Using Flight.
In-game description“Allows you to fly.

WARNING: You will take fall damage if you don't use NoFall.”
Default keybindG
Source codenet/wurstclient/hacks/FlightHack.java

The Flight hack allows the user to fly around and reach places they normally couldn't. As the in-game description says, Flight should be used together with NoFall to avoid taking fall damage.

Servers where flying is not enabled will attempt to kick the user for using Flight, but they can only detect that Flight is being used if the player isn't moving down for at least 4 seconds (80 ticks). Every time the player moves down by at least ~0.032m1), the four-second timer starts over again. With a bit of practice or use of the Anti-Kick feature, it is possible to fly around indefinitely without getting kicked.


Horizontal Speed

Horizontal Speed
In-game description(none)
Default value1

This setting determines how fast the Flight hack moves the player horizontally when the W, A, S or D keys are pressed.

Vertical Speed

Vertical Speed
In-game descriptionWARNING: Setting this too high can cause fall damage, even with NoFall.”
Default value1

This setting determines how fast the Flight hack moves the player up and down when the jump or sneak key is pressed.

Slow sneaking

Slow sneaking
In-game description“Reduces your horizontal speed while you are sneaking to prevent you from glitching out.”
Default valuechecked

When this checkbox is checked, Flight will reduce the player's horizontal speed to 0.85 while the player is sneaking. This prevents the player from rubber-banding back and forth when flying forward and down at the same time.


In-game description“Makes you fall a little bit every now and then to prevent you from getting kicked.”
Default valuenot checked

When this checkbox is checked, Flight will make the player fall for a short time, at an interval determined by the “Anti-Kick Interval” setting and a distance determined by the “Anti-Kick Distance” setting. This prevents the player from getting kicked with the message “Flying is not enabled on this server”.

Anti-Kick Interval

Anti-Kick Interval
In-game description“How often Anti-Kick should prevent you from getting kicked.
Most servers will kick you after 80 ticks.”
Default value30 ticks
Minimum5 ticks
Maximum80 ticks
Increment1 tick

This setting determines how often Flight will make the player fall. The default value of 30 ticks means that the player will fall every 1.5 seconds, which is rather conservative since most servers will wait as much as 80 ticks (4 seconds) before kicking the player.

As long as the server is not lagging too badly, values as high as 70 ticks (3.5 seconds) are still safe to use and will be much less noticeable to the user.

Anti-Kick Distance

Anti-Kick Distance
In-game description“How far Anti-Kick should make you fall.
Most servers require at least 0.032m to stop you from getting kicked.”
Default value0.07m (7cm)
Minimum0.01m (1cm)
Maximum0.2m (20cm)
Increment0.001m (1mm)

This setting determines how far Flight will make the player fall when the “Anti-Kick” setting is enabled. The default value of 0.07m (7cm) is again rather conservative, since most servers will only require a fall distance of 0.032m (3.2cm) to prevent the player from getting kicked.

Decreasing this value to about 0.034m (3.4cm) will make the Anti-Kick feature less noticeable to the user and still be safe to use on most servers. However, some users may prefer the noticeable jump caused by the default value, as it provides a visual indication that the Anti-Kick feature is working correctly.
