I playing around with a Swift game from GitHub. I am attempting to add another button to the touchesBegan (newButton). Here is what I got so far:
override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
guard !gameOver else {
let gameOverLayer = childNodeWithName(StickHeroGameSceneChildName.GameOverLayerName.rawValue) as SKNode?
let location = touches.first?.locationInNode(gameOverLayer!)
let retry = gameOverLayer!.nodeAtPoint(location!)
if (retry.name == StickHeroGameSceneChildName.RetryButtonName.rawValue) {
print("Retry")
NSNotificationCenter.defaultCenter().postNotificationName("hideBanner", object: nil)
retry.runAction(SKAction.sequence([SKAction.setTexture(SKTexture(imageNamed: "button_retry_down"), resize: false), SKAction.waitForDuration(0.3)]), completion: {[unowned self] () -> Void in
self.restart()
})
}
return
}
guard !gameOver else {
let gameOverLayer2 = childNodeWithName(StickHeroGameSceneChildName.GameOverLayerName.rawValue) as SKNode?
let location2 = touches.first?.locationInNode(gameOverLayer2!)
let games = gameOverLayer2!.nodeAtPoint(location2!)
if (newButton.name == StickHeroGameSceneChildName.GamesButtonName.rawValue) {
print("New Button")
}
}
return
}
Here is the code for the buttons:
let retry = SKSpriteNode(imageNamed: "button_retry_up")
retry.name = StickHeroGameSceneChildName.RetryButtonName.rawValue
retry.position = CGPointMake(0, -180)
node.addChild(retry)
let newButton = SKSpriteNode(imageNamed: "button_games_up")
newButton.name = StickHeroGameSceneChildName.GamesButtonName.rawValue
newButton.position = CGPointMake(0, -360)
node.addChild(newButton)
There is the GitHub: https://github.com/phpmaple/Stick-Hero-Swift
I'm pretty new at Swift and need a little guidance. Thanks.

I have a maze game that I coded with swift that does not save levels. Currently, when the user closes the app, nothing is saved and the user has to start playing the game from level 1 again. I have a different .swift and .sks file for every level, so I am not sure how to save level data across classes/files.
I have tried to use UserDefaults, however, I am not sure how to save the "file path" to my level. I know that I need to implement something in my AppDelegate (using the applicationWillTerminate or applicationDidEnterBackground func), however, I am not sure what code (if any) I need to put in the scenes themselves to save this data. I have not worked with saving user data before, so help would be greatly appreciated!

Im trying to get the player sprite in my game to animate according to what it is doing, ie.. walking, attacking, resting.
I have the following files AgentNode and GameScene.
The sprite spawns and moves around as I want, just with the initial action that was in place when the sprite was added to the scene.
for example if I add the sprite with the "restingFrames" animation, it spawns correctly but when the sprite is moved, the animation is still using "restingFrames" and not "walkingFrames" as I want. Can't figure it out, please help.

I'm currently in the process of creating a new game that will feature two different balls/bubbles (a player and a enemy). I'm trying to get both of these to spawn randomly at different times kinda like this (ex. player, enemy, player, player, etc.(not in any order)) but random as the game goes on and after the player restarts the game. I'm having trouble trying to find a solution. I've tried a switch case but only either the player or enemy will spawn per game. Does anyone have a solution? If any other code is needed, I will provide it.
override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
/* Called when a touch begins */
if (gamestarted == false) {
gamestarted = true
/*Player and Enemy random spawner*/
ballSwitchCase()
/*Tap to start*/
tts.removeFromParent()
} else {
/*removed unnecessary code for question*/
}
func mainBallSpawner() {
/*Main ball*/
let spawn = SKAction.runBlock({
()in
self.creatingTheBall()
})
let delay = SKAction.waitForDuration(3.0)
let spawnDelay = SKAction.sequence([spawn, delay])
let spawnDelayForever = SKAction.repeatActionForever(spawnDelay)
self.runAction(spawnDelayForever, withKey: "spawnDelayForever")
let distance = CGFloat(self.frame.height + 170 + gameBall.frame.width)
let moveBalls = SKAction.moveToY(-distance, duration: NSTimeInterval(0.008 * distance))
let removeBalls = SKAction.removeFromParent()
moveAndRemoveBalls = SKAction.sequence([moveBalls, removeBalls])
}
func enemySpawner() {
/*Enemy*/
let spawnEnemy = SKAction.runBlock({
()in
self.creatingEnemyBall()
})
let delayEnemy = SKAction.waitForDuration(3.0)
let spawnDelayEnemy = SKAction.sequence([spawnEnemy, delayEnemy])
let spawnDelayEnemyForever = SKAction.repeatActionForever(spawnDelayEnemy)
self.runAction(spawnDelayEnemyForever, withKey: "spawnDelayEnemyForever")
let enemyDistance = CGFloat(self.frame.height + 170 + enemyBall.frame.width)
let moveEnemy = SKAction.moveToY(-enemyDistance, duration: NSTimeInterval(0.008 * enemyDistance))
let removeEnemy = SKAction.removeFromParent()
moveAndRemoveEnemy = SKAction.sequence([moveEnemy, removeEnemy])
}
func ballSwitchCase() {
let spawnRandomBall = arc4random_uniform(2)
switch spawnRandomBall {
case 0:
mainBallSpawner()
break
case 1:
enemySpawner()
break
default:
break
}
}
Your code can be much simpler

}
}
let wait = SKAction.waitForDuration(3)
let sequence = SKAction.sequence([addSomething, wait])
let repeatForever = SKAction.repeatActionForever(sequence)
self.runAction(repeatForever)
}
private func addBall() {
let ball = SKSpriteNode(imageNamed: "ball")
// set position etc...

}
private func addEnemy() {
let enemy = SKSpriteNode(imageNamed: "enemy")
// set position etc...
self.addChild(enemy)
}

I make a small game with swift and spritekit and I am currently working on the menu and made a custom Buttonclass called SKButtonNode as a Button which is a subclass of SKNode. When I click on the Button on my phone nothing happens though, even when I use "userInteractionEnabled = true". So why can't I see a "test2" when I touch a button but only see it if I hit next to a button?

startGame()
}

currentNode.defaultButton.hidden = false
}
}
It looks like you're never actually running your button's action. All you're doing when the button is pressed in touchesBegan is setting the .hidden property to true or false. Try something like this:
override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
let location = touches.first!.locationInNode(self)
let node = self.nodeAtPoint(location)
print("test2")
if (node.name == "startGameButton") {
let currentNode = node as! SKButtonNode
self.runAction(currentNode.action)
currentNode.activeButton.hidden = false
currentNode.defaultButton.hidden = true
}
}
I am new to SpriteKit.
I started working on a game where I want a menu of sprites that I can select from. When I select a particular sprite I want to then be able to tap on the screen and produce copies of them.
Here is a copy of my code I have trying.

self.addChild(button1)
let button2 = SKSpriteNode(imageNamed: "Monster2A.png")
button2.position = CGPointMake(300, 600)
button2.name = "Monster2A"
self.addChild(button2)
}
override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?)
{
let touch = touches
let location = touch.first!.locationInNode(self)
let node = self.nodeAtPoint(location)
if (node.name == "Monster1A")
{
for touch in touches
{
let touchLocation = touch.locationInNode(self)
let sprite = SKSpriteNode(imageNamed:"Monster1A")
sprite.xScale = 0.5
sprite.yScale = 0.5
sprite.position = touchLocation
let action = SKAction.rotateByAngle(CGFloat(M_PI), duration:1)
sprite.runAction(SKAction.repeatActionForever(action))
self.addChild(sprite)
}
}
if (node.name == "Monster2A")
