skaction

I want to loop my background music with an SKAction but the music stops after one row when I switch to an other scene. Is there a way to start the loop and keep playing it over different scenes? Right now the code is placed in the init method of MyScene - is that the correct place? Maybe didFinishLaunchingWithOptions? Here is what I've tried: if (delegate.musicOn == YES && delegate.musicIsPlaying == NO) { SKAction *playMusic = [SKAction playSoundFileNamed:@"loop.wav" waitForCompletion:YES]; SKAction *loopMusic = [SKAction repeatActionForever:playMusic]; [self runAction:loopMusic]; delegate

I'm making a little game, and I'm now stuck with the following problem. I'm running an action (followPath type) on a particular node : let followTrack: SKAction = SKAction.followPath(ballPath!.CGPath, duration: ACTION_SPEED) movingBall.runAction(followTrack) But during the animation, if the node collide with another one (like a wall for exemple), the animation stops and there is no collision animation. I tried some things like : func didBeginContact(contact: SKPhysicsContact) { var firstBody: SKPhysicsBody = contact.bodyA var secondBody: SKPhysicsBody = contact.bodyB firstBody.node?

I am trying to make a repeating task where I can change the delay in which it repeats. Here is the current code I am using: var actionwait = SKAction.waitForDuration(self.wait) var actionrun = SKAction.runBlock({ self.count+=1 if (self.count % 2 == 0 && self.wait > 0.2){ self.wait -= 0.1 actionwait.duration = self.wait } for node in self.children{ if (node.isMemberOfClass(Dot)){ node.removeFromParent() } } var radius = CGFloat(arc4random_uniform(100) + 30) var newNode = Dot(circleOfRadius: radius) var color = self.getRandomColor() newNode.fillColor = color newNode.strokeColor = color newNode

I am looking at tutorial where things are defined like this: planes are sprites with dynamic physics bodies plane moving is done with actions by following the path there is contact detection between bullet and plane bullet is sprite and it has physics body set to be static (which is little unusual in my opinion) Here is the link to tutorial for more information. Questions: When we use actions to move physicsBodies is there a difference how we set body's dynamic property? Because bullet is static but still there is no problem for movement. When we have situation like this, where we don't need

I was hoping someone would be able to help me with this problem. I can't seem to find a way to assign a key to an SKAction for Sprite Kit for the removeActionWithKey method. I have also tried assinging the action to a key in a dictionary but the program didn't recognize the key assignment and thus returned a nil value. Here is what I tried to do: var textureanimation = SKAction.repeatActionForever(SKAction.animateWithTextures(_walkingframes, timePerFrame: 0.1)) var dictionary = ["animation": textureanimation] object.runAction(actionForKey("animation")) var sequence = [SKAction.moveTo(tap

I have the following custom SKAction working but as an EaseIn instead EaseOut. I want it to EaseOut! I have failed miserably to correct it using various easing equations found around the web. let duration = 2.0 let initialX = cameraNode.position.x let customEaseOut = SKAction.customActionWithDuration(duration, actionBlock: {node, elapsedTime in let t = Double(elapsedTime)/duration let b = Double(initialX) let c = Double(targetPoint.x) let p = t*t*t*t*t let l = b*(1-p) + c*p node.position.x = CGFloat(l) }) cameraNode.runAction(customEaseOut) Any help would be much appreciate. Thanks We can

How can I check whether a SKNode is already running an action before running an action on it? I want to be able to do something like... if (![mySprite isRunningActions]) { [mySprite runAction:action]; } If there is no built in way I'm thinking of creating a new BOOL property for holding the action state. Look at using named actions using any of the SKAction key-based methods. So you would instead run your action using the named equivalent to runAction: which is runAction:withKey: . If an action with the same key is already running, it is removed before the new one is added. Alternatively, use
