Sentry Command Block Mod

This Project is a simple command block creation that I made on my free time. To summon a Sentry right click with a Sentry spawn egg on the floor (You will find the spawn eggs in your inventory upon loading the map). When you spawn a Sentry keep in mind a Sentry cannot be moved after being spawned so be sure of the location before you spawn your Sentry. A Sentry will kill and Spider, Zombie, Skeleton or Creeper than comes in range of the Sentry. Upon loading the map be sure to replace the Lapis block with a redstone block to start up the fill clock.
