加速度计介绍？代码修复？
最新错误：
我最近一直在开发一个带有教程的应用程序，并且我希望转向教程。但我接下来没有SpriteKit的经验，所以我想帮助使用加速计来控制应用程序上的某些内容。
你在游戏中控制太空飞船的部分在这里：
override func touchesMoved(touches: Set<UITouch>, withEvent event: UIEvent?) {
for touch: AnyObject in touches{
let pointOfTouch = touch.locationInNode(self)
let previousPointOfTouch = touch.previousLocationInNode(self)
let amountDragged = pointOfTouch.x - previousPointOfTouch.x
player.position.x += amountDragged
if player.position.x > CGRectGetMaxX(gameArea) - player.size.width / 2{
player.position.x = CGRectGetMaxX(gameArea) - player.size.width / 2
}
if player.position.x < CGRectGetMinX(gameArea) + player.size.width / 2{
player.position.x = CGRectGetMinX(gameArea) + player.size.width / 2
所以任何人都可以编辑我的代码让我使用加速度计来控制船只，或者我们可以通过Skype与我交谈，我希望得到一些帮助。我的Skype是RoobTheMan。

不要担心它非常简单。首先，您必须在Swift文件的顶部执行
import CoreMotion，其他导入发生在外部类定义。
然后执行：

您可以稍后将 0.8 更改为其他内容 - ＆gt;数字越小，加速度阈值越低。您还可以将 x 更改为 y 或 z - 这取决于您要检测加速度的电话轴。
