Jetpack

Flying upward while you hold a key, as long as you have fuel, on maps built for it.

How it works#

Keythe jetpack key, held
Thrustan upward push of 1000–1200 ups/s (set by the map), more than gravity's 800, applied every movement step; your upward speed is capped
Air controlnormal air strafing while you fly
Fuelseconds of thrust, shown on the HUD; refilled by fuel pickups or on landing, as the map decides

In maps#

  • Fuel pickups of different sizes, refuel zones, and no-fly zones.
  • Fuel is the limit: the skill is when you burn it.
  • Tribes-style: ski down an icy slope, jet up the next one. Speed and height, traded back and forth.

Where it comes from#

The UJM map ut4_jetjumps_b3 built a jetpack out of server triggers: hold Walk to fly, 25 ups upward about every 24 ms while rising slower than 450 ups, fuel boxes of different colours that don't stack, and a fuel box that also saves your position. Airtime's jetpack is the same idea, built into the movement itself, so it's smooth at every frame rate and replays exactly.
