SpriteKit app Absturz beim Laufen [SKAction moveByX: y: duration]

Question

Hier ist der Code des SKAction:

SKAction *movePipes = [SKAction moveByX:x y:y duration:d]; 
SKAction *removePipes = [SKAction removeFromParent]; 
SKAction *_movePipesAndRemove = [SKAction sequence:@[movePipes, removePipes]]; 

Und hier ist, wie ich die SKAction ausführen:

[object runAction:_movePipesAndRemove]; 

Ich habe verdreifachte, I bin mir sicher, dass der Fehler von hier kommt.

Hier ist der Crashlog:

Update:

Wie @Whirlwind angefordert, hier ist die gesamte spawnPipes Methode:

-(void)spawnPipes { 

    CGRect screenRect = [[UIScreen mainScreen] bounds]; 
    CGFloat screenWidth = screenRect.size.width; 
    CGFloat screenHeight = screenRect.size.height; 

    SKNode* pipePair = [SKNode node]; 
    pipePair.position = CGPointMake(screenWidth + 30, 0); 
    pipePair.zPosition = -10; 

    CGFloat y = arc4random() % (NSInteger)(screenHeight/3); 

    SKSpriteNode* firstPipe; 
    firstPipe = [SKSpriteNode spriteNodeWithTexture:[SKTexture textureWithImage:[UIImage imageWithContentsOfFile:@"/Library/Application Support/FlappyGo/firstpipe.png"]]]; 
    [firstPipe setScale:2]; 
    firstPipe.position = CGPointMake(0, y); 
    firstPipe.physicsBody = [SKPhysicsBody bodyWithRectangleOfSize:firstPipe.size]; 
    firstPipe.physicsBody.dynamic = NO; 
    firstPipe.physicsBody.categoryBitMask = pipeCategory; 
    firstPipe.physicsBody.contactTestBitMask = birdCategory; 

    [pipePair addChild:firstPipe]; 

    SKSpriteNode* secondPipe; 
    secondPipe = [SKSpriteNode spriteNodeWithTexture:[SKTexture textureWithImage:[UIImage imageWithContentsOfFile:@"/Library/Application Support/FlappyGo/secondPipe.png"]]]; 
    [secondPipe setScale:2]; 
    secondPipe.position = CGPointMake(0, y + firstPipe.size.height + 100); 
    secondPipe.physicsBody = [SKPhysicsBody bodyWithRectangleOfSize:secondPipe.size]; 
    secondPipe.physicsBody.dynamic = NO; 
    secondPipe.physicsBody.categoryBitMask = pipeCategory; 
    secondPipe.physicsBody.contactTestBitMask = birdCategory; 
    [pipePair addChild:secondPipe]; 

    SKNode* contactNode = [SKNode node]; 
    contactNode.position = CGPointMake(firstPipe.size.width + _bird.size.width/2, CGRectGetMidY(self.frame)); 
    contactNode.physicsBody = [SKPhysicsBody bodyWithRectangleOfSize:CGSizeMake(secondPipe.size.width, self.frame.size.height)]; 
    contactNode.physicsBody.dynamic = NO; 
    contactNode.physicsBody.categoryBitMask = scoreCategory; 
    contactNode.physicsBody.contactTestBitMask = birdCategory; 
    [pipePair addChild:contactNode]; 

    [pipePair runAction:_movePipesAndRemove]; 

    [_pipes addChild:pipePair]; 
} 

Answer 1

Sie sollten für verschiedene SKNodes neue SKActions erstellen.

Answer 2

Ich weiß, dass Sie Ihr Problem gelöst haben, aber ich dachte, diese Antwort könnte für jemanden in der Zukunft hilfreich sein. Eine einfache Möglichkeit, um die Aktion, die Sie wollen, ist wie folgt:

[object runAction:movePipes completion:^{ 
    [object removeFromParent]; 
}];
