Objective c SpriteKit鼠标移动不工作
我知道以前有人问过这个问题,但我认为答案可能需要更新,因为它目前在使用Xcode 8.3.3 for Mac OS的SpriteKit中不起作用。读了这篇文章后,我意识到以前可以在AppDelegate中完成的事情现在应该在ViewController中完成,但它不起作用。有人对为什么这不起作用有什么建议吗?下面是我的各种课程的样子: ViewController.mObjective c SpriteKit鼠标移动不工作,objective-c,macos,sprite-kit,mouseevent,Objective C,Macos,Sprite Kit,Mouseevent,我知道以前有人问过这个问题,但我认为答案可能需要更新,因为它目前在使用Xcode 8.3.3 for Mac OS的SpriteKit中不起作用。读了这篇文章后,我意识到以前可以在AppDelegate中完成的事情现在应该在ViewController中完成,但它不起作用。有人对为什么这不起作用有什么建议吗?下面是我的各种课程的样子: ViewController.m #import "ViewController.h" #import "GameScene.h" @implementatio

如果要将第一响应程序设置为
skView
,则需要将其设置为skView.scene
,以便鼠标响应的是场景实例,而不是视图实例
步骤1:将窗口代码移动到viewdide
步骤2:使用[self.skView.window makeFirstResponder:self.skView.scene]将第一响应者更改为场景代码>
之所以需要在viewdideappear
事件中执行此操作,是因为SKView
的window
在viewdideload
事件期间为nil
。您是否在Swift,self.skView.window!中完成了此操作!。SetAcceptedMouseMotations=true
对您可能会失败(Swift是一种高级语言,我建议您使用它)
几周前你不是问了同样的问题吗?是的。我完全忘记了。不管怎样,都没有人给出答案。我将删除旧问题。如果您感兴趣,我可以向您展示如何使用Swift。我记得你的老话题,因为我在Swift中发布了代码,然后在意识到你想在Objective-C中使用它后将其删除。我认为,无论你是用Objective-C还是Swift编写它,概念都是一样的。是的,那太好了。我可以把Swift翻译成Objective-C,像这样吗<代码>[self.skView.window makeFirstResponder:self.skView.scene]代码>它不工作。我在ViewController.m btw.Don’不要在did load事件中执行窗口代码,在viewdide出现event中执行加载时SKView的窗口不是根视图控制器的窗口,在视图出现后,您知道您的窗口在根视图控制器上,因为您可以看到它。我理解。谢谢
