问题 EDIT: OK, so this happens even with an empty SpriteKit scene! What could be wrong here?? Why does iOS need 2 seconds to display SpriteKit scene?? EDIT 2: First time i click on tab bar to display view controller with SKScene it displays immediately, but every next time i try to navigate back to this view controller it will take it 2 seconds to display! I have a a tab bar controller in my app with multiple different viewControllers. One of them contains a SpriteKit scene, with a couple of nodes

问题 I have a circle and triangles inside and outside. I was looking through my character if it is not in a circle outside the circle touching triangles and vice versa. It does not matter if my character out of my circle it still happens. In fact if I'm in my circle and triangles outside my circle so my character should not touch them. How do I solve this? Does anyone have an idea? My Code : func AddCharacter() { BooCharacter.size = CGSize(width: 30, height: 30) BooCharacter.anchorPoint.y = 0

问题 this is my first SpriteKit game and I didn't had any problems with run action before so I tried but can't figure anything out, only thing I figure out is all code is fine but just run action don't execute some times and didn't seen any king of behaviour in that pattern. I I'm making 4 player board game and all 4 players have 4 pieces. the problem is with returning to home when ever any player piece kills other player's piece that piece comes back to home before it was working fine but I added

问题 I have an object on scene and my hero should not go through it, but it should be able to go inside of it, like a boat into the bay, surrounded by the other element. I tried all kinds of physicsBody having it have body with rectangle, texture, with polygon from path, but to no avail. I was reading somewhere that it is not possible to have a concave physicsBody, but only convex. I really need it to be able to be concave. Does anyone know how to resolve this? 回答1: You can create a concave

问题 I'm developing a small game in Swift 3 with SpriteKit and I want to move the enemies to the direction of the character, but at all times the enemies stop when they arrive at the character's initial position. I'm doing this: enemigo.name = "enemigo" enemigo.position = CGPoint(x: 280, y: 100) enemigo.xScale = 1/1 enemigo.yScale = 1/15 addChild(enemigo) let movement1 = CGVector( dx: (enemigo.position.x - personaje.position.x)*10, dy: (enemigo.position.y - personaje.position.y)*10 ) let

问题 I used a relatively small image (44pixel tall) and scaled it up to have a pixel art look. I tried to change the filtering mode to nearest so the anti-aliasing would disappear but it didn't. It appears with blurry edges. I tried the same with a background getting the same result. let myNode = SKSpriteNode() class GameScene: SKScene { func makeNode() { myNode.position = CGPoint(x: self.frame.size.width/2, y: self.frame.size.height/2) myNode.size = CGSize(width: 200, height: 200) myNode.texture

问题 I've been trying to play music in my SpriteKit game and used the AVAudioPlayerNode class to do so via AVAudioPCMBuffer s. Every time I exported my OS X project, it would crash and give me an error regarding audio playback. After banging my head against the wall for the last 24 hours I decided to re-watch WWDC session 501 (see 54:17). My solution to this problem was what the presenter used, which is to break the frames of the buffer into smaller pieces to break up the audio file being read.

问题 It seems that linear gravity field with vector method has been deprecated in Swift. There's a bunch of new SKFieldNode in this new language, but I can't seem to find one that resembles linear gravity. The property "direction" isn't even available in Swift. Maybe it can be done using this generic method customFieldWithEvaluationBlock but I'm not sure how. I'm new to SpriteKit. So, how can we make the same physics effect in Swift? 回答1: In Swift 2 (part of Xcode 7), SIMD vectors are available to

问题 My situation is that I have a GameMenuScene and after the user chooses a level, I want to present the LevelScene . But I do not want to have the previous GameMenuScene discarded because the LevelScene is actually a @property of GameMenuScene and whether or not the user completes the level is to be saved as a @property of LevelScene , which the GameMenuScene should be able to access after the user finishes or exits the level. If I simply use presentScene:transition , the GameMenuScene is

问题 I have a node with a dynamic physics body. And I would like to make it static and change its position when it comes in contact with another body. I managed to make the body static with the solution provided in this question: Sprite Kit failing assertion: (typeA == b2_dynamicBody || typeB == b2_dynamicBody) However if I change the position property of the node in one of the contact callback methods (e.g didBeginContact ) the new position is not taken into account. How could I achieve that? 回答1
