Sprite Kit游戏在tvOS 9.1和iOS 9.2上游戏崩溃

问题描述:

我有一个Sprite Kit游戏,当游戏结束时会崩溃。这发生在tvOS 9.1和iOS 9.2上。之前,我在iOS 9.1上运行时没有崩溃。Sprite Kit游戏在tvOS 9.1和iOS 9.2上游戏崩溃

它似乎是一个OpenGL的问题,但是当我在Xcode中搜索函数时,它没有提供任何东西。

不幸的是,出现在控制台中的错误并不一致。这里的错误:

Jet: draw_indexed: indexType must be 'unsigned_int' or 'unsigned_short' 
Assertion failed: (indexType == jet_component_type_unsigned_int || indexType 
== jet_component_type_unsigned_short), function draw_indexed, file 
/BuildRoot/Library/Caches/com.apple.xbs/Sources/Jet_Sim/Jet- 
1.50.1/Jet/jet_context_OpenGL.mm, line 1426. 

Xcode中还指出,AppDelate类时崩溃:

class AppDelegate: UIResponder, UIApplicationDelegate

启用断点例外,Xcode中指向此行。这是一个声音文件的常数:

let soundHitLava = SKAction.playSoundFileNamed("DrownFireBug.mp3", 
waitForCompletion: false) 

从异常断点更多信息:

这里是在GameScene的GAMEOVER功能:

override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) { 

    #if os(tvOS) // tvOS 
    if startTouchX == 0.0 { 
     startTouchX = (touches.first?.locationInNode(self).x)! 
    } 
    #endif 

    switch gameState.currentState { 
    case is WaitingForTap: 
    gameState.enterState(WaitingForBomb) 
    // Switch to playing state 
    self.runAction(SKAction.waitForDuration(2.0), 
     completion:{ 
     self.gameState.enterState(Playing) 
    }) 

    case is GameOver: 
    let newScene = GameScene(fileNamed:"GameScene") 
    newScene!.scaleMode = .AspectFill 
    let reveal = SKTransition.flipHorizontalWithDuration(0.5) 
    self.view?.presentScene(newScene!, transition: reveal) 

    self.saveHighScore("com.prismstudios.jumpingcarl.leaderboard", score: GameState.sharedInstance.highScore) 

    GameState.sharedInstance.highScore = 0 
    GameState.sharedInstance.coins = 0 

    default: 
     break 
    } 
    } 

这里是GAMEOVER类:

import SpriteKit 
import GameplayKit 

class GameOver: GKState { 
    unowned let scene: GameScene 

init(scene: SKScene) { 
self.scene = scene as! GameScene 
super.init() 
} 

override func didEnterWithPreviousState(previousState: GKState?) { 
if previousState is Playing { 

    scene.playBackgroundMusic("SpaceGame.caf") 
    let gameOver = SKSpriteNode(imageNamed: "GameOver") 
    gameOver.position = scene.getCameraPosition() 
    gameOver.zPosition = 10 
    scene.addChild(gameOver) 

    let explosion = scene.explosion(6.0) 
    explosion.position = gameOver.position 
    explosion.zPosition = 11 
    scene.addChild(explosion) 
    scene.runAction(scene.soundExplosions[3]) 
    scene.screenShakeByAmt(200) 

    scene.addChild(button) 
    } 
} 

override func isValidNextState(stateClass: AnyClass) -> Bool { 
    return stateClass is WaitingForTap.Type 
} 
}

我们可能需要更多的代码。如果您认为这是一个框架错误,请提供雷达:http://radar.apple.com –

谢谢。但我不确定代码中的位置。它在Game Over上崩溃,所以我会在我的问题中添加该函数。 – Paul

@Mr_Pouet更新! – Paul

我发现的答案是降低SKEmitterNode的出生率和粒子排放,因为这会导致游戏崩溃。

在GameScene.swift:

func explosion(intensity: CGFloat) -> SKEmitterNode { 
    let emitter = SKEmitterNode() 
    let particleTexture = SKTexture(imageNamed: "spark") 

    emitter.zPosition = 2 
    emitter.particleTexture = particleTexture 

    //LOWER the particleBirthRate and numParticlesToEmit 
    emitter.particleBirthRate = 50; //4000 * intensity 
    emitter.numParticlesToEmit = 50; //Int(400 * intensity) 

    .... 
} 

分别一旦降低到50,那么游戏将不会崩溃。我不知道为什么会发生这种情况,但苹果目前正在研究这个问题,并被认为是一个错误。
