Swift 如何移动精灵？

Question

I would like to know how to move a sprite in spritekit depending on the side of the screen the user is pressing down on. Like if the user taps the right side of the screen the sprite should move to the right and when the user removes his finger the sprites stops moving. Any suggestions? thank you so much

Answer 1

use the touchesBegan func and get position of touch with:

for location: AnyObject in touches {
var positionOfTouch = location.locationInNode(self)
//position of touch is of value CGPoint
}

store the value of xposition and yposition

var xPostion = positionOfTouch.position.x
var yPosition = positionOfTouch.position.y
//all in the touchesBegan func

make an if else statement to see if the user touches a side or not

if xPosition < 10 && yPosition > 10 && yPosition < self.size.height-10 {
//left side
let moveToLeftSide = SKAction.moveTo(x: 0, duration: 10)
object.run(moveToLeftSide)
}

continue setting values for the sides, then set the touchesEnded func inside the touchesEnded func, write:

object.removeAllActions()
