Random Gems Everywhere

let totalGems = randomNumberOfGems

var gemCon = 0

func navigate () {
    while !isBlocked {
        moveForward()
        if isOnGem {
            collectGem()
            gemCon += 1
        }
    }
}

func turnOffPortals() {
    bluePortal.isActive = false
    pinkPortal.isActive = false
}
func turnOnPortals() {
    bluePortal.isActive = true
    pinkPortal.isActive = true
}

func turnAround() {
    turnRight()
    turnRight()
}

while gemCon < totalGems {
    navigate()
    turnAround()
    turnOffPortals()
    navigate()
    turnAround()
    turnOnPortals()
}

This is simple but cleaver soloution
Also If you add FUNC to it,it will be much better,
anyway:

let totalGems = randomNumberOfGems

var gem = 0

while gem < totalGems {
moveForward()
if isOnGem {
collectGem()
gem += 1
}
if isBlocked {
turnRight()
turnRight()
if pinkPortal.isActive == false {
pinkPortal.isActive = true
bluePortal.isActive = false
}else{
pinkPortal.isActive = false
bluePortal.isActive = true
}
}
}
