[1.10/1.9.4] Block requires a block above it to exist


Recommended Posts

I'd like to make it so that the block I have created will only work if there is a block above it(it's meant to hang from the ceiling)


I've looked into classes like carpet and plants since the only work if a block is UNDER them but I can't figure out how to make it so that it will be destroyed/can't be placed unless there is a block above.


This is the class I have right now:


package bloopers.climbing.blocks;

import net.minecraft.block.Block;
import net.minecraft.block.material.MapColor;
import net.minecraft.block.material.Material;
import net.minecraft.block.state.IBlockState;
import net.minecraft.entity.EntityLivingBase;
import net.minecraft.util.EnumFacing;
import net.minecraft.util.math.AxisAlignedBB;
import net.minecraft.util.math.BlockPos;
import net.minecraft.world.IBlockAccess;

public class BlockRope extends Block {

    public static final AxisAlignedBB PILLAR_AABB = new AxisAlignedBB(0.375D, 0.0D, 0.375D, 0.625D, 1.5D, 0.625D);

public BlockRope(Material blockMaterialIn, MapColor blockMapColorIn) {
	super(Material.CLOTH, blockMapColorIn.BROWN);

    public AxisAlignedBB getBoundingBox(IBlockState state, IBlockAccess source, BlockPos pos)
	return PILLAR_AABB;


     * Used to determine ambient occlusion and culling when rebuilding chunks for render
    public boolean isOpaqueCube(IBlockState state)
        return false;

    public boolean isFullCube(IBlockState state)
        return false;

    public boolean isLadder(IBlockState state, IBlockAccess world, BlockPos pos, EntityLivingBase entity) { return true; }

How does that have anything to do with it?!

You get the BlockPos above another one using the


method. Then you use


to get the block at a position.

(probably looking super stupid)

I still don't really understand..

What is the up method, and how am I supposed to use it?

Do you understand Java?  At all?


The block is passed a World object and a BlockPos object.  Use them.

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable.  If you think this is the case, JUST REPORT ME.  Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.


Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.


DO NOT PM ME WITH PROBLEMS. No help will be given.
