Blocking



Blocking is a feature implemented in the Adventure Update. When the player holds the right mouse button while wielding a sword, he or she will be able to block attacks, including arrows and explosions; blocked attacks deal only half damage. Blocking works with any sword, and does not decrease the sword's durability.

The player moves at a speed slower than the speed of sneaking when blocking while moving.



Trivia

 * The slowest possible movement in Minecraft, which can occur when the player blocks and moves forward while going through cobwebs placed on top of soulsand that is placed on top of ice, crouching and is under the effect of the slowness potion. This causes the player to move at about 1/32 blocks a second, or 1/2 pixel a second on a default 16x16 texture pack versus the 16 block per second with the previous trick. If you sneak at the same time, you go even slower, at roughly 2.385496183206e-2.
