Solid block

Comparison of the solid stone and liquid water blocks

"Solid" redirects here. For about the removed command, see Commands/solid.

Solid blocks consist of any type of block that is not a liquid and cannot be walked through at the normal walking speed.

Properties

A block can be considered solid if it has a collision box that players, mobs, or other entities cannot move through and those caught inside a solid block may suffocate. For a block to be solid it also has to not be broken by flowing liquids. Blocks such as iron blocks are solid, and cobwebs are non-solid, because players can move through them slowly and water flow can break them.

The collision property of solid blocks allows block-dependent blocks and entities to be placed upon them, including:

• Painting
• Item frame
• Heads
• Signs
• Banners

Other block-dependent blocks may be placed only on full, opaque solid blocks (with a few exceptions):

• Torch
• Redstone torch
• Button
• Lever
• Ladder

Solid blocks are also considered when generating structures.

Height

Most solid blocks are 1 meter high, but certain blocks have non-standard block heights.

A player can automatically step up from a lower to a higher height, if the difference is at most 0.6 (³⁄₅) of a block. From ground level, this is anything the height of a boat or less.

A player can fit through spaces as small as 1.8125 (2 - ³⁄₁₆) blocks high, since players are 1.8 blocks tall. This allows players to fit through a 2-block gap with a floor as high as a trapdoor.

When sneaking, a player can fit through spaces as small as 1.75 (2 - ¹⁄₄) blocks high,‌ or 1.5 blocks,‌ since sneaking players are 1.65 blocks or 1.5 blocks tall, respectively. In Bedrock, this allows players to fit through a 2-block gap with a floor as high as 3 layers of snow. In Java, players can fit through a 2-block space with a floor as high as a slab.

When gliding with elytra, a player can fit through spaces as small as 0.625 (1 - ³⁄₈) blocks high, since gliding players are 0.6 blocks tall. This allows players to fit through a 1-block gap with a floor as high as 4 layers of snow, or a flower pot, or a daylight sensor.

Note that doors, although appearing to be one 2-meter-high block, are actually composed of two (top and bottom) 1-meter-high blocks.

Here is a list of blocks with non-standard heights, from tallest to shortest in height:

History

pre-classic
Cave game tech test					Added grass blocks and cobblestone, the first two types of solid blocks.
					Solid blocks were the only available type of block, until rd-161348, when the first legitimately-obtainable non-solid blocks (saplings) were added.
