This is a fun little plugin I made that uses a simple command to launch a player. It will launch the player in the direction they are facing. This can also be used with command blocks to create launch pads, like the aerial faith plate from Portal.
But wait, what about fall damage?
Not to worry, this plugin also allows wool to negate all fall damage. As a bonus, if you use sponge, it will also bounce you when you fall on it.
HOW TO USE:
The Command is: "/launch <player> <velocity> <y add> [ignore pitch] [loop time]"
<player>,<velocity>, <y add> are necessary
How do I make a launch pad?
Simple. Get a command block, put a pressure plate above it, and use a command such as: "/launch @p 5 2" When the player walks over it, it will launch them in the air.
