Hey guys! I've made a one command that lets you "blink" or teleport in one command!

Instructions:

Drop a stick and an ender pearl on the ground and you get your Blink.
Sneak with the Blink Stick in your offhand to teleport forward in the direction you look.
This works in the following directions: North, South, East, West, Northwest, Northeast, Southwest, Southeast

Note: To change direction while you are blinking you need to stop blinking, look in new direction and sneak again.

Command:
