我有一个问题，为什么我的SpriteKit节点没有从下面的代码中从我的父节点中删除。SpriteKit节点没有被从父节点删除
我的项目目前有两个部分，一个是GameScene类，它在您创建SpriteKit项目时出现默认值，另一个是我在游戏中的每个圆上操作的Circles类。
的圆圈被存储在数组中的位置：
var circlesInPlay = [Circles]()
基本上，我试图设计一简单的游戏，圆圈尺寸减小，并且当它们是0宽度的，从屏幕除去。
我的代码要做到这一点就在这里，在
override func update(currentTime: CFTimeInterval) {
timeSinceUpdate = timeSinceUpdate + 1
print("time since update: " + String(timeSinceUpdate))
if timeForUpdate == timeSinceUpdate {
newCircle()
timeSinceUpdate = 0
//timeForUpdate = Int(arc4random_uniform(100) + 1)
timeForUpdate = 100
}
//Check to see if circle transparancies are 0
if checkGameOver() {
gameOver()
}
updateCircles()
removeCircles()
的timeSinceUpdate变量是自上次圈已经被放置到屏幕上，它通过一个每帧更新增加了时间。
updateCircles（）调用此，
func updateCircles() {
for c in circlesInPlay {
c.update()
}
}
其中要求在圆类我在另一个迅速文件进行更新（）：
func update() {
transparancy = transparancy - transparancyDecrease
size = size - ds
if (size <= 0) {
node.removeFromParent()
}
node.size.height = size
node.size.width = size
}
从更新功能的其他调用removeCircles（ ）在这里
func removeCircles() {
var posn = circlesInPlay.count - 1
for c in circlesInPlay {
if (c.size < 0) {
c.produceNode().removeFromParent()
circlesInPlay.removeAtIndex(posn)
posn = posn - 1
}
}
}
我真的得到的是我不知道为什么圈子是索姆etimes卡住或没有被从屏幕上移除。
任何帮助，非常感谢！
整个游戏代码如下：
import SpriteKit
class GameScene: SKScene {
var bgImage = SKSpriteNode(imageNamed: "background.png")
let screenSize = UIScreen.mainScreen().bounds
var timeSinceUpdate: Int = 0
var circlesInPlay = [Circles]()
var timeForUpdate = Int(arc4random_uniform(200) + 1)
override func didMoveToView(view: SKView) {
bgImage.position = CGPointMake(self.size.width/2, self.size.height/2)
bgImage.zPosition = -100
self.addChild(bgImage)
}
override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
/* Called when a touch begins */
for touch in touches {
let location = touch.locationInNode(self)
if !isTouchInCircle(location) {
gameOver()
}
}
}
override func update(currentTime: CFTimeInterval) {
/* Called before each frame is rendered */
timeSinceUpdate = timeSinceUpdate + 1
print("time since update: " + String(timeSinceUpdate))
if timeForUpdate == timeSinceUpdate {
newCircle()
timeSinceUpdate = 0
//timeForUpdate = Int(arc4random_uniform(100) + 1)
timeForUpdate = 100
}
//Check to see if circle transparancies are 0
if checkGameOver() {
gameOver()
}
updateCircles()
removeCircles()
}
func newCircle(){
let sizeX = UInt32(CGRectGetMaxX(self.frame))
let randomx = CGFloat(arc4random_uniform(sizeX))
let sizeY = UInt32(CGRectGetMaxY(self.frame))
let randomy = CGFloat(arc4random_uniform(sizeY))
//let randomx = CGFloat(arc4random_uniform(UInt32(self.size.width)))
//let randomy = CGFloat(arc4random_uniform(UInt32(self.size.height)))
if (circlesInPlay.count < 5) {
circlesInPlay.append(Circles.init(x: randomx, y: randomy))
self.addChild((circlesInPlay[circlesInPlay.count - 1]).produceNode())
}
}
func checkGameOver() -> Bool {
for c in circlesInPlay {
if c.getTransparancy() == 0 {
return false
}
}
return true
}
func isTouchInCircle(touch: CGPoint) -> Bool {
for c in circlesInPlay {
if (c.getX() <= (touch.x * 1.10)) {
return true
}
}
return false
}
func updateCircles() {
for c in circlesInPlay {
c.update()
}
}
func removeCircles() {
var posn = circlesInPlay.count - 1
for c in circlesInPlay {
if (c.size < 0) {
c.produceNode().removeFromParent()
circlesInPlay.removeAtIndex(posn)
posn = posn - 1
}
}
}
func gameOver() {
}
}
import Foundation
import SpriteKit
import GameKit
class Circles {
var node = SKSpriteNode()
var size: CGFloat = 200
var ds: CGFloat = 2
var colorC: String;
var xpos: CGFloat
var ypos: CGFloat
var transparancy: Int
var transparancyDecrease: Int = 1
let arrayColors = ["circleRed.png", "circleBlue.png", "circlePink.png", "circleGreen.png", "circleYellow.png"]
//The innitial constructor
init(x: CGFloat, y: CGFloat) {
self.xpos = x
self.ypos = y
self.transparancy = 100
let randomIndex = Int(arc4random_uniform(UInt32(arrayColors.count)))
colorC = arrayColors[randomIndex]
node.texture = SKTexture(imageNamed: colorC)
node.position = CGPointMake(self.xpos, self.ypos)
node.size.height = self.size
node.size.width = self.size
}
func produceNode() -> SKSpriteNode {
return node
}
func setColor() {
let randomIndex = Int(arc4random_uniform(UInt32(arrayColors.count)))
colorC = arrayColors[randomIndex]
}
func update() {
transparancy = transparancy - transparancyDecrease
size = size - ds
if (size <= 0) {
node.removeFromParent()
}
node.size.height = size
node.size.width = size
}
func getX() -> CGFloat {
return xpos
}
func getY() -> CGFloat {
return ypos
}
/*
func getColor() -> SKColor {
return colorC
}*/
func getTransparancy() -> Int {
return transparancy
}
}
如果c.size <= 0 {...}而不是c.size <0，则在removeCircles（）方法中。 – Whirlwind
