所以,我正在为iOS制作一款游戏,除了现在我的touchesBegan功能导致错误之外,所有这些都完成了。这就是我现在的功能:
override func touchesBegan(touches: NSSet, withEvent event: UIEvent) {
var doo = SKAction.removeFromParent()
/* Called when a touch begins */
for touch: AnyObject in touches {
let location = touch.locationInNode(self)
if GameOver{
var gameScene = EasyScene(size: self.size)
gameScene.scaleMode = SKSceneScaleMode.AspectFill
self.scene!.view?.presentScene(gameScene)
}
else{
if red.containsPoint(location){ // This is Line A
//takeOut(red)
red.removeFromParent()
score++
scoreNode.text = String(score)
print("-hi")
}
if red1.containsPoint(location){
red1.removeFromParent()
score++
scoreNode.text = String(score)
//takeOut(red1)
print("-hel")
}
if red2.containsPoint(location){
red2.removeFromParent()
score++
scoreNode.text = String(score)
//takeOut(red2)
print("-hell")
}
if red3.containsPoint(location){
red3.removeFromParent()
score++
scoreNode.text = String(score)
//takeOut(red3)
print("-hello")
}
if red4.containsPoint(location){
red4.removeFromParent()
//takeOut(red4)
score++
scoreNode.text = String(score)
print("-hellow")
}
if red5.containsPoint(location){
red5.removeFromParent()
score++
scoreNode.text = String(score)
// takeOut(red5)
print("-hellowor")
}
if blue.containsPoint(location){
GameOver = true
}
if blue1.containsPoint(location){
GameOver = true
}
if blue2.containsPoint(location){
GameOver = true
}
}
}
}
问题是当 GameOver为假时:我在屏幕上触摸的任何内容都会导致崩溃。如果我触摸屏幕(特别是没有spriteNode),它指向标有&#34的行;这是A行和#34;然而,如果我点击屏幕上实际存在的节点,游戏将崩溃并指向我按下的spriteNode说同样的事情:
fatal error: unexpected nil while unwrapping optional value
当 GameOver == true toouchesBegan工作正常时
答案 0 :(得分:0)
我的游戏崩溃的原因是因为我已经在我的应用程序初始启动后5秒钟已经编程执行的函数中声明了我的精灵。但是我发现游戏运行正常,因为我的红色精灵是在didMoveToView
中声明的
