I'm unable to move my sprite left or right when the screen is touched. I'm just starting this game and I can't even get it to work. I've had this problem for a few days and it's getting really frustrating.
GameplayScene.swift
import SpriteKit
class GameplayScene: SKScene {
var player : Player?
var canMove = false
var moveLeft = false
var center : CGFloat?
override func didMoveToView(view: SKView) {
center = (self.scene?.size.width)! / (self.scene?.size.height)!
player = self.childNodeWithName("Player") as? Player!
}
override func update(currentTime: NSTimeInterval) {
managePlayer()
}
override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
for touch in touches {
let location = touch.locationInNode(self)
if location.x > center {
moveLeft = false
} else {
moveLeft = true
}
}
canMove = true
}
override func touchesEnded(touches: Set<UITouch>, withEvent event: UIEvent?) {
}
func managePlayer() {
if canMove {
player?.movePlayer(moveLeft)
}
}
}
Player.swift
import SpriteKit
class Player: SKSpriteNode {
func movePlayer(moveLeft: Bool) {
if moveLeft {
self.position.x = self.position.x - 7
} else {
self.position.x = self.position.x + 7
}
}
}
在touchesEnded
函数中设置canMove = false
