The problem with this game is that I go up against too many veterans that are screenshot artists when it comes to reoccurring questions.

Bruh waste to time video!

Awesome! Mine was a bit different: var expertMoveCounter = 0 var gemCounter = 0 var switchCounter = 0 expert.turnLeft() while expertMoveCounter == 0 || expertMoveCounter > 0 { if expert.isBlocked { expert.turnRight() } if expertMoveCounter == 5 { expert.turnLeft() expert.turnLockDown() expert.turnLockDown() } if !character.isBlocked { character.moveForward() if character.isOnGem { character.collectGem() } else if character.isOnClosedSwitch { character.toggleSwitch() switchCounter += 1 } } if expertMoveCounter == 16 { expert.turnLeft() expert.turnLockUp() } expert.moveForward() expertMoveCounter += 1 if switchCounter == 1 { break } }

Wow! ^^ I revisited my childhood!

var gem = 0 var switchcollect = 0 func ex2Move() { for i in 1 ... 2 { expert.moveForward() } } func ex3Move() { for i in 1 ... 3 { expert.moveForward() } } func expertroute() { expert.turnLeft() ex3Move() expert.turnRight() ex2Move() expert.turnLeft() if gem < 1 { expert.turnLockDown() expert.turnLockDown() }else { expert.turnLockUp() } expert.turnRight() ex2Move() expert.turnRight() ex3Move() expert.turnRight() } while switchcollect < 1 { expertroute() character.moveForward() character.moveForward() if character.isOnGem { character.collectGem() gem+=1 }else { character.toggleSwitch() switchcollect+=1 } }

var gemcollect = 0 expert.moveForward() expert.turnLockUp() while gemcollect < 2 { character.moveForward() if !character.isBlockedRight { character.turnRight() character.moveForward() character.moveForward() expert.turnLockDown() expert.turnLockDown() } if character.isOnGem { character.collectGem() gemcollect+=1 } }

var gemcollect = 0 while gemcollect < 6 { if !expert.isBlocked { expert.moveForward() } if expert.isOnGem { if gemcollect == 2 { expert.turnLockDown() } expert.collectGem() gemcollect+=1 } if !expert.isBlockedRight { expert.turnRight() expert.moveForward() } if expert.isBlocked { expert.turnLeft() expert.turnLeft() } }

var gemCollect = 0 func route() { expert.moveForward() expert.moveForward() expert.moveForward() if !expert.isBlocked && !expert.isBlockedRight { expert.turnRight() } if expert.isBlocked { if expert.isOnGem { expert.collectGem() gemCollect+=1 }else { expert.turnLockUp() } expert.turnRight() expert.turnRight() } } while gemCollect < 3 { route() }

let totalGems = randomNumberOfGems var gemCollect = 0 while gemCollect < totalGems { moveForward() if isOnGem { collectGem() gemCollect+=1 } if isBlocked { turnRight() turnRight() if pinkPortal.isActive == false { pinkPortal.isActive = true bluePortal.isActive = false } else { pinkPortal.isActive = false bluePortal.isActive = true } } }

greenPortal.isActive = false orangePortal.isActive = false var gemCollect = 0 var switchCollect = 0 while gemCollect < 6 || switchCollect < 6 { if !isBlocked { moveForward() } if !isBlockedRight { turnRight() moveForward() } if isBlocked { turnRight() turnRight() } if isOnGem { collectGem() gemCollect+=1 } if isOnClosedSwitch { toggleSwitch() switchCollect+=1 } if gemCollect == 6 && switchCollect == 2 { greenPortal.isActive = true } if switchCollect == 3 { greenPortal.isActive = false } }

This is the shortest solution I could come up with (not in code length but in time length) var switchCounter = 0 greenPortal.isActive = false orangePortal.isActive = false func walkMap() { if isOnGem{ collectGem() }else if isOnClosedSwitch { toggleSwitch() switchCounter = switchCounter + 1 } if isBlocked && !isBlockedLeft && !isBlockedRight { turnLeft() moveForward() }else if !isBlocked && !isBlockedLeft && !isBlockedRight { turnLeft() moveForward() }else if !isBlocked && !isBlockedLeft && isBlockedRight { turnLeft() moveForward() }else if !isBlocked { moveForward() }else if isBlocked && isBlockedLeft || isBlockedRight { turnLeft() turnLeft() } } while switchCounter < 6 { walkMap() if switchCounter == 2 { greenPortal.isActive = true }else if switchCounter > 2 { greenPortal.isActive = false } }

ya its not working for me the solution playground gives me doesn't work as well

So what's the difference with doing a "if is on gem"? id be simpler I think

Doesn’t work don’t waste your time on this bs

I over complicated this lol

👏

func forwardAndRight() { for i in 1 ... 5 { expert.moveForward() if !expert.isBlockedRight { expert.turnRight() } } } func forwardAndDecide() { for i in 1 ... 2 { character.moveForward() } if character.isOnGem { character.collectGem() }else if character.isOnClosedSwitch { character.toggleSwitch() } } expert.turnLeft() forwardAndRight() expert.turnLeft() expert.turnLockDown() expert.turnLockDown() forwardAndDecide() expert.turnRight() forwardAndRight() forwardAndRight() expert.turnLeft() expert.turnLockUp() forwardAndDecide()

func around() { turnLeft() turnLeft() } func walking(steps: Int) { for i in 1 ... steps { moveForward() if isOnGem { collectGem() if isBlocked { around() } } else if isOnClosedSwitch { toggleSwitch() around() } } } func turningPortals() { if greenPortal.isActive && orangePortal.isActive { greenPortal.isActive = false orangePortal.isActive = false } else if greenPortal.isActive == false && orangePortal.isActive == false { greenPortal.isActive = true orangePortal.isActive = true } } turnRight() for i in 1 ... 2 { moveForward() for i in 1 ... 3 { walking(steps: 2) turningPortals() moveForward() turnRight() walking(steps: 1) turningPortals() } }

