Thing type 541, Gas Jet, is a type of Thing that intermittently spawns spurts of gas in a regular interval. Players or pushables standing on this Thing will be launched into the air when the gas is spawned. The gas jet propels the player 434 fracunits into the air, slightly less than a yellow spring. To make platforms reachable by a gas jet, it is recommended to make them no higher than 384 fracunits from the ground to provide a little extra room.
