That code allows other players to use moonjump capabilities without the use of cheating. All you need to do is turn that code on and they will be able to use their flamethrowers like a jetpack.
Although this may seem unfair (since anything below 65 can not really use a flamethrower there are glitches one can do to get a flamethrower at level 4. thats the great thing about youtube)

for X's put a floating point, do not make it too loud. I'm pretty sure it caps out around 100x normal
3F800000 is default...

Turn Speed Modifier: [hetoan2]
04672298 XXXXXXXX
For X's put a floating point value converted to hex. If you want something a little faster than the maximum in-game one, you might want to try 3FC00000 (1.5x normal) All others are too fast really. If you make it go too fast, the game will turn off the turn function and will make your viewpoint fixed for the rest of the game
