Player movement

Jumping is how players and mobs go up blocks. Players and most mobs can jump up 1 block at a time (more precisely, 1.252). Jumping is not needed for differences in height of 1/2 block or less. The default key for jumping is the space bar, which is also used for swimming. Jumping uses more hunger than walking. Sprinting and jumping is faster than normal sprinting, but it uses much more hunger.

Players move at a speed of 4.317 m/s while on flat ground. Sprinting increases this to 5.612 m/s. Players flying in creative mode reach a speed of 10.89 m/s.

Trivia

 * Jumping then holding the spacebar in Creative Mode is how you fly. Flying is an easy way to get around, as you can cover vast distances quickly.
 * The player (and most mobs) jumps about 1.252 blocks high.
 * The Jump Boost status effect increases this to 1.836 blocks, and Jump Boost II increases it to 2.517 blocks.
 * Spiders jump to attack, but these jumps only raise them to a height of 1.153 blocks.
 * Slimes and Magma Cubes move only by jumping.
 * Magma Cubes' jump height depends on their size: 1.836, 2.517, and 4.154 blocks for tiny, small, and large respectively.
 * The number of jumps you make is recorded in Statistics.
 * Jumping on crops can harvest them, but at the cost of turning farmland back into dirt.
 * If you press "Q"(The default key for dropping the selected item, tool, or block in the Hotbar) while holding multiple items or blocks, while in midair, you drop everything you have selected.
