我试图枚举我已经将其子类化为VillainSquirrel的所有精灵节点(如下所示),并且我正在尝试访问特定于VillainSquirrel类的属性...但是,我是陷入困境。
这是我得到的错误:
Tuple types '(SKNode, UnsafeMutablePointer<ObjCBool>)' and '()' have a different number of elements (2 vs. 0)
以下是我尝试通过节点枚举为VillainSquirrel的方法:
self.enumerateChildNodesWithName("villainType1") {
node as! VillainSquirrel, stop in
if (node.position.y > self.size.height){
node.brownMarker.position = CGPointMake(node.position.x, self.size.height - 10)
node.brownMarker.zPosition = 1
self.addChild(node.brownMarker)
}
}
这是我的VillainSquirrel Class(或者至少是它的开头):
class VillainSquirrel: SKSpriteNode {
var brownMarker = SKSpriteNode()
var brownMarkerVisible: Bool
override init(texture: SKTexture!, color: SKColor, size: CGSize) {
self.brownMarker.zPosition = 1
self.brownMarker.xScale = 0.25
self.brownMarker.yScale = 0.25
self.brownMarker = SKSpriteNode(imageNamed:"brownMarkerTrans.png")
...
非常感谢您提供的任何帮助!谢谢!
答案 0 :(得分:0)
想出来了!
self.enumerateChildNodesWithName("villainType1") {
node, stop in
let realnode = node as! VillainSquirrel
if (node.position.y > self.size.height){
realnode.brownMarker.position = CGPointMake(realnode.position.x, self.size.height - 10)
realnode.brownMarker.zPosition = 1
if (!realnode.brownMarkerVisible){
self.addChild(realnode.brownMarker)
realnode.brownMarkerVisible = true
}
}
else if (realnode.brownMarkerVisible){
realnode.brownMarkerVisible = false
realnode.brownMarker.removeFromParent()
}
}
我只需要在块中键入节点作为我的子类spriteNode,我无法通过节点执行,停止在
