This is a "only one command block" device that when placed will allow any entity named "1" to follow a track 2 blocks
below the entity (The block under the block it's standing on)
___________________________________________________________________________________________________________

HOW TO USE: To use this device you'll need to know which direction is which so press the "F3" key and look for the word South, North, East, or West.

For south use yellow (slow movement), lime green (fast), green (fastest), and blue (used after a turn) Wool

For east use yellow (slow movement), lime green (fast), green (fastest), and light blue (used after a turn) Terracotta

For north use yellow (slow movement), lime green (fast), green (fastest), and blue (used after a turn) Concrete

For west use yellow (slow movement), lime green (fast), green (fastest), and blue (used after a turn) Stained Glass

For turning east use a white wool block

For turning north use a light gray wool block

For turning west use a gray block

For turning south use a black wool block

The following command needs to be placed into a command block and then activated and then you will have the machine built
