// basic Commands:
// step();              lets your robot walk one block
// set();               lets your robot place a block
// turnRight();         lets your robot turn Right
// turnLeft();          lets your robot turn Left
// sendCommand("s");    executes a command inside Minecraft (s = to execute [e.g. /say tree])
// sleep(1000);         sleeps 1000 milliseconds (=1sec.) you can also use different Numbers [like sleep(2345);]
// turnRight() and turnLeft() don't work yet!


//  of course you can also use if conditions, while loops and so on. Don't worry if you don't know what that is :)
//  if you want to learn how to use those, just google "javascript tutorial for beginners" or something like that

//write your RobotSteve Minescript code below


//Code Example: (remove it if you want to create your own :) )
