In Objective-C, using Sprite-Kit, I would successfully use something like the following code in Objective-C to bring up a new scene
if ([touchedNode.name isEqual: @"Game Button"]) {
SKTransition *reveal = [SKTransition revealWithDirection:SKTransitionDirectionDown duration:1.0];
GameScene *newGameScene = [[GameScene alloc] initWithSize: self.size];
// Optionally, insert code to configure the new scene.
newGameScene.scaleMode = SKSceneScaleModeAspectFill;
[self.scene.view presentScene: newGameScene transition: reveal];
}
In trying to port my simple game to Swift, so far I have this working...
for touch: AnyObject in touches {
let touchedNode = nodeAtPoint(touch.locationInNode(self))
println("Node touched: " + touchedNode.name);
let touchedNodeName:String = touchedNode.name
switch touchedNodeName {
case "Game Button":
println("Put code here to launch the game scene")
default:
println("No routine established for this")
}
But I do not know what code to write to actually transition to another scene. Question(s):
Thank you
To start with your second question, it's kind of up to you. If you wish to, you can continue to follow the Objective-C convention of having one class per file, although this isn't a requirement, and wasn't in Objective-C either. That being said, if you have a couple of classes that are tightly related, but aren't made up of much code, it wouldn't be unreasonable to have them grouped in a single file. Just do what feels right, and don't make a huge blob of code in a single file.
Then for your first questions... Yes, you had a good deal of it already. Basically, from where you got up to, you need to create the instance of GameScene through its size: initializer. From there, you just set the properties and call present.
override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
super.touchesBegan(touches, withEvent: event)
guard let location = touches.first?.locationInNode(self),
let scene = scene,
nodeAtPoint(location) == "Game Button" else {
return
}
let transition = SKTransition.reveal(
with: .down,
duration: 1.0
)
let nextScene = GameScene(size: scene.size)
nextScene.scaleMode = .aspectFill
scene.view?.presentScene(nextScene, transition: transition)
}
