ios - How do I change the direction of an object with swipe? -

i made path object , keeps repeating time. need object stop action , move @ direction swipe (up, down, right, left). after stopping , moving in swipe direction, need object resume path when touching it.

this code:

 import spritekit      class gamescene: skscene {      // functions defines happen when doing swipes     // in different directions.      // player.removeactionforkey("trailrunning") stops     // skaction.repeatactionforever path created     // object. trailrunning keyword created     // manipulate whether action should continue or not.      func swipedright(sender:uiswipegesturerecognizer){         println("swiped right")          player.removeactionforkey("trailrunning")      }      func swipedleft(sender:uiswipegesturerecognizer){         println("swiped left")          player.removeactionforkey("trailrunning")      }      func swipedup(sender:uiswipegesturerecognizer){         println("swiped up")          player.removeactionforkey("trailrunning")      }      func swipeddown(sender:uiswipegesturerecognizer){         println("swiped down")          player.removeactionforkey("trailrunning")      }      var bg = skspritenode()     var player = skspritenode()      // created startposition objects path      let startposition = cgpointmake(20, 20)      // pathrunning not relevant here, i'm using "start"     // game.      var pathrunning = 0       override func didmovetoview(view: skview) {         /* setup scene here */          // tells there no gravity          self.physicsworld.gravity = cgvectormake(0, 0)          // making swipes possible          var swiperight:uiswipegesturerecognizer = uiswipegesturerecognizer(target: self, action: selector("swipedright:"))         swiperight.direction = .right         view.addgesturerecognizer(swiperight)           var swipeleft:uiswipegesturerecognizer = uiswipegesturerecognizer(target: self, action: selector("swipedleft:"))         swipeleft.direction = .left         view.addgesturerecognizer(swipeleft)
