问题描述
我已经使用SpriteKit(带有Objective-C)在XCode中创建了一个相当简单的(现在是实验性的)游戏".
I have created a fairly simple (at this point, experimental) "game" in XCode using SpriteKit (with Objective-C).
我知道如何手动创建一个SKSpriteNode对象并将其添加到SKScene中-但我正在尝试做相反的事情-在该对象中，我在XCode SceneKit GUI自身内部创建了Sprite(并为其命名)，现在我想在代码中 retriive .
I know how to manually create a SKSpriteNode object and add it to the SKScene - but I am kind of trying to do the opposite - where I created the sprite inside the XCode SceneKit GUI itself (and gave it a name), now I want to retreive it in my code.
在使用XCode的先前经验中，您可以通过声明@property UIOutlet [etc]，然后将其作为IB/Storyboard UI内部的参考插座进行连接来进行此操作-但我找不到在内部执行此操作的任何类似方法SpriteKit用户界面.
In prior experience with XCode, you would do this by declaring a @property UIOutlet [etc] and then connecting it as a referencing outlet inside the IB/Storyboard UI - but I can't find any similar way to do that inside the SpriteKit UI.
我可以创建一个属性(作为SKSpriteNode)，并将其命名为与SpriteKit对象相同的名称-并且它显示在SKScene下(在调试器中)，但是为"nil"-即未与我在XCode SpriteKit UI中创建的对象.
I can create a property (as an SKSpriteNode), and name it the same as my SpriteKit object - and it shows up under the SKScene (in the debugger), but is "nil" - i.e. is not "associated" with the object I created in the XCode SpriteKit UI.
我是否缺少某些东西-或这样做完全错误?:-O
Am I missing something - or doing this completely wrong? :-O
推荐答案
如果在Sprite Kit编辑器中设置了节点的name属性，则可以通过以下方式在Swift中访问该节点:
If you set the name property of a node in the Sprite Kit Editor, you can access the node, in Swift, by
if let node = self.childNodeWithName("NodeName") as? SKSpriteNode {
// Set up your sprite here
}
或
SKSpriteNode *node = (SKSpriteNode *)[self childNodeWithName:@"NodeName"];
在Obj-C中.
