This command adds the need to drink water. Every player gets their own water meter. To have the meter show up, drink some water. To keep the meter from going down (and making you die from thirst) drink water bottles, drink potions, or have your head be in water. DOES NOT WORK IN 1.9! (Command found in the 'Show source commands' button)

Put command in your world to add the noFallDamage gamerule. Type '/gamerule noFallDamage (true, false)' to turn on and off. When on, no players will take any fall damage. Side effects: jump boost potions will have no effect when the gamerule is on. This is an awesome way to get rid of fall damage, and unlike other systems, it doesn't use any resistance to work (so you can still take damage normal ways while falling, thus not breaking any PvP).

This command adds the bukkit Magic Carpet feature to your world. To activate, paste command into an impulse (normal) command block. Turn it on with a BUTTON. Once it's done, you can turn it on and off with the lever it places. After you turn it on, hold a clock to get a Magic Carpet! The clock can be in either hand. Wherever you walk or jump, it will stay under you so you don't fall. To go down with the carpet, tap crouch. Remember: This is made for 16w06a and up. It supports multiplayer. It works with other commands by me. It might cause lag. It needs a nearly-zero laggy world to work perfectly. When using high levels of speed effects, it might not work. If you have a scoreboard objective named 'Shift' (before you summoned the machine) it won't work until you delete it and re-summon the machine.
