这是我目前的触摸位置代码

override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
   /* Called when a touch begins */

    for touch in touches {
        let location = touch.locationInNode(self)

        var bullet = SKSpriteNode(imageNamed: "bullet")
        bullet.position = cannon.position
        bullet.size = CGSize(width: 35, height: 35)

        //physics
        bullet.physicsBody = SKPhysicsBody(circleOfRadius: bullet.size.width/2)
        bullet.physicsBody?.categoryBitMask = PhysicsCategory.bullet
        bullet.physicsBody?.collisionBitMask = PhysicsCategory.enemy
        bullet.physicsBody?.contactTestBitMask = PhysicsCategory.enemy
        bullet.name = "bullet"
        bullet.physicsBody?.affectedByGravity = false

        self.addChild(bullet)

        var dx = CGFloat(location.x - cannon.position.x)
        var dy = CGFloat(location.y - cannon.position.y)

        let magnitude = sqrt(dx * dx …

这是我的第一个Android应用程序,我正在从iOS开发过渡.我正在尝试改变其他活动.但是,我的新空活动需要几秒钟(大约3秒)才能显示.

这是我要转发到新活动的代码:

public void openStats(View v) {
    startActivity(new Intent(MainActivity.this, StatsActivity.class));
}

这是我对我的新活动的创建:

public class StatsActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.stats_page);
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
    }
}

我无法弄清楚为什么这么长时间？我也正在测试三星Galaxy S5.

这是打开新活动时的日志:

当用户调用restorePurchases()时,即使他们不拥有它,也会恢复非耗材com.premium.以下是负责恢复购买和购买IAP的功能.这只是非耗材IAP的问题.购买没有问题.如果用户尝试购买他们已经拥有的IAP,则只需恢复.感谢您关注此事.

func restorePurchases() {
    SKPaymentQueue.default().add(self)
    SKPaymentQueue.default().restoreCompletedTransactions()
}

func paymentQueueRestoreCompletedTransactionsFinished(_ queue: SKPaymentQueue) {
    print("transactions restored")

    for transaction in queue.transactions {
        let t: SKPaymentTransaction = transaction 

        let prodID = t.payment.productIdentifier as String
        print("starting restoring")
        switch prodID {
        case "com.premium":
            print("restoring ads")
            removeAds()
        case "com.cash":
            print("we dont restore coins")
        case "com.level":
            print("we dont restore levels")
        default:
            print("can't restore")
        }
    }

这也是我的支付队列.

func paymentQueue(_ queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]) {
    print("add paymnet")

    for transaction:AnyObject in transactions {
        let trans = transaction as! SKPaymentTransaction
        print(trans.error) …
