ios – Sprite Kit停止冲动

每次当屏幕被点击时,我想增加一个CGFloat.
浮点数具有设定的最大值和最小值.
我试图通过这个建议： StackOverflow

然而,这只会在触摸完成后增加CGFloat,或者达到最大值.我想在触摸过程中增加CGFloat,这意味着您触摸跳转/ CGFloat的时间越长.

这个问题可能在冲动之中,在应用之后你不能改变它.这意味着,在“玩家”获得20的冲动之后,屏幕更长时间的触动,浮动可能会增加,但冲动不会.

如果你看看我当前的代码,那么当屏幕被触摸时,脉冲被设置为最大值,但如果释放该动作应该被删除.但是,它不行,冲动不会停止.

我知道您可以在按下按钮之后将身体的速度设置为一个值,如果按下速度已经将速度返回到0,那么它会停止它的“跳跃”,但是看起来不太顺利有冲动.

有人有解决方案吗？

struct Constants {
 
static let minimumJumpForce:CGFloat = 20.0
static let maximumJumpForce:CGFloat = 60.0
}
 
class GameScene: SKScene,SKPhysicsContactDelegate {
 
var force: CGFloat = 20.0
 
func longPressed(longPress: UIGestureRecognizer) {
 
    if (longPress.state == UIGestureRecognizerState.Began) {
 
        println("Began")
 
        self.pressed = true
 
        let HigherJump = SKAction.runBlock({Player.physicsBody?.applyImpulse(CGVectorMake(0,Constants.maximumJumpForce))})
 
        self.runAction(HigherJump,withKey:"HighJump")
 
    }else if (longPress.state == UIGestureRecognizerState.Ended) {
 
        println("Ended")
 
        self.pressed = false
 
        self.removeActionForKey("HighJump")
 
    }
 
}
 
override func touchesBegan(touches: Set<NSObject>,withEvent event: UIEvent) {
    /* Called when a touch begins */
 
    for touch in (touches as! Set<UITouch>) {
        let location = touch.locationInNode(self)
 
    }
}
 
override func touchesEnded(touches: Set<NSObject>,withEvent event: UIEvent) {
    for touch in (touches as! Set<UITouch>) {
        let location = touch.locationInNode(self)
 
}
}
 
override func update(currentTime: CFTimeInterval) {
    /* Called before each frame is rendered */
 
}

解决方法

1.从基于SpriteKit的Xcode模板创建“游戏”
将列出的代码复制到GameScene类中

import SpriteKit
 
class GameScene: SKScene,SKPhysicsContactDelegate {
 
    var location = CGPoint()
    var floorSize = CGSize()
    var floorColor = UIColor()
    var player = SKSpriteNode()
 
    override func didMoveToView(view: SKView) {
 
        view.showsFPS = true;
        view.showsNodeCount = true;
        view.showsDrawCount = true;
 
        self.physicsBody = SKPhysicsBody(edgeLoopFromRect: self.frame)
        self.physicsBody?.categoryBitMask = 1
        self.physicsBody?.contactTestBitMask = 1
        self.physicsWorld.gravity = CGVectorMake(0,0)
        self.physicsWorld.contactDelegate = self;
 
        location = CGPoint(x:CGRectGetMidX(self.frame),y:CGRectGetMidY(self.frame))
 
        player = SKSpriteNode(imageNamed:"Spaceship")
        player.physicsBody = SKPhysicsBody(rectangleOfSize: CGSize(width: 320,height: 320))
        player.physicsBody?.categoryBitMask = 1
        player.physicsBody?.collisionBitMask = 1
        player.physicsBody?.contactTestBitMask = 1
        player.physicsBody?.linearDamping = 0;
        player.xScale = 1
        player.yScale = 1
        player.position = location
        self.addChild(player)
 
    }
 
    override func touchesBegan(touches: Set<UITouch>,withEvent event: UIEvent?) {
        self.physicsWorld.gravity = CGVectorMake(0,0)
        let direction = Float(1.5708)//Float(player.zRotation) + Float(M_PI_2)
        player.physicsBody?.applyForce(CGVector(dx: 150000*CGFloat(cosf(direction)),dy: 150000*CGFloat(sinf(direction))))
    }
 
    override func touchesEnded(touches: Set<UITouch>,-7.9)
    }
 
}

3.运行应用程序

这应该给你’Jump’游戏的起点:)
