我试图在一个函数中添加SKSpriteNodes到视图中,但是Xcode不允许我这样做。它给出了错误提示"使用未解决的标识符 'self'"。
func indicate() {
if test == 0 {
var large = ((CGFloat(largest)*54) - 29) - selectedNode.position.x
var small = selectedNode.position.x - ((CGFloat(smallest)*54) - 29)
indicatorRight.position = CGPointMake(selectedNode.position.x + large, selectedNode.position.y)
indicatorRight.userInteractionEnabled = true
indicatorRight.zPosition = 0.5
indicatorLeft.position = CGPointMake(selectedNode.position.x - small, selectedNode.position.y)
indicatorLeft.userInteractionEnabled = true
indicatorLeft.zPosition = 0.5
println(indicatorLeft.position)
// println(smallest)
self.addChild(indicatorRight)
self.addChild(indicatorLeft)
}
}
