I have a block of type BlockWire (which inherits from BlockHideable) that has a tile entity of type TileEntityWire (which in turn inherits from TileEntityHideable). The block mostly works like redstone, and should therefore be able to power redstone. My problem is that the wire doesn't update blocks properly. Redstone can only be turned on, while other wire blocks don't update at all. Also, if I click on the bottom on the block, it becomes visible (even though it shouldn't). I'm suspecting it is because BlockHideable sets the bounding box to AxisAligned(0, 0, 0, 0, 0, 0) instead of NULL_AABB, but if I return that the game crashes with a NullPointerException.

Didn't think it would matter, but here it is anyway.

Sorry for reviving this thread, but I really have no clue how to fix this. I've tried multiple variations of the code, but I'm just stuck.

Put a breakpoint where it crashes and check what is null, and why.

	@Override
	public AxisAlignedBB getSelectedBoundingBox(IBlockState state, World worldIn, BlockPos pos)
	{
		return state.getValue(HIDDEN) ? NULL_AABB : FULL_BLOCK_AABB;
	}
	
	@Override
	public AxisAlignedBB getBoundingBox(IBlockState state, IBlockAccess source, BlockPos pos)
	{
		return state.getValue(HIDDEN) ? NULL_AABB : FULL_BLOCK_AABB;
	}

If I have a new AxisAlignedBB with 0 as all of its parameters instead of NULL_AABB it works.

 

EDIT: I had initally thought this made a problem where the block became visible when right clicked, but later realised it couldn't be because of this since it also becomes visible when receiving a block update.

So the code on your Github is not up to date... How are we supposed to help you then?

getBoundingBox must not return null.

 

It is up to date. I mentioned in the post an experiment I made where I returned NULL_AABB in those methods, instead of a new AxisAlignedBB with 0 as all of its parameters, which resulted in a NullPointerException. I did this experiment because I thought having this empty object had an unintended side effect where the block became visible when right clicked. I realize now, however, that it can't be because of that since it also becomes visible when receiving any block update (from a lever, for example). I thought I could "fix" this by making the hitbox null, but again, the hitbox is most likely not the problem.

 

EDIT: Sorry for being unclear and editing my posts a lot, but I was pretty excited that someone would be able to help me (hopefully)
