Speed
Speed increases the player's ground speed, making them move 20% faster per level of speed.
Speed does not affect movement while airborne, therefore sprint-jumping becomes less efficient the higher the level of speed (for Speed II, it is generally slower to sprint-jump than to simply run)
Speed Level | Max Walking Speed (m/t) | Max Sprinting Speed (m/t) |
---|---|---|
None | 0.215 | 0.280 |
I | 0.259 | 0.336 |
II | 0.302 | 0.392 |
III | 0.345 | 0.448 |
IV | 0.388 | 0.505 |
The speed is presented in meters per tick (m/t). To get the speed in m/s, simply multiply by 20.
To get the max ground speed with 45° Strafe, divide by 0.98.
Slowness
Slowness slows the player's ground speed, making them move 15% slower per level of slowness.
Slowness does not change movement while airborne, therefore sprint-jumping is more efficient.
Slowness Level | Max Walking Speed (m/t) | Max Sprinting Speed (m/t) |
---|---|---|
None | 0.215 | 0.280 |
I | 0.183 | 0.238 |
II | 0.151 | 0.196 |
III | 0.118 | 0.154 |
IV | 0.086 | 0.112 |
V | 0.053 | 0.070 |
VI | 0.021 | 0.028 |
VII | 0.000 | 0.000 |
The speed is presented in meters per tick (m/t). To get the speed in m/s, simply multiply by 20.
To get the max ground speed with 45° Strafe, divide by 0.98
Note: past level 7 (VII), Slowness completely stops the player in place.
Speed and Slowness Interaction
Speed and Slowness multipliers do not add, but rather multiply.
For example, if the player has Speed III (+60%) and Slowness IV (-60%), the resulting speed effect is not +0% as one could expect, but -34%.
Jump Boost
Jumping sets the player's vertical speed to 0.42 by default.
The jump boost effect increases this initial vertical boost by 0.1 per level.
Here is a list of the max height the player can reach for various speed levels.
Jump Boost Level | Max Height (m) | Duration (t) on flat ground |
---|---|---|
None | 1.249 | 12 |
I | 1.836 | 14 |
II | 2.516 | 16 |
III | 3.290 | 19 |
IV | 4.153 | 21 |
V | 5.103 | 23 |
Notes:
- In 1.9+, the default jump height is increased to 1.252m, but that does not change the jump height with jump boost in general (see Movement Formulas).
- Past level 129, Jump Boost becomes negative, which makes the player unable to jump (unless they use the negative speed to bounce on a slime block).
- Levels 252 - 256, the player is able to jump again, but with reduced jump height. Level 256 has the same jump height as the default.