This should not have worked. Your solution, according to the video, is incorrect. You have nested the same argument within itself...

func pat(){ while !isBlocked{ if isOnGem { collectGem() moveForward() } else if isOnOpenSwitch{ moveForward() } else if isOnClosedSwitch{ toggleSwitch() moveForward() } } } func steering(){ turnRight() moveForward() } moveForward() pat() steering() steering() pat() turnLeft() moveForward() turnLeft() moveForward() pat()

func pat(){ while isOnGem || isOnOpenSwitch || isOnClosedSwitch { if isOnGem{ collectGem() moveForward() } else if isOnOpenSwitch{ moveForward() } else if isOnClosedSwitch{ toggleSwitch() moveForward() } } } moveForward() pat() turnRight() moveForward() turnRight() moveForward() pat() turnLeft() moveForward() turnLeft() moveForward() pat()

Thank you man

let expert = Expert() var gemCounter = 0 world.place(expert, facing: south, atColumn: 1, row: 8) func searchForGems() { if expert.isOnGem { expert.collectGem() gemCounter += 1 } } while gemCounter < 9 { searchForGems() expert.moveForward() if expert.isBlocked && expert.isBlockedRight { expert.turnLockDown() expert.turnLeft() }else if expert.isBlocked && expert.isBlockedLeft { expert.turnLockUp() expert.turnRight() } }

😂 I’m a huge fan keep up the good work

while !isOnGem{ moveForward() if isOnClosedSwitch { toggleSwitch() if !isBlocked { turnRight() } else { turnLeft() } } } if isOnGem { collectGem() } that one is shorter

here is better one func collectortoggle() { if isOnGem { collectGem() } else if isOnClosedSwitch { toggleSwitch() } else if isBlocked { turnLeft() } else { moveForward() } } for i in 1 ... 20{ collectortoggle() }

Ur the best

thanks so much my code is inspired by you >>>>>> while !isOnClosedSwitch { while !isBlocked { moveForward() } turnRight() } toggleSwitch()

the outer loop "!isBlocked" is false when character at the corner.how it works?

Slow down next time please you were way too quick.

ty

Solved with the loop guys. func collectOrToggle() { for i in 1 ... 4 { moveForward() if isOnClosedSwitch { toggleSwitch() } else if isOnGem { collectGem() } } collectOrToggle() turnLeft() moveForward() moveForward() turnLeft() collectOrToggle() turnRight() moveForward() turnRight() collectOrToggle()

How about that? func moveAndCollect() { for i in 1 ... 2 { moveForward() collectGem() } } func moveAndSwitch() { for i in 1 ... 2 { moveForward() toggleSwitch() } } func turnAround() { turnLeft() turnLeft() } func moveTwice() { moveForward() moveForward() } func turnAndMove() { turnRight() moveForward() } func turnMoveTurn() { turnRight() moveForward() turnRight() } for i in 1 ... 3 { turnRight() moveAndCollect() turnAround() moveTwice() turnAndMove() } turnAround() moveForward() turnRight() for i in 1 ... 3 { moveAndSwitch() turnAround() moveTwice() turnMoveTurn() }

1:43 how do i add the else if statement on mac?

This puzzle DOES NOT WORK! I do EXACTLY as you say by typing "if isOnGem in the function box at 0:32 and immediately I get the red error dot. I'm absolutely stuck. I can't do this Swift Playground thing anymore until I can get beyond this horrible difficulty.

why is everyone pretending this isnt gateway porn?

**This is how I done it while !isOnGem { if isOnClosedSwitch { toggleSwitch() } else { moveForward() } while isBlocked && isBlockedLeft { turnRight() } } collectGem()

func navigateAroundWall(){ if isBlocked && isBlockedRight { turnLeft() } else if isBlockedRight { moveForward() } else { turnRight() moveForward() } } while !isOnClosedSwitch { navigateAroundWall() if isOnGem { collectGem() } } toggleSwitch()

It works, thanks! Slightly less version 👇🏼 for i in 1 ... 4 { moveForward() if !isOnGem{ turnLeft() moveForward() moveForward() collectGem() turnRight() turnRight() moveForward() moveForward() turnLeft() }else { collectGem() } }

greenPortal.isActive = false var numberOfSwithes = 0 while numberOfSwithes != 3 { moveForward() if isOnClosedSwitch { toggleSwitch() numberOfSwithes += 1 } if isBlocked && isBlockedLeft && isBlockedRight { turnLeft() turnLeft() } if !isBlocked && !isBlockedLeft && !isBlockedRight{ turnLeft() } }

like years later there's me here to comment this doesn't work 😃 no offense ofc :)

while !isBlocked{ moveForward() if isOnGem{ collectGem() turnLeft() } else { turnRight() } }

don't write toggleSwitch inside the loop

Is this solution ok? func CollectorToggle() { if isOnClosedSwitch { toggleSwitch() } else if isOnGem { collectGem() } else if isBlocked && isBlockedLeft { turnRight() } } while !isBlocked { moveForward() CollectorToggle() }

how is this from by 2016 on an iPad when playgrounds came available in it in 2021

OMG I did everything correctly I just changed the number of times from 16 to 5 and how is this guy using playgrounds on an iPad in 2016 when it came available in 2021?

that's so weird I wrote this same code but put it in a function to simplify and it wouldn't work.

BRUH THAT’S JUST NOT A PROGRAMMING
