Jumping

Jumping is a mechanic that elevates the player 1 block into the air. It also has other effects when combined with another forms of movement.

Activation
Jumping is done by pressing the key (which defaults to the space bar on PC) or the jump button on other devices.

Jump height changes
Jumping normally lets the player climb up 1$1/4$ block. Players with Jump Boost I are able to jump 1$15/16$ block, and with Jump Boost II they are able to jump 2$1/2$ blocks. The effect also increases more with more levels of Jump Boost.

Honey blocks make players jump from them $3/16$ block, meaning that they get an 85% jumping reduction.

Cancellation
Cobwebs and sweet berry bushes prevent players from jumping from them.

Sneaking and crawling, when activated by suffocation prevention $$, prevent players from jumping due to the reduced space. These two actions normally do not prevent players from jumping.

Combinations
Jumping can be combined with sprinting to increase the player's movement speed. This also reduces the hunger bar faster.

Other mobs
Certain mobs are able to jump:


 * Villagers (but they prefer not to jump)
 * Illagers (when celebrating a successful raid)
 * Most other mobs.
 * This is only the case if the player is luring the mob, or if the mob is hostile. If the mob flies, or is stationary, or is a water mob (except (elder) guardians and turtles).
 * Fish flop around, not jump.

Trivia

 * Jumping was one of the first transportation mechanics added.
 * Jumping is one of the most used and the most versatile transportation mechanics.
 * The highest possible distance someone can jump is 5 blocks. Though there are various factors that are needed to preform this.
 * Without momentum, it is 4 blocks.
