Swift: Override can only be specified on class members
提问by William Clark
In my GameScene.swift file, there are errors that are causing the build to fail.
在我的 GameScene.swift 文件中，存在导致构建失败的错误。
override func touchesBegan(touches: NSSet, withEvent event: UIEvent) {
/* Called when a touch begins */
for touch: AnyObject in touches {
let location = touch.locationInNode(self)
let sprite = SKSpriteNode(imageNamed:"Spaceship")
sprite.xScale = 0.5
sprite.yScale = 0.5
sprite.position = location
let action = SKAction.rotateByAngle(CGFloat(M_PI), duration:1)
sprite.runAction(SKAction.repeatActionForever(action))
self.addChild(sprite)
}
}
override func update(currentTime: CFTimeInterval) {
/* Called before each frame is rendered */
}
I am told that 'override can only be specified on class members'.
我被告知“只能在班级成员上指定覆盖”。
How should I fix this?
我应该如何解决这个问题？

let location = touch.locationInNode(self)
let sprite = SKSpriteNode(imageNamed:"Spaceship")
sprite.xScale = 0.5
sprite.yScale = 0.5
sprite.position = location
let action = SKAction.rotateByAngle(CGFloat(M_PI), duration:1)
sprite.runAction(SKAction.repeatActionForever(action))
self.addChild(sprite)
}
}
func update(currentTime: CFTimeInterval) {
/* Called before each frame is rendered */
}
}
There is also a syntax error at the bottom mentioned in the comment section.
评论部分提到的底部还有一个语法错误。

add a "}" before the line
在行前添加“}”
func touchesBegan(touches: NSSet, withEvent event: UIEvent) {

there is 2 answers one is that you used override somewhere you can't otherwise your missing a braket or a round braket
有 2 个答案，一个是您在某处使用了覆盖，否则您将错过刹车或圆形刹车
