Swift中的ScoreLabel游戏无法正常工作

Question

我试图让一个分数标签在我的游戏中起作用，我希望每当＆＃34;英雄＆＃34;时，分数会增加1。通过＆＃34;墙＆＃34;我已经得到了它，所以数字0在得分所在的角落里是最高的，当我开始游戏时，它会计算但速度太快。因为在墙上甚至还没到，我已经在示例中：67分。关于如何获得它的任何建议，以便当英雄通过墙壁时它给出1点或者如果墙壁到达点x我得到1点？

它有点像飞鸟！

这是代码

import SpriteKit

var movingGround: CSMovingGround!

CSWall代码（墙）

import Foundation
import SpriteKit

class CSWall: SKSpriteNode {

let WALL_WIDTH: CGFloat = 30.0
let WALL_HEIGHT: CGFloat = 50.0
let WALL_COLOR = UIColor.blackColor()

override init() {
    super.init(texture: nil, color: WALL_COLOR, size: CGSizeMake(WALL_WIDTH, WALL_HEIGHT))
    startMoving()
}

required init?(coder aDecoder: NSCoder) {
    fatalError("init(coder:) has not been implemented")
}

func startMoving() {
    let moveLeft = SKAction.moveByX(-300, y: 0, duration: 1)
    runAction(SKAction.repeatActionForever(moveLeft))
}


}

在游戏中生成墙的代码

import SpriteKit

class CSWallGenerator: SKSpriteNode {

var generationTimer: NSTimer?

func startGeneratingWallsEvery(seconds: NSTimeInterval) {
    generationTimer = NSTimer.scheduledTimerWithTimeInterval(seconds, target: self, selector: "generateWall", userInfo: nil, repeats: true)


}

func generateWall() {
    var scale: CGFloat
    let rand = arc4random_uniform(2)
    if rand == 0 {
        scale = -1.0
    } else {
        scale = 1.0
    }

    let wall = CSWall()
    wall.position.x = size.width/2 + wall.size.width/2
    wall.position.y = scale * (kCSGroundHeight/2 + wall.size.height/2)
    wall.physicsBody = SKPhysicsBody(rectangleOfSize: wall.size)
    wall.physicsBody?.dynamic = false
    addChild(wall)

}

}
