Question

我最近对我的第一个应用程序进行了最后润色，但是我发现了一个让我发疯的错误！

游戏的目标是角色（猫），跳过障碍物但也必须避免飞过空中的鸟类，每次鸟儿飞过而没有接触时分数会增加。

如果在猫与鸟接触或猫未能跳过障碍物并且被推回到放置虚拟接触节点的屏幕的左边缘时接触，则游戏结束。

现在的错误...一切都按预期工作但是如果猫在半空中当一只鸟接触时碰撞将猫推离可见屏幕，在这个阶段玩家无法通过点击重置场景屏幕，只有当猫在屏幕上可见时，您才能通过点击一次重新播放场景并再次播放。

以下是我能想到的所有可能有用的代码，如果有人知道如何粉碎这个错误请告诉我。

override func didMoveToView(view: SKView) {

//details of the cat

    cat = SKSpriteNode(texture: catTexture1)
    cat.position = CGPoint(x: self.frame.size.width / 2.2, y: self.frame.size.height / 5.1 )
    cat.runAction(run, withKey: "runningAction")
    cat.physicsBody = SKPhysicsBody(circleOfRadius: cat.size.height / 2.0)
    cat.physicsBody!.dynamic = true
    cat.physicsBody!.allowsRotation = false
    cat.physicsBody?.categoryBitMask = catCategory
    cat.physicsBody?.collisionBitMask = crowCategory | worldCategory
    cat.physicsBody?.contactTestBitMask = crowCategory | contact2Category
    cat.physicsBody!.restitution = -10

    moving.addChild(cat)

//contact node increases score when bird makes contact

    var contact = SKSpriteNode(color: UIColor.clearColor(), size: CGSizeMake(1, 450))
    contact.position = CGPoint(x: self.frame.size.width / 3.3, y: self.frame.size.height / 2.0 )
    contact.physicsBody = SKPhysicsBody(rectangleOfSize: CGSizeMake(1, 450))
    contact.physicsBody!.dynamic = false
    contact.physicsBody!.allowsRotation = false
    contact.physicsBody?.categoryBitMask = scoreCategory
    contact.physicsBody?.contactTestBitMask = crowCategory

    self.addChild(contact)

//2nd contact node runs game over code

    var contact2 = SKSpriteNode(color: UIColor.redColor(), size: CGSizeMake(1, 450))
    contact2.position = CGPoint(x: self.frame.size.width / 4.0, y: self.frame.size.height / 2.0 )
    contact2.physicsBody = SKPhysicsBody(rectangleOfSize: CGSizeMake(1, 450))
    contact2.physicsBody!.dynamic = false
    contact2.physicsBody!.allowsRotation = false
    contact2.physicsBody?.categoryBitMask = contact2Category
    contact2.physicsBody?.contactTestBitMask = catCategory

    self.addChild(contact2)

//touch that initiates reset

override func  touchesBegan(touches: Set<NSObject>, withEvent event: UIEvent) {

    if ableToJump == true {
    if (moving.speed > 0){

        cat.physicsBody!.velocity = CGVectorMake(0, 0)
        cat.physicsBody!.applyImpulse(CGVectorMake(0, 30))

                } else if (canRestart) {
        resetLabelNode.hidden = true
        self.resetScene()
        }
    }
}

所以我在类似的帖子上找到了答案，他们建议的是在可见屏幕周围设置一个框架。我刚刚将以下代码添加到didMoveToView

    let frame = CGRectMake(255, 0, 515, self.frame.size.height)
    self.physicsBody = SKPhysicsBody(edgeLoopFromRect: frame)

我希望这有助于将来的某个人！
