I am trying to figure out how to make a block where some mobs can pass through it where others cannot.

 

Unless someone knows of a better way, I am guessing I have to handle this somehow with this method:

public void onEntityCollidedWithBlock(World worldIn, BlockPos pos, IBlockState state, Entity entity)
{
	if(entity instanceof EntityMob)
	{
		// do something here
	}
}

 

I don't have a very good understanding of EnumFacing if that has to be used and would have to need some explanation on how to use it here.

 

I would also like to make this block so all mobs (not just a select few) cannot see through it. It seems if a block is passable in any way, a mob can see through it. Can I prevent them from seeing through a passable block?

Thanks! So with your suggestion I came up with this and it seems to work as desired:

@Override //Depreciated
public void addCollisionBoxToList(IBlockState state, World worldIn, BlockPos pos, AxisAlignedBB entityBox, List<AxisAlignedBB> collidingBoxes, @Nullable Entity entity, boolean p_185477_7_)
{
	if(!(entity instanceof TamablePokemon) && !(entity instanceof EntityPlayer))
	{
		AxisAlignedBB axisalignedbb = state.getBoundingBox(worldIn, pos).offset(pos);

		if (entityBox.intersectsWith(axisalignedbb))
		{
			collidingBoxes.add(axisalignedbb);
		}
	}
}

 

Should I be at all concerned that this Method is marked as Depreciated? Like, it getting removed in a future update?

Basically not really. The method is marked deprecated which means do not call this method. You should still override it to get the desired behavior.

Thanks, I was hoping that was the case rather than it was a warning assuring it was gonna be removed. I'm trying to think ahead for scalability into future updates.

The functionailiy will continue to exist as Minecraft evolves, but it is possible that the method does get removed and placed somewhere else. It will depend on how Mojang continues to work with the IBlockState format.
