Swift — Crank Up and Down

Objective: Initialize two monsters, then have one collect all gems with the other moving platforms up and down as needed.

My assumption was to start with top left gems and then move down to lower level before finishing with far right top level. A bit heavy handed when it came to running the code — do this, then do that — with far less func’s than I’d preferred.

I suspected there was a better way, and this solution proves it. By completing the entire top level first and then moving down to complete the lower level it’s possible to complete with 30% less code!

My solution

let expert = Expert()
let character = Character()
func turnLock(up:Bool, turns: Int) {
if up == true {
for i in 1…turns {
expert.turnLockUp()
}
} else {
for i in 1…turns {
expert.turnLockDown()
}
}
expert.turnRight()
}
func getGem(move: Int) {
for i in 1…move {
character.moveForward()
}
if character.isOnGem {
character.collectGem()
}
character.turnRight()
character.turnRight()
}
func moveFwd(move: Int) {
for i in 1…move {
character.moveForward()
}
character.turnLeft()
}
getGem(move: 2)
character.turnLeft()
turnLock(up: true, turns: 4)
getGem(move: 2)
moveFwd(move: 1)
character.turnRight()
character.turnRight()
expert.turnLeft()
turnLock(up: false, turns: 3)
getGem(move: 1)
moveFwd(move: 2)
turnLock(up: true, turns: 1)
getGem(move: 2)
moveFwd(move: 2)
moveFwd(move: 2)
turnLock(up: true, turns: 1)
getGem(move: 2)
moveFwd(move: 2)
turnLock(up: true, turns: 1)
getGem(move: 2)
moveFwd(move: 1)
expert.turnLeft()
turnLock(up: true, turns: 3)
moveFwd(move: 1)
character.turnLeft()
getGem(move: 2)

Jyjy Game solution

let expert = Expert()
let character = Character()
var gemCounter = 0
func checkGem() {
if character.isOnGem {
character.collectGem()
gemCounter += 1
}
}
for i in 1…4 {
expert.turnLockUp(up: true, numberOfTimes: 4)
expert.turnLeft()
}
while gemCounter < 3 {
character.move(distance: 2)
if !character.isBlockedRight {
character.turnRight()
}
checkGem()
}
character.moveForward()
for i in 1…4 {
expert.turnLock(up: false, numberOfTimes: 3)
expert.turnLeft()
}
character.turnLeft()
character.moveForward()
checkGem()
while gemCounter < 7 {
if !character.isBlockedRight {
character.turnRight()
} else if character.isBlocked {
character.turnLeft()
character.turnLeft()
}
character.move(distance: 2)
checkGem()
}
