-mouseMoved OSX does not get called in a sprite kit SKScene

问题

The following responder (defined in NSResponder) does not get called in an SKScene in OSX:

-(void) mouseMoved:(NSEvent *)theEvent {
    DLog(@"TEST");
}

I have said the window to accept mouse moved events in the app delegate.

_window.acceptsMouseMovedEvents = YES;

Thank you in advance.

SOLUTION:

Add to the app delegate:

_window.acceptsMouseMovedEvents = YES;
[_window makeFirstResponder:self.skView.scene];

_window.acceptsMouseMovedEvents = YES;
[_window makeFirstResponder:self.skView.scene];

回答2:

In swift

window.acceptsMouseMovedEvents = true;
window.makeFirstResponder(self.skView.scene)

回答3:

You can get at the window object and set it from the scene.

in Swift: override func willMove(from view: SKView) { self.view!.window?.acceptsMouseMovedEvents = true }

The above answers either make too many assumptions about what’s outside of your SKScene, or add a touch of unnecessary hackiness by messing with the responder chain.

SKView is a subclass of UIView. It inherits, therefore, the viewDidMoveToWindow: method. You can activate mouse-moved events for all your SKViews with a simple extension.

extension SKView {
    open override func viewDidMoveToWindow() {
        super.viewDidMoveToWindow()
        window?.acceptsMouseMovedEvents = true
    }
}
