The Elf Code

Objective

Instead of using traditional game controls, write javascript code to move the character around the game map, collect items, and interact with non-player characters.

Solution

Level 1 - Program the elf to the end goal in no more than 2 lines of code and no more than 2 elf commands.

elf.moveLeft(10)
elf.moveUp(10)

Level 2 - Program the elf to the end goal in no more than 5 lines of code and no more than 5 elf command/function execution statements in your code.

elf.moveLeft(6)
var sum = elf.get_lever(0) + 2
elf.pull_lever(sum)
elf.moveLeft(4)
elf.moveUp(10)

Level 3 - Pick up all the lollipops. Program the elf to the end goal in no more than 4 lines of code and no more than 4 elf command/function execution statements in your code.

elf.moveTo(lollipop[0])
elf.moveTo(lollipop[1])
elf.moveTo(lollipop[2])
elf.moveUp(1)

Level 4 - Program the elf to the end goal in no more than 7 lines of code and no more than 6 elf command/function execution statements in your code.

for (var i = 0; i < 5; i++) {
  elf.moveLeft(3)
  elf.moveUp(11)
  elf.moveLeft(3)
  elf.moveDown(11)
}

Level 5 - Program the elf to the end goal in no more than 10 lines of code and no more than 5 elf command/function execution statements in your code..

elf.moveTo(munchkin[0])
var array = elf.ask_munch(0)
var answer = []
array.forEach(function(item) {
  if (typeof item === 'number') {
    answer.push(item)
  }
});
elf.tell_munch(answer)
elf.moveUp(2)

Level 6 - Program the elf to the end goal in no more than 15 lines of code and no more than 7 elf command/function execution statements in your code.

for (var i = 0; i < 4; i++) {
  elf.moveTo(lollipop[i])
}
elf.moveTo(lever[0])
var list = elf.get_lever(0)
list.unshift("munchkins rule")
elf.pull_lever(list)
elf.moveDown(3)
elf.moveLeft(6)
elf.moveUp(10)

Level 7 (Bonus Level) - Program the elf to the end goal in no more than 25 lines of code and no more than 10 elf command/function execution statements in your code.

function YourFunctionNameHere(arrays) {
    var sum = 0
    arrays.forEach(function(array) {
        array.forEach(function(value) {
            if( typeof(value) == 'number') {
                sum += value
            }
        });
    });
    return sum
}

var directions = [elf.moveDown, elf.moveLeft, elf.moveUp, elf.moveRight, elf.moveDown, elf.moveLeft, elf.moveUp, elf.moveRight]

for (var i = 0; i < 7; i++) {
  directions[i](i + 1)
  elf.pull_lever(i)
}
elf.moveRight(8)
elf.moveUp(2)
elf.moveLeft(4)
answer = elf.ask_munch(0)
elf.tell_munch(YourFunctionNameHere)
elf.moveUp(1)

Level 8 (Bonus Level) - Program the elf to the end goal in no more than 40 lines of code and no more than 10 elf command/function execution statements in your code.

function YourFunctionNameHere(a) {
    for ( var x=0; x < a.length; x++ ) {
       b = a[x]
       c = Object.keys(b).find(key => b[key] == 'lollipop')
       if (typeof(c) == 'string') { 
          return c
          break
       }
    }
}

var hohoho = 0
for (var i = 0; i < 6; i++) {
  if (i % 2 == 0) {
    elf.moveRight((i * 2) + 1)
  } else {
    elf.moveLeft((i * 2) + 1)
  }
  hohoho += elf.get_lever(i)
  elf.pull_lever(hohoho)
  elf.moveUp(2)
}
elf.tell_munch(YourFunctionNameHere)
elf.moveRight(11)
