# Status Effects

(diff) ← Older revision | Latest revision (diff) | Newer revision → (diff)
The 3 main status effects relevant to parkour.

Status effects can be applied from most potions, some beacon effects, or from the /effect command.

For information, the usage of the effect command is : /effect <player> <effect> <Duration> <Level-1>.

In this article, we will only detail status effects that are relevant to parkour mechanics.

For documentation of the other effects, you should consult the dedicated page on the Minecraft Wiki.

## Speed

Speed affects the Player's ground movement positively, making them move up to 20% faster per level of speed.

Speed does not change movement while airborne, therefore Sprint-Jumping becomes less and less efficient the higher the level of speed.

Here is a list of the max ground speed the Player can walk and sprint at for various speed levels.

Speed Level Max Walking Speed (b/t) Max Sprinting Speed (b/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 blocks per tick (b/t). To get the speed in m/s, simply multiply by 20.

To get the max ground speed for 45° Strafe, divide by 0.98.

## Slowness

Slowness affects the Player's ground movement negatively, making them move up to 15% slower per level of slowness.

Slowness does not change movement while airborne, therefore Sprint-Jumping becomes more and more efficient the higher the level of slowness.

Here is a list of the max ground speed the Player can walk and sprint at for various slowness levels:

Slowness Level Max Walking Speed (b/t) Max Sprinting Speed (b/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 blocks per tick (b/t). To get the speed in m/s, simply multiply by 20.

To get the max speed for 45° Strafe, divide by 0.98 (Movement Formulas if you're interested).

Notice that past level 7 (VII), Slowness completely stops the player in place.

## Jump Boost

Jump Boost affects vertical movement, rather than horizontal movement.

For reminder, 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 Relative Height (b) 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

Note: In 1.9+, the default jump height is increased to 1.252b

The duration (or airtime) is the number of ticks between jumping and landing (here on flat ground).
