CreativeFlight is a Minecraft hack that allows the user to fly by double-tapping the jump button¹⁾, as if the player was in Creative Mode.

Servers where flying is not enabled will attempt to kick the user for using CreativeFlight, but they can only detect that CreativeFlight 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 ~0.032m²⁾, 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.

When this checkbox is checked, CreativeFlight 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”.

This setting determines how often CreativeFlight 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.

This setting determines how far CreativeFlight 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.
