swift / spritekit move then touch element - ios

Question

I'm currently working on a game in swift using spritekit. I've got my joystick working using this library, and thats all good. I'm also moving the joystick to where the user taps using this code:
func updateJoystickPosition(pos: CGPoint) {
let posX = -(self.sceneSize.width/2) + pos.x
let posY = (self.sceneSize.height/2) - pos.y
let newJoystickPos = CGPoint(x: posX, y: posY);
self.joystick.position = newJoystickPos
}
which also works just fine, however, the joystick doesn't engage on that one tap. You have to tap on the actual joystick node for the joystick to engage, so obviously, i'd want the user to put their finger down on the screen and immediately be able to start moving it around to move the player.
the joystick it's self starts tracking with this function
open override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
print(touches)
if let touch = touches.first, stick == atPoint(touch.location(in: self)) {
tracking = true
startHandler?()
}
}
Question: Is there anyway i can modify the touchesBegan function or any of my other functions to achieve the desired results?

Answer 1

You have to override touchesMoved(_ touches: ,with event:) and in this method just processing all touches.
For example:
var startTouchingPoint = CGPoint.zero // property
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
for touch in touches {
startTouchingPoint = touch.location(in: self.camera!))
yourControllerPlace.position = startTouchingPoint
stickOnYourJoystick.position = CGPoint.zero
}
}
override func touchesMoved(_ touches: Set<UITouch>, with event: UIEvent?) {
for touch in touches {
let point = touch.location(in: self.camera!))
let convertedPoint = CGPoint(x: point.x - startTouchingPoint.x,
y: point.y - startTouchingPoint.y)
stickOnYourJoystick.position = convertedPoint
}
}
