Sprite-Kit Variable won't stop adding - swift

Question

In my game I am trying to add 1 to a variable score every time certain conditionals happen in my update function. The problem is that the update function is called every frame so my score variable just keeps climbing into the hundreds when it should be going up by 1 slowly. Here is my code:
override func update(_ currentTime: TimeInterval) {
if circleStart.frame.width >= self.frame.width && userTouched == false{
hasTouchedEdge = true
}
if hasTouchedEdge == true && userTouched == false {
scaleSpeed -= 0.2
}
if scaleSpeed <= 1.0 && userTouched == false {
scaleSpeed += 0.3
hasTouchedEdge = false
}
if userTouched == false{
scaleSpeed += 0.1
circleStart.setScale(CGFloat(scaleSpeed))
circleLength = circleStart.frame.width
acceptableBound1 = outerCircle.frame.width
acceptableBound2 = outerCircle.frame.width - 100
}
if userTouched == true && circleLength > acceptableBound2 && circleLength < acceptableBound1{
print("worked")
isCorrect = true
}
if userTouched == true && circleLength > acceptableBound1 {
gameOverLabel.isHidden = false
playAgain.isHidden = false
playAgain.run(fadingTapIn)
}
if userTouched == true && circleLength < acceptableBound2{
gameOverLabel.isHidden = false
playAgain.isHidden = false
playAgain.run(fadingTapIn)
}
if isCorrect == true {
score += 1
}
scoreLabel.text = String(score)
}
What do I need to do or add to have my score variable work in my desired way explained above?

Answer 1

Easy solution:
Add isCorrect = false after score += 1.
Good solution:
Try removing most of that code in update. Update is called nearly 60 times per second in most cases and it is not the best place to make changes for a few reasons.
Try using
override func touchesBegan(touches: Set<UITouch>,with event: UIEvent?) {
for touch in touches {
let location = touch.location
if (someNode.contains(location)) {
//This if statement isn't needed, but an example of how you can determine if a node was pressed
someFunctionToDoStuff(location)
}
}
}
or
override func touchesBegan(touches: Set<UITouch>,with event: UIEvent?) {
let touch = touches.first
let location = touch.location
if (someNode.contains(location)) {
//This if statement isn't needed, but an example of how you can determine if a node was pressed
someFunctionToDoStuff(location)
}
}
The first option may run multiple times depending on how many touches were determined. The second option will only pay attention to the first touch it notices and disregard the rest.
You can define this function however you like, just make sure to take the location of the touch if you need it:
func someFunctionToDoStuff(_ location: CGPoint) {
score += 1
// Then maybe move a node to where the press was located
ball.position = location
}
You can use touchesBegan, touchesMoved, and touchesEnded as functions.
