问题 I am running a SpriteKit game on iPhone4, iOS7.1 When I select the regular RGBA888 texture atlas format it looks good, however, when I try to use RGBA444_COMPRESSED, all atlas textures are double the size as if the display is not retina.

问题 Are there any new options for converting a spritekit game to android? It seems the only options are to recode everything in Java or to use Cocos2D, LibGDX, etc. 回答1: Unfortunately ... no :{ And the cross-platform SpriteBuilder with the Apportable service that let you convert a Swift Cocos project to Android is no longer available (they got bought out by Google I believe). SpriteBuilder is still available on GitHub but it's not active afaik and is abandoned. So... what to do? I would focus on

问题 I changed the name of the app as it appears on the device under its icon by first changing the project name as suggested here. Suddenly on the simulator: the textures were not rendering correctly or could could not be found ( a large x appeared where the Sprtite Halo should of been) They were significantly freezes during run time The textures that did render were allot smaller After panicking a bit I undid the change and everything was back to normal. I then changed the name by changing the

问题 I tried to create a new subclass of SKScene "MainScene" like the one apple created the GameScene. I want to create more scene in addition to my "GameScene" but its not working.

问题 I'm writing an isometric game using SpriteKit and swift, and I'm having trouble with sprites for my sheep. They have a basic AI that randomly moves them around, but when it draws I get two big black horizontal lines instead of a sheep. I'm using init(rect:inTexture:) to take the first sub-image of my sprite sheet. I'm only doing one sheep to test my code. Here's my code: // // Animal.swift // Anointed // // Created by Jacob Jackson on 4/26/15. // Copyright (c) 2015 ThinkMac Innovations. All

问题 I've sent scores to the leaderboard with different test accounts but when I try to see the leaderboard I can only see the score from the account that I'm logged in.

问题 I've been searching for a solution to pause my SpriteKit game when the user "tabs down" the game. So far I found a solution where you use SKAction 's instead of NSTimer 's, this works as long as the time between actions stays the same. However, my NSTimer 's changes in speed. So I need to find another solution. I have a bunch of NSTimer 's located in GameScene -> didMoveToView NSTimer.scheduledTimerWithTimeInterval(0.2, target: self, selector: Selector("SpawnBullets"), userInfo: nil, repeats:
