDE, in Eclipse you can search for the class when using CTRL + SHIFT + H,
im not familiar with the Intellij Shortcuts

Thanks a lot, I was not aware of this Eclipse feature. But even this method did not help, I am tormented by the question, maybe there should be some additional files besides "BlockInit", or the path to this "RopeBlock" file should be different.

I've already tried many variations of the code and .. Maybe I just don't know something else about Eclipse or the file structure.

With IntelliJ you double-press Shift to open the search-everywhere box.

I haven't used Eclipse in years, but you should find Minecraft's code (and assets) in your project's external libraries. You're looking for something along the lines of: https://imgur.com/jC0eGDK (this is from IntelliJ, mind you).

However, here's an example from 1.17 code, I believe it was still applicable in 1.16:

private static final VoxelShape PART_1  = Block.box(0.0, 0.0, 0.0, 16.0, 16.0, 16.0); // 16.0 is the full size of one block (in pixels)

@Override
public VoxelShape getShape(BlockState state, BlockGetter block, BlockPos pos, CollisionContext context)
{
    return PART_1;
}

// If you want multiple hitboxes, combine them like:
private static final VoxelShape AABB = Shapes.or(PART_1, PART_2); // You can add more parts here if necessary
// Then simply return this from getShape() instead of the individual part.

 

Looking at your code, I believe the reason it's not working is that you're creating the VoxelShape locally in the function. Once the function returns, that object goes out of scope and is destroyed. You want to move the declaration into the class itself. You can also make it static.

BlockGetter and CollisionContext do not work in version 1.16.5. Do you know how they were designated in this version?

All you need to do is to move the 

VoxelShape shape = Block.box(6, 0, 6, 10, 16, 10);

declaration out of the function, into the class, and preferably mark it as static. That should fix your issue.

Yes, I did it and was able to change the code, now it looks like this:

package com.PermskyKit.TrueRopesMod.blocks;

import net.minecraft.block.Block;
import net.minecraft.block.BlockState;
import net.minecraft.util.math.BlockPos;
import net.minecraft.util.math.shapes.ISelectionContext;
import net.minecraft.util.math.shapes.VoxelShape;
import net.minecraft.world.IBlockReader;

public class RopeBlock extends Block{

	  public RopeBlock(Properties properties) {
		super(properties);
	}
	  private static final VoxelShape PART_1  = Block.box(6.0, 0.0, 6.0, 10.0, 16.0, 10.0);

	  @Override
	  public VoxelShape getShape(BlockState state, IBlockReader block, BlockPos pos, ISelectionContext context)
	  {
	      return PART_1;
	  }
}

But alas, the usual full block hitbox remains in the game...

You've renamed

func_220053_a

to

getShape

, was this intentional?

Yes, because with func_220053_a Eclipse gives an error and suggests removing @Override.

Show where you register your block.

I'm sorry, for some reason I overlooked this question..

Class path:

TrueRopesMod/src/main/java/core.init/BlockInit

Code:

package core.init;

import com.PermskyKit.TrueRopesMod.TrueRopesMod;

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.AbstractBlock;
import net.minecraftforge.fml.RegistryObject;
import net.minecraftforge.registries.DeferredRegister;
import net.minecraftforge.registries.ForgeRegistries;

public class BlockInit {
	public static final DeferredRegister<Block> BLOCKS = DeferredRegister.create(ForgeRegistries.BLOCKS,
			TrueRopesMod.MOD_ID);

	public static final RegistryObject<Block> ROPE_BLOCK = BLOCKS.register("rope_block",
			() -> new Block(AbstractBlock.Properties.of(Material.GRASS, MaterialColor.TERRACOTTA_BROWN)
					.strength((float) 0.4)
					.sound(SoundType.CROP)));
}

What? What? What?

Block != RopeBlock.

Should it be a piece of code or a separate class? I don't know, since I'm just starting to learn Java and was writing this code from a tutorial.

🤦

Basic Java is a necessary prerequisite for modding.

Ahem, I'm sorry, I did a bit reworking of the mod structure, here's how the block is registered:

package com.PermskyKit.TrueRopesMod.block;

import com.PermskyKit.TrueRopesMod.TrueRopesMod;
import com.PermskyKit.TrueRopesMod.item.ModItemGroup;
import com.PermskyKit.TrueRopesMod.item.ModItems;

import net.minecraft.block.material.Material;
import net.minecraft.item.BlockItem;
import net.minecraft.item.Item;
import net.minecraftforge.common.ToolType;
import net.minecraftforge.eventbus.api.IEventBus;
import net.minecraftforge.fml.RegistryObject;
import net.minecraftforge.registries.DeferredRegister;
import net.minecraftforge.registries.ForgeRegistries;

public class ModBlocks {
	
    public static final DeferredRegister<Block> BLOCKS
    = DeferredRegister.create(ForgeRegistries.BLOCKS, TrueRopesMod.MOD_ID);
    
    
    
    public static final RegistryObject<Block> ROPE_BLOCK = registerBlock("rope_block",
            () -> new Block(AbstractBlock.Properties.of(Material.GRASS).harvestLevel(2).harvestTool(ToolType.PICKAXE)));
    
    
    
    private static <T extends Block>RegistryObject<T> registerBlock(String name, Supplier<T> block) {
        RegistryObject<T> toReturn = BLOCKS.register(name, block);
        registerBlockItem(name, toReturn);
        return toReturn;
    }
    
    private static <T extends Block> void registerBlockItem(String name, RegistryObject<T> block) {
        ModItems.ITEMS.register(name, () -> new BlockItem(block.get(),
                new Item.Properties().tab(ModItemGroup.TRUEROPESMOD)));
    }

	public static void register(IEventBus eventBus) {
        BLOCKS.register(eventBus);
    }

}
