As the title suggests if a mob walks over a block that is covered by a pressure plate as it wanders or pathfinds it will start to jump as it moves. It happens to every mob that is 1 block wide and walks without jumping already. It does happen on all pressure plates.
- Place a ring of 8 pressure plates on top of solid blocks, leaving a center block with no pressure plate on top.
- Spawn a zombie in the middle of the ring, on the block without a pressure plate.
- Spawn a villager outside of the ring.
The zombie walks toward the villager.
The zombie jumps when pathing over the pressure plates.
