Hello,I'm working on a game that is controlled by swipes. I have the following function to track pan swipes:@objc func handlePanFrom(_ recognizer: UIPanGestureRecognizer) {
if recognizer.state != .cancelled {
let translation = recognizer.translation(in: recognizer.view)
// TODO: use the x and y coordinates of endPoint and beginPoint to determine which direction the swipe occurred.
let xDif = translation.x
let yDif = translation.y
if abs(xDif) > abs(yDif) {
if xDif > 0 {
changeDirection(direction: .east)
print("change east")
} else {
changeDirection(direction: .west)
print("change west")
}
} else if abs(yDif) > abs(xDif) {
if yDif > 0 {
changeDirection(direction: .south)
print("change south")
} else {
changeDirection(direction: .north)
print("change north")
}
}This will track the user's swipes and change the direction effectively, but only if the user lets go of the screen after every swipe. I was wondering, is there a way to "reset" the translation positions every time the direciton is changed so the user does not have to release from the screen after swiping? I tried calling recognizer.setTranslation(CGPointZero, inView: self.view) every time the direction is changed, but that didn't work.
