What is a function?​

A function is a group of code that is put together and given a name so that it can be reused very easily.

Simple example​

This function will say "Hello World!" to everyone when you run it in Minecraft.

function hello() {
  console.log("Hello World!");
}

What can functions do?​

Functions are for blah blah

More examples​

Here, Huyang uses the build_pillar() function to avoid repeating the code needed to build a tower of blocks.

var Huyang = new vMod.Drone()

function build_wall() {
  for (var j = 0; j < 7; j++) {
    build_pillar()
  }
}

function build_pillar() {
  for (var k = 0; k < 3; k++) {
    Huyang.setblock('~ ~ ~', 'yellow_wool')
    Huyang.moveUp(1)
  }
  Huyang.moveDown(3)
  Huyang.moveForwards(1)
}
