Gravity blocks - Falling Entities (eg Sand) Break and Drop as Items Unexpectedly
Update by [Mojang] Mega_Spud (Jay Wells):
Summary:
Falling blocks such as sand will break even when landing on blocks that have a full height hitbox, such as hoppers, upturned stairs, or top-half slabs.
Steps to Reproduce:
- Place sand a few blocks above an upturned stair block
Observed Results:
The sand will break and drop as an item as it hits the stair block.
Expected Results:
I expected the sand to fall and land as a block, not drop as an item.
Screenshots/Videos attached: Yes
Notes:
List of blocks that cause the falling entity to break, that do not in Java:
- Hoppers
- Stair blocks (any orientation)
- Top-half slabs
- Cauldron
- Composter
- Shulker Box
- Iron Bars
- Glass Pane
- Trapdoors (iron and wooden)
- Normal Glass

- Stained Glass
- Leaves

- Ice (not packed ice)

=Fixed in 1.16
(Also happens on the following, but for a different reason: These blocks have collision box heights that are > 1 block, which would cause the gravity block to become a stuck falling block if they didn't break. Thanks to yusufulus for pointing this out.)
- Fences
- Cobblestone (and other) walls
Additional info by [MCPE Mod] Auldrick:
"Gravity block" as used here means any of the following blocks:
- Anvil
- Concrete Powder
- Dragon Egg
- Gravel
- Red Sand
- Sand
Although Scaffolding and Top Snow also fall under the influence of gravity, they behave very differently from the above and are reported in other tickets.
Original Description:
Gravity blocks are broken when they are falling on non-full blocks (wooden fences, slabs, stairs, cobblestone walls (mossy and regular) daylight sensors, end portal frame, cake, enchanting table, grasspath, hoppers, cauldrons, and hoppers). Galaxy tab 4
