问题 I like my code to be explicit so I want to remove the storyboard file and create SKView programmatically. What I have tried so far: I created a SpriteKit game project in xcode . Deleted the storyboard file. Deleted sroryboard property from Info.plist Added this code found in an example to the AppDelegate : - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { _window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

问题 in SpriteKit we detect the in the didBeginContact method. but this looks a bit stupid to do something like that: func didBeginContact(contact: SKPhysicsContact) { if let contactA = contact.bodyA.node?.name { if let contactB = contact.bodyB.node?.name { //now that we have safely unwrapped these nodes, we can operate on them if contactA == "ball" { collisionBetweenBall(contact.bodyA.node!, object: contact.bodyB.node!) } else if contactB == "ball" { collisionBetweenBall(contact.bodyB.node!,

问题 I am building a game using Spritekit and am trying to build a raycast that will connect the player with the point where the player tapped. It will be like a rope that connects the player to the point where he or she tapped. For example if a player taps at the point x: 0, y: 0 then it will become a rope that connects both things with each other. With the time the rope will become shorter and the player will be dragged against it. The player does have a physicsbody. When the player releases the

问题 I have searched around the internet / StackOverflow for the past few days without much success in finding an answer to a few questions that I believe are intertwined in some way. How do I prevent my game from freezing when it is rendering an SKPhysicsBody from a texture? Why are my physics bodies sometimes not created at all, and why are they sometimes the wrong shapes? Below is the code I am using to try and generate these pillars (image attached at the bottom of the post. There are roughly

问题 I'm adding an anchor to my sceneView in the world origin position: let configuration = ARWorldTrackingConfiguration() sceneView.session.run(configuration) sceneView.session.add(anchor: ARAnchor(name: "world origin", transform: matrix_identity_float4x4)) sceneView.presentScene(SKScene()) I then choose to show a SKLabelNode at my anchor position func view(_ view: ARSKView, nodeFor anchor: ARAnchor) -> SKNode? { // Create and configure a node for the anchor added to the view's session. let

问题 I am attempting to generate a random X position for a simple object, in order to have it bounce back and forth inside the scene in a Swift SpriteKit game. The repeatForever action should generate a random value and then move the object (a circle) multiple times to different locations, left and right. However, it acts only one time. It is as if the random function, which works correctly, is called only one time, and the action then simply continues to move the object to the same position
