Minecraft – Why does the item elevator only worked when oriented north/south

minecraft-java-editionminecraft-redstone

I made a slight modification to the item elevator outlined in this video – namely, I shifted the redstone ladder after the first block forward one block to minimize the horizontal footprint.

When the redstone ladder is oriented north/south, it works exactly like the one in the video – it's completely silent and will move all items placed in the intake to the top, with nothing remaining. However, when the ladder is oriented east/west, each dropper clicks once with the first item, and an item is left behind in every odd dropper, starting at the third dropper and continuing for the rest of the elevator.

I tested all four orientation of the elevator but only included two in these screenshots. I also tested different signal pulsers and different input/output directions, with the same result. The elevators are identical except for orientation – the one with green wool on top works, the one with red doesn't. The glazed terracotta is pointing north.

As you might expect, this is due to a bug. Sadly there is a variety of bugs with "directional" redstone and adding blocks to the mix that are affected by QC does not make it any less complicated. So I don't actually know which bug is to blame here and how exactly a workaround would work. You'll just have to experiment and see what works and what doesn't. In the meantime, you can vote for or read some related bug reports:

Some behaviours are also "locational", meaning that they can break if you just move the entire contraption one block to the side. And I've also heard about bugs that only occur in the positive or negative X/Z coordinates. But those kinds of bugs luckily got pretty rare recently.

Minecraft – How to power a row of droppers efficiently from side or bottom

The most resource efficient way I can come up with to power a horizontal line of droppers is this

enter image description here

with the redstone line on the left being connected to a clock. This works because the repeaters strongly power the dropper they are pointing into causing the droppers to the left and right to be indirectly powered.

The vertical line of droppers is powered as described in this Youtube video, with a comparator being used to send a (inverted by a redstone torch) signal to a vertical stack of redstone torches powering repeaters pointing into every 2nd vertical dropper.

With regards to the specific situation you are in the most resource efficient way to get the mobs from the exit of the spawner to the 'home' area would be to bring them up high enough using a mob elevator (a 1x1 tube filled with alternating water blocks and signs will cause the mobs to swim themselves up to the top) to a point where they can be dropped down the required number of blocks.

The only pitfall with this type of system is ensuring that the mobs fall a consistent distance everytime. All that is required to do this is to ensure that the water stream at the top of the elevator is set up like this

XXXXXXXXXX
X        X
X~~~~~S  X
XSXXXXX  X

(where ~ = water and S is a sign)

So that mobs get pushed into the drop shaft by other mobs pushing against them instead of directly by a water stream.

Minecraft – Will My Gravel Crusher Work

taken from the Wiki:

Flint is only obtainable by mining it yourself or exploding the gravel; making gravel fall onto a non-solid block (e.g. torch, sapling) does not produce flint.

The best method I found when trying to farm bunches of flint is a shovel with fortune enchant. I believe fortune 3 gurantees a flint EVERY time. So I would just build a 2x1 or 1x2 tower of however high I needed, and dig away to quickly convert all of the gravel to flint.
