【问题描述】:
我的 Sprite Kit 游戏在游戏结束时崩溃。这发生在 tvOS 9.1 和 iOS 9.2 上。之前,我让它在 iOS 9.1 上运行而没有崩溃。
这似乎是一个 OpenGL 的问题,但是当我在 Xcode 中搜索该函数时,它什么也没找到。
不幸的是,错误在控制台中出现并不一致。这是错误:
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 在崩溃时也指向 AppDelate 类:
class AppDelegate: UIResponder, UIApplicationDelegate
启用断点异常后,Xcode 会指向这一行。这是一个声音文件的常数:
let soundHitLava = SKAction.playSoundFileNamed("DrownFireBug.mp3",
waitForCompletion: false)
来自异常断点的更多信息:

这是 GameScene 中的 GameOver 函数:
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
}
}
【问题讨论】:
-
我们可能需要更多代码。如果您认为这是一个框架错误,请提交雷达:radar.apple.com
-
谢谢。但我不确定代码在哪里。它在 Game Over 时崩溃,所以我将在我的问题中添加该功能。
-
您是否启用了异常中断?如果没有,请转到菜单 Debug > Breakpoints > Create Exception Breakpoint...
-
@0x141E 是的,当我启用异常断点时,它会在声音文件常量
let soundHitLava = SKAction.playSoundFileNamed("DrownFireBug.mp3", waitForCompletion: false)上崩溃我不知道为什么它会在那里崩溃,因为文件在捆绑包中。我会将错误添加到我的问题中。 -
它看起来和this 一样的错误发生在 OP 向场景中添加发射器时。我猜这是一个操作系统错误。
