Sprinting

Sprinting is a feature in Beta 1.8, which allows the player to run 30% faster, or around 5.6 meters/second. The player sprints by double tapping the "Forward movement" key ( by default) and then holding it. It will be possible to jump across four blocks horizontally (instead of the usual two blocks) by sprinting, however the jump will be no higher than normal. Whilst sprinting, the player is able to clear gaps of one block without jumping.

Sprinting is unlimited as long as the Food Bar is above 30%, but it will also deplete the bar at a rate of 1/2 a food unit every 40 meters, or 7 seconds, as long as the foodSaturationLevel is at 0. When a player sprints, particles will come from the player's feet corresponding to the block type they are running on. When a player attacks any mobs (excluding squid) while sprinting, the mob will fly back.

Sprinting stops when you collide with a solid block, or perform a sneaking action such as blocking. You do not stop sprinting when you run into a mob. Also, the player will not be ignited when you run through up to four consecutive blocks of fire (the fifth block will ignite the player). It is possible to make turns while sprinting without leaving the sprinting state of the player, thus altering the direction of where you go.

After switching in the "sprinting state" the field of view also slightly changes and the camera moves back to give the player more view of the terrain. If you turn the FOV to the max (Referred to as "Quake Pro") and sprint, when you look down, it appears as if the player is above ground.

Bugs

 * Sprinting and jumping while in a 2 block high tunnel or house will cause a speed almost twice as high as regular sprinting speed. This is rather inefficient however, as this can easily drain food at a rate of about 1 unit per second.
