Question

我无法让飞船和敌人2发生碰撞，它在视觉上或调试区域均未发生碰撞的任何迹象。两者都是通过屏幕触摸来控制的，而其他则不是。

宇宙飞船将与敌人和金币相撞。敌人2将与敌人碰撞。我在底部标出了我认为是造成此问题的两个部分。

编码的新手，因此在视觉帮助下进行详尽的解释将不胜感激。

override func didEvaluateActions() {
    checkCollisions()
}



func spaceshipHit(goldCoin: SKSpriteNode) {
   // added for score jan 13
    goldcoinCount += 1
    goldCoin.removeFromParent()
}

func spaceshipHit2(enemy: SKSpriteNode) {
    enemy.removeFromParent()
}



func spaceshipHit(enemy: SKSpriteNode) {
    invincible = true
    // added for score attempt jan 13
    lives -= 1
    print(lives)
    enemy.removeFromParent()
    let blinkTimes = 10.0
    let duration = 3.0
    let blinkAction = SKAction.customAction(withDuration: duration) { node, elapsedTime in
        let slice = duration / blinkTimes
        let remainder = Double(elapsedTime).truncatingRemainder(
            dividingBy: slice)
        node.isHidden = remainder > slice / 2
    }
    let setHidden = SKAction.run() { [weak self] in
        self?.spaceship.isHidden = false
        self?.invincible = false
    }
    spaceship.run(SKAction.sequence([blinkAction, setHidden]))

}

这是我认为未激活的代码块。

func spaceshipHit(enemy2: SKSpriteNode) {
    invincible = true
    lives -= 1
    print(lives)

    let blinkTimes = 10.0
    let duration = 3.0
    let blinkAction = SKAction.customAction(withDuration: duration) { node, elapsedTime in
        let slice = duration / blinkTimes
        let remainder = Double(elapsedTime).truncatingRemainder(
            dividingBy: slice)
        node.isHidden = remainder > slice / 2
    }
    let setHidden = SKAction.run() { [weak self] in
        self?.spaceship.isHidden = false
        self?.invincible = false
    }
    spaceship.run(SKAction.sequence([blinkAction, setHidden]))

}


func checkCollisions() {

    var hitGoldCoins: [SKSpriteNode] = []
    enumerateChildNodes(withName: "goldCoin") { node, _ in
        let goldCoin = node as! SKSpriteNode
        if goldCoin.frame.intersects(self.spaceship.frame) {
            hitGoldCoins.append(goldCoin)
        }
    }

    for goldCoin in hitGoldCoins {
        spaceshipHit(goldCoin: goldCoin)
    }

    if invincible {
        return
    }

    var hitEnemiesToEnemies: [SKSpriteNode] = []
    enumerateChildNodes(withName: "enemy") { node, _ in
        let enemy = node as! SKSpriteNode
        if node.frame.insetBy(dx: 20, dy: 20).intersects(
        self.enemy2.frame) {
        hitEnemiesToEnemies.append(enemy)
        }
    }

    for enemy in hitEnemiesToEnemies {
        spaceshipHit2(enemy:enemy)
    }


    var hitEnemies: [SKSpriteNode] = []
    enumerateChildNodes(withName: "enemy") { node, _ in
        let enemy = node as! SKSpriteNode
        if node.frame.insetBy(dx: 20, dy: 20).intersects(
            self.spaceship.frame) {
            hitEnemies.append(enemy)

        }
    }

    for enemy in hitEnemies {
        spaceshipHit(enemy: enemy)
    }

    if invincible {
        return
    }

这是另一个可疑的部分。

    var hitEnemies2: [SKSpriteNode] = []
    enumerateChildNodes(withName: "enemy2") { node, _ in
        let enemy2 = node as! SKSpriteNode
        if enemy2.frame.intersects(
            self.spaceship.frame) {
            hitEnemies2.append(enemy2)
        }
    }


    // this is the section that trys to get the ship to hit shadow enemy
    /*var hitEnemies2: [SKSpriteNode] = []
    enumerateChildNodes(withName: "enemy2") { node, _ in
        let enemy2 = node as! SKSpriteNode
        if node.frame.insetBy(dx: 20, dy: 20).intersects(
            self.spaceship.frame) {
            hitEnemies2.append(enemy2)
        }
    }
    */


    for enemy2 in hitEnemies2 {
        spaceshipHit(enemy2: enemy2)
    }


}

Answer 1

根据我所看到的，您永远不会将“ enemy2”分配给敌人的名字，所以enumerateChildNodes(withName: "enemy2") { node, _ in let enemy2 = node as! SKSpriteNode if enemy2.frame.intersects( self.spaceship.frame) { hitEnemies2.append(enemy2) } }

应为空，表示未命中任何节点。
